Version 1.3.0

• Python 3.10 support
  • Added 134 rules specific to Python 3.10
  • Structural pattern matching (PEP-0634)
  • Support optional length-checking of zip (PEP-0618)
  • Union types written as X | Y (PEP-0604)
  • Detect mapping attribute of dict views (bpo-40890)
  • Additionally testing and analyzing using Python 3.10 with GitHub Actions
• Optionally exclude parsing comments for 30-40%+ speedup. The --no-parse-comments argument or parse_comments = no config setting, can be used to disable it.
• Not scanning symlinks to folders can incur huge speedups for certain projects, especially if they
  point inside a project's hierarchy. These symlinks can be included in analysis via the --scan-symlink-folders argument or scan_symlink_folders = yes config setting.

Deprecations

• Lax mode has been deprecated in favor of specific analysis exclusions. Will be removed in v. 1.4.

1.1.0:

• Config file support (#56)

Vermin automatically tries to detect a config file, starting in the current working directory where it is run, following parent folders until either the root or project boundary files/folders are reached. However, if --config-file is specified, no config is auto-detected and loaded.

Config file names being looked for: vermin.ini, vermin.conf, .vermin, setup.cfg

Project boundary files/folders: .git, .svn, .hg, .bzr, _darcs, .fslckout

A sample config file can be found here.

• Added new arguments:
  • --no-backport
  • --no-dump
  • --no-exclude
  • --no-feature
  • --no-hidden
  • --no-ignore
  • --no-lax
  • --no-pessimistic
  • --no-quiet
  • --no-target
  • --show-tips to have an opposite of --no-tips
  • --dump long form of -d
• Extended comment exclusion support (#59)
• Added and fixed backports (#61)
• Detect unpacking assignment (3.0)
• Fixed false positive generalized unpacking cases (#63)
• Fixed magic line Python detection
• Incompatible interpretation on syntax errors using --pessimistic (#48)
• Fixed exception cause related minimum versions (#60)
• Fixed reported line of with statement
• Fixed solitary #novermin border case with newline before it
• Added txt as excluded extension for detection
• GitHub Actions fixes
  • Test and analyze on PRs too
  • Finish coveralls session when all parallel tests are done
• Renamed lax mode to lax (internal)
• Extend lax mode support
• Tidy up Makefile
