This release contains breaking ABI changes, API should remain compatible with older verisons.

What's Changed

• top-level DSL methods accepting lambdas were marked with kotlin conracts

    contract {
        callsInPlace(block, InvocationKind.EXACTLY_ONCE)
    }

this allows to initialise variables in lambdas in some cases without using lateinit var. For this change I had to split some of them (taking nullable lambda) to two separate methods (with non-nullable lambda and without it at all). I expect that you don't have to change your code or imports, but this is ABI breaking change.

• DataExtractor for DataState now will be called in case of implicit state activation, allowing to intercept data from event in such case. See isImplicitActivation flag in DataExtractor::extract method. This is also ABI breaking change.

• Added new MutableDataState state type. It acts exactly the same way like DataState before, but allows to mutate the data manually with setData method. This is less strict, but more flexible then DataState which data can be updated only by transition.

• Add native platforms support. This adds new output artefacts for linuxX64, mingwX64, macosX64 and macosarm64

• Update all used libraries and tools to actual versions. Updated Kotlin to 2.2.0, JDK to build project to 21.

• Updated publication process to maven central as the old one was deprecated by Sonatype, please open an Issue if you having some problems with getting artefacts from maven repo.

• Add MutableDataState by @nsk90 in https://github.com/KStateMachine/kstatemachine/pull/119
