Note:
Due to large number of likely new Flow errors that will be introduced in the next release, we decided to create an extra release to ease the upgrade process.
We announced in the recent blog post that we would remove the enforce_local_inference_annotations option in flowconfigs, as it became the default in v0.189.0. This change will be delayed to v0.191.0 instead.
Likely to cause new Flow errors:
- Flow will now error on indexed write to exact objects without indexed type.
- Flow now requires that the target of
extendsclauses in class definitions are either variables, casts, or member expressions, rather than allowing arbitrary expressions. - We fixed a bug in which type arguments were not passed to the type parameters of static callable methods.
- We unblocked constraints involving
anyand type applications likePromise<T>, which may cause new downstream errors to be discovered.
Notable bug fixes:
- Fix a bug that can cause the Flow server to unnecessarily restart when Watchman restarts
