0.11.9 — 2026-01-05

Changed

• Upgrade pdfminer.six from 20251107 to 20251230. (75bbed3 + 1524ce4 + 26687c3 + 9555532)

[0.11.8] - 2025-11-08

Added

• Add edge_min_length_prefilter table setting for initial edge filtering. Lowering this setting enables capturing small edge segments (e.g., dashed lines) that would be filtered out with the default minimum length of 1. Raising this setting would be less common but plausible. (h/t @​bronislav). (#1274).

Changed

• Upgrade pdfminer.six from 20250506 to 20251107 (h/t @​henry-renner-v). (0079187)

[0.11.7] - 2025-06-12

Added

• Add access to Page.trimbox, Page.bleedbox, and Page.artbox (h/t @​samuelbradshaw). (#1313 + 7e364e6)

Changed

• Upgrade pdfminer.six from 20250327 to 20250506. (4c7e092)

Removed

• Remove stroking_pattern and non_stroking_pattern object attributes, due to changes in pdfminer.six. (4c7e092)

[0.11.6] - 2025-03-27

Changed

• Upgrade pdfminer.six from 20231228 to 20250327 (3fcb493 + 12a73a2)
• Use csv.QUOTE_MINIMAL for .to_csv(...) (980494a)

Fixed

• Fix bug with use_text_flow=True text extraction (h/t @​samuelbradshaw)(#1279 + e15ed98)
• Catch exceptions from pdfminer and malformed PDFs (43ccc5b)
• More broadly handle RecursionError (748ff31)

Removed

• Remove test_issue_1089 (#1263 + 7e28e76)

[0.11.5] - 2025-01-01

Added

• Add --format text options to CLI (in addition to previously-available csv and json) (h/t @​brandonrobertz). (#1235)
• Add raise_unicode_errors: bool parameter to pdfplumber.open() to allow bypassing UnicodeDecodeErrors in annotation-parsing and generate warnings instead (h/t @​stolarczyk). (#1195)
• Add name property to image objects (h/t @​djr2015). (#1201)

Fixed

• Fix PageImage.debug_tablefinder(...) so that its main keyword argument is named the same (table_settings=) as other related Page methods (h/t @​n-traore). (#1237)

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
