What changed

OSL began as the scripting language inside originOS. That runtime supplied browser windows, camera access, simulated input, inter-window messages, permissions, global UI state, and its own file model.

The current OSL compiler builds standalone native programs. It does not include the originOS desktop environment, so those APIs do not carry over simply because the language syntax looks similar.

What changed

originOS feature	Current OSL replacement
Browser window commands	std:window or std:raylib
originOS filesystem	std:fs
Browser HTTP and WebSocket methods	std:requests and std:ws
Desktop notifications	std:notify
Embedded sound	std:sound
Running Lua	std:lua
originOS save database	std:save or std:db

Camera access, simulated system input, originOS permissions, and inter-window desktop messages have no direct compiler equivalent.

What remains here

The pages in this section preserve a small amount of old syntax for people reading historical originOS programs. They are not part of the current language guide and should not be used as a source for new OSL code.
