Good morning. This is your VS Code developer briefing for May 8th, 2026.
The team merged 20 pull requests yesterday, with significant focus on Copilot improvements and core editor functionality.
Bhavya U merged a critical fix for historical user message caching in Copilot. The change prevents prompt cache invalidation by ensuring historical messages don't carry live workspace state, addressing a performance issue where cache prefixes broke on every request.
Vijay Upadya added reasoning effort support for BYOK OpenAI-compatible providers. This enhancement allows per-model reasoning effort configuration across OpenAI, xAI, and OpenRouter endpoints, with a new "Thinking Effort" control in the model picker.
Dmitriv MS strengthened snippet session handling against null decorations and selection drift, addressing four telemetry-reported crashes with defensive guards in the snippet code.
Matt Bierner improved markdown preview functionality with broadcast channel support for diff scroll sync, making synchronization faster by allowing direct webview communication instead of routing through the extension host.
