Revision 1150 changed the way angles work so that 0 degrees and 360 degrees are treated as being one whole rotation, rather than as being the same angle.  However, existing .sif files expect animating a tangent from 359 degrees to 0 degrees to be a one degree turn, not 359 degrees.  Until r1150, angle animation always went 'the short way'.  This change bumps the canvas version number to 0.2.  Canvases of version 0.2 or newer use non-wrapped angles.  Loading a 0.1 canvas will convert the angles so that existing .sif files will continue to work.  wiki.synfig.com/Image:Eyes.sif at 3s 16f is an example of a .sif file that was rendering wrongly before this change - the black shadow under the right eye shouldn't be there.
