 # Changelog
 
-[0.4.0]
-
-- First pass getting compiled IC10 to output along side the Slang source code
-  - IC10 side is currently not scrollable, and text might be cut off from the bottom,
-    requiring newlines to be added to the bottom of the Slang source if needed
-
 [0.3.4]
 
 - Added support for `loadReagent`, which maps to the `lr` IC10 instruction

 [*] [b]Temperature Literals:[/b] Don't worry about converting Celsius to Kelvin anymore. Define your temperatures as whatever you want and append the proper suffix at the end (ex. 20c, 68f, 293.15k)

-[*] [b]Stack Access:[/b] Direct stack memory access is disabled to prevent conflicts with the compiler's internal memory management. A workaround is being planned.

 [*] [b]Documentation:[/b] In-game tooltips for syscalls (like load, set) are WIP. Check the "Slang" entry in the Stationpedia (F1) for help.

 [h2]Planned Features[/h2]
 [list]
+[*] Side-by-side view: Slang vs. Compiled IC10.
+[*] Compiler optimizations (dead code elimination, smarter register allocation).
 [*] Enhanced LSP features (Autocomplete, Go to Definition).
 [*] Full feature parity with all IC10 instructions.
 [*] Tutorials and beginner script examples.
