 ## [Unreleased]
+### Added
+* Enable IntelliJ-compatible token `$today.year` for specifying the year in license header files. ([#542](https://github.com/diffplug/spotless/pull/542))
 ### Build
 * All `CHANGES.md` are now in keepachangelog format. ([#507](https://github.com/diffplug/spotless/pull/507))
 * We now use [javadoc.io](https://javadoc.io/) instead of github pages. ([#508](https://github.com/diffplug/spotless/pull/508))
 * We no longer publish `-SNAPSHOT` for every build to `master`, since we have good [JitPack integration](https://github.com/diffplug/spotless/blob/master/CONTRIBUTING.md#gradle---any-commit-in-a-public-github-repo-this-one-or-any-fork). ([#508](https://github.com/diffplug/spotless/pull/508))
 * Improved how we use Spotless on itself. ([#509](https://github.com/diffplug/spotless/pull/509))
 * Fix build warnings when building on Gradle 6+, bump build gradle to 6.2.2, and fix javadoc links. ([#536](https://github.com/diffplug/spotless/pull/536))
-* Enable IntelliJ compatible tokens for specifying the year in license header files ([#542](https://github.com/diffplug/spotless/pull/542))
 
 ## [1.27.0] - 2020-01-01
 * Ignored `KtLintStepTest`, because [gradle/gradle#11752](https://github.com/gradle/gradle/issues/11752) is causing too many CI failures. ([#499](https://github.com/diffplug/spotless/pull/499))

 ### Fixed
 * Eclipse-WTP formatter (web tools platform, not java) could encounter errors in parallel multiproject builds [#492](https://github.com/diffplug/spotless/issues/492). Fixed for Eclipse-WTP formatter Eclipse version 4.13.0 (default version).
 
 ## [3.27.2] - 2020-03-05
+### Fixed
 * Add tests to `SpecificFilesTest` to fix [#529](https://github.com/diffplug/spotless/issues/529)
 * If you applied spotless to a subproject, but not to the root project, then on Gradle 6+ you would get the deprecation warning `Using method Project#afterEvaluate(Action) when the project is already evaluated has been deprecated.`  This has now been fixed.
