Compose* v0.9.0 marks a new era in the history of Compose*. Starting from this release a new syntax for the concerns will be used. The syntax used in previous releases can still be used, but it will be phased out in the future. This new syntax (dubbed "canonical notation"), will affect the notation of the "filter elements". This new syntax provides more freedom in expression of the messages which should be accepted by the filter. More information about the new syntax is available here.

A small update to the previous 0.8.5 release. The previous Compose*/Java releases were not fully compatible with non-Windows systems. This was due to an incorrect format of the classpath given to the java compiler. The StarLight release is not affected by this issue, so only the Compose*/Java release has been updated. You only need to update if you are using Compose*/Java on a non-Windows operating system.

Compose* has been in development since 2003. In the past years a lot of research has been performed on various aspects of composition filters and the Compose* tool. The result of this research required various changes to the various parts of a core part of the Compose* too: the CPS language repository (which contains an AST of the Compose* language, and various other information produced by the tool). These changes were not always possible in the most gracious way. The language repository could be improved in a lot of ways.
