Aseprite v1.2.13

Today we’re releasing a new version with an important fix for a crash using reference layers (you should update your version), and a couple of new features:

• Added new Edit > Paste Special options to paste the clipboard content into a new sprite or layer:

Edit > Paste Special > Paste As New Sprite

- 

Edit > Paste Special > Paste As New Layer (Ctrl+Shift+V) - Edit > Paste Special > Paste As New Reference Layer

• Added Layer > New… > New Layer Via Copy/Cut options to convert the selection into a new layer (Ctrl+J/Ctrl+Shift+J)
• Fixed crashes using Reference Layer or Import Sprite Sheet (reported via email with several .dmp files, and Steam forum, etc.)
• macOS: Fixed showing file name extension on native file selector
• macOS: Fixed Command+Z/X/C/V/A keyboard shortcuts on native file selector
