Today we’re releasing Aseprite v1.2.12, a minor version with some bug fixes and a way to restore files closed by mistake:

• New Ctrl+Shift+T (⇧⌘T) keyboard shortcut to reopen last closed file
• Now edited files are kept between sessions just to avoid losing information if something goes wrong (can be disabled unchecking Edit > Preferences > Files > Keep edited sprite data option)
• Restored default brush center behavior
• Fixed eyedropper when zoom < 100% (reported in several places, e.g. report on Steam forum)
• Fixed brush cursor on paint bucket/gradient tool
• Fixed File > Repeat Last Export command
• Fixed bug where the zoom level in the status bar wasn’t updated correctly when switching between sprites
• Fixed crash with invalid grid bounds configuration
• Fixed regression drawing pixel perfect straight lines
• Fixed Blur tool: don’t make the color darker when alpha < 255
• macOS: Fixed issue updating screen immediately after undo
