 ## Changes
 
+* v0.2.16 - Added ability to specify directory where timelapse images will be saved.
 * v0.2.15 - Added `-n` flag to limit the number of timelapse pictures. Also changed first timelapse image numbering to start at one instead of zero.
 * v0.2.14 - Bump to fix distribution problems only
 * v0.2.13 - Default warmup period is now three seconds.  Set ```-w 0``` if you want no delay.
