CHANGE LOG

Version 1.5 -> 1.5.1
*Improved keyboard focus to prevent situation where games would stop reponding to kepresses after switching tabs
*Updated SketchUp importing to support SketchUp version 8
Added stability fix for the over-shoulder camera
Speech bubbles no longer chop off whatever is behind them (they are also slightly more transparent)
Image preview in drawing tab shows correctly
Fixed community site integration on Windows (Mac was fine already)
Fixed bug where blocks wouldn't connect right when zoomed in
Turned off Quartz rendering MacOSX 10.5, making all terrain drawing operations 1000x faster
Fixed bug where levels could get the same name, effectively erasing one of them
Drastically improved camera smoothness when in over-shoulder mode

Version 1.2 -> 1.5
*Pages expand vertically to fit taller stacks of blocks if needed
*Importing 3D shapes from KML (Google SketchUp files exported in Google Earth format)
*Over shoulder camera takes terrain into account, rising upwards if needed to make agent visible
*Drawing panel for drawing shapes, lines, and images on the terrain
*Project files are now in a zipped form, as much as 90% smaller
*"Online" menu gives direct access to projects on the new community site
*Agents execute even more in parallel, seeing each other as they were before anyone executed the current turn
Added molecule shapes to models library
Fixed bug that sometimes caused project files to be unloadable if they were saved while the project was running
Transparency now functional for MD3 models and for KML models with model skin off
Sliders and monitors only update if something changes, making execution much faster
Stamp now stamps a circle the size of the agent
"Stamp patch" added to stamp just the patch
Automatic conversion of "stamp" to "stamp patch" for older projects
Added "set clock" block
Added "reset random" block 
Collision blocks appear in Collisions drawer now
"patch height" now gives the exact height at agent's exact location, rather than average height of that patch
Saved agents no longer decrease the number of agents available in the program
Improved error reporting for projects that don't load correctly
"New project" now results in a screen looking like when the program first loads
Removed "test" sound
Updated Terrain drawer to a better order
Projects still load even if shapes or sounds they depend on can't be found
Fixed bug where if agents died in a procedure after yield, newly-hatched agents would die immediately
Added Taj and Stata buildings to models folder
Special characters in variable, procedure, and breed names no longer make files unloadable
Made splash screen appear on Macs
Levels no longer fail to load if opening a file via double-click
Added "inc score" and "dec score" blocks to make score just like any other shared number variable
Removed unused Network menu
Added blocks to hide and show skybox
Added clear blocks for individual breeds
Height of patches is now displayed along with X and Y coordinates in terrain editing mode
Color blocks are now closer to the right colors
Added "random color" block
Added "random shape" block
Agents can now call more than one procedure in setup[do] blocks
Turtles with pens down now color the terrain even if moved via "setx" "sety" etc.
TNG will now run even if it does not have write access to its folder
Fail more gracefully if encountering unknown commands (allowing us to run projects from future versions)

Version 1.0 -> 1.2
*Levels - users can create multiple levels and switch between them via new blocks in Terrain drawer
*Agents save with project files
Added "hide patches" and "hide miniview" blocks, both callable from agent or setup code
Spaceland doesn't steal focus when turned blocks off from blocks window
Modified terrain format to allow for loading of terrains saved in future versions
Corrected crashes related to block highlighting
Added shapes for moon, earth, and cloudy earth
Added editable sockets for things like graph blocks
Fixed socket synchronization problem
Graphs and tables update rather than being recreated when blocks are attached or removed
Infix (math) blocks draw more nicely - almost correctly except when containing very complicated blocks
Collision and runtime blocks' socket labels update correctly

Other things in Version 1:
*Added "yield" block which allows an agent to momentarily pause execution long enough to be displayed
Renamed "String" blocks to "Text"
Improved copy and paste
Only left mouse button can be used to drag blocks
Added "emergency stop" button next to speed slider that interupts current execution
drastically cut CPU usage when nothing is running or when Spaceland does not have keyboard focus
Added list functionality
Added "reset camera" button in Spaceland
Existing subsets are no longer wiped out when you click "edit subsets" again
Improved behavior when clicking on runtime buttons - they now highlight immediately if turning them on
Show X and Y coordinates in status bar when editing terrain
Replaced "Globals" page with "Everyone" page
Added "Collisions" page


Beta 1.1 -> Version 1 

Drawers
-updated animation
-new organization
-new colors
-Subsets (saves with project file)

Workspace
-Improvements to typeblocking 
-search is smarter in result order
-results can be told apart by sockets
-tooltips
-show/hide mini view
-click and drag in canvas
-Shape Images on Breed Pages/minimap
-fixed copy paste bug
-introduced zooming

Order of Execution
-Collisions and graphs don't run when forever blocks aren't running
-In collisions, top agent executes first, bottom second, but if one dies the other still executes

Running Projects
-Blocks highlight much more quickly
-an "emergency stop" button has been added which immediately halts execution

New Blocks
-more traits of other turtles (Added missing -of blocks)
-wall ahead?, slope ahead
-switch block expands
-Yield -- (BUG: shouldn't be able to ask agent, so don't try to or it'll break)
-recolored and reorganized drawers and blocks

Edit Breeds
-redesigned interface
-bug fixes

New Shapes
-pac-man
-carrot
-bunny
-fire
-fireman

Saving Comments
-resize is saved
-label appears on block

Runtime Window
-Saving Locations of Runtime Blocks
-Runtime Blocks in Scroll Pane
-new skybox
-Runtime Recorders
-Tables, save data
-Save line graph data
-line graph colors and thickness changed
-Fixed bar graphs, Save Bar Graph
-Clear graph

Procedures
-Collapsing
-Output blocks are back and almost work (call blocks in drawers load without proper plugs, requiring you to detach and reconnect output blocks to those procedures for proper behavior)
