Release Log

• 2.1.0 - Unreleased

  East Asian name support

  • Add the Chinese locale pack locales.ZH — opt-in Han segmentation for unspaced names like 毛泽东, with the surname vocabulary it needs. A pack rather than a default because a Chinese surname list corrupts the Japanese names written in the same characters (高橋一郎 would split 高 + 橋一郎); Japanese data goes through locales.JA and its segmenter instead. It sets no name order, since native-script Han already reads family-first without it (#271)
  • Add Lexicon.surnames, Policy.script_orders, Policy.segment_scripts, the Script enum and the DEFAULT_SCRIPT_ORDERS constant to the public API. This is the first behavior nameparser keys on the script a name is written in; it is allowed only where the script itself settles a convention, never as a proxy for guessing the language (#271)
  • Add Lexicon.honorific_tails, the vocabulary the glued-honorific peel matches: entries that may be split off the END of a name token, matched longest-first. Deliberately a separate, narrower set than the spaced honorific vocabulary — a glued tail has no token boundary to lean on — and every entry is also a suffix_words entry, since the peeled piece is claimed by ordinary suffix classification. That subset rule is enforced, so extend both fields in the one call — Lexicon.default().add(suffix_words={"ちゃま"}, honorific_tails={"ちゃま"}); adding to honorific_tails alone raises ValueError naming the orphan (#308)
  • Add AmbiguityKind.SEGMENTATION, reported when a surname split had a vocabulary-supported alternative: "남궁민수" is 남궁 + 민수 by the compound surname but 남 + 궁민수 by the single-syllable one, and longest-match had to pick. A name with only one possible split decided nothing and reports nothing (#271)
  • Add the Japanese locale pack locales.JA and the segmenter factory locales.ja_segmenter(), which together divide an unspaced Japanese name: parser_for(locales.JA, segmenter=locales.ja_segmenter()) reads 山田太郎 as family 山田, given 太郎. The two halves are separate because no surname list can do this job — family and given names draw on the same kanji and the reading, not the spelling, decides most divisions — so the pack activates the stage and a third-party divider performs it. ja_segmenter() wraps namedivider-python, installed with the new nameparser[ja] extra; the core stays dependency-free, and ja_segmenter(gbdt=True) selects namedivider's more accurate gradient-boosted model, which downloads its data on first use. With both packs registered, locales.available() is now ('ja', 'ru', 'tr_az', 'zh') (closes #272)
  • Add Segmentation and the Segmenter type alias to the public API, plus the keyword-only Parser(segmenter=...) hook they describe: any callable from a token's text to a Segmentation (the interior offsets to cut at, and a confidence) or None to decline. It is consulted only for scripts listed in Policy.segment_scripts, and only where the surname vocabulary declined first, so parser_for(locales.ZH, locales.JA, segmenter=...) composes — a listed Chinese surname wins, the segmenter takes the rest. Read that composition with the zh pack's own warning still attached: vocabulary-first means a Japanese kanji name opening on a listed Chinese surname never reaches the segmenter, so 高橋一郎 still splits 高 + 橋一郎 under the stack exactly as it does under locales.ZH alone. The two packs are alternatives, one per corpus; stack them only for genuinely mixed data that accepts that trade (#272)
  • Add the Script members HIRAGANA and KATAKANA. Two members rather than one KANA because the parser treats them differently: hiragana never transcribes a foreign name, while a wholly-katakana name usually is one (#272)

  Breaking Changes

  • Change the pickle compatibility of the 2.0 API's Policy and Lexicon: the new fields change the field layout their guarded __setstate__ checks, so a pickle written by 2.0.0 raises ValueError naming the missing fields instead of loading. Re-pickle after upgrading. HumanName pickles are unaffected — the facade pickles v1-shaped component state, not these objects
  • Change the pickle compatibility of Parser in the same way and for the same reason: the new segmenter field changes the layout its guarded __setstate__ checks, so a Parser pickled by 2.0.x raises ValueError naming the missing field rather than loading silently with the field absent. That guard is the design, not a regression — re-pickle after upgrading. A Parser carrying a segmenter pickles only if that segmenter does, which a module-level function does and a closure or lambda does not (#272)
  • Change one thing about parse totality: parse() still never raises on any input, but a user-supplied Parser(segmenter=...) runs inside the parse and its own exceptions propagate rather than being absorbed. A failure there is a bug in your callable, not a fact about the name, and hiding it would only make it harder to find (#272)

  Behavior Changes

  • Fix names written wholly in Han or Hangul parsing given-first: native-script CJK now reads family-first by default, through the new Policy.script_orders table, so "毛 泽东" gives family 毛 where 1.x gave family 泽东. A name that is a single unspaced token moves the same way — "毛泽东" and "山田太郎" now land in family/last where 1.x put them in given/first, with the string itself untouched, which makes it the easiest form of this change to miss — a lone token renders the same whichever field holds it, whereas the spaced form does show up in the output (str(HumanName("毛 泽东")) is now "泽东 毛"). No language detection is involved: Chinese and Japanese both write the family name first in native script, so the script settles the order without anyone having to know which language it is. Latin-script and mixed-script names are never affected, and an explicit comma still wins. Default-on: changes parse output for wholly-CJK names, through HumanName as well as the 2.0 API (closes #271)
  • Fix unspaced Korean names not splitting: the census surname list now ships as default vocabulary (Lexicon.surnames) with hangul segmentation on by default (Policy.segment_scripts), so "김민준" parses family 김, given 민준 where 1.x returned the whole string as first. Rendering follows the split, so str(HumanName("김민준")) is now "민준 김" where 1.x echoed the input back unchanged. Nothing but Korean is written in hangul and its surnames are a closed census set, which is what makes the split safe as a default rather than a pack. Default-on, and it reaches HumanName too. Policy(segment_scripts=()) turns the split off; Policy(script_orders={}) separately restores the positional reading; clearing both restores 2.0 behavior exactly (#271)
  • Fix Japanese names carrying kana parsing given-first: the family-first rule above extends to any name whose characters stay within kanji and kana while carrying at least one kana character, so "高橋 みなみ" gives family 高橋 and "山田 エミ" family 山田 where 1.x read both the other way round, and a lone such token ("高橋みなみ", "みなみ") lands in family/last where 1.x put it in given/first. The reasoning is the one hangul already uses: hiragana never transcribes a foreign name, and a transcription is kana ALONE, so kanji-plus-kana is a Japanese person's name written in Japanese order. A name written wholly in katakana is deliberately excluded and stays positional — it is predominantly a transcribed foreign name ("マイケル ジャクソン") already in given-first order. Default-on: changes parse output for kana-bearing Japanese names, through HumanName as well as the 2.0 API, and the spaced forms change what the name renders as (str(HumanName("高橋 みなみ")) is now "みなみ 高橋"). Policy(script_orders={}) clears this entry along with the Han and Hangul ones (#272)
  • Fix names containing 〆 (U+3006, the shime mark that opens Japanese surnames like 〆木 and 〆谷) parsing given-first: the script classifier now counts 〆 as Han, extending the 々 entry the table already carries, and going a step further than it — 々 is Script=Han and merely outside the ideograph blocks, while 〆 is Script=Common — so these names take the East Asian family-first reading like any other wholly-Han name. Policy(script_orders={}) restores the positional reading for these names exactly as for other wholly-Han names (#303)
  • Fix the katakana middle dot ・ (U+30FB, and its halfwidth twin U+FF65) being read as part of a name rather than as the divider it is: it now separates tokens exactly as a space does. A transcribed foreign name therefore divides into its parts and, being wholly katakana, keeps its source order — "マイケル・ジャクソン" gives given マイケル, family ジャクソン, where 1.x left the whole string in first — while a kanji pair written the same way takes the family-first rule ("高橋・一郎" → family 高橋). Native Japanese names never contain this character and no other script's names use it, so the separation is unconditional, which also means it is not covered by the two policy opt-outs. Rendering follows, the way the Korean split's does: the dot comes back as a space, so str(HumanName("マイケル・ジャクソン")) is now "マイケル ジャクソン", and that reaches delimited content too — the nickname in "山田 太郎 (マイケル・ジャクソン)" renders "マイケル ジャクソン". The Chinese interpunct · is not an unconditional separator like these two: U+00B7 is also the Catalan punt volat and appears inside legitimate names (Gal·la), so it divides only between classified-script characters — the transcription treatment it marks is #298's (#272)
  • Fix 间隔号-divided transcriptions parsing as one unsplit token: U+00B7 — the interpunct Chinese text divides a transcribed foreign name with, 威廉·莎士比亚 for William Shakespeare — is now a token separator between characters of a classified script, and a name it divides keeps its source order and is never segmented: the dot is the transcription marker, playing the role pure katakana plays in the kana license. It divides ONLY between classified-script characters, so the Catalan punt volat interior to names like Gal·la is untouched. The Japanese nakaguro is deliberately not a transcription marker — 高橋・一郎 is roster formatting, 姓・名, and keeps its family-first reading — so a transcription typed with the wrong dot (威廉・莎士比亚) reads by the convention of the codepoint it was typed with; like the spaced form, only the Chinese dot rescues it. Rendering stays space-joined (str(HumanName("威廉·莎士比亚")) is "威廉 莎士比亚"); a custom string_format such as "{first}·{last}" reinstates the dot (#298)
  • Fix spaced CJK postnominal honorifics parsing as name parts: 씨, 박사, 선생님, 교수님, 군, 양 (Korean — standardly written as their own token), 先生, 女士, 小姐, 博士, 教授 (Chinese, with 先生/博士/教授 shared with Japanese), and 様, 氏 (Japanese) now route to suffix, so 王小明 先生 reads family 王小明 where the family-first default had confidently made 先生 the given name. Whole-token matching, which also reaches a glued surname+honorific token, since segmentation splits off the surname first (김씨 reads family 김, suffix 씨). The glued forms whole-token matching cannot reach are handled by the peel described below (closes #307)
  • Fix glued CJK honorifics parsing as part of the name: an honorific written against the name — 田中さん, 山田太郎様, 김민준씨, 김민준님, 王小明先生 — is now split off the end of the last name token and routed to suffix, where it had been swallowed by the name (the whole of 田中さん was the family name; 김민준씨 gave given 민준씨). The peeled name then goes through the ordinary machinery, so the Korean split still happens (김민준씨 → family 김, given 민준, suffix 씨) and the 田中さん case stops misreading as a kana-licensed composite. Only entries that can never END a name peel — 씨, 님, 박사, 박사님, 선생님, 교수님, さん, さま, くん, ちゃん, 様, 先生, 教授, 女士, 小姐 — while 양, 군, 氏, 博士 and 殿 are recognized in their spaced form only, because 김지양 is a given name, 田中博士 is Tanaka Hiroshi as readily as Doctor Tanaka, and some ninety Japanese surnames end in 殿 (鵜殿, 真殿); 君 is recognized in neither form, since 王君 is a complete Chinese name, though its kana spelling くん peels. Seven entries are new vocabulary in this change (さん, さま, くん, ちゃん, 殿, 님, 박사님), so their spaced forms route to suffix too (田中 さん, 田中 殿, 김민준 님, 김민준 박사님). 박사님 closes a gap in the shipped set rather than opening new ground: 선생님 and 교수님 shipped in 2.1 without it, so 김민준박사님 stranded 박사 in the given name and the spaced 김민준 박사님 came back as two suffixes for one honorific. Exactly one honorific peels off a token, and every entry is a whole honorific rather than a part of one. A token that is nothing but an honorific is no longer taken apart either — 선생님 and 박사 now stay whole where hangul segmentation had split them 선 + 생님 and 박 + 사, since 선 and 박 are listed surnames — which is default-on in its own right, hangul segmentation being a default. A configured segmenter benefits twice over: it is handed the name without the honorific, and the honorific the peel just cut off does not then look to it like a boundary the writer drew — so parser_for(locales.JA, segmenter=ja_segmenter()) reads 山田太郎様 as family 山田, given 太郎, suffix 様. Worth knowing before you upgrade: that exemption is what makes a GLUED honorific stop protecting a name from division, so a family name written alone with one — 田中さん — now divides the way bare 田中 already did (family 田, given 中, suffix さん). It is exactly and only the peeled tail that is exempt. A SPACED honorific is a token boundary its writer typed, and anything standing beside a name calls the segmenter off, so the name is left as written: 田中 さん and 佐藤 氏 keep family 田中 and 佐藤 under the pack — the division the pack gives them without this change, whichever field the honorific itself lands in. That is the conservative reading rather than a claim about intent: a spaced honorific cannot be told apart from a spaced given name by position, and counting it as one keeps four real surnames whole (佐藤 氏, 田中 様, 鈴木 先生, 中村 教授) at the price of the one division it then declines to make (山田太郎 様). Writing the honorific spaced is therefore an opt-out in its own right on the SEGMENTER path, alongside declining the pack or the segmenter. It is no lever where the VOCABULARY divides the name, the two spellings agreeing exactly there — 김민준 씨 and 김민준씨 both give family 김, given 민준, suffix 씨, as do 王小明 先生 and 王小明先生 under the Chinese pack — and Korean data has no pack to decline either, hangul segmentation being on by default. Default-on: changes parse output for glued CJK honorific forms, through HumanName as well as the 2.0 API (closes #308)
  • Fix NFD-decomposed input missing the East Asian defaults entirely: script classification now normalizes to NFC before deciding, so a Korean or Japanese name typed on macOS — where decomposed text is routine — gets the same order rule as its composed twin, which it silently did not before. Segmentation MATCHING deliberately stays raw, so an unspaced NFD hangul name is ordered correctly but not split, rather than being split in the wrong place. One gotcha worth stating plainly: parse output preserves the encoding it was given, so for NFD input name.family == "김" is False even though it is the same name — compare NFC-normalized text when comparing across encodings (#272)
  • Fix the Ukrainian conjunction й not joining the pieces around it: it is the euphonic alternate of і, the two chosen by the surrounding vowel and consonant rather than by meaning ("Олесь і Олена" but "Марія й Петро"), so real Ukrainian data carries both spellings and shipping only і recognized just one of them. "Олесь й Олена Коваленки" now gives given "Олесь й Олена" where the й previously landed in middle. Same treatment as the и/і entries added in 2.0.0, single-letter carve-out included: the conjunction joins only once the name has enough pieces, and a punctuated initial still wins, so "Й. Сліпий" is unaffected. Raised in a comment on #267

• 2.0.0 - July 27, 2026

  Two release candidates preceded this release (rc1 on 2026-07-23, rc2 on 2026-07-26). Please report anything the migration missed on issue #284. The notes below describe 2.0.0 as a whole.

  nameparser 2.0 adds a new parsing API alongside HumanName. parse() returns an immutable ParsedName whose seven fields are named for what they are (given, family) rather than where they sit in a Western name, configured by two frozen value objects -- a Lexicon of vocabulary and a Policy of behavior -- instead of a mutable global. HumanName keeps working: it is now a compatibility facade over the same pipeline, and it stays through 2.x. The removals below are the deprecations announced in 1.3.0 and 1.4.0 coming due; if your code runs warning-free on 1.4.0, most of them will not affect you. See :doc:`migrate` for the field-by-field map.

  The 2.0 API

  • Add parse(text), returning an immutable ParsedName with seven fields -- title, given, middle, family, suffix, nickname, maiden -- plus the derived views given_names, surnames, family_base and family_particles. Parsing is a pure function of the text, a Lexicon and a Policy: nothing global is consulted and nothing is mutated
  • Add Lexicon, the frozen vocabulary object. Lexicon.default() is the shipped vocabulary and Lexicon.empty() is a blank one; add(**entries), remove(**entries) and field-wise | all return new instances. Its fields are titles, given_name_titles, suffix_acronyms, suffix_words, suffix_acronyms_ambiguous, particles, particles_ambiguous, conjunctions, bound_given_names, maiden_markers and capitalization_exceptions
  • Add Policy, the frozen behavior object: name_order, patronymic_rules, middle_as_family, nickname_delimiters, maiden_delimiters, extra_suffix_delimiters, lenient_comma_suffixes, strip_emoji and strip_bidi
  • Add Parser, a reusable parser bound to a lexicon and policy (Parser(lexicon=..., policy=...).parse(text)), and parser_for(*locales, base=None), which folds locale packs onto a base parser
  • Add name_order and the constants GIVEN_FIRST, FAMILY_FIRST and FAMILY_FIRST_GIVEN_LAST, so a family-first name can be parsed as written rather than reordered by hand (the configuration half of #270; the locale packs below complete it)
  • Add PatronymicRule with the members EAST_SLAVIC and TURKIC. v1's single patronymic_name_order flag enabled both detectors at once; Policy(patronymic_rules=...) lets you enable either one alone
  • Add PolicyPatch and the UNSET sentinel for partial policy deltas that compose -- set-valued fields union, scalar fields override with later winning. This is the mechanism locale packs are built from, and UNSET is only needed when you must distinguish "not set" from a real False or None
  • Add Token, Span and Role: every field is backed by tokens carrying exact (start, end) offsets into the original string, reachable with tokens_for(Role.GIVEN). This replaces v1's *_list attributes and makes it possible to highlight or re-slice the input the parse came from. Role is a StrEnum, so members compare and stringify as their field names (Role.GIVEN == "given"), matching AmbiguityKind; tokens_for() accepts a role's string name too, and raises ValueError for an unknown role
  • Add STABLE_TAGS to the public API: the four documented Token.tags values (particle, conjunction, initial, joined)
  • Add Policy.patched(patch), applying a PolicyPatch directly without wrapping it in a locale pack
  • Add Parser.matches(a, b) and Parser.capitalized(name): the ParsedName methods of the same names fall back to the default configuration for str/omitted arguments, which is silently wrong for names parsed with a custom Parser
  • Add Parser.revise(name, **fields): ParsedName.replace() with the replacement text classified by the parser's vocabulary, so particle/initial/suffix-join behavior survives the edit
  • Add Ambiguity and the AmbiguityKind enum, so a parse reports what it had to guess at instead of guessing silently. The kinds emitted today are particle-or-given, suffix-or-name, suffix-or-nickname, unbalanced-delimiter and comma-structure; order is reserved and not yet emitted. The two suffix kinds cover the post-nominals that are also ordinary words: "John Smith MA" reports that MA was read as a credential rather than a surname, and "JEFFREY (JD) BRICKEN" that the delimited JD was read as a nickname rather than a suffix. A reading the vocabulary settles on its own — "John Smith M.A.", "Andrew Perkins (MBA)" — is not a guess and reports nothing
  • Add ParsedName output and comparison methods: render(spec), initials(), capitalized() (which returns a new value rather than mutating in place), as_dict() (whose include_empty flag is keyword-only, unlike HumanName.as_dict()'s), replace(**fields), matches() and comparison_key()
  • Add Locale, the public pack type. Writing your own needs no registration -- construct a Locale and pass it to parser_for()
  • Ship a fully typed public API (PEP 561): the core modules are checked under strict mypy settings, and nameparser 2.0 has no runtime dependencies

  Breaking Changes

  • Raise the minimum Python to 3.11 and drop the last runtime dependency, typing_extensions (#257). Python 3.10 is no longer supported
  • Remove HumanName.__eq__ and __hash__ (deprecated in 1.3.0, #223): instances now compare and hash by identity, so HumanName("John Smith") == "John Smith" is False where 1.x returned True. This changes result silently rather than raising -- it is the one removal that can pass unnoticed into production. Use matches() to ask whether two names are the same, and comparison_key() as a dict key or sort key
  • Remove every v1 parsing hook and subclass extension point: pre_process, post_process, parse_pieces, parse_nicknames, join_on_conjunctions, the is_* predicates, cap_word/cap_piece, handle_firstnames, fix_phd and the rest. A subclass that overrides one gets a DeprecationWarning at construction naming the hooks, because the facade delegates to the core Parser and never calls them (closes #280). Customize through Lexicon/Policy instead
  • Remove regex configuration: CONSTANTS.regexes is now a read-only proxy. Reads still work, but CONSTANTS.regexes.bidi = False, item assignment and Constants(regexes=...) all raise TypeError. If you followed 1.3.1's advice to keep bidi marks with CONSTANTS.regexes.bidi = False, that opt-out is now Policy(strip_bidi=False) on the 2.0 API; the same applies to regexes.emoji and Policy(strip_emoji=False)
  • Remove bytes input and the encoding argument (#245): passing bytes to HumanName or to a set manager raises TypeError with a decode hint, and SetManager.add_with_encoding() and DEFAULT_ENCODING are gone. Decode first, then use add()
  • Remove SetManager.__call__ (#243); iterate the manager or call set(manager). remove() of a missing member now raises KeyError like set.remove -- discard() is the ignore-missing form -- and the set operators |, &, - and ^ return a plain set
  • Remove HumanName slice access and item assignment (#258): name[1:-3] and name['first'] = value raise TypeError. String-key reads (name['first']) and iteration are unchanged; assign fields as plain attributes
  • Remove Constants.empty_attribute_default (#255): empty fields are always ''. Assigning it raises AttributeError; a pickle carrying the key still loads, with the value ignored
  • Remove constants=None (#261): both HumanName(..., constants=None) and hn.C = None raise TypeError. Use Constants() for library defaults or CONSTANTS.copy() for a private snapshot
  • Remove silent unknown-key access on the mapping managers (#256): CONSTANTS.capitalization_exceptions.typo and CONSTANTS.regexes.typo raise AttributeError naming the miss, instead of returning None/EMPTY_REGEX (capitalization_exceptions also lists the known keys). .get() remains available on both for intentional soft access
  • Remove support for Constants pickles written by nameparser 1.2.x or earlier (#279): loading one raises ValueError telling you to re-pickle under 1.3/1.4 first
  • Remove the dead regexes.no_vowels pattern (#268) and the Constants.suffixes_prefixes_titles cached union; neither was read by the parser
  • Change HumanName's *_list attributes to read-only properties: they remain readable snapshots, but name.first_list = [...] now raises AttributeError
  • Change the Constants constructor to keyword-only; positional construction no longer works

  Behavior Changes

  • Recognize maiden-name markers -- née, nee, geb., roz. and the Scandinavian participle forms -- and route the following name to the new maiden field. 1.x folded them into middle/last, so "Jane Smith née Jones" parsed as middle="Smith née" (closes #274)
  • Recognize typographic nickname delimiters by default in both APIs (closes #273): smart quotes (“Jack”), German and Polish low-high quotes („Hansi“), Swedish right-right quotes (”Ann”), guillemets in either direction («Petit», »Hansi«), CJK corner brackets (「タロ」, 『ハナ』) and fullwidth parentheses. In 1.x these leaked into middle as literal text. Curly single quotes stay excluded, because U+2019 is the apostrophe in "O’Connor"
  • Fix the pre-comma piece being routed to first when everything after the comma is a suffix or title: "Andrews, M.D." now reads family Andrews / suffix M.D. where 1.x read given M.D. / family Andrews, and "Smith, Dr." moves Smith from first to family (the title was already correct in 1.x). The piece before a comma is definitionally the family name
  • Fix a lone recognized trailing suffix with no comma being routed to first/last: "Johnson PhD" and "Mr. Johnson PhD" now keep the suffix in suffix
  • Fix a split "Ph. D." credential being read as two tokens; it now classifies as one suffix, replacing v1's fix_phd hook. This now holds wherever the credential sits: 1.x healed the pair only when it trailed, so "Ph. D. John Smith" parsed as title Ph. / given D. with the real given name pushed to middle; it now reads given John, family Smith, suffix Ph. D.
  • Fix chargé d'affaires: shipped as one unmatchable TITLES entry since it was added, it is now two chainable entries (chargé, d'affaires), so the title is recognized; the unaccented spelling charge ships too, like attaché/attache
  • Remove seven multi-word SUFFIX_ACRONYMS entries (leed ap, nicet i–nicet iv, psm i, psm ii) that could never match in any release; splitting them would swallow real names ("John Leed", "Smith, A.P."), so they are dropped instead
  • Add a UserWarning when a multi-word entry is stored in a per-word Lexicon field or as a capitalization_exceptions key -- such entries can never match
  • Parse an input with no alphanumeric character to an empty name in both APIs. 1.x kept pure punctuation as a name part, so "." gave first="." and bool() was True; 2.0 empties it, keeping bool(parse(x)) an honest "did I get a name?" test. The check is Unicode-aware, so names in any script are unaffected; only inputs that are entirely punctuation or symbols (".", "- -") change. Junk embedded in a name with real content -- the stray dot in "John . Smith" -- is still kept, since that parse is already truthy
  • Fold a leading never-given particle into the family name. Note that Lexicon.particles_ambiguous is the complement of v1's non_first_name_prefixes, not a rename -- it lists the particles that may double as a given name, where v1 listed the ones that may not. Copying a v1 customization across without inverting it silently reverses the behavior; see :doc:`migrate`
  • Add ma and do to suffix_acronyms_ambiguous, the set of post-nominals that are also ordinary surnames. An entry there is read as a credential when the name can spare it — written with periods ("John Smith M.A."), or when removing it still leaves a given and a family name ("John Smith MA" → suffix MA). With only two pieces to go around, the surname reading wins instead: "Jack Ma" and "Anh Do" keep their family names. As a side effect, a parenthesized or quoted "(MA)"/"(DO)" now falls through to nickname parsing rather than escaping to suffix, since inside delimiters the nickname reading is the plausible one
  • Change comparison_key() and matches() in both APIs to fold with str.casefold() where 1.4 used str.lower(), so Unicode case pairs compare equal -- "STRASSE" matches "Straße", and a Greek final sigma matches its regular form. This is strictly more permissive: anything 1.4 matched still matches. Vocabulary normalization deliberately still uses lower(), for v1 parity
  • Change the 2.0 API's default render()/str() spec to show every non-empty field: '{title} {given} "{nickname}" {middle} {family} ({maiden}) {suffix}'. The quoted nickname round-trips exactly; the parenthesized maiden re-parses as a nickname, a deliberate choice of presentation over lossless round-trip -- use née {maiden} in a custom spec if you need it to survive a reparse. HumanName keeps v1's own string_format default, unchanged
  • Change delimiter-overlap precedence in the 2.0 API: a pair listed in Policy.maiden_delimiters is dropped from the effective nickname set, so Policy(maiden_delimiters={("(", ")")}) alone routes parenthesized content to maiden. The default nickname set is exported as DEFAULT_NICKNAME_DELIMITERS. HumanName keeps v1's nickname-wins precedence, so no existing behavior changes
  • Change suffix-delimiter rendering when a custom suffix delimiter is configured: for suffix_delimiter="/" and "John Smith, RN/CRNA", 1.x split the token and rendered suffix="RN, CRNA" where 2.0 keeps it whole as "RN/CRNA". Role assignment is unchanged; only rendering differs
  • Correct a long-standing typo in the shipped vocabulary that 1.x carried: actor and television had trailing spaces in TITLES, so "actor" in TITLES was False. Parse output is unchanged -- the parser normalizes entries on ingest, which is exactly what let the typo go unnoticed -- but code that tests membership against the exported constants directly will see corrected results. The data modules now assert their invariants at import time, alongside the ones prefixes.py already checked; entries must be stored lowercase and whitespace-free, so this class of typo now fails the build

  International name support

  • Add nameparser.locales with the first two packs: locales.RU (East Slavic patronymic order) and locales.TR_AZ (Turkic patronymic markers). Packs are pure data folded in at parser_for(locales.RU), they compose (parser_for(locales.RU, locales.TR_AZ) unions the rules), and they are never auto-detected -- there is no reliable way to detect a name's language from the name alone. locales.available() and locales.get(code) look packs up by code; loading is lazy, so importing the package imports no pack (completes #270; #271/#272/#146 stay staged for 2.x)
  • Add non-Latin vocabulary to the default lexicon (#269): Cyrillic, Greek, Arabic and Hebrew titles, conjunctions and name particles. Native-script entries cannot collide with Latin-script names, which is what makes them safe to enable by default. Deferred pending vetting: the Cyrillic мл/ст suffixes and the bare Greek κ title, which collides with the initial-plus-surname shape. Behavior note: محمد بن سلمان now chains بن onto the family name where 1.x read it as a middle name
  • Add Arabic-script bound given names (#269): عبد, the kunya pair أبو/ابو, and أم/ام join the following word into the given name exactly as their transliterations (abdul, abu, umm) always did, so عبد الرحمن محمد parses given عبد الرحمن, family محمد where 1.x split it into given plus middle
  • Add Arabic honorific titles and the conjunction و (#269): the doctor, professor, hajj, sheikha and engineer forms (الدكتور/الدكتورة/دكتور/دكتورة, الأستاذ/الأستاذة/أستاذ/أستاذة, الحاج/الحاجة, الشيخة, مهندس) as given-name titles, since Arabic honorifics precede the given name like الشيخ. Deferred under the collision rule: bare سيد/شيخ/أمير/سلطان (all common given names), the د. abbreviation (bare د would swallow initials), and the Ottoman post-nominals باشا/بك/أفندي (which survive as family names)
  • Add Hebrew honorifics and post-nominals, and Devanagari titles (#269): the Israeli honorifics גברת, פרופ'/פרופ׳, פרופסור, עו"ד/עו״ד and הרב as titles; ז"ל/ז״ל and שליט"א/שליט״א as suffixes, in both gershayim spellings; and Devanagari श्री, श्रीमती and डॉ. Latin sri/shri were deliberately not added, because they collide with real given names where the native script cannot. Deferred: bare רב (an ordinary word meaning "many") and בר as a particle (Bar is a common modern given name)

  Compatibility layer

  • Reimplement HumanName as a facade over the 2.0 pipeline, and Constants as a shim resolving to a (Lexicon, Policy) snapshot with a shared parser cache. Fields, aggregates, mutation through name.C.titles.add(...), rendering defaults, capitalize(), matches(), comparison_key(), iteration, as_dict() and pickling are all preserved, and nameparser.parser and nameparser.config remain importable. The compatibility layer ships through 2.x and is removed in 3.0
  • Note that CONSTANTS.capitalize_name and force_mixed_case_capitalization are still honored through the facade, but the 2.0 API never capitalizes during parse() -- call capitalized() when you want it
  • Add Role members (and their string values given/family) as valid HumanName subscript keys: hn[Role.GIVEN] returns hn.first
  • Add a UserWarning when assigning HumanName.given or .family: the facade spells those attributes first/last, so the assignment creates an inert stray attribute while the parse keeps the old value. The assignment still happens (v1-legal ad-hoc attributes keep working); the warning names the v1 spelling to use

  Command line

  • Rewrite python -m nameparser over the 2.0 API with a real argument parser. It prints the parse plus its capitalized form and initials by default, takes --json to emit the fields as JSON (python -m nameparser --json "Doe, John"), takes --locale CODE to apply a pack, and exits with a usage message on bad arguments

  Documentation

  • Rewrite the documentation new-API-first: a new front page and README, usage.rst as a tour of the 2.0 API, a principle-first customize.rst, a reference split into the 2.0 API and the compatibility layer, and new pages for :doc:`concepts`, :doc:`locales` and :doc:`migrate` -- the last carrying full attribute and configuration maps from v1 names to 2.0 names (#262). The 1.x documentation remains online as the readthedocs stable build

  Parsing changes were checked against a 652-name differential corpus -- names harvested from the v1 test banks, plus names reported in the issue tracker -- and everything not listed above parses identically between 1.4.0 and 2.0. The harness lives in tools/differential/ in the source repository (it is development tooling, not part of the installed package) -- see its README to reproduce the comparison against your own names.

  Changed since 2.0.0rc1 (for anyone who tested the release candidate)

  • Role became a StrEnum; str(Role.GIVEN) is now "given"
  • ParsedName.tokens_for() raises ValueError for unknown roles instead of returning no tokens; it also accepts role-name strings
  • ParsedName.as_dict()'s include_empty is keyword-only
  • HumanName subscripting accepts Role members
  • Assigning HumanName.given/.family warns (the facade spells them first/last; the assignment was and remains an inert stray attribute)
  • The eight multi-word vocabulary entries that could never match were repaired (chargé d'affaires split; seven credential acronyms removed), and storing a new multi-word entry now warns; those eight are dropped silently, not warned about, when a restored Constants pickle carries all eight of them (the pre-2.0 signature)
  • PolicyPatch's repr shows only the fields a patch sets, instead of all nine with UNSET sentinels
  • New since rc1: STABLE_TAGS, Policy.patched(), Parser.matches(), Parser.capitalized(), and Parser.revise() -- see the API section above

• 1.4.0 - July 12, 2026

  • Add Constants.copy(), a detached deep copy that preserves the source instance's current customizations (unlike Constants(), which always starts from library defaults) -- useful as CONSTANTS.copy() for a private snapshot of the shared config (#260)
  • Deprecate passing constants=None to HumanName (or assigning hn.C = None): it silently builds a fresh Constants(), discarding any customizations the caller may have expected to carry over from the shared CONSTANTS. Emits DeprecationWarning; will raise TypeError in 2.0. Use constants=Constants() for fresh library defaults or constants=CONSTANTS.copy() for a private snapshot instead (closes #260)
  • Deprecate assigning Constants.empty_attribute_default for removal in 2.0 (#255): once None support goes, the only legal value left is the default '', so a dial with one position isn't configuration. Emits DeprecationWarning; reading the attribute is unaffected
  • Deprecate unknown-key attribute access on TupleManager/RegexTupleManager (CONSTANTS.regexes.typo, CONSTANTS.capitalization_exceptions.typo, etc.) for removal in 2.0 (#256): a misspelled or omitted key currently degrades silently (None/EMPTY_REGEX) with no traceback pointing at the typo. Emits DeprecationWarning naming the miss and the known keys; will raise AttributeError in 2.0. .get() remains available for intentional soft access
  • Deprecate HumanName slice access (name[1:-3]) and item assignment (name['first'] = value) for removal in 2.0 (#258): field access by position has no real use case, and item assignment duplicates plain attribute assignment. Both emit DeprecationWarning; string-key access (name['first']) is unaffected
  • Deprecate SetManager.add_with_encoding() itself for removal in 2.0 (#245), regardless of argument type: use add() instead (decoding bytes first). Previously only the bytes path warned; the str path was silent even though the whole method goes away
  • Deprecate loading a legacy-format Constants pickle (written by nameparser <= 1.2.x, before the 1.3.0 pickle fix) for removal in 2.0 (#279): __setstate__'s migration shim currently skips the stale computed-property key silently. Emits DeprecationWarning once per call telling users to re-pickle; will raise ValueError in 2.0
  • Fix the "Lastname, Firstname" comma format not being recognized when the input uses the Arabic comma ، (U+060C, the standard comma in Arabic/Persian/Urdu text) or the fullwidth CJK comma ， (U+FF0C) instead of the ASCII comma: both variants now also split the format and no longer leak into the parsed output (closes #265)

• 1.3.1 - July 11, 2026

  • Fix invisible Unicode bidirectional control characters (LRM/RLM/ALM, the embedding/override marks, and the isolates U+2066–U+2069) surviving parsing and sticking to first/last/etc., so a copy-pasted right-to-left name silently failed equality and dedup. They are now stripped in preprocessing like emoji; disable via CONSTANTS.regexes.bidi = False (closes #266)
  • Fix str() corrupting name text containing the substring "None" when empty_attribute_default is None (e.g. "Nonez Smith" rendered as "z Smith"): empty attributes are now substituted as '' before the format string is applied, instead of scrubbing the interpolated "None" from the output afterward (closes #254)

• 1.3.0 - July 5, 2026

  Breaking Changes & Deprecations

  • Deprecate HumanName.__eq__ and __hash__ for removal in 2.0 (#223): the current design's three promises — case-insensitive equality, equality with plain strings, and hashability — are mutually inconsistent (equal objects can hash differently), equality depends on string_format, and maiden is invisible to it. Both now emit DeprecationWarning naming the replacement; behavior is otherwise unchanged until 2.0 (closes #224)
  • Deprecate bytes input for removal in 2.0 (#245): passing bytes to HumanName/full_name or to SetManager.add()/add_with_encoding() now emits DeprecationWarning — decode first, e.g. value.decode('utf-8'). The encoding constructor argument is deprecated with it
  • Deprecate SetManager.__call__ for removal in 2.0 (#243): calling a manager returns the raw underlying set, so mutating the result bypasses normalization and cache invalidation; iterate the manager or copy with set(manager) instead
  • Add SetManager.discard(), and deprecate remove() of a missing member (#243): it currently does nothing but will raise KeyError in 2.0, matching set.remove; use discard() for intentional ignore-missing removal. Removing present members is unchanged and does not warn
  • Fix HumanName acting as its own iterator with a stored cursor: breaking out of a loop, iterating in nested loops, or calling len(name) mid-loop corrupted subsequent iteration; iter(name) now returns a fresh independent iterator each time. next(name) on the instance itself (undocumented) now raises TypeError — call next(iter(name)) instead (closes #225)
  • Remove the vestigial unparsable attribute: the guard that was meant to set it has been unreachable since 2013 (v0.2.9), so it has reported False for every parsed name for over a decade; check len(name) == 0 to detect an empty parse
  • Remove __ne__; Python 3 derives != from __eq__ automatically
  • Change internal initials helper __process_initial__ to _process_initial: double-underscore-both-sides names are reserved for Python special methods; subclasses overriding the old name must rename their override
  • Change REGEXES from a set of (name, pattern) tuples to a dict, so a duplicate name is a visible overwrite in the source instead of a nondeterministic winner at import time; code iterating REGEXES directly now gets keys instead of pairs — use .items() (#227)
  • Change CAPITALIZATION_EXCEPTIONS from a tuple of (key, value) tuples to a dict; code iterating it directly now gets keys instead of pairs — use .items() (#233)

  Behavior Changes (affect existing parse output)

  • Add bound_first_names set to Constants; bound Arabic given-name prefixes (abdul, abu, etc.) now join forward to form a single first name (e.g. "abdul salam ahmed salem" → first="abdul salam", middle="ahmed", last="salem"). Disable via CONSTANTS.bound_first_names.clear(). Default-on: changes parsing output for names with these prefixes. (#150)
  • Treat an unrecognized, multi-letter token ending in a period in the leading title run (before the first name is set), e.g. "Major.", as a title instead of a first name; internal-period abbreviations ("E.T.") and single-letter initials ("J.") are unaffected. Default-on: changes parsing of names with a leading unknown period-abbreviation (closes #109)
  • Fix parsing writing back into the Constants it reads (usually the shared module-level CONSTANTS): pieces derived while parsing a name — period-joined titles/suffixes like "Lt.Gov." and conjunction-joined pieces like "Mr. and Mrs." or "von und zu" — are now tracked per parse instead of being permanently add()-ed to the config, so parse results no longer depend on which names were parsed earlier in the process and parsing no longer mutates shared state across threads
  • Fix __hash__ to lowercase the name like __eq__ does, so equal HumanName instances hash equal and behave correctly in sets and dicts

  New comparison methods

  • Add matches() and comparison_key() for explicit name comparison: matches() compares parsed components case-insensitively (parsing str arguments first, so name.matches("Smith, John") and name.matches("John Smith") both match) and comparison_key() returns a hashable tuple of the seven components for dedup, dict keys, and sorting (#224)

  New name fields

  • Add a first-class maiden field and maiden_delimiters to Constants, so a delimiter (e.g. parenthesis) can be routed to maiden instead of nickname for alternate/maiden surnames, e.g. "Baker (Johnson), Jenny" (closes #22)
  • Add given_names (and given_names_list) attribute as aggregate of first and middle names, mirroring surnames (closes #157)
  • Add last_base, last_prefixes (and _list variants) for splitting last-name prefix particles (tussenvoegsels) from the core surname (#130, #132)

  New customization options

  • Add initials_separator to Constants and HumanName to control spacing between consecutive initials within a name group (#171)
  • Add suffix_delimiter to Constants and HumanName for parsing suffixes separated by arbitrary delimiters, e.g. "RN - CRNA" (#156)
  • Add nickname_delimiters to Constants for registering additional nickname-delimiter regex patterns at runtime, without subclassing (closes #110, #112)
  • Add suffix_acronyms_ambiguous to Constants for acronym suffixes that also read as given-name nicknames (e.g. "JD", "Ed"), used when disambiguating parenthesized/quoted content (#111)

  International name support

  • Add patronymic_name_order flag to Constants and HumanName for opt-in detection and reordering of Russian formal-order names (Surname GivenName Patronymic) (#85)
  • Add Turkic (Azerbaijani/Central-Asian) patronymic detection to patronymic_name_order, rotating the reversed 4-token formal shape (Surname GivenName PatronymicRoot Marker, e.g. oglu/qizi) into Western order (#185)
  • Add middle_name_as_last flag to Constants and HumanName for opt-in folding of middle names into the last name, for naming systems with no middle-name concept (e.g. Arabic patronymic chaining) (#133)
  • Add non_first_name_prefixes to Constants: a leading particle that is never a first name (e.g. "de Mesnil", "dos Santos") now parses as a surname with an empty first name, instead of treating the particle as the first name (closes #121)
  • Add international honorifics to TITLES (#187)
  • Add German/Austrian nobility and ecclesiastical titles to TITLES (closes #101)
  • Add German/Dutch last-name prefixes and title/degree suffixes; fix join_on_conjunctions() to register multi-word prefix chains (e.g. "von und zu") as prefixes, mirroring existing title handling (closes #18)

  Parsing fixes

  • Fix suffix boundary lookup for prefixed last names with a title before and after (e.g. "dr Vincent van Gogh dr" producing a corrupted middle name) (closes #100)
  • Fix a repeated prefix word in a prefix chain (e.g. "Juan de la de la Vega") silently dropping the earlier occurrence in join_on_conjunctions(): value-based pieces.index(prefix) lookups re-found the wrong occurrence once the list had already been mutated by prior joins; prefix positions are now tracked positionally instead of re-derived by value (closes #208)
  • Fix a trailing suffix being silently dropped after an empty comma segment, e.g. "Doe, John,, Jr." losing the "Jr."
  • Fix degenerate comma input (a bare "," or an empty comma segment, e.g. "Doe,, Jr.", "John Doe, Jr.,,") leaving an empty-string member in first_list, last_list, or suffix_list; whitespace-only tokens assigned via the setters are dropped the same way
  • Fix suffix-shaped parenthesized/quoted content (e.g. "(Ret)", "(MBA)") being misclassified as a nickname instead of a suffix (closes #111)
  • Fix single-character symbol conjunctions (e.g. "&", "/") being ignored in short names (#173)
  • Fix recognition of single-letter roman numeral suffixes (e.g. "I", "V") in suffix-comma format (closes #136)
  • Fix recognition of trailing suffix_not_acronyms (e.g. "Jr.") in lastname-comma format (closes #144)
  • Fix missing comma between 'msc' and 'mscmsm' in suffix_acronyms, which silently concatenated them into a bogus 'mscmscmsm' entry (#111)
  • Fix 'apn aprn' split into separate suffix_acronyms entries so each is recognized independently (closes #155)

  Formatting and output fixes

  • Fix IndexError in initials()/initials_list() when a *_list attribute was assigned directly with an element containing unnormalized whitespace (e.g. name.middle_list = ['Q R']), bypassing the parser's whitespace normalization (closes #232)
  • Fix initials() emitting a stray empty initial (e.g. "J. . V.") -- or raising TypeError when empty_attribute_default is None -- for name parts with no initialable words, e.g. a prefix-only middle name like "de la"
  • Fix capitalization of suffix acronyms written with dots, e.g. "M.D." (closes #141)
  • Fix extra whitespace before punctuation in str() output when a string_format field is empty (closes #139)
  • Fix spurious leading space in surnames and empty token in suffix list after capitalize() with an empty middle or suffix (#164)

  API correctness and cleanup

  • Fix the five non-cached-union SetManager-backed Constants attributes (first_name_titles, conjunctions, bound_first_names, non_first_name_prefixes, suffix_acronyms_ambiguous) accepting non-SetManager assignment silently (e.g. constants.conjunctions = 'and'), degrading membership checks into substring tests with no error; assignment now raises TypeError like the four cached-union attributes already did (closes #241)
  • Fix HumanName.C accepting an invalid constants value on post-construction assignment (e.g. hn.C = 'garbage'), bypassing the constructor's validation and failing later with an unrelated AttributeError; C is now a property that validates on assignment too (closes #239)
  • Fix TupleManager (and RegexTupleManager) accepting a bare string/bytes argument (raising a cryptic dict-internals ValueError) or an iterable of 2-character strings (silently shredding each into a key/value pair, e.g. Constants(capitalization_exceptions=['ii']) becoming {'i': 'i'}); both now raise TypeError with a clear message (closes #242)
  • Fix SetManager.__contains__ being the one operation that didn't normalize (lowercase, strip leading/trailing periods) its operand, so e.g. 'Dr.' in constants.titles could return False even though the title was correctly configured; membership checks now normalize like add()/remove()/the constructor/the set operators (closes #244)
  • Fix a bare string passed to a set-backed Constants argument (e.g. Constants(titles='dr')), to SetManager, or as a SetManager set-operator operand (e.g. constants.titles |= 'esq') being silently split into single characters, replacing or polluting the set and producing wrong parses with no error; it now raises TypeError with the suggested fix — wrap strings in a list, decode bytes first (closes #238)
  • Fix SetManager set operators and the constructor skipping the lowercase/strip-edge-periods normalization that add() applies: constants.titles |= ['Esq.'] kept a raw 'Esq.' the parser's lookups could never match, titles & ['Dr.'] missed 'dr', and Constants(titles=[...]) stored raw elements that silently never matched; elements and operands are now normalized everywhere, and non-str elements (bytes, None, numbers) raise TypeError instead of crashing cryptically or being coerced
  • Fix the constants constructor argument silently discarding Constants subclass instances: the exact-type check replaced them with fresh defaults, throwing away the caller's configuration. Subclass instances are now used as given; anything that is neither None nor a Constants instance now raises TypeError instead of being silently swapped for defaults (closes #226)
  • Fix Constants customizations, singleton identity, and TupleManager subclass being lost across pickle/deepcopy round-trips (#167, #168, #169)
  • Fix is_rootname() returning stale results after add()/remove() on titles, prefixes, suffix_acronyms, or suffix_not_acronyms (#166)
  • Fix the library logger calling setLevel(logging.ERROR) on import, which silently discarded log records regardless of an application's own logging configuration; the logger now leaves its level at NOTSET and lets the application control verbosity (closes #228)
  • Minor internal cleanups: drop a dead length check in the initials helper, simplify double-wrapped len(list(...)) calls, and other small parser tidy-ups with no behavior change (closes #229)
  • Change Constants.__repr__ to report collection sizes and non-default scalar config, replacing the uninformative <Constants() instance> (#221)

• 1.2.1 - June 19, 2026
