 We adhere to the [keepachangelog](https://keepachangelog.com/en/1.0.0/) format (starting after version `4.8.0`).
 
 ## [Unreleased]
+### Changed
+* Bumped minimum supported Eclipse JDT core version to 3.27.0
+* `format` interface requires source file information to distinguish module-info from compilation unit. Old interface marked as deprecated.
+### Fixed
+* Fixed module-info formatting. Previous versions did not recognized content and skipped formatting.
 
 ## [4.8.0] - 2018-07-19
 * Initial release!
