What's the key thing new to 3.5.1
 

I have 3.4.9 installed and want to know if it is worth the time to upgrade. I confess to know little about programming and love the ease of 3.4.9. I assume that 3.5.1 will have the same interface and the same options. Still learning. still trying to figure things out. Thanks.

Yes upgrade! Remember you can install the theme to a new folder (atahualpa351) and switch.

The bug causing flaky results coming from 3.4.6 or earlier is fixed,
import/export of the style works
resolved a bug in 'excerpts'
corrected an error in one of teh new styles.
and finally, any bugs found in 3.4.7-3.5.0 will have fixes made but only to 3.5.1

besides, it takes all of 10 minutes to upload the new version...
