Change Log

0.4c Oct 2026

• Extension Management:
  • Choose no extension or one of Micro:bit, SQL, Micromelon and Gaming per program.
  • The toolbox shows core blocks and only the selected extension.
  • Switching confirms removal of extension blocks while preserving core blocks; Undo restores the complete previous program.
  • Extension selection is saved in JSON. Older programs infer their extension; conflicting files require an explicit keep-one choice.
  • Conflicting pasted groups are rejected without changing the program.
• Searchable help system gives user support for all blocks.
• Implemented Pseudocode grammar is documented for all core blocks.

0.4b Sep 2026

• Simplification of user interface for sub-program blocks:
  • One New subprogram action with a creation-time Return required? choice.
  • Definitions show BEGIN name(parameters), optional RETURNS type, and END name.
  • Existing typed variables, parameter mutator, calls and saved symbol data remain compatible.

0.4a Sep 2026

• Unified symbol table to implement simple/advanced scoping schemes:
