What probably matters to youSection of the release
What
Claude Code can decode win32 input-mode key sequences (ESC [ params _) that some Windows terminals emit, turning them into normal key input including function keys, ctrl/alt modifiers and repeat counts.
Details
The input parser now carries a high-surrogate field across chunks so emoji and other surrogate pairs split across reads are reassembled.
The terminal private-mode table gained WIN32_INPUT_MODE: 9001, and its enable/disable sequence constants moved out of lazy module init.
Evidence

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