=== raindrops 0.9.0 - minor middleware/proxy update / 2012-05-21 00:06 UTC

  Raindrops::Middleware::Proxy now forwards method_missing
  to the proxied body object.  This allows compatibility
  with non-standard Rack extensions employed by some
  middlewares, applications, or servers.

  Thanks to Ben Somers for the feature!

=== raindrops 0.8.1 - compatibility fixes / 2012-05-12 05:58 UTC

  This release fixes a build problem found under a current SmartOS.  This
  release also runs successfully on FreeBSD 9.0 under both x86-64 and
  i386.

  There are also documentation updates from Aman Gupta and a test suite
  fix from Jeremy Evans for OpenBSD.

  raindrops fully supports unicorn on recent versions of FreeBSD, OpenBSD,
  SmartOS, and possibly other Free Software systems.  Portability reports
  and fixes for Free Software systems is greatly appreciated at
  raindrops@librelist.org

  Non-Free systems will never be supported.

  raindrops requires the Linux 2.6.18 or later for full functionality
  (which unicorn does not require).  Future releases will take advantage
  of the unix_diag functionality found in the Linux 3.3 (and later)
  kernels.
