• Feature: Windows Server 2025 runners with the Visual Studio 2026 toolchain are now available. They are the same Windows Server 2025 base image with Visual Studio 2026 preinstalled. Start using them with the labels warp-windows-2025-vs2026-x64-<size>. These are transitional labels. The warp-windows-2025-x64-<size> runners still use Visual Studio 2022. More information on the Runners page.

• Feature: WarpBuild Checkout - add special handling for shallow clones, so full base mirror download is avoided.
• Feature: WarpBuild Checkout — A drop-in replacement for actions/checkout that serves your repository from a cache on WarpBuild runners instead of fetching it in full from GitHub. It keeps a git mirror of your repo — a full base bundle plus a per-branch delta — and seeds it before checkout, so the fetch from GitHub is reduced to just the new commits, cutting the request load on GitHub. Swap actions/checkout for WarpBuilds/checkout@v7; it falls open to a standard checkout if the cache is ever unavailable. Learn more at WarpBuilds/checkout.
• Fix: MCP server — Fixed the WarpBuild MCP server showing a persistent connection error in clients like Cursor by keeping its SSE stream alive; tool calls were unaffected.
