- Permit state reentry from dynamic transitions #565
- This is a change in behavior from v5.15.0 (see #544); this version restores the previous behavior for
PermitDynamicthat allows reentry; if reentry is not the desired behavior, consider using a guard condition withPermitDynamicIf.
- This is a change in behavior from v5.15.0 (see #544); this version restores the previous behavior for
- Remove getDestination, and use Destination property instead (internal refactor) #575
- Add overloads to
FireAsyncto support parameterized trigger arguments #570 - Add overloads to
CanFireto support parameterized trigger arguments #574
- Prevent
NullReferenceExceptionin theInvocationInfoclass #566
- Updated net6.0 build target to net8.0 #551
- New abstract method,
GetInitialTransition, added toGraphStyleBaseto remove DOT graph implementation fromStateGraph#557- Classes that are derived from
GraphStyleBaseand are being migrated from an earlier release of Stateless will need to implement this method.
- Classes that are derived from

RetainSynchronizationContextproperty #519 - Update example apps to
net6.0#520 - Bump solution Visual Studio version to 2022 #526

InvalidOperationExceptionthrown from call toFireAsync#532- Added missing guard function parameter support from
InternalTransitionAsyncIf#530 - Using
PermitIfon a state with substates leads to reentry #544
- Add method to get permitted triggers with parameter information #494
- Fix incorrect initial state in dotgraph after trigger fired #495

- Stateless.Tests -> .NET 6 #484
- Update Readme regarding state machine events #488
- Typo in summary comment of class UmlDotGraph #471

- Inconsistency in sync/async statemachine execution #444
- Added support for spaces in state/trigger names in Graphviz node graphs by wrapping them in escaped quotes #447
Re-releasing 5.2.0 as v5.10.1. The version number was accidentally set to 5.10 when creating the 5.2 release. Version 5.10.0 is now listed as the newest, since it has the highest version number. 5.2.0 and 5.10.0 are identical.
- Added support for net50
- Only run tests under net50
- Non-code change: Switch to using Github Actions
- Fixed the bug "IgnoreIf Guard description is raised when PermitReentryIf Guard Fails". #422
- Fixed bug "When adding .PermitDynamicIf, call .PermitTriggers throw NullReferenceException" #416
- Fixed nullReferenceException when getting permitted triggers on a dynamic transition. #413
- Fixed OnTransitionCompletedEvent, it now has the correct Destination state when there is an initial transition. #413
- Added support for new OnTransitionCompletedEvent, which is run after all OnExit / OnEntry methods have run #394
- Fixed spelling errors
- Fixed analyser warnings (mostly null checks)
- Added CLSCompliant attribute, which went missing in November 2019 #401
- Fixed Unmet guard collection not set by OnUnhandledTrigger if transition guard of substate fails #398 (Thanks to the awesome DeepakParamkusam)
- Fixed ambiguos guard function call when trigger is a state #380
- Fixed wrong onTransitionEvent ordering in Async firing [#372]
- Inverted if (_firingMode.Equals(FiringMode.Immediate) into if (FiringMode.Immediate.Equals(_firingMode) to avoid VerificationException when including assembly AllowPartiallyTrustedCallers #365.
- Added missing possible destination states to all PermitDynamic and PermitDynamicIf, see issue #305.
- Fixed trigger execution order issue if there are uncaught exceptions. Ref issue #267
- Fixed issue #272 and #275. Triggers with no parameters threw exceptions when checking if they could be fired, or retrieved with GetPermittedTriggers.
- Added missing initial transition, see PR #286.
- Activate and deactivate actions only runs on manual call to Activate / Deactivate. This breaks the v4.4 implementation, where activate/deactivate actions are run on every state transition.
- PR #348 Added trigger parameters to OnTransitioned event
- #342 StateMutator is called multiple times with the same state
