• Preview of ACP-based agent support in Visual Studio, starting with Junie, JetBrains' own LLM-agnostic agent.
• Out-of-Process mode is now enabled by default.
• dotTrace, dotMemory, and Monitoring now work in Out-of-Process mode.
• Improved C# analysis with more collection-expression cases and enhanced Extract Method that detects duplicates.

• Revamped Import missing references popup with no flickering and smarter placement.
