v0.7.0

[0.7.0] - 2026-09-09

Added

• Neovim 0.13.x multicursor overlay support through win_extmark, including
  namespace discovery and stale cursor cleanup.
• A --health-check command that reports operating-system, display, graphics,
  and GPUI renderer information.
• Windows custom titlebar icons for minimize, maximize, restore, and close.

Improved

• Startup diagnostics now provide clearer graphics-backend and display errors,
  including Vulkan, OpenGL, and platform GPU probes.
• Invalid nvim-gpui options are rejected before Neovim starts. Neovim options
  can be passed explicitly after --.

Fixed

• Windows custom decoration maximize/restore behavior and titlebar button
  hover states.
• Neovim startup failures no longer leave an unusable empty GPUI window open.
