DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.
Analytics shutdown waits for queued work before closing sinks
Under the hood
Useful1Signal2
Telemetry
Analytics now drain queued events before shutting down, so crash-path events have a chance to send.

What
Shutdown now drains a queue of pending analytics tasks, raced against a 200 ms timeout, before the event logging, Datadog and error-tracking sinks are closed. The first user of this is the MCP tripwire event, so an event fired on a crash path now has a chance to be sent instead of being dropped at exit.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
