v10.0.0

What's Changed

• Breaking changes

  • Removed 14 deprecated or long-disabled linters, and the API, MAKEFILE and PUPPET descriptors, which had no other linter left. MegaLinter does not provide Makefile and Puppet linting anymore. See the new Removed linters page for the full list and suggested replacements. (#8606)
  • REPOSITORY_GITLEAKS has been removed: migrate to REPOSITORY_BETTERLEAKS, which reads your existing .gitleaks.toml and .gitleaksignore files unchanged. (#8606)
  • Existing .mega-linter.yml files keep working: configuration variables of removed linters are simply ignored (a single notice lists any found in your configuration) and remain valid in the JSON schema. (#8606)
  • API Reporter payload v2 replaces the v1 payload: metric series are renamed (linter_run_* becomes megalinter_linter_run_*, plus new run-level megalinter_run_* series), and the old docs/grafana dashboards are superseded. Re-provision the new dashboards with npx mega-linter-runner --upload-dashboards grafana — see the migration notes. Legacy NOTIF_API_* variables remain supported as aliases. (#8661)
  • Linters now time out after 5 minutes by default (LINTER_TIMEOUT_SECONDS: 300): a linter exceeding it is killed and reported as an error (exit code 124) instead of running (or hanging) unbounded. If some of your linters legitimately run longer, raise the limit globally with LINTER_TIMEOUT_SECONDS, per linter with <LINTER_KEY>_TIMEOUT_SECONDS, or restore the previous unbounded behavior with value 0. (#8665)

• Core

  • Coding agents integration: MegaLinter can now be driven by Claude Code, Cursor CLI, GitHub Copilot CLI, Codex and many other coding agents — see the new Coding Agents documentation page (#8614)
    • Install the MegaLinter agent skills with npx skills add oxsecurity/megalinter
    • Then ask your agent to set up MegaLinter (megalinter-setup), watch CI or local runs (megalinter-check) or fix lint errors (megalinter-fix)
    • Before the first local run, the skills now make sure the user is aware that MegaLinter is Docker-based and needs a good computer configuration and internet connection (the image download can weigh several GB), and suggest watching CI results instead when that is a problem
    • Local runs launched by the skills now cap PARALLEL_PROCESS_NUMBER to 4 on local computers (CI runs keep one parallel linter process per CPU core), so linting does not saturate the machine
    • Local runs launched by the skills now always activate the JSON reporter (not generated by default) to read results reliably, and fall back to the report folder configuration then the console output instead of waiting for report files that a repository configuration may have disabled
  • Excluded directories are now forwarded to project-mode linters, massively speeding up local runs, fixes #8645
    • Linters that scan the whole workspace by themselves (REPOSITORY_TRIVY, REPOSITORY_CHECKOV, REPOSITORY_GRYPE, REPOSITORY_TRUFFLEHOG, REPOSITORY_SEMGREP and 50+ others) used to crawl everything, including build caches and node_modules: a seconds-long CI lint could take hours on a local checkout
    • MegaLinter now automatically passes the excluded directories (defaults, EXCLUDED_DIRECTORIES, ADDITIONAL_EXCLUDED_DIRECTORIES, and directories detected in FILTER_REGEX_EXCLUDE) to each of these linters, through its native exclusion flags or a generated ignore/config file
    • Every forwarded exclusion is logged in the linter's console section, and the ">300 gitignored files" performance warning now names the heaviest directories it found
    • Opt out globally with FORWARD_EXCLUDED_DIRECTORIES: false, or per linter with <LINTER_KEY>_FORWARD_EXCLUDED_DIRECTORIES: false
  • Default excluded directories now also include common build/cache folders: .wireit, .turbo, .nx, .yarn/cache, .pnpm-store, .parcel-cache, .angular, and the Salesforce CLI .sf / .sfdx state folders (#8646)
  • New per-linter timeout: a linter still running after 5 minutes (LINTER_TIMEOUT_SECONDS: 300 by default) is killed along with all its child processes and reported as an error (exit code 124) with an actionable message, while the other linters keep running. Raise the limit globally with LINTER_TIMEOUT_SECONDS, per linter with <LINTER_KEY>_TIMEOUT_SECONDS, or disable it with value 0 (#8665)
  • New prerun analysis mode (mega-linter-runner --prerun, or MEGALINTER_PRERUN=true environment variable): MegaLinter identifies active linters and collects files, then stops before running any linter and suggests configuration improvements, in the console and in megalinter-reports/prerun-report.json (#8653)
    • Suggested exclusions: top-level directories containing only gitignored files (safe: linting scope is unchanged, and project-mode linters stop scanning them), and well-known generated/vendored folder names (site, dist, vendor...) still containing lintable files (to confirm by the user)
    • A lighter matching flavor is also suggested when available
    • The megalinter-check agent skill uses it on the first local run to tune .mega-linter.yml with the user before the real lint
    • Fixed a performance issue where detecting .gitignored files enumerated every individual file inside large ignored folders (node_modules, build output...) instead of stopping at the folder boundary, which could make the file collection step (including prerun) take several minutes on big repositories
  • Much lighter Docker images: the main image download shrinks by 9%, flavors by 9% to 22%, and standalone megalinter-only-* images are 35% to 65% smaller (#8621)

    • If your PRE_COMMANDS compile native code: the compilation toolchain is no longer shipped in the images, install it back with apk add --no-cache gcc make musl-dev

    • Main and flavor images, compressed download size on ghcr.io, linux/amd64 (before = v9.6.0, so deltas also include the linters removed in this version):

Notices

⚠️ Your configuration references items that have been removed from MegaLinter and are ignored: REPOSITORY_GITLEAKS. See Removed linters to find their replacements.

See detailed reports in MegaLinter artifacts

Your project could benefit from a custom flavor, which would allow you to run only the linters you need, and thus improve runtime performances. (Skip this info by defining FLAVOR_SUGGESTIONS: false)
