Release notes are adopting a new structure from 9.0, identical across
all Elastic products. Pages are broken down as follows:
- A main page listing all new features, enhancements, and bug fixes.
Each new release gets added to the same page. (9.1 will be above 9.0,
etc.)
- Subpages for breaking changes, deprecations, and known issues.
- There is no longer a "What's new page". This is replaced with a link
to the blog's release announcement from this page, that will be the
"home page" for release notes in the new assembled docs website:
https://staging-website.elastic.co/docs/release-notes/ (not visible in

Note: More files are deleted than added here because the content from
some files was moved to
[elastic/docs-content](https://github.com/elastic/docs-content).
**What has moved to
[elastic/docs-content](https://github.com/elastic/docs-content)?**
Public-facing narrative and conceptual docs have moved. Most can now be
found under the following directories in the new docs:
- explore-analyze: Discover, Dashboards, Visualizations, Reporting,
Alerting, dev tools...
- deploy-manage: Stack management (Spaces, user management, remote
clusters...)
- troubleshooting: .... troubleshooting pages
**What is staying in the Kibana repo?**
- Reference content (= anything that is or could be auto-generated):
Settings, syntax references
- Release notes
- Developer guide
