8 Commits • 2 Features
May 1, 2025In May 2025, delivered key Isabelle integration enhancements, reliability fixes for SMT action undo, and code quality improvements that collectively broaden compatibility, stabilize proof states, and simplify maintenance. Specifically, Isabelle support now covers Isabelle2023/Isabelle2024, with a new IsabelleSupportState enum, improved user-facing messages, and directory-based settings selection; SMT ApplyAction undo pruning was fixed to preserve proof integrity; and SMT proof actions were renamed and centralized with improved undo handling, plus formatting and translation cleanups to reduce maintenance overhead and improve readability.
