1.5.5 (Pending)
+* Fixed: The concatenation extension released as part of 1.5.4 changed the way zip archives were
+ constructed so that entries for some intermediate directories were elided. For most consumers
+ of zip files this had no impact but some tools require the entries during scanning. (i.e. Older
+ versions of Jruby that loaded ruby scripts from within a jar).
* Added: IDEA Extension: Added support for passing `:iml_name` parameter to `ipr.add_gwt_configuration`
1.5.4 (2017-11-29)
