I have been spending a day working with EXTJS v4.0 BETA 3.
It feels like bit like I am entering a nightmare, but I am new to JS and EXTJS so that may explain it.
I am working on a new project, but i suspect I do not require any functionality which EXTJS v3.x does not offer. Would people recommend I stick with EXTJS v3.x?
When will EXTJS v4.x release? How long until that is considered safe/mature for real use?
