+1 (binding) Validated 4.2.5-candidate-1 on macOS arm64 with Amazon Corretto 21.0.11 and Maven 3.9.9.
- Checked source and server binary SHA-512 checksums and GPG signatures - Verified the source distribution matches the candidate tag - Built from source and passed RAT and LICENSE/NOTICE checks - Passed 40 client tests and 4 broker message-ID tests - Passed all 7 standalone tests after adjusting local BookKeeper disk thresholds; the initial run hit read-only bookies because the test host exceeded the default disk-usage threshold - Verified nonpartitioned and two-partition topic produce/consume and recovery after restart I did not run the full integration suite, upgrade/downgrade tests, or Functions, connector and offloader runtime tests.
