A side-by-side editorial comparison of Grafana Loki and ThingsBoard — release velocity, themes, recent moves, and the top alternatives to consider.
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.
ThingsBoard closes a script-sandbox file write and dozens of CVEs on its 4.3 and 4.2 lines.
ThingsBoard keeps three lines patched in parallel: 4.4, 4.3.1 and the 4.2 LTS. On October 27, 4.3.1.8 and 4.2.2.8 shipped a large security batch, including a fix for arbitrary file writes from the TBEL script sandbox and tamper protection for the OAuth2 authorization cookie. On October 30, 4.4.0.2 followed with security patches, though its notes list no details.

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.

On October 30, 4.4.0.2 followed with security patches, though its notes list no details.
After the 4.4 feature release the project is back to maintenance on all supported lines, mostly security and runtime fixes, with the IoT Hub catalogue getting steady UI work alongside. Feature work arrives in larger, infrequent releases.
Expect the next entries to be routine patches across all three lines. The notes do not say whether 4.4.0.2 carries the same fixes as the 4.3 batch.
