I recently learned that you can beta test Cygwin 1.7, the next big release of Cygwin. And the best part is that you can use the current version and the new version together:
Please keep in mind that this is a TEST release. Don't use in critical production environments. Nevertheless I'd like to encourage everyone to give 1.7 a try. Due to internal changes it is possible to install a 1.7 release in parallel to a 1.5 release and even run 1.7 processes in parallel to 1.5 processes. The processes will not know about each other!
For a Unix Geek like me living on Windows, this is really excellent news. It's not even the feature set of 1.7 that's so exciting - it's just that Cygwin is still a living, breathing project.
What are you waiting for, give it a try.
