plugins: Cascade adds usage meter

Two releases of plugins shipped this week, with the main change being the addition of a real-time context window usage meter in Cascade, which helps developers monitor context window consumption during conversations. This change is useful for developers working with models in Windsurf. The releases also include various fixes for IDE crashes and formatting issues.

v2.11.3 (Next) · December 3, 2025

Release v2.11.3 includes a new feature that displays a real-time context window usage meter in the footer of Cascade, as well as several patch fixes, including resolved IDE crashes and fixed code indentation formatting issues. The most notable fix is the resolution of IDE crashes during Cascade Diff. This release helps developers monitor and manage context window consumption during conversations.

  • The new variable thinking feature dynamically adjusts reasoning depth—providing quick responses for simple tasks and more thoughtful analysis when complexity demands it.
  • Priority processing support for GPT-5.1 models, providing guaranteed low-latency responses for faster (~50 tokens/sec), more reliable AI assistance.
  • Priority processing costs 2x the standard rate, which will be reflected in the Windsurf credit system.

Gemini 3.0

  • You can now use Gemini 3 Pro (Low and High) in Windsurf!

Features
