What
When Claude Code passes its output to another program as it is written, it collects small pieces into batches and sends them on a timer. If a timer is already running and Claude Code is not in slow mode, each new piece of streamed content now goes straight into the batch, skipping the check it used to make for every piece.
Claude Code also now counts how many characters of input are streamed for each tool call (each time Claude uses one of its tools).
Why
This is a faster path for streaming. It may change how output arrives in batches for remote sessions or for programs that drive Claude Code.
