   * This change allows the maven plugin to cache classloaders across subprojects when loading config resources from the classpath (fixes [#559](https://github.com/diffplug/spotless/issues/559)).
   * This change also allows the gradle plugin to work with the remote buildcache (fixes [#280](https://github.com/diffplug/spotless/issues/280)).
 * **BREAKING** Heavy refactor of the `LicenseHeaderStep` public API.  Doesn't change internal behavior, but makes implementation of the gradle and maven plugins much easier. ([#628](https://github.com/diffplug/spotless/pull/628))

+* **BREAKING** Removed all deprecated methods and classes from `lib` and `lib-extra`.
   * [#629](https://github.com/diffplug/spotless/pull/629) removes the code which wasn't being used in plugin-gradle or plugin-maven.
+  * [#630](https://github.com/diffplug/spotless/pull/630) moves the code which was still being used in deprecated parts of plugin-gradle into `.deprecated` package in `plugin-gradle`, which allows us to break `lib` without a breaking change in `plugin-gradle`.

 ### Added
 * Full support for the Gradle buildcache - previously only supported local, now supports remote too. Fixes [#566](https://github.com/diffplug/spotless/issues/566) and [#280](https://github.com/diffplug/spotless/issues/280), via changes in [#621](https://github.com/diffplug/spotless/pull/621) and [#571](https://github.com/diffplug/spotless/pull/571).
 * `prettier` will now autodetect the parser (and formatter) to use based on the filename, unless you override this using `config()` or `configFile()` with the option `parser` or `filepath`. ([#620](https://github.com/diffplug/spotless/pull/620))
+* (user-invisible) moved the deprecated lib code which was only being used in deprecated parts of `plugin-gradle` into the `.libdeprecated` package. ([#630](https://github.com/diffplug/spotless/pull/630))
 ### Fixed
 * LineEndings.GIT_ATTRIBUTES is now a bit more efficient, and paves the way for remote build cache support in Gradle. ([#621](https://github.com/diffplug/spotless/pull/621))

+### Removed
+* **BREAKING** the long-deprecated `<xml>` and `<css>` formats have been removed, in favor of the long-available [`<eclipseWtp>`](https://github.com/diffplug/spotless/tree/main/plugin-maven#eclipse-wtp) step which is available in every generic format.
+  * This probably doesn't affect you, but if it does, you just need to change `<xml>...` into `<formats><format><eclipseWtp><type>XML</type>...`
+  * In [`1.15.0` (released 2018-09-23)](#1150---2018-09-23), we added support for `xml` and `css` formats using the Eclipse WTP.
+  * In [`1.18.0` (released 2019-02-11)](#1180---2019-02-11), we deprecated these, in favor of the generic `eclipseWtp` step which is available for all generic formats.  This allows you to have multiple XML and CSS formats, rather than just one.
+  * And now we removed them entirely.
