• [feature] Control lines with no bodies will
  now succeed, as "pass" is added for these
  when no statements are otherwise present.

• [bug] Fixed some long-broken scoping behavior
  involving variables declared in defs and such,
  which only became apparent when
  the strict_undefined flag was turned on.

  References: #192

• [bug] Can now use strict_undefined at the
  same time args passed to def() are used
  by other elements of the <%def> tag.

0.7.0

0.7.0

Released: Fri Mar 30 2012

• [feature] Added new "loop" variable to templates,
  is provided within a % for block to provide
  info about the loop such as index, first/last,
  odd/even, etc. A migration path is also provided
  for legacy templates via the "enable_loop" argument
  available on Template, TemplateLookup, and <%page>.
  Thanks to Ben Trofatter for all
  the work on this

  References: #125

• [feature] Added a real check for "reserved"
  names, that is names which are never pulled
  from the context and cannot be passed to
  the template.render() method. Current names
  are "context", "loop", "UNDEFINED".

• [feature] The html_error_template() will now
  apply Pygments highlighting to the source
  code displayed in the traceback, if Pygments
  if available. Courtesy Ben Trofatter

• [feature] Added support for context managers,
  i.e. "% with x as e:/ % endwith" support.

• [feature] Added class-level flag to CacheImpl
  "pass_context"; when True, the keyword argument
  'context' will be passed to get_or_create()
  containing the Mako Context object.

• [bug] Fixed some Py3K resource warnings due
  to filehandles being implicitly closed.

• [bug] Fixed endless recursion bug when
  nesting multiple def-calls with content.
  Thanks to Jeff Dairiki.

0.6.1

0.6.1

Released: Sat Jan 28 2012

• [bug] Added special compatibility for the 0.5.0
  Cache() constructor, which was preventing file
  version checks and not allowing Mako 0.6 to
  recompile the module files.

0.6.0

0.6.0

Released: Sat Jan 21 2012

• [feature] Template caching has been converted into a plugin
  system, whereby the usage of Beaker is just the
  default plugin. Template and TemplateLookup
  now accept a string "cache_impl" parameter which
  refers to the name of a cache plugin, defaulting
  to the name 'beaker'. New plugins can be
  registered as pkg_resources entrypoints under
  the group "mako.cache", or registered directly
  using mako.cache.register_plugin(). The
  core plugin is the mako.cache.CacheImpl
  class.

• [feature] Added support for Beaker cache regions
  in templates. Usage of regions should be considered
  as superseding the very obsolete idea of passing in
  backend options, timeouts, etc. within templates.

• [feature] The 'put' method on Cache is now
  'set'. 'put' is there for backwards compatibility.

• [feature] The <%def>, <%block> and <%page> tags now accept
  any argument named "cache_*", and the key
  minus the "cache_" prefix will be passed as keyword
  arguments to the CacheImpl methods.

• [feature] Template and TemplateLookup now accept an argument
  cache_args, which refers to a dictionary containing
  cache parameters. The cache_dir, cache_url, cache_type,
  cache_timeout arguments are deprecated (will probably
  never be removed, however) and can be passed
  now as cache_args={'url':, 'type':'memcached',
  'timeout':50, 'dir':'/path/to/some/directory'}

• [feature/bug] Can now refer to context variables
  within extra arguments to <%block>, <%def>, i.e.
  <%block name="foo" cache_key="${somekey}">.
  Filters can also be used in this way, i.e.
  <%def name="foo()" filter="myfilter">
  then template.render(myfilter=some_callable)

  References: #180

• [feature] Added "--var name=value" option to the mako-render
  script, allows passing of kw to the template from
  the command line.

  References: #178

• [feature] Added module_writer argument to Template,
  TemplateLookup, allows a callable to be passed which
  takes over the writing of the template's module source
  file, so that special environment-specific steps
  can be taken.

  References: #181

• [bug] The exception message in the html_error_template
  is now escaped with the HTML filter.

  References: #142

• [bug] Added "white-space:pre" style to html_error_template()
  for code blocks so that indentation is preserved

  References: #173

• [bug] The "benchmark" example is now Python 3 compatible
  (even though several of those old template libs aren't
  available on Py3K, so YMMV)

0.5.0

0.5.0

Released: Wed Sep 28 2011

• A Template is explicitly disallowed
  from having a url that normalizes to relative outside
  of the root. That is, if the Lookup is based
  at /home/mytemplates, an include that would place
  the ultimate template at
  /home/mytemplates/../some_other_directory,
  i.e. outside of /home/mytemplates,
  is disallowed. This usage was never intended
  despite the lack of an explicit check.
  The main issue this causes
  is that module files can be written outside
  of the module root (or raise an error, if file perms aren't
  set up), and can also lead to the same template being
  cached in the lookup under multiple, relative roots.
  TemplateLookup instead has always supported multiple
  file roots for this purpose.

0.4.2

0.4.2

Released: Fri Aug 5 2011

• Fixed bug regarding <%call>/def calls w/ content
  whereby the identity of the "caller" callable
  inside the <%def> would be corrupted by the
  presence of another <%call> in the same block.

  References: #170

• Fixed the babel plugin to accommodate <%block>

  References: #169

0.4.1

0.4.1

Released: Wed Apr 6 2011

• New tag: <%block>. A variant on <%def> that
  evaluates its contents in-place.
  Can be named or anonymous,
  the named version is intended for inheritance
  layouts where any given section can be
  surrounded by the <%block> tag in order for
  it to become overrideable by inheriting
  templates, without the need to specify a
  top-level <%def> plus explicit call.
  Modified scoping and argument rules as well as a
  more strictly enforced usage scheme make it ideal
  for this purpose without at all replacing most
  other things that defs are still good for.
  Lots of new docs.

  References: #164

• a slight adjustment to the "highlight" logic
  for generating template bound stacktraces.
  Will stick to known template source lines
  without any extra guessing.

0.4.0

0.4.0

Released: Sun Mar 6 2011

• A 20% speedup for a basic two-page
  inheritance setup rendering
  a table of escaped data
  (see http://techspot.zzzeek.org/2010/11/19/quick-mako-vs.-jinja-speed-test/).
  A few configurational changes which
  affect those in the I-don't-do-unicode
  camp should be noted below.

• The FastEncodingBuffer is now used
  by default instead of cStringIO or StringIO,
  regardless of whether output_encoding
  is set to None or not. FEB is faster than
  both. Only StringIO allows bytestrings
  of unknown encoding to pass right
  through, however - while it is of course
  not recommended to send bytestrings of unknown
  encoding to the output stream, this
  mode of usage can be re-enabled by
  setting the flag bytestring_passthrough
  to True.

• disable_unicode mode requires that
  output_encoding be set to None - it also
  forces the bytestring_passthrough flag
  to True.

• the <%namespace> tag raises an error
  if the 'template' and 'module' attributes
  are specified at the same time in
  one tag. A different class is used
  for each case which allows a reduction in
  runtime conditional logic and function
  call overhead.

  References: #156

• the keys() in the Context, as well as
  it's internal _data dictionary, now
  include just what was specified to
  render() as well as Mako builtins
  'caller', 'capture'. The contents
  of builtin are no longer copied.
  Thanks to Daniel Lopez for pointing
  this out.

0.3.6

0.3.6

Released: Sat Nov 13 2010

• Documentation is on Sphinx.

  References: #126

• Beaker is now part of "extras" in
  setup.py instead of "install_requires".
  This to produce a lighter weight install
  for those who don't use the caching
  as well as to conform to Pyramid
  deployment practices.

  References: #154

• The Beaker import (or attempt thereof)
  is delayed until actually needed;
  this to remove the performance penalty
  from startup, particularly for
  "single execution" environments
  such as shell scripts.

  References: #153

• Patch to lexer to not generate an empty
  '' write in the case of backslash-ended
  lines.

  References: #155

• Fixed missing **extra collection in
  setup.py which prevented setup.py
  from running 2to3 on install.

  References: #148

• New flag on Template, TemplateLookup -
  strict_undefined=True, will cause
  variables not found in the context to
  raise a NameError immediately, instead of
  defaulting to the UNDEFINED value.

• The range of Python identifiers that
  are considered "undefined", meaning they
  are pulled from the context, has been
  trimmed back to not include variables
  declared inside of expressions (i.e. from
  list comprehensions), as well as
  in the argument list of lambdas. This
  to better support the strict_undefined
  feature. The change should be
  fully backwards-compatible but involved
  a little bit of tinkering in the AST code,
  which hadn't really been touched for
  a couple of years, just FYI.
