I updated the ooDialog preview build on SourceForge:
This will be the last preview build before an official beta. The current plan is to start the beta of 4.2.2 in the first week of March with a release around the last week in March.
So the current preview is pretty much what the 4.2.2 release will have in it. The only change will be the doc. The only things left are a small portion of the BrowseForFolder class and about 50 % of the ResizingAdmin class.
