  • Back again to the good-and-peaceful-allegro-like makefiles. Ok, ok, the GNU style was the worst change in ASE, but now is fixed :-)
  • Removed the .DLL or .so capability for plug-ins. After some weeks of thinking, I decide to strip off this feature because is too hard to do a good system to attach new plug-ins with the current menu implementation. The most user are just "user" and don't will copy the plug-in and modify the menus to add a new entry with a little script-string to call the new plug-in action. Also, this save me a lot of headaches :-)

    • undo_history: to undo/redo various operations.

  • Improved the Color Replace command (with tolerance and preview).
  • A new optimized layer-bar, to handle all the keyframe/properties stuff.
  • Various things rewritten to Plug-Ins:
    • file formats,

ASE v0.0.7 April 19, 2002

  • New full-screen editing mode. With resizable layer-bar.
  • Added an options to draw the previous frame in transparent mode.

  • New reload_menus command.

ASE v0.0.6 February 5, 2002

  • I still don't recommend you the .ase format (just for temporary usage): there are planes to change it.
  • Scripting capability athwart Lua language: now, you can make automatic tasks programming your own scripts (included some scripts as example).
  • Independent alpha (global transparency) and blender-mode for each layer (like in GIMP and Adobe Photoshop).
