Claude Code v2.1.208 introduces a plain text rendering mode for screen reader users, enabled via `claude --ax-screen-reader`, `CLAUDE_AX_SCREEN_READER=1`, or setting `"axScreenReader": true`. Vim mode now supports `vimInsertModeRemaps` to map two-key sequences (e.g., `jj`) to Esc. Enterprise users can set `CLAUDE_CODE_PROCESS_WRAPPER` to force all subprocesses through a specified wrapper. Performance and stability fixes: fast mode auto-resume after switching models, background agent message save-and-retry, binary update session hang fix, context window size accuracy (previously stuck at 200k showing false 100% usage). Session transcript size reduced up to 79x for edit-heavy scenarios, file edit cache limited to 16 MB, multiple memory leaks fixed (MCP stdio server stderr capped at 64 MB, LSP documents kept open, async hook output retained).

Summary basis: official / RSS sourceCompiled from the source scope noted above; the original remains authoritative.
