Features

  - Added a ``repoze.bfg.testing`` module to attempt to make it
    slightly easier to write unittest-based automated tests of BFG
    applications.  Information about this class is in the
    documentation.

  - The default template renderer now supports testing better by
    looking for ``ITestingTemplateRenderer`` using a relative
    pathname.  This is exposed indirectly through the API named
    ``registerTemplate`` in ``repoze.bfg.testing``.

  Deprecations

  - The names ``repoze.bfg.interfaces.ITemplate`` ,
    ``repoze.bfg.interfaces.ITemplateFactory`` and
    ``repoze.bfg.interfaces.INodeTemplate`` have been deprecated.
    These should now be imported as
    ``repoze.bfg.interfaces.ITemplateRenderer`` and
    ``repoze.bfg.interfaces.ITemplateRendererFactory``, and
    ``INodeTemplateRenderer`` respectively.

  - The name ``repoze.bfg.chameleon_zpt.ZPTTemplateFactory`` is
    deprecated.  Use ``repoze.bfg.chameleon_zpt.ZPTTemplateRenderer``.

  - The name ``repoze.bfg.chameleon_genshi.GenshiTemplateFactory`` is
    deprecated.  Use
    ``repoze.bfg.chameleon_genshi.GenshiTemplateRenderer``.

  - The name ``repoze.bfg.xslt.XSLTemplateFactory`` is deprecated.
    Use ``repoze.bfg.xslt.XSLTemplateRenderer``.
