# Upgrading to FirebaseUI 6.0

**Note**: FirebaseUI versions `6.0.0` and `6.0.1` contain critical issues. Please use version
`6.0.2` or later.

FirebaseUI version `6.0.0` has no breaking API changes from version `5.1.0` but updates
critical dependencies to new major versions.

There are two major groups of changes:

 * Convert all Android Support Library dependencies to AndroidX or Jetpack dependencies. For
   information on migrating to AndroidX see [this guide][androidx-migrate].
 * Update all Firebase and Google Play services dependencies to their latest major versions. For
   information on changes included in these SDKs visit the [release notes][firebase-relnotes].
