This is purely a bug fix release, so be sure to update if you're using Preact 4.x.
Bugs Fixed:
- Fix orphaned keyed VNodes not being removed in certain cases, such as when there are adjacent non-orphaned non-keyed VNodes (see preactjs/preact-compat#21)
- When diffing a component against a non-component VNode, if the component render returns a different DOM node, make sure to reclaim the original node. (Issue #73)
