OpenMetadata
OpenMetadata 2.0.8 widens Hex, Sigma and BigQuery coverage while 2.1 waits in release candidates.
A side-by-side editorial comparison of Apache Druid and Grafana Loki — release velocity, themes, recent moves, and the top alternatives to consider.
Druid tags 39.0.0 rc1 five weeks after 38, a faster turn than recent majors.
Druid 38.0.0 shipped on October 1 with Java 25 support, Java 17 dropped, Historical tier aliases and a realtimeSegmentsMode query context. On November 6 the project tagged druid-39.0.0-rc1, about five weeks later. The tag carries no release notes yet.
Loki 4.0 reaches RC3 and narrows S3 storage classes to Standard and Standard-IA.
Loki 4.0 is moving through release candidates. RC1's notes list the breaking changes: the V2 query engine unplugged, Simple Scalable Deployment targets and old /api/prom endpoints removed, protobuf as the default frontend encoding, and several deprecated settings and metrics dropped. RC2 removed every index backend but TSDB, and RC3 adds one more break, limiting S3 storage classes to STANDARD and STANDARD_IA, plus a compactor delete fix.

Majors have arrived every three to five months with 190-255 changes each; a 39 candidate five weeks after 38 shortens that gap. What 39 contains is not visible until the final notes publish.
Expect the 39.0.0 final within one to three weeks, following the rc-to-final gap of earlier majors.

Each candidate trims a bit more legacy surface, so 4.0 is a cleanup major that pushes installs onto TSDB and the microservices or single-binary layouts. The Operator had prepared this path since 0.11 and 0.12.
Expect a few more RCs with small breaking changes, then 4.0.0 GA and an Operator release that drops the removed schemas.
