[Jan Fajerski]

Due to an issue in our pipeline to build release artifacts we are
pleased to announce RC1 of the the 3.2.0 release. This release
contains the same changes as the previously announced RC0. Most
notable the following feature and changes:

[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.
