There has been over 5436 commits since 2.15.
This will be the last 2.x release (10 years after the first commit was produced for making gerrit 2.x)
**Bug fixes / New features**
//**PolyGerrit / GWTUI**//
* **GWTUI** is officially deprecated and will be removed in 3.0 (it has already been removed)
* PolyGerrit has been made the default UI.
* PolyGerrit has a experimental dark theme (can be enabled through settings).
* PolyGerrit supports inline editing.
* PolyGerrit has been redesigned to look modern. (Dashboard, Change Screen, Change List and admin view and more)
* Admin View has gained support for mobile viewing by adding bread crumb navigations.
* PolyGerrit now has a comment thread.
* PolyGerrit now has change status badges. This makes it easier to tell if the change is open, merged, abandoned, merge conflicts, WIP or private.
* PolyGerrit now tells new users how to update their own change and even how to create their first change!
* We can define custom themes in a polygerrit for users to choose from now.
* PolyGerrit now supports project dashboards.
* **//PolyGerrit only plugin//** codemirror-editor. This is included in the build options by default. This is used for PolyGerrit's inline editing experience.
* **//PolyGerrit only plugin//** image-diff. This plugin is for diffing images to be able to tell the slight difference you may not notice when looking at it.
//**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.
* and many many many more changes and improvements.
**Plugins**
* **its-base**: Repo owners can now get GerritBot to add specific comments or projects or rules. You edit refs/meta/config branch of the repo.
** You create a actions-its-phabricator.config file.
