## [Unreleased]
### Added
- `RedundantCoroutineScopeDetector` warns when a `androidx.lifecycle.LifecycleOwner`, `androidx.lifecycle.ViewModel`, or `android.view.View` implements or has a field assignable to `kotlinx.coroutines.CoroutineScope`.
  Existing scopes are bound to relevant lifecycle events in the system and will prevent coroutines from running past their utility.
  - `LifecycleOwner` should use `lifecycleScope`
  - `Fragment` should use `viewLifecycleOwner.lifecycleScope`,
  - `ViewModel` should use `viewModelScope`
  - `View` should use `findViewTreeLifecycleOwner()?.lifecycleScope`
- `FiniteWhenCasesDetector` warns when `else` is used as a `when` branch when the `when` subject has finite possibilities
  - This detector works best when applied to an app project with `lint.checkDependencies = true` in the app module AGP DSL.
- `ForEachFunctionDetector` reports `forEach` and `forEachIndexed` use and encourages a language for loop replacement
- `SkippedClassLocalOverrideDetector` warns when an explicit super method is called outside of the corresponding override.

### Changed
- Updated build tooling
- Treat lint warnings as errors for issues in this library
- Add spotless

## [1.1.6]
### Changed
- Java version is increased to Java 11

### Fixed
- Multiple build variants are published after upgrading gradle maven publish plugin to [0.19.0](https://github.com/vanniktech/gradle-maven-publish-plugin/blob/master/CHANGELOG.md#version-0190-2022-02-26)
- A NPE in SingleApostropheDetector for atypical resource definitions

Expected behavior
I expect the output of getChangelog to reflect the input markdown, including pre-formatted text with backticks `.

Environment:

• OS: macOS 13 & ubuntu 22
• Gradle Changelog Plugin Version 1.3.1 & 2.0.0
• Gradle Version 7.5.1

This ticket and the newer ticket #147 look like they probably have the same root cause.
