JetBrains has released the second Early Access Program (EAP) version for MPS 2025.3, which introduces several notable improvements, including a complete overhaul of the JavaDoc language to use jetbrains.mps.lang.text for text representation and editing. This change allows for a consistent editing experience, enabling text styling and improved copy-paste functionality across different MPS languages. The update also includes enhancements to generator plans, replacing the experimental fork functionality with PlanContribution, and adding mechanisms for branch model denotation and conditional activation based on specified parameters. Additionally, a new "Paste as JavaDoc" action has been introduced in BaseLanguage, facilitating easy pasting of JavaDoc code with proper parsing and reference resolution. The release also improves the creation of new elements in the Project view through enhanced keyboard shortcuts, offering a more efficient user experience without the need for a mouse.
