Improvements:
2+
3+
* In order to combat the issue of border halfchars forming around images, new aspect ratio preservation modes have been
4+
added as follows:
5+
* Snap to char (new default) - rounds width/height to the nearest character.
6+
* Snap to center - rounds width/height to the nearest character which allows the image to be centered.
7+
* The aspect ratio preservation mode is now saved as part of the profile.
8+
* The window title now displays the program version.
9+
10+
Bugs fixed:
11+
12+
* The window pane showing scroll bars when unnecessary on some platforms has been fixed.
13+
* The correct program version is now displayed (regression in 0.4.2+).
