+### Note ###
+
+Due to regression in the 2.3.0 release that was fixed by [#13464](https://github.com/angular/angular/pull/13464),
+components that have been compiled using 2.3.0 and published to npm will need to be recompiled and republished.
+
+The >=2.3.1 compiler will issue is the following error if it encounters components compiled with 2.3.0:
+`Unsupported metadata version 2 for module ${module}. This module should be compiled with a newer version of ngc`.
+
+We are adding more tests to our test suite to catch these kinds of problems before we cut a release.

-## The `PR: merge` label and `presubmit-*` branches
+# Change approvals
 
-We have automated the process for merging pull requests into master. Our goal is to minimize the disruption for
-Angular committers and also prevent breakages on master.
+Change approvals in our monorepo are managed via [pullapprove.com](https://about.pullapprove.com/) and are configured via the `.pullapprove.yaml` file.
 
-When a PR has `pr_state: LGTM` and is ready to merge, you should add the `pr_action: merge` label.
-Currently (late 2015), we need to ensure that each PR will cleanly merge into the Google-internal version control,
-so the caretaker reviews the changes manually.
 
-After this review, the caretaker adds `zomg_admin: do_merge` which is restricted to admins only. 
-A robot running as [mary-poppins](https://github.com/mary-poppins)
-is notified that the label was added by an authorized person,
-and will create a new branch in the angular project, using the convention `presubmit-{username}-pr-{number}`.
+# Merging
 
-(Note: if the automation fails, committers can instead push the commits to a branch following this naming scheme.)
+Once a change has all the approvals either the last approver or the PR author (if PR author has the project collaborator status) should mark the PR with "PR: merge" label.
+This signals to the caretaker that the PR should be merged.
 
-When a Travis build succeeds for a presubmit branch named following the convention,
-Travis will re-base the commits, merge to master, and close the PR automatically.
+# Who is the Caretaker?
 
-Finally, after merge `mary-poppins` removes the presubmit branch.

-The list of users who can trigger a merge by adding the `zomg_admin: do_merge` label is stored in our appengine app datastore.
