Likely to cause new Flow errors:
- Remove the
flow get-importsCLI command. - Some duplicate errors with
Arrays are invariantly typedexplanations are now correctly removed.
New Features:
- Added type-aware autocomplete in IDE for switch cases.
- Added signature help to IDE for constructor calls.
- Go-to-definition in the IDE can now provide multiple options if the target is defined in multiple locations (for example, in a union).
- Add
RequiredandPartialto list of utility types to autocomplete in the IDE. - Added quick fix in the IDE for missing "this." on class member access.
- To use the extract to expression/type alias IDE refactors, you no longer need to do exact selections to trigger it. Any selections that include extra whitespaces will be OK too.
Notable bug fixes:
- Fix go-to-definition in IDE for constructors (e.g.,
new Foo()). - When considering a function as a callable object type, we now also check the statics of the function against the object. This may cause new errors. For example, the code in this try-Flow will now error.
- We now error more consistently when nested union types are being spread. Before, a bug was causing legitimate errors to not be surfaced. Example with [cannot-spread-inexact] errors: try-Flow. Example with type incompatibility: try-Flow.
- Some spurious underconstrained-implicit-instantiation errors might be removed. Previously, some classes that extend
anymight have caused this issue. - Fix over-eager IDE autocompletion of keywords after typing a space.
Library Definitions:
- Added NodeJS
process.hrtime.bigint(). - Many built-in react components and intrinsics props are now readonly.
