What's Changed

Take 2 mn to read MegaLinter v9.5.0 announcements

• Breaking changes

  • Docker images published only to GitHub Container Registry (ghcr.io) until OIDC-based publishing to Docker Hub is implemented. The Docker Hub registry (docker.io/oxsecurity/megalinter) is frozen at v9.4.0: pulls of oxsecurity/megalinter:v9 (or :beta, or any flavor tag) will keep returning v9.4.0. To get v9.5.0 and later from CI tools other than GitHub Actions (GitLab CI, Azure Pipelines, Bitbucket, Jenkins, Drone, raw docker run, …), switch your image references:

    • oxsecurity/megalinter:v9 → ghcr.io/oxsecurity/megalinter:v9
    • oxsecurity/megalinter:beta → ghcr.io/oxsecurity/megalinter:beta
    • oxsecurity/megalinter-<flavor>:v9 → ghcr.io/oxsecurity/megalinter-<flavor>:v9

    GitHub Action users (uses: oxsecurity/megalinter@v9) and mega-linter-runner users are not affected, as both already pull from ghcr.io.

  • ESLint-based linters upgraded to v10+. Legacy .eslintrc.* configs are no longer supported: you must migrate to flat-config (eslint.config.js) to keep using JAVASCRIPT_ES, TYPESCRIPT_ES, JSX_ESLINT, TSX_ESLINT, and JSON_ESLINT_PLUGIN_JSONC.

  • Airbnb and Standard ESLint configs replaced (they never shipped ESLint 9+ support):

    • extends: ["airbnb"] → extends: ["airbnb-extended"]
    • extends: ["standard"] → extends: ["neostandard"]

• Core

  • User notifications system: linters can surface structured "Notices" to end users in the PR comment / report footer (used for ESLint migration, deprecated options, etc.), replaces the ad-hoc migration warnings
  • Security: more default hidden environment variables, so a compromised linter cannot leak your secrets
  • Upgrade .NET runtime to 10.0 (csharpier, dotnet-format, roslynator, devskim, tsqllint, vbdotnet-format)
  • Upgrade GO runtime to 1.26.3

• New linters

  • osv-scanner: trivy-like vulnerability scanner by Google
  • zizmor: GitHub Actions static analysis

• Disabled linters

  • KICS (until upstream security issue is fixed)
  • Spectral (crashing)

• Re-enabled linters

  • Trivy (v0.70.0): the supply chain security incident is resolved

• Deprecated linters

• Removed linters

• Media

• Linters enhancements

  • ESLint: legacy .eslintrc.* configs are now detected and a migration notice is emitted in the report so users know they need to switch to flat-config
  • shellcheck: honour the BASH_SHELLCHECK_CONFIG_FILE variable / .shellcheckrc config file
  • raku (Rakudo): now ships on ARM64 too
  • scala: linter installation is now deterministic (same binary across rebuilds)
  • v8r (JSON/YAML schema validation): output now shows only validation errors (no more "no schema found" or success noise)
  • lychee: removed the deprecated exclude_mail option (no longer supported by lychee upstream)
  • Faster image pulls: several linters (Lua/StyLua arm64, clj-kondo, kubescape, ls-lint, dotenv-linter) now use pre-built Alpine binaries instead of compiling from source

• Fixes

... (truncated)
