DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs.

What
The message explaining why a changed file did not make it into an upload lists an extra reason, and there is a new note for tracked files that disappeared while being read.
Details
The added reason covers files still being written at the moment they were read.
Files that vanish mid-read are uploaded as deleted, and the new message says so.
Evidence
or still being written while read
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
