++ Fixed cursor going invisible when escaping from import in the editor
++ Fixed robot editor entry when pressing OK on global info
++ Fixed lack of name for MZB import/export (any MZB's exported in prior
+  beta versions still won't have a name)
++ Fixed some problems with setting the mouse position
++ Fixed problem with exits not bringing you all the way to the edge if width
+  over 400 or height over 200
++ Fixed bug that cleared too much when increasing both width and height while
+  resizing the board
++ Fixed problem with 1 char shortcut commands with spaces immediately after them
++ Fixed problems with load_robot and load_bc (caused crashes and infinite loops)
++ Optmized RASM heavily (this should be most noticable when doing a lot of
+  external robot loading from text files)
++ Fixed inability to use absolute paths in loading a game from command line
++ Fixed lastshot/lasttouch conditions with directions not working
++ Fixed char editor in robots not going into SMZX mode when proper
++ Cleaned up source code so it passes -Wall without complaint and in the process
+  corrected some glaring code errors that may have corrected random problems
++ File opening broken in 2.80c, fixed
++ Implemented MZM2 saving and loading and rewrote mzm.cpp (if anything is changed
+  or fixed regarding MZMs, attribute it to this). MZM2s can be of larger
+  dimensions, smaller filesize for same amount of data, and can store robots.
++ Fixed bug that could cause MZX to crash when making new strings
++ Block operations to overlay when overlay was off caused crashes - fixed
++ Fixed a problem with sprite ccheck2 against other sprites
++ Optimized function counter lookups a bit; speed gain for all counter accesses
+  (especially ones that begin with certain characters such as _)
++ Fixed disassembly error with ' ' character
++ Fixed assembly error where condition extended dir (such as blocked opp seek)
+  was not getting compiled with the dir extension
++ Fixed editor bug where the param was not being cleared when overwriting things
+  by double placement
++ Fixed inability to use counters with playercolor/bulletcolor/missilecolor
++ Added ability to use counters in place of p?? in the robot editor
+  Note - even though this expands functionality of the editor this does not
+  require a version number change because the worlds will still be playable in
+  older MZX versions (and will display correctly in the robot editor - you simply
+  won't be able to correctly edit the commands)
++ Mouse correctly limited to screen edges now
++ Fixed inability to overwrite robots with pushable robots and vice-versa,
+  as well as scrolls with signs and vice-versa
++ Possibly fixed problem with windowing error when editing global robot (?)
++ Fixed disappearing cursor after color selection box with mouse (and other places?)
++ Fixed bug in sprite clipping that caused some to be clipped off inappropriately
++ Made board_id/board_param counters readable
++ Added bound checks for all counters using board_x/board_y/overlay_x/overlay_y
++ Removed ability to put robots, scrolls/signs, and sensors (with the put command in
+  Robotic)
++ Fixed potential direction corruption bug causing directions not to work
+  sometimes even if they display correctly in the robot editor
++ Fixed copy overlay to MZM copying to overlay too
++ Fixed a bug where debug window could display the wrong amount of robot mem
+  and potentially even crash MZX
++ Fixed help_menu counter not doing anything (durr)
++ Changed sprite draw order so they're drawn underneath the message bar,
+  debug box, and time remaining display
++ Changed put p?? in Robotic so it will put default params if available
++ Fixed a bug that could cause copies from overlay to vlayer to not end up at
+  the correct destination
++ Fixed a bug where c?x and cx? would not display correctly in the robot editor
++ Optimized copy blocks a bit using variable length arrays instead of malloc
+

 + Color intensity now gets reset when you enter the editor
