0.16.0 - 2026-08-11

What's Changed

Features

• feat(config): add fetch_max_bytes and segment_max_records backup options (#140)

Full Changelog: v0.15.13...v0.16.0

---

Release Notes

Added

• backup.fetch_max_bytes — maximum bytes requested per Kafka Fetch request,
  decoupled from the segment size (previously always
  min(segment_max_bytes, 16MB)).
• backup.segment_max_records — rotate segments once they hold this many
  records, in addition to the existing size/interval thresholds.
• Warn on unknown config keys at load time instead of silently ignoring them.
  Requested in
  strimzi-backup-operator#53.

Changed

• kafka-backup-core: BackupOptions and SegmentWriterConfig gained new
  public fields (breaking for struct-literal construction; use
  ..Default::default()).
