Hi,
I did the following:
- verify all signatures
- build from source (OpenJDK Temurin 17 + Scala 2.13)
  - This test fails consistently on my machine, but I tried with 3.8 and
3.9.0 and it also fails LazyDownConversionRecordsTest >
testConversion(CompressionType, byte, boolean) > compressionType=gzip,
toMagic=1, overflow=false. I'll try to investigate if something is wrong on
my end.
- Run quick start with KRaft
- Run quick start with ZK
- Verified JavaDocs and verified that backlinks to Oracle's Java work
- LICENSE-binary has the right versions

+1 (binding)

Thanks for the release!
