-
CONST keyword exists.
-
Array literals exist arrays have a nicer initializer notation. probably not real literals(
source)
- SYSPARAM command (
source)
- LAYER, LFILTER, LMATRIX commands for I guess changing the display size/orientation/effects
- SUB* commands: SUBRUN, XSUBSCREEN, allow splitting the screen layout and running programs alongside the editor
+
the software keyboard is a program and uses SUBRUN (?)
- 128 MB available memory
- uploaded projects 20 MB cap (I think there's a tweet saying you can purchase more)
- HD joycon vibration is available so someone better make the ice cube demo
- screen resolution from 128x128 to 1280x720 (startup is 400x240)
- graphics pages are now 2048x2048
- a special graphics page exists at page -1 that is read-only and always returns & HFFFFFFFF
- 5 text pages
- clipping, coordinate transformation, filter and special composition for each [sprite] layer (up to 8)
- layer transforms take any 4x4 or 2D affine transformation matrix
- Layer filters are mosaic, blur, color conversion, raster deformation (h & v)
- Composition options: multiplication with color, additive with layer below, multiplicative

Along with running subprograms, state of the interpreter can be polled with ENVSTAT and there are ENV commands for working with moving resources from the main environment to sub-environments?
Console input history can be read, ENVFOCUS polls/acquires focus, and HELPINFO/HELPGET can even read from the help manual
