v2.5.12

Bug Fixes

• core: revert prop object validation 01c0750, closes #7279

Improvements

• core: allow symbol as vdom key bacb911, closes #7271

• core: prop bindings with inline Object/Array literal values no longer cause the child component to always re-render:

  <foo :bar="[1, 2, 3]"/>

  The compiler now automatically wraps the literal value as an inline computed property to avoid creating new values on each render (unless data it depends on has changed).

• types: extract VueConfiguration type for easy expansion (#7274) c0d516c, closes #7273
