Change Log for the BPjs Library.

2023-09

• :sparkles: EventSets now have an except method, that allows removal of events from the set. e.g. allMotionEvents.except(moveDownEvent). (#218)
• :arrow_up: Improved error messages when composing event sets.

2023-08

• :part_alternation_mark: BPjsCodeEvaluationException is now have one general constructor for all rhino exception(#200)
• :bug: BProgramRunnerListenerAdapter is now doing what adapters should do (create empty implementation for abstract classes and interfaces) and does not print on errors anymore. (#119).

2023-06

• :arrow_up: Printouts and toStrings of JavaScript compound values (e.g. arrays) adhere to normative JavaScript style. That is, no more [JS_Array 1,2,3], just [1,2,3]. Java objects still retain their J_ prefix.(#213).

2023-05

• :arrow_up: Upgraded dependencies.
• :arrow_up: MapProxy's seed is now protected, so client code can use it directly (#206).
• :sparkles: Dedicated exceptions for calling bp.sync and bp.thread outside of a bthread. (#195, #203)
• :part_alternation_mark: BpLog is now an interface, and it's implementation can be changed by calling BProgram.setLogger. (#208)
• :sparkles: BPjs' version is now available at runtime, using BPjs.getVersion(). (#136)
• :sparkles: BPjs' logger is now is now supporting bp.log.error. (#175)

Earlier Changes

Legend:

• :arrows_counterclockwise: Change
• :sparkles: New feature
• :tada: New feature, but more exciting
• :part_alternation_mark: Refactor (turns out this sign is called "part alternation mark" and not "weird 'M'", so it fits).
• :put_litter_in_its_place: Deprecation
• :arrow_up: Upgrade
• :bug: Bug fix
