+title: Release schedule and version policies
+permalink: pmd_about_release_policies.html
+author: Andreas Dangel <andreas.dangel@pmd-code.org>
+last_updated: June 2024 (PMD 7.3.0)
+---
+
+## Release schedule
+
+PMD uses a time-based release schedule.
+
+We release a new minor version **every month**, usually on the last Friday of the month.
+A patch release will only be done if necessary (e.g. blocker bugs).
+
+## Version policy
+
+PMD aims to follow [SemVer](https://semver.org/), that means, versions are numbered in the form MAJOR.MINOR.PATCH.
+
+A **major** release can break any compatibility, and it means more effort to upgrade to the next major version (like
+it was from 6.x to 7.x, see [Migration Guide for PMD 7](pmd_userdocs_migrating_to_pmd7.html).
+
+A **minor** release tries to be compatible so that an effortless (aka "drop-in replacement") upgrade is possible
+with some exceptions.
+
+Such releases might contain:
+
+* fixed false-positive (FP) issues for rules
+* fixed false-negative (FN) issues for rules: These fixes might break your builds, as new violations might be found.
+* new rules: these new rules are not used by default _if_ you use custom rulesets, so they shouldn't affect your builds.
+* deprecations of existing functionality
+
+In summary: we only guarantee stability on how you integrate / use the tool, but builds may start failing because
+we fixed FNs, or introduced a new rule (ie: for people referencing whole categories).
+We stick to our current approach when moving / renaming rules of deprecating them, and referencing
+the new one until the next major.
+
+A **patch** release absolutely is a drop-in replacement. So only bugs (ie: crashes or obviously broken stuff,
+like rules not being applied at all), or security issues (dependency updates, hardening, etc.) are part of
+a patch release.
+
+See also
+
+* [ADR 3 - API evolution principles](pmd_projectdocs_decisions_adr_3.html)
+* [Rule deprecation policy](pmd_devdocs_rule_deprecation_policy.html)
+
+## Git branches/tags policy
+
+* Main development happens on the main branch (currently called `master`).
+* PR and enhancements are done on the main branch.
+* Release are usually done directly from the main branch, we don't create release branches.
+* Each release has its own tag named `pmd_releases/MAJOR.MINOR.PATCH`.
+* In case of a patch release, we either do it from the main branch (if there was no development ongoing)
+  or create a separate branch off the last release tag.
+* See also [Release process](pmd_projectdocs_committers_releasing.html).

+
+In general, only the latest major version is in active development and regularly will receive new features
+and bug fixes etc.
+Once a new version is released, the previous version becomes unsupported.
+We recommend to always update to the latest version to benefit from new features and bug fixes.
