This isn't just a yearly release, there are major enhancements that your projects will benefit from for sure :)
plz like & share LinkedIn post 🙏
Main enhancements
- 🤖 Coding agents integration: drive MegaLinter from Claude Code, Cursor, GitHub Copilot CLI, Codex and many more: install the agent skills with
npx skills add oxsecurity/megalinter/skills, then ask your agent to "setup megalinter" (documentation)
- ⚡ Much faster runs: excluded directories are now forwarded to project-mode linters (hours → minutes on local checkouts), faster startup, parallelized fixers, and a new
--prerun analysis mode that suggests configuration improvements
- 🐳 Much lighter Docker images: main image -9%, flavors up to -22%, standalone
megalinter-only-* images up to -65% smaller
- 📊 Observability: feed your MegaLinter results into Grafana, Datadog, Elastic or New Relic, with ready-to-use linked dashboards provisioned by
npx mega-linter-runner --upload-dashboards <provider> (documentation)
- ⏱️ Per-linter timeout (5 minutes by default): a hanging linter no longer blocks the whole run
- 🧹 Breaking: 14 deprecated or long-disabled linters removed (notably
REPOSITORY_GITLEAKS → use REPOSITORY_BETTERLEAKS) - see Removed linters for the full list and replacements
- ⬆️ 50 linters upgraded
