Tightening a team's default permission mode to Manual is a one-line settings change interactively and a silent outage in CI, because headless runs turn every ask into a deny and still report success. Measured on Claude Code 2.1.224, including the trust gate that drops your allowlist but keeps your mode.

Labeled break and continue landed in the C# section of .NET 11 Preview 7. You can now put a label on a loop and jump straight to it, which retires the bool flag and goto workarounds for nested loops.

Every way dotnet tool install --global dotnet-ef fails on the .NET 10 SDK, with the exact message and exit code for each: already installed, version not found, downgrade blocked, shim conflict, dead NuGet feed, and the runtime mismatch that only breaks after the install succeeds.

CS9137 comes from the Microsoft.AspNetCore.OpenApi source generator. Add InterceptorsNamespaces to every project that calls AddOpenApi, not just the one holding the PackageReference.

The 1M-token context window is now the default on Claude Opus 5, Opus 4.8/4.7/4.6, Sonnet 5, and Sonnet 4.6, with no beta header and no long-context premium. Here is when deleting the vector store actually pays off, the 10x cache-read rule that decides it, the ~30% tokenizer inflation that breaks your sizing estimate, and the seven-step migration with a verification line on each one.

Claude Code 2.1.224 adds claude self-hosted-runner, a public beta that executes cloud sessions on machines you provision. Here is the setup, the one-user runner rule, and what still leaves your network.

OpenApiReference was deleted in Microsoft.OpenApi 2.0. Changing the using to Microsoft.OpenApi is not enough: replace each usage with a typed reference such as OpenApiSchemaReference.

Radio.groupValue and Radio.onChanged were deprecated after Flutter 3.32 and RadioGroup shipped in 3.35. A step-by-step migration for Radio, RadioListTile and CupertinoRadio, why dart fix cannot do it for you, and the generic type-inference trap that silently renders a migrated radio disabled. Verified on Flutter 3.44.2 stable.

Two different things get called a modal window in .NET MAUI 11. PushModalAsync gives you a modal page on every platform. A real OS window that disables its owner has no MAUI API at all, so here is the WinUI OverlappedPresenter.IsModal plus Win32 owner-handle interop that actually works on Windows, and what to do on Mac Catalyst instead.

The GitHub, Postgres, and Slack MCP servers from modelcontextprotocol/servers were archived in 2025 and their npm packages are deprecated. They pin SDK 1.0.1, which cannot negotiate past protocol 2024-11-05. Here is the audit script, the current replacement for each, and the two pointers in the archive README that are themselves stale.
