2.0.0.rc (December 30, 2020)

** New reconciliation algorithm **

#200

Fre now uses a new diff algorithm, which can traverse from both ends and handle common prefixes and suffixes

This is also the optimization used in Vue, Inferno, IVI and other frameworks, which is much better than react.

** todo **

1. refactor commitWork

Use recursion instead of regenerating a effect list

facebook/react#19673

2. better render array

FragmentDocument for Component and refactor h function.
