## Activity for September 2026

## Suggested Actions for Maintainer

**Comprehensive list** of all pending actions requiring maintainer attention (excludes items already actioned and checked off).

* [ ] **Close issue** [#14454](https://github.com/dotnet/fsharp/issues/14454): Regression test PR [#20251](https://github.com/dotnet/fsharp/pull/20251) was merged but the issue was not auto-closed — please close manually
* [ ] **Check comment** on [#16464](https://github.com/dotnet/fsharp/issues/16464): confirmed still present, Repo Assist provided repro details — [View](https://github.com/dotnet/fsharp/issues/16464#issuecomment-4152823471)

## Additional observations for maintainer's attention

* Issue [#16292](https://github.com/dotnet/fsharp/issues/16292): **Debug-only codegen bug** — SRTP with mutable struct enumerator causes infinite loop in Debug builds.
* Issue [#11929](https://github.com/dotnet/fsharp/issues/11929): Calling protected static base member from `static do` — confirmed still reproduces without `--realsig+`, and IS fixed with `--realsig+`. Will resolve naturally when `--realsig+` becomes the default.
* Issue [#14585](https://github.com/dotnet/fsharp/issues/14585): VS Error List shows more errors with Build+IntelliSense than Build alone — likely Roslyn issue (linked to dotnet/roslyn#19693).
