Changes in version 1.1.2 (2011-07-07)
=====================================

Bugfixes
--------

  * :issue:`375`: The logic used to separate tasks from modules when running
    ``fab --list`` incorrectly considered task classes implementing the mapping
    interface to be modules, not individual tasks. This has been corrected.
    Thanks to Vladimir Mihailenco for the catch.
