Version 2.2.5.0 Update strongly recommended – many significant changes
Odd behaviours or crashes? Feature requests? Questions? Please let me know.
Important. This version introduces changes affecting backwards compatibility. Using an earlier Timelapse version to re-open a Timelapse database is still possible, but several functions will not work properly (e.g., Episode and Custom Select on DateTime).  To be safe, always use the latest version of Timelapse.
1.	User manual, practice image set, videos
o	Manuals are completely re-written as six separate guides with new practice image sets. This includes
•	a Quick Start Guide that walks people through various basic Timelapse features.
•	Detailed Reference Guide and Template Guide
•	an Image Recognition Guide (plus companion video) 
•	two practice images sets accompanying the guides, with one being specific to image recognition. 
•	Companion videos for several of the guides
o	See https://saul.cpsc.ucalgary.ca/timelapse/pmwiki.php?n=Main.UserGuide. 
2.	Enhancements to existing features (almost all based on users requests)
o	CSV Import 
•	now imports dates and times (if its in the correct format) and folder names
•	is much, much, much faster with very large data sets
o	Options | Preferences | CSV Export has significant changes to how dates and times are exported. 
•	Importantly, a space can be optionally inserted before the fields, which stops Excel from changing date/time fields into its own internal format.
•	The UTC DateTime export option has been removed.
o	Populate metadata 
•	Edit | Populate one or more fields with metadata dialog now allows you to choose multiple metadata field to populate at a time
•	Options | Preferences now includes a Populate fields with metadata as new files are loaded panel. If selected, it will populate your selected metadata fields whenever new files are added. This gives you the choice to populate metadata in a single operation. 
o	DateTime and UtcOffset changes 
•	Dates/times are now recorded in local time, with UtcOffset set to 0.  Older database, when opened, updates to local time as needed.  You shouldn’t notice a change unless you use the UtcOffset
•	Only the Date and Time columns will now appear in the Data Table view (DateTime and UtcOffset columns are removed).
o	Image recognition 
•	Bounding boxes and other recognition features are automatically enabled after recognition data has been imported. The option to turn it on manually has been removed.
•	Custom Select now includes an option to include all files in an episode when at least one file matches. This feature is useful for cases when the analyst wishes to review all files in an episode in order to best identify, validate the recognition prediction.
o	Episodes
•	Options | Preferences... now includes an Episodes panel that lets you adjust how many surrounding files Timelapse should examine to determine the episode length (it formerly only looked at a maximum of 99 files before giving up, due to performance concerns). This has been increased substantially, where you now have the option to increase it even more.
•	Options | Adjust episode time threshold can now range from 1 second to 10 minutes, where that time separation determines if adjacent files are grouped into an episode.
o	Help menu updated to include menu items that point to the new guides and practice image sets
3.	Database changes
o	Dates and Times recorded in the .ddb file are now stored in local time rather than in UTC format. The UTC column is still there, but set to UTC 0.0. These date/time changes affect backwards compatibility as mentioned above.
