 # Release from workstation
 
+⚠ Update `product-descriptor` in <./graph-database-support-plugin/src/main/resources/META-INF/plugin.xml>
+  - `release-version ` It is different from the version of the plugin, as this one is a version number of the major release (== release which happened on release-date). You shouldn't put a minor release version here to make sure that perpetual fallback license holders get access to minor updates of the major version.
+  - See [Rules](https://plugins.jetbrains.com/docs/marketplace/prepare-a-plugin-to-be-sold-via-the-marketplace.html) and  [Notes on the paid plugins versioning](https://plugins.jetbrains.com/docs/marketplace/notes-on-the-paid-plugins-versioning.html)
