Claude Code v2.1.222

Screen-reader rendering erases trailing characters in place

You'll notice

Elsewhere not in their notes

Screen-reader mode repaints less, so assistive tech hears less redundant output.

What

In screen-reader mode the renderer can now erase trailing characters instead of repainting the line, cutting redundant output for assistive tech.

Details
  • Diffing tracks a new prevScreenReaderParkDeclared flag.
  • The flag guards a new branch taken when the previous frame had an explicitly declared cursor park.
  • Only active in screen-reader mode, under INK_SCREEN_READER / CLAUDE_CODE_ACCESSIBILITY.

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