preactjs/preact 6.0.0

6.0.0 (beta)

on GitHub

npm install --save preact@beta

Features

• Add support for SVG <foreignObject> (#278, thanks @amio!)
• Add preact/aliases import: A copy of preact that includes a createElement() alias (#168/#274, thanks @ngasull!)
• Switch to use event capturing for increased consistency with React (#266/#271, thanks @i-like-robots!)

Breaking Changes

• Discard keyed nodes when diffing children instead of allowing them to be reused unkeyed
• linkState() no longer falls back to components path lookups and no longer auto-invokes functions
  • These features were unused & poorly documented, and added extra weight
• Remove default empty options.vnode hook
  • While this is technically a breaking change, very few people use this API
  • Simply perform an existence check on the previous hook prior to calling it

Bug Fixes

• Fix and tests for regression in 5.7 that could cause nodes to be removed (related to #260/#277)
• Fix initial render failing to reuse certain components when picking up from SSR (#260)
• When swapping between Text, Comment and Element nodes, recycle whole orphaned trees
• Prevent the recycler from collecting non-Element nodes 🐛
• Switch back to the pre-5.7 case-sensitive on prefix for event handler props (#275, thanks @c2h5oh!)
