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 v2.1.233

SSE transport state checks inlined and one error event dropped

Under the hood
Useful1 Signal2
MCP

An MCP event-stream error report is no longer emitted anywhere in this build.

What

The MCP server-sent-events connection replaced its closed-state helper with inline checks, and the stream-read path now bails when its abort signal fires. The cli_sse_close_handler_threw event is no longer reported anywhere in this build; cli_sse_stream_read_error is unchanged.

Evidence

cli_sse_stream_read_error

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