+# Different change workflows in Gerrit
+
+In Release 2.3 (2012) draft changes and draft patch set workflow
+was added to Gerrit. This implementation extended change status with
+DRAFT value. DRAFT status in change occurs before NEW and will be for
+a change that is not meant for review (yet). Draft changes and draft
+patch sets can be removed or published. Publishing a draft patchset in
+a draft change irreversibly upgrades the change status to NEW. In addition
+draft changes implied visibility restriction: only change owners and
+reviewers can see drafts.
+
+In 2013 OpenStack project proposed alternative Work In Progress workflow,
+that was not adopted in gerrit core at that time. Later, based on his work,
+work in progress plugin was created. This plugins had some limitation because
+it wasn't a core feature, like set-Ready, set-WIP events were not fired or
+suppressing mail notifications for WIP changes wasn't implemented.
+
+In 2017, during migration of Chromium project from Rietveld to Gerrit the WIP
+workflow got another momentum, as it was a hard requirement for Chromium project
+migration to Gerrit.
+
+In 2.15 Work In Progress workflow was added to Gerrit core and Draft changes
+workflow was discontinued.
+
+In this talk we will compare different workflows and possible alternatives and
+clarify the migration path from older Gerrit versions that may still have
+draft changes and draft patch sets. We will also look at possible improvements
+of new WIP workflow.
