**//PolyGerrit Plugins//**
* code-mirror-editor for the inline editor experence.
* image-diff for diffing images (does not support svg for security reasons).
* zuul-status for incorporating the zuul status interface into your patch.
//**Other**//
* Projects have gained secondary index.
* Everything has been migrated to NoteDB (Groups, and some minor tables) (Possibly resolving T176532 by doing cross dc (since we won't be loading anything sensitive through ReviewDB!))
* Git protocol 2 support has been added. (disabled by default due to private changes being exposed, we can enable this as we disabled the private change feature).
* and many many many more changes and improvements.
**Plugins**
