- Added Cassandra v4 support, Go ES index cleaner, CLI flag for gRPC max receive size, automatic OpenSearch version detection, and new Elasticsearch options (SendGetBodyAs, extended rollover lookback).
- Updated tooling (Go 1.17, docker buildx target, replaced linters), UI pinned to v1.16.0, and fixed bugs (invalid agent.tags check, panic on empty findTraces, ES integration test fixes).
