This release fixes major bugs found in 1.6.0a1.
Childsites like columns, notebook pages, panes, toolbar buttons, etc. can now have their options saved or not using checkboxes, like in the attributes editor. This allows easier porting to other platforms and reduces the project size as well.
Support has been added for the BLT barchart widget.
Feedback, bug reports and feature requests welcome. Whenever possible, please use the trackers on SourceForge for bug reports or feature requests, so that we have a record. Thanks!
