New Aseprite v1.1.7 and v1.2-beta1 are available:

Aseprite v1.1.7:

• New option to hide full path in UI
• Fixed theme configuration UI to show user/official folders and themes correctly
• Fixed crash resizing to big sizes (show not enough memory if we cannot resize the sprite)
• Fixed some issue in Import Sprite Sheet dialog
• Fixed crash copying 8bpp images on Windows

Aseprite v1.2-beta1 is available in the Steam beta branch:

• Add new pixel aspect ratio option so we can draw sprites with double-wide pixels
• CLI improvements:
• –frame-tag and –frame-range now can be used with –save-as
• –save-as now interprets {layer} in the given filename to automatic iterate through layers, so we can use –save-as output-{layer}.gif to save each layer in a different file.
• New –split-tags to save each tag as .gif file, anyway you can use –save-as output-{tag}.gif as a shortcut.
