Calibre MCP lets your coding agent read RUM and Lighthouse data, then fix the slow code
A side-by-side editorial comparison of Delta Lake and ThingsBoard — release velocity, themes, recent moves, and the top alternatives to consider.
Delta Lake's public stream is Databricks builds and code cleanup on the way to 4.5.
Recent Delta Lake activity is release mechanics. The newest entries are a Delta Kernel 4.5.0 Databricks build, the removal of unused V2 streaming snapshot code, and CI changes that pause idle source-build jobs now that Spark 4.0 to 4.3 use published artifacts. The last user-facing fix in the window is still 3.3.3's log cleanup correction.
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.

The 4.5 line is being prepared in the open through kernel builds and cleanup, with the Spark connector consolidating V2 streaming onto the V1 snapshot path. The feed shows no 4.5 release notes yet.
A 4.5.0 release candidate or tag is the next visible step; until then expect more kernel builds and cleanup PRs.

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.
