    May 12, 2017

    ๐Ÿš€ Release Notes

    ๐Ÿš€ This release introduces limited and experimental support for event tree analysis.
    Only necessary and sufficient functionalities are implemented
    to allow the most common and basic analysis.

    • CCF level numbers are optional.
    • CCF factors can be declared in any order.
    • Multiple 'model-data' containers are allowed within a single 'opsa-mef' element.

    - Gate formulas can have literal constant args (true, false) instead of house-events.

    Interval-based expression sample domain validation (instead of min-max)

    ๐Ÿ–จ Print line numbers in XML schema validation error messages

    โš  Report warning messages with XML attributes in the results-layer instead of XML elements.

    February 12, 2017

    ๐Ÿš€ Release Notes

    Analysis and post-analysis facilities work directly with a ZBDD-based product container
    without paying memory or speed overhead of converting ZBDD into other data structures.

    Major Changes

    • ZBDD as a fault tree analysis result (product/cut-set) container (#159)
      • Qualitative analysis speedup from 10% to 5x (the more the products, the bigger the effect)
      • Memory consumption decreases by 1.5 - 4x (noticeable only for million or more products)
      • Iteration over products is ~2x slower (graph walk vs. sequential array of products)
      • Quantitative analysis with approximations (rare-event, MCUB) is 2 - 10x slower
        (the fewer the products, the worse the effect)

    Minor Changes

    • ๐Ÿ Package for Windows (#157)
    • ๐ŸŽ Package for macOS (#158)
    • ๐Ÿ‘ HTTPS support for the website
