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becomes megalinter_linter_run_*, plus new run-level megalinter_run_* series), and the old docs/grafana dashboards are superseded.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):

• Breaking changes

• Core

• New linters

  • biome, one fast toolchain linting, formatting and sorting imports of JavaScript, TypeScript, JSX, TSX, JSON, CSS and GraphQL files, available as JAVASCRIPT_BIOME, TYPESCRIPT_BIOME, JSX_BIOME, TSX_BIOME, JSON_BIOME, CSS_BIOME and GRAPHQL_BIOME
    • Activated only when a biome.json or biome.jsonc configuration file is found in the repository
    • Supports APPLY_FIXES (safe fixes with --write) and native SARIF output
    • EXCLUDED_DIRECTORIES are forwarded in project lint mode through a generated configuration extending the workspace one

• Disabled linters

• Re-enabled linters

• Deprecated linters

• Removed linters

• Media

• Linters enhancements

• Fixes

• Reporters

• Flavors

• Doc

  • New Docker pulls per month graph, showing the growth of MegaLinter adoption since October 2020, displayed in the README and on the Flavors statistics page
  • Refreshed the MegaLinter references in linters documentation (linter_megalinter_ref_url): verified all existing links, updated moved pages (ktlint, robocop, csharpier, zizmor, ruff, proselint), and opened 47 suggestion PRs on linters repositories that did not mention MegaLinter yet

• mega-linter-runner

  • Node.js 22 or higher is now required (was 20)
  • 8 npm dependencies removed (chalk, fs-extra, which, uuid, find-package-json, simple-git, mem-fs, assert), replaced by Node.js built-in modules: faster npx mega-linter-runner startup and a smaller supply-chain attack surface
  • Fixed mega-linter-runner --version displaying error instead of the version when the npm_package_version environment variable is not set

• Agent Skills

  • megalinter-check now handles the commit MegaLinter pushes itself when the repository uses APPLY_FIXES_MODE: commit
    • CI providers ignore pushes made with the CI token, so the branch used to stay stuck on the stale checks of the run that produced the fixes

[UNRELEASED]

No user facing changes.

4.37.6 - 04 Aug 2026

• Changed the default filepath for the new remote file address format that was introduced in CodeQL Action 4.37.0 / 3.37.0 to .github/codeql-config.yml to align it with the suggested path that is used elsewhere. #4070

4.37.5 - 03 Aug 2026

• Fixed a bug where a network error while streaming the download of the CodeQL bundle could terminate the init Action instead of falling back to downloading the bundle before extracting it. #4061

4.37.4 - 29 Jul 2026

• This version of the CodeQL Action adds support for the tools input for the codeql-action/init step to be specified using a github-codeql-tools repository property. This feature will gradually be rolled out following the release of this version. Once rolled out, this allows for the CodeQL CLI version that is used in GitHub-managed workflows, such as Default Setup, to be set to a custom value. For example, customers who run into issues with rate limits when a new CodeQL CLI version is released can set the value to toolcache to always use the CodeQL CLI version that is available in the runner toolcache. For Advanced Setup workflows, the value provided for tools in the workflow definition always takes precedence unless the value of the repository property starts with !. #4037
• Update default CodeQL bundle version to 2.26.2. #4051

4.37.3 - 22 Jul 2026

No user facing changes.

4.37.2 - 21 Jul 2026

• The new address format for the config-file input that was introduced in CodeQL Action 4.37.0 is now enabled by default. In addition to the format described there, the remote= prefix can now be used to explicitly indicate that the input refers to a remote file. All previous input formats continue to be accepted as well. #4023
• The CodeQL Action can now make use of configured private registries in Default Setup to retrieve CodeQL configuration files from remote repositories that require authentication. This will allow customers to store their CodeQL configuration in a single repository that can then be referenced by Default Setup workflows in other repositories. We expect to roll this and other, related changes out to everyone in July. #4007

4.37.1 - 16 Jul 2026

• Upcoming breaking change: Add a deprecation warning for customers using CodeQL version 2.20.6 and earlier. These versions of CodeQL were discontinued on 1 July 2026 alongside GitHub Enterprise Server 3.16, and will be unsupported by the next minor release of the CodeQL Action. #3956
• Update default CodeQL bundle version to 2.26.1. #4019

4.37.0 - 08 Jul 2026

• Update default CodeQL bundle version to 2.26.0. #3995
• In addition to the existing input format, the config-file input for the codeql-action/init step will soon support a new [owner/]repo[@ref][:path] format. All components except the repository name are optional. If omitted, owner defaults to the same owner as the repository the analysis is running for, ref to main, and path to .github/codeql-action.yaml. Support for this format ships in this version of the CodeQL Action, but will only be enabled over the coming weeks. #3973

4.36.3 - 01 Jul 2026

No user facing changes.

4.36.2 - 04 Jun 2026

• Cache CodeQL CLI version information across Actions steps. #3943
• Reduce requests while waiting for analysis processing by using exponential backoff when polling SARIF processing status. #3937
• Update default CodeQL bundle version to 2.25.6. #3948
