The ninjas over at Yahoo! released version 2.20 of YUI (Yahoo User Interface). They changed the versioning track, hence the jump from v0.12.2 to v2.20. This release has some really nice additions that I think will be extremely useful for buiding some web apps.
Browser History Manager
As you probably know most web apps have some serious back/forward button issues in browsers. This release claims to make that work now across A-grade browsers. Haven’t had a chance to try it out yet, but sounds very promising.
This looks really cool. Adds sorting, searching, inline editing, and adjustment of presentation of a table just to name a few of it’s features. Very cool.
Enables creation of rich buttons that act like traditional form buttons. Labels can differ from their values which is nice.
