Sencha is being releasing every new version until now with a monthly basis, so, I guess RC2 will be the same.
I hope the not make this next release the final GA, like they did with 4.0GA. It would be nice and correct they release as many RC are needed, until we have a full stable version.
Ext is terrific!!
I just hope there is a RC2 before final. I am still seeing layout failures in RC1 that I hope are fixed in RC2 so I don't have to dig.
I didn't see checkboxmodel's selection mode defaulting to SINGLE in the release notes as a known but, but I see it as an open issue still in the bugs forum. Do you know if it's one of the items to be fixed in RC2/GA?
A couple more I was wondering about were:
comma separated selectors in controllers' control function (works ok in Ext.ComponentQuery.query(), but not in control). http://www.sencha.com/forum/showthread.php?173973-4.0.7-amp-4.1-B1-Comma-separated-selector-breaks-in-controller.control%28%29
And Placeholders which I think Don had said should be fixed in the next release, but wanted to just touch base since the bug looked like it might still be open.
What's your expectation performance wise (IE 8), will we be getting the same level of performance as 2.x or 3.x?
