v1.2.0

[1.2.0] - 2026-06-08

Added

• Added AutoTransitionScheduler so auto transitions can be scheduled after an external commit boundary while preserving synchronous auto transitions by default.
• Added builder-level autoTransitionScheduler configuration for deferred auto transitions.
• Added documentation and an integration test for deferring a domain auto transition until after an intermediate state is persisted, including a Spring afterCommit example.
• Added fsm-visual-editor, a local visual FSM editor for designing finite state machine flows.
• Added .fsm.json editor project import/export, autosave, recent-project loading, and local project storage.
• Added Java and Kotlin factory code generation from visual FSM diagrams.
• Added generated state/event enums, StateContext domain DTOs, guard/action placeholders, auto transitions, timeouts, and post-action support.
• Added validation and unit coverage for editor IDs, document import normalization, storage, project API calls, layout, and Java/Kotlin generators.
• Added README documentation and visual editor GIF for the new editor workflow.

Changed

• Renamed the frontend tool to fsm-visual-editor and aligned package names, local storage keys, documentation, and UI labels.
• Updated README discovery text for Kotlin finite state machines, visual FSM editing, and Java/Kotlin code generation.
• Replaced hardcoded installation versions with a VERSION placeholder that points users to the latest Maven Central release.
• Removed maintainer-only Maven Central publishing instructions from the public README.

Fixed

• Preserved runtime TypedEvent payloads in currentTransition for event actions and post-actions.
• Preserved transition insertion order in built transition tables while isolating them from later builder mutations.
• Clarified the Spring afterCommit scheduler example to use PROPAGATION_REQUIRES_NEW for persisted auto-transition results.
• Prevented duplicate visual-editor transitions when the same states are connected twice, and surfaced matching imported duplicates in validation.
• Shortened generated PlantUML and Mermaid labels for unnamed guard/action lambdas while preserving explicit named behavior labels.
• Fixed generated duplicate event/guard/action IDs so UI-created refs remain Java/Kotlin identifier-safe.
• Rejected qualified names for generated nested domain and state types.
• Hardened .fsm.json import and saved-document loading to reject malformed array elements before normalization.

Security

• Upgraded Jackson dependencies to 2.21.1 to resolve the jackson-core async parser DoS advisory (GHSA-72hv-8253-57qq).
