What
When you resume a session, Claude Code reads ahead in its transcript, the saved record of the conversation. That read-ahead now:
has a time limit, and can have that limit lifted
can start partway through the file
retries reads that hang
is skipped on later resumes once a session has been marked as having run out of time
Adding to an existing transcript is also safer. Claude Code now refuses to write if the file changed underneath it or ends in the middle of a line.
Before, the read-ahead had no time limit, only a check for reads that hung.
Why
Very large sessions should not stall when you resume them, and a transcript written by another program at the same time is less likely to be corrupted.
