  • If there are more than 500 .gitignored files, advise to add more excluded directories using variable ADDITIONAL_EXCLUDED_DIRECTORIES, to improve performances
  • Reduce redundant config lookups, environment copies, and dict rebuilds across config, linter, and utils modules
  • Cache subprocess environment per linter run and excluded directories per request
  • Optimize parallel linter result update from O(n²) to O(n)
  • Add support in the build of Docker images for linux/arm64 in compatible linters

• New linters

  • Add PYTHON_NBQA_MYPY for type-checking Jupyter notebooks using nbqa + mypy

• Disabled linters

  • LUA_SELENE: Kampfkarren/selene#662

• Linters enhancements

  • Use the official checkmake image by @​bdovaz
  • Spectral: Add sarif support to spectral by @​bdovaz
  • Spectral: Change cli_lint_mode to list_of_files to improve performances

• Fixes

  • Add support for SSH remote origins when building custom flavors (fixes: #6511)
  • Fix issue with plugins ignored when FLAVOR_SUGGESTIONS=false
  • Fix wrong tagging apply_fixes=True when linter has no fix options configured
  • Python mypy: Remove .ipynb from file extensions (mypy doesn't support notebooks directly) - fixes #6904
  • Fix operator precedence bug in pre_post_factory pre/post command logic
  • Fix file handle leak in GitleaksLinter
  • Fix variable name bug in utils.get_git_context_info

• Reporters

  • Add a link inviting to star MegaLinter
  • Display in the console reporter the working directory from which the commands are executed by @​bdovaz
  • Update WebHook reporter so it can send more events for a better integration with UI
  • When truncating long comments in markdown reports, keep the end of the text instead of the beginning (which usually contains less useful information)
  • In case GitHub Api returns 500, do not make the whole MegaLinter fail, display a warning instead
  • Azure Reporter: Use Azure DevOps Services REST API instead of unmaintained python wrapper lib

• Flavors

  • Custom flavor builder:
    • Add support for SSH remotes
    • Allow selection of platforms to build the custom flavor on (ex: linux/amd64, linux/arm64) and build compatible linters on these platforms
    • Build & release custom flavor builder image for linux/arm64

• Doc

  • JSON Schema: Add default values for file extensions and file names variables + improve descriptions
