We have released v3.4 last Friday morning (US Pacific Time), but soon after we have found a regression bug with Excel data import. So we have quickly fixed it and released an urgent patch on Saturday (US Pacific Time).
Here’s the release note for all the enhancements and bug fixes.

The main things about v3.4 is the internal R version being upgraded to R 3.4, (which is coincidentally matching with Exploratory’s version number so don’t get confused!) and the performance improvements for opening data frames and SQL / MongoDB Query Editors.
There is also a slight UI update. Now there are Export and Publish buttons at the top, whic makes it easier to access these menus and there are a few surprises there, go find them! 
Cheers,
Kan
