We are still developing on the 4.2 branch so right now it's planned.
Mitchell, thank you for reopening the thread. I have made some harsh comments in this thread but it's really out of love for the framework =). I have used ExtJS from 2.1 to 4.2, and I want it to be successful because my butt is on the line for vouching for the framework to my company. Would you be able to tell us if more performance improvements are coming in 4.2 and beyond? The major issues are:
1) DOM generated in IE7/IE8 can be greatly optimized by reducing number of table elements. Divs used in 3.4 are now replaced with table wrappers. This is very evident in form fields.
2) Layout engine seems to calculate layout more often than needed.
I am quite disappointed about a fourth version and it's grid component. I have written lots of grid components in my life but this is just silly. Back in 1997 I already wanted to add components in grids. Hence I wrote this. Why does a solution like Ext JS 4 and its grid doesn't support it? I don't get it.
Yes, the grid gadgets is really interesting. Only I haven't found any clear indication when ExtJS 5 would be come available. Be it production or a beta. We currently hacked the cell editing plugin to fulfil our needs but its not great.
Obviously, you'll see 4.2.2 and 4.2.3 before any 5 beta. From SenchaCon, they were still pondering if they should put some new features in the 4.x line vs. the 5. So, we'll still be seeing new features along the way. What are those? Don't know.
roadmap, no issue tracker with future ERs, nothing.
I get that they want to keep some surprises in store and prevent competitors from stealing their thunder, but they just take this too far. Companies and developers need something, anything, to plan against. Please, Sencha, loosen up a little and give the people using your products a little bit of information and insight on what you're planning.
