Change Log

[0.4.4] - 2024-04-11

• Update Bouncy Castle to 1.78 to address various CVEs.

[0.4.3] - 2024-03-12

• Update Clojure dependency to 1.11.2 to address CVE-2024-22871.

[0.4.2] - 2024-02-29

• Update Pedestal dependency to 0.6.3.
• Update Jetty http2-server dependency to 9.4.54 to address CVEs.

[0.4.1] - 2024-01-25

• Fix a number of bugs associated with Statement generation:
  • Fix places where :definition was used when :activityDefinition was supposed to be used in the code, causing Activities not to be associated with their respective Activity Types.
  • Stringify keys for map values of any, all, and none in Statement Template rules.
• Update Cheshire dependency to 5.12.0.

[0.4.0] - 2024-01-03

• Change alignments inputs to models inputs that incorporate additional temporal properties.
• Make models an array in which the user can apply different personae to.
• Separate alignments by component types: verbs, activities, activityTypes, templates, patterns, and objectOverrides.
• The new temporal properties are as follows:
  • bounds: the time intervals in which a particular Pattern's or Template's statements are allowed to generate in.
  • boundRestarts: which Pattern or Template should repeat if a bound is exceeded.
  • periods: the frequency in which a Pattern's or Template's statements are generated.
• Make repeatMax a model property for Patterns instead of a hardcoded constant.
• Rework the CLI so that subcommands go in the front, not the end, of the top-level command.

[0.3.2] - 2023-10-03

• Update server Jetty dependencies to v9.4.52 to address CVEs.

[0.3.1] - 2023-07-24

• Fix bug where the same any and all values are chosen within the same generated sequence.

[0.3.0] - 2023-07-13

• Major reworking and refactoring of internal namespaces; some notable changes:
  • Completely reworked the structure of the datasim.xapi directory
  • Removed the datasim.json directory in favor of using the pathetic and schemer libraries
  • Move timestamp and random namespaces to a new datasim.math namespace
  • Change input functions to use multimethods instead of records
  • Refactored CLI and server namespaces
• Add top-level API functions to the datasim namespace:
  • read-input that wraps input/from-location for JSON input maps
  • generate-seq and generate-map for synchronous statement sequence and skeleton map gen, respectively
  • generate-seq-async and generate-map-async for async versions of the above
• Changes to Statement generation:
  • Template Context Activities and Attachment Usage Type properties are now supported
  • Performs basic "statement healing" by filling in required properties after Template rule/property application; verbs and activities are healed mainly by selecting values from the profile cosmos, while other objects are healed using spec generation
  • Supports complected JSONPath locations and selectors, e.g. those that use the pipe operator
  • Removes object rules and properties if an object override is present, preventing redundant rule application and potential clashes
  • Rules with recommended presence now have their values be applied/generated
  • Fix a bug where ARMA squences, which form the basis of statement generation, were incorrectly generated
  • Precompile Statement Template properties and rules before statement generation, as an optimization measure.

For more information on all changes, see Pull Requests #89, #93 to #97, #98 to #103, and #106 to #109.
