What

In remote sessions, Claude Code downloads attached files ahead of time so they are ready when needed. When a remotely controlled switch is on, it now also starts a second download of each attachment, a copy intended for the model. Before, it made only one download.

The limit on how much downloaded data Claude Code holds at once now counts what is actually held in memory.

The switch read on for this site's account and for an anonymous account in the most recent reading, taken before this release. It had been off in the reading before that.

Why

This changes how images and files reach Claude in remote sessions, and holding two copies uses more memory, which the updated limit is set up to track.

The shipped code defaults this off, and the flag server returned on for the one account this site reads on this version. That is the reading that makes the entry above worth a second look, and it still says nothing about your account.

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.

Read once, for one account on one subscription tier, against v2.1.323. It isn't a statement about your account. What a flag value here can and cannot tell you
