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.

MCP connection dial-out deduped by a once-guard

You'll notice
Useful3 Signal0
MCP

MCP tool and command collection is less likely to hang or finish twice.

What

The routine that walks connected clients to collect tools and commands now uses an explicit once-guard closure instead of counting callbacks against an expected total.

Details
  • Completion can now fire from triggers other than the last callback without double-resolving.
  • Previously the count had to match exactly for the routine to settle.
Evidence

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