				---------------------------

This file contains brief notes about each of the released
versions of the PyTAS Simulator.


Version 2017-12-05-23-53-23:
	- Very preliminary alpha version which bundles 2D and 3D functionality.
	  Likely to have many bugs!

Version 2017-12-10-13-38-34:
	- A few bug fixes
	- Added creation of lookup tables of glues and tile sides to speed up
	  creation of cache and assembly

Version 2017-12-19-09-37-45:
	- Big performance improvements for 2D
	- Allow centering of camera on specified coordinates in 3D
	- Allow reporting of detected nondeterminism and breaking on it

Version 2017-12-20-11-35-47:
	- Added the ability to set breakpoints based on (1) the number of tiles
	  in the assembly, (2) the addition of a tile of a specified type, or
	  (3) the addition of a tile to a location matching a given pattern

Version 2017-12-20-18-03-21:
	- Improvements to mouse-over behavior in 3D mode
	- Added ability to add new tile types and tile placements to existing
	  systems

Version 2018-01-16-00-12-03:
	- Many bug fixes and feature additions, including addition of a tile type
	  editor window and the ability to manually add and remove tiles in the
          simulation window to allow manual creation of seeds.

Version 2018-01-16-01-00-47:
	- Updated README.txt with current installation instructions
	- Turned off reporting of nondeterminism by default until the reporting
	  can be made more thread safe

Version 2018-01-17-18-03-03:
	- a few bug fixes for running on Ubuntu

Version 2018-07-11-10-03-22:
	- A preliminary beta release with many bug fixes and optimizations for large 3D simulations


Version 2019-07-01-18-29-43:
	- A few minor bug fixes

Version 2019-07-01-22-57-16:
	- A few hack-ish fixes for drawing tiles on OSX, for which the wxWidgets library seems to have some bugs

Version 2019-07-01-23-30-30:
	- Fixed packagine errors

Version 2019-07-01-23-55-48:
	- Yet more packaging fixes

Version 2019-07-02-15-28-49:
	- A bit of a hack to fix the tile type editor. A better designed fix needs to be incorporated since this puts a dependency in the SimulatorFramework on PyTAS.


Version 2019-07-02-19-15-53:
	- Allow pasting of assembly definitions into simulation window

Version 2020-07-28-18-11-51:
	- Upgraded to Python3, many bug fixes. The main known issue with this release is poor drawing of assemblies with > 100,000 tiles.

Version 2020-08-04-11-28-55:
	- Fixed bugs to allow for saving of tile set in the editor and placing of tiles in an assembly. There are still several related bugs though. This is just an intermediate version (hopefully).


Version 2021-10-20-14-50-02:
	- A few bug fixes and implemented the ability to save images of assemblies.


Version 2024-02-28-09-02-23:
	- Several fixes to be compatible with latest wxPython
	- Quite a few partially implemented new features that are not documented yet
