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 Dovetail — 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.
Dovetail opens its docs to Claude and ChatGPT as co-authors.
Channels 2.0 reached general availability on October 21, with activity logs, snapshot summaries and a Sources beta for feedback integrations. In early November Dovetail let Claude and ChatGPT read and edit Dovetail docs from the conversation, offered access to teammates who are @mentioned in a doc they can't open, and taught its own Chat to answer how-to questions from the help docs.

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.

After the Channels work, the focus has moved to docs and the assistant layer: external AI assistants now write into Dovetail, and the in-app Chat covers product help as well as research questions. Dovetail is positioning its docs as a place both people and outside assistants work in.
Expect more actions exposed to external assistants beyond docs, such as channels or evidence, and further Chat coverage of in-product tasks.
