Suggested change

	- Restore the SQLite "fts4", "fts5", "rtree", and "geopoly" extensions on Mac/Linux
	- Restore the SQLite "fts4", "fts5", "rtree", and "geopoly" extensions on Unix

If you want to retain both, then I'd say "macOS and Linux"

This should be in a ### Preview section

This actually includes uv run, might as well just shorten this

Suggested change

	- Add `-w` shorthand for `--with` in `uvx` and `uv tool run` ([#14530](https://github.com/astral-sh/uv/pull/14530))
	- Add `-w` shorthand for `--with` ([#14530](https://github.com/astral-sh/uv/pull/14530))

We might want to clarify the symlink behavior. We only resolve terminal symlinks in globs, I think? See #13438 (comment). I'd consider it an enhancement rather than a bug since this was not allowed by design before.

We might want to just split #13469 into two notes and link to it twice. One enhancement to support parent paths in cache keys and another to improve the performance of cache keys.

Like this?

- Follow leaf symlinks matched by globs in `cache-key` ([#13438](https://github.com/astral-sh/uv/pull/13438))
- Support parent path components (`..`) in globs in `cache-key` ([#13469](https://github.com/astral-sh/uv/pull/13469))
- Improve `cache-key` performance ([#13469](https://github.com/astral-sh/uv/pull/13469))

I would be inclined to say the .. thing is a bugfix if I'm reading #13469 correctly - it silently was ignoring changes to those files without telling you it wasn't supported, right? (Actually isn't that also true of the symlinks thing?)

[zanieb]

Yeah that seems fine.

I guess I'm not sure what our previous behavior was. Is it "Support parent paths in cache-keys" or specifically "Support parent paths in cache-key globs"? It sounds more like a bug fix if it's just the rather.

I don't really feel that strongly about whether or not it's classified as a bug. My impression is that it was intentionally not allowed. A bug fix would be "Error on invalid cache-key entries", but actually making it work is more of a feature. Do what you want with that though :)

I think it could go either way. I'd lean toward enhancement personally, but only weakly so.
