 # matrix-auth-plugin
 
 Requires `matrix-auth` >= 3.2
-> Starting from version 3.2 of the `matrix-auth` plugin, the JCasC syntax for configuring permissions has changed. The previous `permissions:` format is deprecated and replaced with a structured `entries:` format. While older configurations may still work with `deprecated: warn`, it is recommended to migrate to the new format.

 Some permissions depends on actual plugin-usage.  
 For Example: `Release/*:authenticated` is only available if you _use_ the Release plugin in one of your jobs.
