GitHub Desktop 3.6.0, released June 26, brings a graphical worktree workflow and routes Copilot into commit messages and merge conflicts, with a model picker and BYOK.

Microsoft rated the Copilot command-injection flaw Critical, with a 7.7 CVSS base score. It was already mitigated in the cloud and not exploited.

Microsoft open-sourced its Eclipse IDE Copilot plugin on May 21, releasing roughly 15,000 lines of Java under MIT and drawing 1,200+ stars within hours.

GitHub launched a native desktop app for Windows, macOS, and Linux that runs multiple isolated Copilot agent sessions in their own git worktrees and ties them back to issues, pull requests, and merges.

GitHub moved custom runner images out of preview on March 26, exposing a snapshot keyword that turns a workflow run into a versioned VM image — and Copilot's own cloud agent cut another 20 percent off its cold start using it.

GitHub froze new Copilot Pro, Pro+, and Student sign-ups on April 20 and announced a June 1 switch to AI Credits, with the Opus 4.7 multiplier rising from 7.5x to 27x.

The Copilot SDK, now in public preview with support for five languages and bring-your-own-key authentication, exposes the same agent runtime powering GitHub Copilot CLI as a programmable library for building custom AI-driven tools and workflows.

GitHub's new opt-out policy lets it use code snippets, prompts, and context from Free, Pro, and Pro+ users to train AI models, drawing sharp criticism from developers who call it a bait-and-switch.

Microsoft's Visual Studio 2026 ships with AI agents for profiling and debugging, a decoupled build system, 50% faster solution loads, and full backward compatibility — positioning the 30-year-old IDE against Cursor and VS Code in the AI coding era.
