TiddlyWiki Core Version According to the standard: ``` Given a version number MAJOR.MINOR.PATCH, increment the: MAJOR version when you make incompatible API changes, MINOR version when you add functionality in a backwards-compatible manner, and PATCH version when you make backwards-compatible bug fixes. Additional labels for pre-release and build metadata are available as extensions to the MAJOR.MINOR.PATCH format. ``` !! Alpha and Beta versions While in alpha TiddlyWiki5 uses the pre-release label "alpha", for example: ``` 5.0.1-alpha ``` Each new alpha or beta release will bump the `PATCH` version number. This breaks the strict semantics of versioning because `PATCH` increments are supposed to be reserved for compatible changes. //Note that prior to ''5.0.1-alpha'', TiddlyWiki5 used version numbers formatted as ''5.0.0-alpha.19''. The change was made to enable the upgrade mechanism to recognise plugin updates from the version information.// !! Interim versions During development when a new release is being prepared, the pre-release label is set to `prerelease`. ! Plugin Versions Version numbers TiddlyWiki5 uses the version information attached to plugins for determining which of two plugins is more recent during an upgrade or import. The pre-release label is ignored when performing these comparisons.
