## Changelog Entries for Stable

The entries below will be used when constructing a soft-copy of the
stable release changelog. Leave blank or remove the lines if no entry in
the stable changelog is needed. Entries should be on the same line,
without the `{{` `}}` brackets. You can use multiple lines, even of the
same type. The valid suffixes are:

* NEW-FEATURE: for new, relatively sizable features. Features listed
here will likely have docs / social media posts / marketing launches
associated with them, so use sparingly.
* IMPROVEMENT: for new functionality of existing features.
* BUG-FIX: for fixes related to known bugs or regressions.
* IMAGE: the image specified by the URL (hosted on GCP) will be added to
Dev & Preview releases. For Stable releases, see the pinned doc in the
#release Slack channel.
* OZ: Oz-related updates. Use `CHANGELOG-OZ`. At most 4 Oz updates are
shown in-app per release.
