0.9.5

• Many API changes.

0.9.4

• Many API changes.
• Fix for Dart 2.0.

0.9.1

• Continued the API normalization work; removed add*, minus* where it did not add any performance gains. Time plus\minus --> add\subtract, added an abs method.
• LocalDateTime\LocalDate\LocalTime added periodUntil\periodSince, removed difference, made static method difference from differenceBetween
  • same with OffsetDateTime except time vs period

0.9.0

• Added a LocalDate.today(), LocalDateTime.now(), LocalTime.timeOfToday() constructors.
• Refined Local* api's to be more like dart:core.DateTime
  • Did the same with Instant, ZonedDateTime, OffsetDateTime, Offset, Period

0.8.5

• Constructor is now LocalDateTime.localDateAtTime(LocalDate, LocalTime)
• Formatted much API Documentation.
• Removed operator based dynamic dispatch from all operator - methods. Many times it makes sense to for example, subtract to do this, end_date - start_date = delta_time and to do this, end_date - delta_time = start_date but only makes sense for addition to do this, start_date + delta_time = end_date, you'd never do this, start_date + end_date = delta_time (doesn't really make sense) -- so, the operator - methods have been defaulted to do the same operation as the operator + methods. If Dart 3 gets compile time dispatch, these other methods will be re-enabled.

0.8.4

• Bugfix for Flutter.

0.8.3

• Removed all the Period.from* constructors, added a named constructor, constructor const Period({this.years: 0, this.months: 0, this.weeks: 0, this.days: 0, this.hours: 0, this.minutes: 0, this.seconds: 0, this.milliseconds: 0, this.microseconds: 0, this.nanoseconds: 0}); instead of Period.fromYears(int years).
• Moved collection: "^1.14.10" to collection: "^1.14.6" in order to satisfy Flutter unit testing requirements. time_machine can not be unit tested directly in flutter because of a breaking change between matcher: ^0.12.2+1 and matcher: 0.12.3 with regards to TypeMatcher going from an abstract non-instanced class to a regular instanced class. See flutter_test/pubspec.yaml.

0.8.2

• Instant constructors condensed: Instant.utc, Instant, Instant.julianDate, Instant.dateTime, Instant.epochTime
• Removed from from a lot of constructors, heavily redundant (well, maybe not so redundant with the loss of new)
• Added a timeZone override to TimeMachine.init() so you can supply a local DateTimeZone to Flutter if you something like flutter_native_timezone loaded as well.
• CalendarSystem cleaned up.

0.8.0

• Dart 2.0 ready to go. TimeMachine 0.7.1 was the last version that will work on Dart 1.24.3.
  • Added a lot of BigInt code, there is no going back now. Added Time.canNanosecondsBeInteger, Time.fromBigIntNanoseconds(), Time.totalNanosecondsAsBigInt
  • The Dart2JS example compiled sized dropped by about 11%.

0.7.1

• No more dart analysis errors on 1.24.3.
  • Refactored away the port-helper KeyValuePair and OutBox classes.
  • Fixed (or annotated) all unused variables, fields, elements, and imports issues.

0.7.0

• Updated LocalDateTime.at() to reflect the LocalTime constructor update.
  • note: renamed LocalDateTime.at() to LocalDateTime() and then renamed the original LocalDateTime(LocalDate, LocalTime) to LocalDateTime.combine(LocalDate, LocalTime)
• Added Badi, Coptic, Hebrew, Islamic, Persian, and UmAlQura calendars.
  • Tested sat on VM/JS.

0.6.0

• Removed the concept of ticks and replaced all the functions with microseconds; Rational: the only place ticks shows up as a concept is here https://api.dartlang.org/stable/1.24.3/dart-core/Stopwatch/elapsedTicks.html; ticks from .NET-land is 100 nanosecond unit of time; ticks from dart is based on a dynamic frequency number, on my machines it's 1 us in the browser and 1 ns in the vm.
• Simplified LocalTime constructors; now one generic + one that takes a Time sinceMidnight. (from 7 initial)
• Added microsecond/millisecond logic around DateTime conversions wrt Platform
• Cleaned up Offset - removed subsecond constructors, since Offset can't be subsecond, and made the fromSeconds constructor the default constructor.

0.5.0

• Major API Changes (Sorry!)
• Span (denotatively and connotatively wrong) to Time (to just connotatively wrong)
• text_patterns moved to time_machine_text_patterns from time_machine global (still thinking about what things should be not visible by default)

0.4.1

• Missed a logging reference (took it out).

0.4

• DartVM mirrors based unit tests can now be used to compute DartWeb non-mirrors based unit tests. All web-compatible unit tests are now passing, and TimeMachine is safe for use when compiling via Dart2JS.

0.3

• Coalesced imports into a single import and all @internal functionality is now hidden.

0.2.2

• Fixed bug introduced in 0.2.1; (Conditional Imports are hard); dart.library.js seems to evaluate to false in DDC stable. Put back as dart.library.html.

0.2.1

• Fixed bug introduced in 0.2.0 causing TimeMachine.Initialize() to not fully await.

0.2.0

• No more specific imports for your platform. Flutter usage was streamlined significantly.

0.1.1

• Broke some things while making this work on many platforms. Fixed them (still need to do unit tests on js).

0.1.0

• Made some changes to try and less confuse Pana.

0.0.4

• Now works on Flutter, Web, and VM!

0.0.2

• Many things have been Dartified. Constructors consolidated, names are lowercased, @private usage heavily reduced.

0.0.1

• Initial version.
