Changes from the previous release:

- Buildout will no-longer install non-final releases if there are
  final releases that meet requirements.

  (IOW, the prefer-final buildout option now defaults to true.  You
   can get the old behavior by setting prefer-final to false.)

- You can now specify simple constrains in versions sections.

  Previously, you could only set versions, for example:

    zc.recipe.egg == 2.0.0a3

  But now you can specify that you want versions greater than or less
  then a given version:

    zc.recipe.egg == >=2.0.0a3

  This was added so that buildout2 can constrain the version of
  zc.recipe.egg used without requiring a specific version.

  buildout1 will be updated with this feature too, so that it can
  prevent itself from using newer versions of zc.recipe.egg and to
  prevent upgrading itself to buildout2.
