## Summary
Refreshes the docs for the v3 sunset: v3 (SDK v3) is end of life, and
4.5.0 is the last version we officially support for running v3.
- The self-hosting overview, plus the docker and kubernetes
version-locking sections, now tell self-hosters on v3 to stay on 4.5.0
or migrate to v4. 4.5.1 and later reject v3 triggers and deploys with an
upgrade message.
- The migration guide's deprecation notice was still written in the
future tense (with dates that have since passed); it now describes v3 as
retired and adds the self-hosted 4.5.0 cutoff. This is the page the
server's upgrade message links to.
- Fixes a stale "v3 project" reference in the CLI overview.
The Mintlify preview will render the callouts for a visual check.
