  • Review Information

There have been well over 1500 commits to Epsilon since 1.5, with many major changes, improvements, over 70 bug fixes, optimisations and new features in almost every aspect. A summary of the most prominent changes:

  • Major refactoring / tidying up of code, leading to improvements in performance and extensibility.
  • Short-circuiting mode for EVL: stop execution when any constraint is violated.
  • Parallel execution capabilities for EOL declarative operations, EVL, EGX, ECL and EPL.
  • EVL ConstraintTrace optimisation (enabled by default): only adds targets of dependencies to the trace.
  • Support for native lambda expressions, allowing Java functional interfaces to be invoked using EOL/OCL/JavaScript lambda syntax.
  • Common FunctionalInterface type constructors, e.g. runnable, supplier, function, consumer.
  • Ternary operator which works anywhere an expression is expected.
  • Thread-safe types: ConcurrentBag, ConcurrentMap, ConcurrentSet.
  • RefactoredIPropertyGetter / IPropertySetter interfaces to be stateless.
  • New EOL operations: count - an optimised select.(...).size() and NMatch - a short-circuiting way to do select.(...).size() [size comparison] [integer literal].
  • [NEW] Picto: infrastructure for orchestrating model visualisation through lazy model-to-text transformations.
  • [NEW] Flexmi: Allows for construction of EMF models using XML with shorthand notation based on string similarity.
  • Numerous improvements and additions to the Simulink EMC driver.
  • Major improvements to dependency management, feature.xml files, releng etc. - relying on Orbit where possible for third-party dependencies.
  • Removed Concordance as it's no longer maintained or useful (supercedeed by Hawk)
  • An API for easily running Epsilon programs standalone, with support for fine-grained rule profiling (i.e. more detailed than is available from the standard Epsilon profiler), parallel execution, repeating etc. - useful for testing, benchmarking and a concise way for users to run Epsilon without requiring deep knowledge of the internal structure.
  • Setup files for Oomph.
  • Self-contained P2 update site (we were using old-style pre-P2 "Update Manager" sites before).
