[v3.0.0] - 2026-04-13

Added

• Add GitHub Actions workflow to automatically build and deploy API documentation to GitHub Pages
• Add bandit and vulture to .pre-commit-config.yaml for security and dead-code checks on every commit
• Add pre-commit hooks
• Add ruff linter and formatter to pre-commit hooks (#117)
• args.py: expand HELP_TEXTS with standard help texts for all common parameters (always-ok, critical, warning, insecure, no-proxy, timeout, url, ignore-regex, match, lengthy, count, test, etc.)
• disk.py: add get_owner()
• lftest.py: add run() function for declarative, data-driven unit tests using subTest()
• nextcloud.py: new library
• txt.py: add exception2text()
• winrm.py: add WINRM_CONFIGURATION_NAME option to run_ps()
• winrm.py: execute ps in run_ps() directly without Invoke-Expression wrapping

Changed

• base.py: get_perfdata() now sanitizes labels by stripping single quotes and replacing = with _
• base.py: get_perfdata() output no longer has trailing semicolons
• base.py: get_table(): document why pure ASCII delimiters are used instead of Unicode box-drawing characters
• base.py: get_worst() now accepts any number of state arguments (*states). Existing two-argument callers keep working unchanged, but plugins that need to combine three or more states in one call no longer have to nest the call - e.g. get_worst(state, used_state, committed_state) instead of get_worst(state, get_worst(used_state, committed_state))
• base.py: deduplicate get_state() operator logic using operator module
• base.py: deduplicate sum_dict() by delegating to sum_lod()
• base.py: improve get_table() performance for large tables
• base.py: move parse_range() and state name mapping to module level
• base.py: remove unused collections import
• db_sqlite.py: reduce unnecessary dictionary object creation
• human.py: deduplicate bits2human()/bps2human()/bytes2human() via shared _to_human() helper
• human.py: deduplicate humanrange2bytes()/humanrange2seconds() via shared _convert_range() helper
• human.py: pre-compute mappings as module constants
• lftest.py: test() now accepts args with fewer than three elements. Plugins can be invoked as --test=path/to/fixture without the trailing ,,0; stderr defaults to the empty string and the return code to 0
• powershell.py: run_ps() now always returns a dict
• Remove pre-built documentation from the repository (now auto-deployed via GitHub Actions)
• txt.py: improve filter_mltext() performance (avoid O(n²) string concatenation)
• txt.py: improve readability of extract_str() fallback logic
• txt.py: remove unused Python 2 type aliases and outdated comments
• txt.py: simplify to_text() and to_bytes() for Python 3 only (remove dead Python 2 codepaths)
• winrm.py: make run_cmd() and run_ps() JEA-aware
• winrm.py: make run_cmd() and run_ps() Kerberos-aware

Removed

• Drop support for Python older than 3.9. The lib now requires Python 3.9 or newer; this matches the oldest still-supported enterprise Linux (RHEL 8) and lets the codebase use modern syntax and standard-library features

Fixed

• base.py: cu() now also escapes HTML characters in the error message, not just in the traceback
• base.py: cu() now detects active exceptions via sys.exc_info() instead of string-matching the traceback
• base.py: get_state() no longer calls sys.exit() on malformed range specs, returns UNKNOWN instead

... (truncated)

• b504bef chore: bump version number [skip ci]
• ac64af7 fix(lftest): accept --test args with fewer than three elements
• 930351a feat(lftest): add run_container() helper for testcontainers-python
• b5acfa2 refactor(base): get_worst() accepts variadic states
• b530b1a fix: semantic bugs found in the LLM audit backlog
• d803b57 fix: sweep lib for ruff F/B findings and bandit low/medium annotations
• dbfc375 Merge pull request #119 from Linuxfabrik/dependabot/github_actions/dependabot...
• 78f2434 chore(deps): bump dependabot/fetch-metadata from 2 to 3
• ccb252f fix(args): remove "Supports Nagios ranges" from HELP_TEXTS (not all plugins i...
• f784119 fix(args): add case-insensitive note to --ignore-pattern HELP_TEXT
