Breaking Changes

For supporting garbage collection in the future there is a slight breaking change that Snapshot's will only be valid for the duration of the callback or render. A new retain() API can be used to persist them longer. This is not enforced yet, but Recoil will now provide a warning in dev-mode if a Snapshot is used past its lifetime. (#1006)

New Features / Improvements

• Add override prop to <RecoilRoot> (#973)
• Add getCallback() to selector evaluation interface (#989)
• Improved TypeScript and Flow typing for Loadables (#966, #1022)

Performance Optimizations

• Improve scalability (time and memory) of Atom families by cleaning up a legacy feature.

Bug Fixes

• Throwing an error in an async selector should be properly caught by <ErrorBoundary>'s (#998, #1017)
• Fix for Atom Effects onSet() should not be called when triggered from setSelf() initializing with a Promise or from the same onSet() handler. (#974, #979, #953, #986)
• Improved support for Safari (#967, #609)
• Objects stored in selectors are properly frozen in dev mode (#911)
