v0.6.0

Added

• Pipe mode: check-unicode - reads stdin line-by-line and writes to stdout,
  enabling use as a streaming Unix filter for log monitoring, CI pipelines, and
  editor buffer filtering
• --strip [dangerous|all] flag to remove non-ASCII characters; dangerous
  strips only invisible/bidi chars, all (default) strips any remaining
  non-ASCII after allow-list processing
• --halt [dangerous|all] flag to stop immediately on first matching character;
  dangerous (default) halts on invisible/bidi chars, all halts on any
  non-ASCII
• --fix, --strip, and --halt are fully composable and work identically
  across file and pipe modes

Changed

• En dash and em dash now replace to - instead of --
• Expanded --fix replacement table with: hyphen variants (U+2010-2012, U+2015,
  U+FE58), soft hyphen (removed), bullets, dot leaders, arrows (->, <-, ^,
  v), and math operators (x, /)
• Add pytest-sugar for improved test output
• Replace mypy with ty for type checking
• Move dev dependencies from optional-dependencies to dependency-groups
• Switch CI from pip to uv for faster, reproducible installs; check in uv.lock
• Extract codepoint/range parsing into check_unicode.parsing module for reuse
• Codepoint parser now validates the Unicode range (0..U+10FFFF) and rejects
  empty/invalid input with clear error messages
• Range parser now rejects inverted ranges (lo > hi) and tolerates whitespace
  around the dash separator

v0.5.0

Fixed

• Validate severity values from config files and overrides (invalid values
  like "warn" now exit 2 instead of silently behaving as warning)
• Catch config file errors (missing file, invalid TOML) and exit 2 with a
  friendly message instead of a raw traceback
• Validate --allow-category and --allow-script values; unknown names now
  exit 2 with a hint to use --list-categories or --list-scripts
• Warn on unrecognised top-level config keys (e.g. typo alow-codepoints)
• Remove dead U+FFFD entry from REPLACEMENT_TABLE (unreachable because
  U+FFFD is in DANGEROUS_INVISIBLE, which is checked first)
• Exclude tests/fixtures/ from mypy (intentionally malformed Trojan Source
  files)

Added

• Grouped output: findings are now grouped per file with a compact line range
  header (e.g. file.txt:1,4-80,90:), context lines shown once with multi-caret
  markers (^ normal, ! dangerous, ? confusable), deduplicated identical
  context lines, and collapsed codepoint listing with (xN) counts

Changed

• Refactor _apply_replacements to use str.translate() for cleaner code and
  better performance on large files
• Read each file once when --check-confusables is enabled (previously
  check_file and check_confusables each read the file independently)
• Simplify _parse_codepoint to use prefix-stripping instead of fragile
  double-replace chain
• Add slots=True to Override dataclass for consistency with Finding and
  AllowConfig

Docs

• Document per-file [[tool.check-unicode.overrides]] in README and man page
• Update man page version to 0.4.0 and fix stale pre-commit rev
• Add man page to bump-my-version files list

v0.4.0

Added

• [[tool.check-unicode.overrides]] per-file config: apply different
  allow-lists, severity, and confusable settings per file pattern
• Per-file severity: override severity to "warning" for specific file
  patterns so findings don't affect exit code
• Per-file confusable toggle: enable or disable check-confusables per file
  pattern
• uv.lock added to .gitignore

v0.3.3

Fixed

• --fix mode now fixes all files, not just the first (any() short-circuited
  after the first fixable file, skipping the rest)

v0.3.2

Added

• CONTRIBUTING.md guide
• SECURITY.md with private vulnerability reporting instructions
• Issue templates for bug reports and feature requests
• Make bump-my-version handle README.md version

v0.3.1

Added

• PR template with changelog and testing checklist
• Coverage threshold (80%) enforced in CI
• markdownlint config: allow duplicate headings across sibling sections

v0.3.0

Added

• Grouped CLI help with --help showing organized option sections
• Usage examples in --help output
• Man page (docs/check-unicode.1)
• Release workflow for automatic GitHub Releases on tag push
• bump-my-version config for version management
