Kotlin/dokka (org.jetbrains.dokka:android-documentation-plugin)

v2.1.0: 2.1.0

Dokka 2.1.0 focuses on stabilizing experimental features, supporting new Kotlin language features, and improving the user experience. Key highlights include:

• Dokka Gradle Plugin v2 is enabled by default!
• K2 Analysis is enabled by default!
• Support for Context parameters and Nested typealiases
• HTML format refinement: better accessibility and consistency across all components

More details about each of the changes below. See Dokka 2.1.0 milestone for the list of all changes.

Dokka's Gradle plugin v2 is enabled by default!

Please check the migration guide for the update procedure

Dokka 2.0.0 introduced a significantly improved Gradle plugin v2, and with Dokka 2.1.0 it is now enabled by default!
As a result, all types and Gradle tasks related to Dokka Gradle plugin v1 are deprecated and will be removed in future releases.
Running Gradle tasks related to Dokka Gradle plugin v1 will result in an error during execution.

Starting from this release, the minimum supported Gradle version is 7.6.3.

Other fixes and improvements

• Update Gradle Properties types to be non-nullable (#​4136)
• Update displayName convention for DokkaSourceSets (#​4142)
• Update olderVersionsDir to be an optional input. (#​4155)
• Add lifecycle tasks for generating formats (#​4141)
• Use project name as default modulePath for root project to avoid clashing outputs during aggregation (#​4158)
• Remove Dokka debug config file from task outputs (#​3961)
• Remove V2EnabledWithHelpers warning & info message (#​4206)

Dokka's K2 analysis is enabled by default!

Dokka 2.1.0fixes the most problematic issues with K2 analysis and makes it enabled by default!
In addition to this, Dokka 2.1.0with K2 analysis introduces support for context parameters and nested typealiases!

Dokka's K2 analysis leverages Kotlin's K2 compiler frontend for analysing code and uses the same shared Analysis API, which is used in IntelliJ IDEA’s K2 mode.
The output with K2 analysis should mostly match that of K1 analysis, but there may be minor differences.

If you previously opted in to Dokka's K2 analysis, remove org.jetbrains.dokka.experimental.tryK2 from your project's gradle.properties file.
Dokka's K1 analysis is still available, but it is deprecated and will be removed in future releases.
We would greatly appreciate your feedback, if there is something that is blocking you from migrating to K2 analysis!

Other fixes and improvements

• Fix merging of implicit expect/actual with a single declaration (#​4016)

• Fix override modifier for generic functions (#​4126)
• Add a receiver to accessor DRI (#​4122)

HTML format refinement

Dokka 2.1.0 introduces a number of design improvements to the HTML output.
Many UI elements (listed below) now feature more consistent spacing, better contrast, and improved overall accessibility.

Highlights:

• Improved accessibility of the Search popup and Table of Contents and Tabs
• Resizable Table of Contents
• Customizable spacing in the Table of Contents via a new set of CSS variables (See #​4184 for details)

In addition, the structure of the templates has been slightly modified. If you're using custom templates, the easiest way to migrate is to update your templates based on the latest default templates.
For example, to enable the resizable Table of Contents, you need to add a <div id="resizer"> element and add [data-item-type] attributes to container elements. For implementation details, see the template reference.

Updated UI Elements:

• Main layout
• Table of Contents
• Footer
• Search popup
• Code areas and code blocks
• Links
• Tooltips
• Tables
• Markdown tables

Notable improvements

• Performance:
  • Cache packages field, which is used by DefaultExternalLocationProvider.resolve (#​4009)
  • Cache DisplaySourceSet as it's stored a lot inside of ContentPages (#​4008)
  • Significantly improves the performance when working with PackageList (#​4198)
• Support a newline inside link text (#​3661)
• Resolve references to quoted names (#​3356)
• Update jackson to 2.15.3, which doesn't have known vulnerabilities (#​4189)
• Make Dokka safe for Jackson updates in user projects (#​4193)
