What’s in this release
- Targeted bug fixes addressing crashes, stability regressions and corner-case parsing errors across common sources and sinks; memory-leak fixes and improved error handling.
- Runtime and resource improvements: reduced memory footprint for high-throughput pipelines, more efficient batching and backpressure behaviour, lower CPU overhead for common transforms and steadier throughput under burst load.
- Integrations and tooling updates: minor compatibility and auth/TLS tweaks for cloud destinations and HTTP/remote delivery, plus refreshed documentation and updated CLI/help text.
Upgrade notes
- Run the documented config validation and recommended pre-upgrade checks before upgrading; consult the release notes for any deprecation notices and step-by-step guidance.
- If you need to roll back, follow the typical rollback steps outlined in the release notes and verify your CI/tests in the target environment.
