Version 2.2.0.7 changes.
Highly recommended update: major new feature, and many bug fixes. 
1.	Major new feature
o	If a template is changed to add / delete /rename controls, image sets opened with an earlier version of that template will detect those changes and incorporate them into the image set. A confirmation dialog box will be displayed.

This feature greatly increases the flexibility of Timelapse, as you can change the data you want to analyze on already-analyzed image sets. 

The user manual has been updated to provide further details
2.	Important bug fixes
o	Fixed an issue where deleting multiple images could crash Timelapse.
