Version 0.27.0

[Kludex]

Description

As I've mentioned before informally, the intention of this release is to be the last before we move to 1.0, not considering eventual patch releases for 0.26.0 0.27.0.

The intention is that between 0.26.0 0.27.0 and 1.0, there will be only:

• removal of deprecation code.
• add deprecation policy to the documentation.

The idea is that between those two versions, we don't have surprises. There's already a draft release for 1.0 here - which needs to be rebased.

Checklist

All the help here is wanted. Reviews, concerns and feedbacks are welcome. 🙏

Plan

As we discussed some months ago, on one of the encode meetings, Starlette can be considered stable, and we shouldn't even need to wait for something to happen to release 1.0. That said, we also agreed that we were going to solve some last issues and PRs, so we wouldn't need to make major releases that soon.

The plan that I had in mind is to release 0.26.0 0.27.0 after we solve the checklist (again, feel free to tell if you think we are missing things there), and then wait 3 or 4 weeks to release 1.0, giving time for hotfixes.
