What's new in 3.0?
May 3, 2026
Bug Fixes
Copying the code or console with buttons would not actually copy it, now it does
Ctrl/Cmd + A to clear the console would select all the code, now the keybind is Ctrl/Cmd + Q
The button name for the 2.1 Update article was "Check out the OnlineCode 2.0 Changelog" which is now "Check out the OnlineCode 2.1 Changelog"
Location Changes
Moved "Coding in OnlineCode" (https://sites.google.com/view/onlinecode/code) to https://sites.google.com/view/onlinecode/home/code
Languages
Added Plaintext
Plaintext is a simple notepad, nothing really special here.
Added BrainF
The BrainF language, very hard to use and learn. This language uses no text, just +, >, {}, and [].
