 * Fix FSI pretty printing to distinguish anonymous records (`{| ... |}`) from nominal records (`{ ... }`). ([Issue #6116](https://github.com/dotnet/fsharp/issues/6116), [PR #19919](https://github.com/dotnet/fsharp/pull/19919))
 * Fix dot-completion after indexed expressions (`a.[0].Data.`, `a[0].Data.`, `[1;2].Length.`) returning unrelated global completions instead of expression-typings members. ([Issue #4966](https://github.com/dotnet/fsharp/issues/4966), [PR #19934](https://github.com/dotnet/fsharp/pull/19934))
 * Quotations of `match s with "" -> _` no longer leak the `s <> null && s.Length = 0` lowering; the empty-string optimization moved from pattern-match compilation to the optimizer so quoted expressions keep `op_Equality(s, "")`. ([Issue #19873](https://github.com/dotnet/fsharp/issues/19873))
+* Parser: recover on unfinished abstract members ([PR #20070](https://github.com/dotnet/fsharp/pull/20070))
