Runners

Gradle Plugin

• Mark tasks as not compatible with Gradle configuration cache, second try (https://github.com/Kotlin/dokka/pull/3438). Thanks to @​3flex for noticing and fixing the problem!

Maven Plugin

• Fixed dokka:help being absent (https://github.com/Kotlin/dokka/issues/3035). Thanks to @​aSemy!
• Fixed the source links configuration not working (https://github.com/Kotlin/dokka/pull/3046). Thanks to @​freya022 for fixing this one!

CLI runner

• Allow using relative paths in the sourceRoots configuration option (https://github.com/Kotlin/dokka/issues/2571)

Plugin API

• Provide an extension point to customize the rendering of code blocks in HTML format (https://github.com/Kotlin/dokka/issues/3244)

Other:

• Make sure wasm-js and wasm-wasi targets introduced in Kotlin 1.9.20 are supported (https://github.com/Kotlin/dokka/issues/3310)

• Bump dependencies to the latest versions (https://github.com/Kotlin/dokka/pull/3231, https://github.com/Kotlin/dokka/pull/3206, https://github.com/Kotlin/dokka/pull/3204)
