The xar package now has the command "claimtrophies". When this command is run, you gain a Steam achievement for every trophy that your player has already collected. Note that you run the command by opening the console "press ~" then type "claimtrophies" and hit enter.

You can now create the file "WorldNodes/xar/xar_block_overrides.txt". This file lists xar nodes that are replaced by Lua block scripts.

Now any package that depends on the xar package can have the __main functions of its Lua block scripts create xar blocks.

Now the __main functions of block scripts can use the built in xar chunk generation code to generate them.

You can now enable and disable anisotropic filtering. Use the variable "engine.render.anisotropic_filtering".

There is now a command called "save passive". This will do nothing if automatic saving is disabled. If automatic saving is enabled, this command will save the game only if at least five minutes have passed since the last save or if there are 10,000 chunks that need to be saved. "Constant saving" mode has been replaced with "automatic saving", using the "save passive" command described above. That is, "save passive" is called whenever the player is in a menu.

Hardcore mode works differently. Instead of saving the game constantly, it uses "automatic saving". However, if the player is in hardcore mode and they either try to create a new game, load a game, or exit the game, then the game will be forcibly saved.

Now there is no rendering of "special basic entities" by the engine. For example, green shrink rings are now rendered in Lua code instead of being rendered in a hard coded way by the engine.

Packages can now render weapons being held by the player. This is accomplished by having Lua code render meshes and modify the OpenGL matrix stack. Indeed, from Lua code you can now render objects in the world.

The music system now loads music in a separate thread.

The system command "help" and the xar package command "help2" have been merged into one.
