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.

Claude Code v2.1.251

Slow uploads get three times as long before the tunnel gives up

Useful3 Signal2
Internals Notable

Tunnel uploads get 180 seconds before stalling out instead of 60.

What

The stall timeout for sending data over a tunnel connection rose from 60 seconds to 180 seconds, so a session on a slow link is much less likely to be dropped mid-upload.

Details
  • Adds tracking of uploaded bytes and pauses, plus a 16MB queued-upload reporting threshold.
Evidence

sendStallTimeoutMs: 180000

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