- add gpg sig

  against a module compiled to the filesystem would
  fail trying to produce a RichTraceback due to the
  content being in bytes. [ticket:209]

  from tuple to frozenset, as this is expected to be
  a set by default.  [ticket:208]

  TemplateLookup, allows alternate Lexer classes
  to be used.

  Markupsafe isn't installed, was using an inline-compiled
  regexp which causes major slowdowns on Python 3.3;
  is now precompiled.

  raise exception when non-existent plugin
  is specified.

  <%text> tag so that it pulls locally specified
  identifiers from the context the same
  way as that of <%block> and <%filter>.

  function arguments inside pure-python def
  or lambda expressions.  [ticket:201]

  parsing for Py2.4 was broken.
  [ticket:193]

  involving variables declared in defs and such,
  which only became apparent when
  the strict_undefined flag was turned on.

  version checks and not allowing Mako 0.6 to
  recompile the module files.

  (even though several of those old template libs aren't
  available on Py3K, so YMMV) [ticket:175]

  in templates.   Usage of regions should be considered
  as superseding the very obsolete idea of passing in
  backend options, timeouts, etc. within templates.
- rewrite the cache docs again which had a lot of misleading/inaccurate
info.

  TemplateLookup, allows a callable to be passed which
  takes over the writing of the template's module source

  is now escaped with the HTML filter. [ticket:142]

  within extra arguments to <%block>, <%def>, i.e.

  Filters can also be used in this way, i.e.
  <%def name="foo()" filter="myfilter">
  then template.render(myfilter=some_callable)

  script, allows passing of kw to the template from
  the command line. [ticket:178]
