Prometheus 3.2.0-rc.0 is available

[Jan Fajerski]

We are pleased to announce that Prometheus 3.2 has started its life
cycle with a number of changes, enhancements and bug-fixes.
There are two changes in behaviour and one new feature:

- [CHANGE] relabel: Replace actions can now use UTF-8 characters
in targetLabel field. Note that $<chars> or ${<chars>} will be
expanded. This also apply to replacement field for LabelMap action.
#15851
- [CHANGE] rulefmt: Rule names can use UTF-8 characters, except {
and } characters (due to common mistake checks). #15851
- [FEATURE] remote/otlp: Add feature flag otlp-deltatocumulative
to support conversion from delta to cumulative. #15165


Please try out the release candidate on a non-critical environment and
let us know what you find.
