## v1.0.0-beta.7 - 2025-10-16

### Added

- Added `once` function to listen to the next event only once.

## v1.0.0-beta.6 - 2025-10-16

### Changed

- **BREAKING**: Changed `superstate.State` to `superstate.Def` to better reflect its purpose and free up the `State` name for specific instance state type.

### Added

- Added `superstate.State` type to represent a specific instance state.

## v1.0.0-beta.5 - 2025-10-16

### Changed

- **BREAKING**: Renamed `State` type to `superstate.Def` to avoid conflicts with other libraries.

### Added

- Added `superstate` namespace to access helper types, i.e., `superstate.State` and `superstate.Instance`.

## v1.0.0-beta.4 - 2024-05-07

### Fixed

- Fixed previously incorrecly published package.

## v1.0.0-beta.3 - 2024-05-07

### Changed

- **BREAKING**: Changed the send API from string-based to proxy-based: `.send("event()")` -> `.send.event()`. Condition is now a separate argument: `.send.event("condition")`. To send substate events, use the substate name as a prefix: `.send.os.event()`.

- **BREAKING**: The final state to parent transition definition now requires including the substate name into the source state: `.sub("os", osState, "terminated -> shutdown() -> off")` -> `.sub("os", osState, "os.terminated -> shutdown() -> off"))`.

### Added

- Added contexts support. [See README](https://github.com/kossnocorp/superstate#contexts).

## v1.0.0-beta.2 - 2024-04-11

### Added

- Added `superstate/mermaid` submodule with `toMermaid` function to covert a statechart to Mermaid format. [See README](https://github.com/kossnocorp/superstate#mermaid).

### Fixed

- Fixed factory's `sub` property types.

- Fixed `exports` in `package.json`

## v1.0.0-beta.1 - 2024-04-10
