 ### Fixed
 
-- An F# file that type-checks but that Fable cannot translate now fails `vite build` instead of passing for a successful compile. `Fable.Compiler` filled a compile's diagnostics from the F# type-check only and discarded Fable's own logs, so a call like `Async.RunSynchronously` produced a module that does nothing while the build printed nothing and exited 0, and the app broke in the browser. Fixed upstream in [fable-compiler/Fable#4923](https://github.com/fable-compiler/Fable/pull/4923), which this release picks up: the daemon now reports what Fable said alongside the F# diagnostics, for the first compile of the project as well as for every recompile after an edit, so these errors reach the terminal, the browser overlay and `/api/diagnostics`. They carry no error number, so they are named by their tag — `ERROR FABLE:` where an F# diagnostic reads `ERROR FS0025:`. Diagnostics on files under `fable_modules` are still dropped unless `fableModulesDiagnostics` is on.
