Snapshot 2020-07-28

This release is based on MPS 2020.1.2 and brings many small improvements accross different DSLs.

• improvements of STPA language (enable multiple UCAs for an action, add names to UCAs to be referenceable e.g. from requirements)
• improvements of GSN languages (reworked the implementation of AwayGoals, fixes in the textual projection & diagramatic editor)
• improvements of the Spin integration (enhanced the subset of Promela that we cover)
• enable the possibility to attach attributes to requirements (traces to UCA from STPA)
• enable the possibility to attach attributes to components of architecture (traces to requirements)
• improved the sequence-diagrams DSL

Snapshot 2020-05-14

Small improvements in safety languages and Spin base language.

Snapshot 2020-03-29

Most improvements addressed the safety-engineering modules of FASTEN:

• support textual and tree-like notation for the GSN models
• improvements of GSN patterns
• enabled linking of external evidence (e.g. pdf documents) to solutions
• run arbitrary external checks from specialized solutions

Additional improvements:

• new iteration to improve the modularity of arch.base and nusmv.cbd languages
  -- including migrations for existing models
• lifting of NuSMV counterexamples for CBD
• displaying of NuSMV counterexamples as MSCs
