Welcome to pgrx v0.16.0.

This release contains support for Postgres 18beta2 and has some breaking
changes in that support for pgrx' "hooks" implementation, which has been
deprecated for over a year, has finally been removed.

Additionally, due to unsoundness issues, direct support for using
`heapless` in shared memory has been removed. Users can still do this
themselves, which requires them to assert they're taking responsibility
of possible unsoundness issues.

As always, first install the latest `cargo-pgrx` with:

```shell
$ cargo install cargo-pgrx --version 0.16.0 --locked
```

Then you're free to run `cargo pgrx upgrade` in the root of all your
extension crates.

To pickup pg18beta2 support you'll also want to run `cargo pgrx init` so
that it can be downloaded and compiled.
