+ __New__
+ A mechanism for defining content containers.
+ Two new filters for the Jinja renderer, `items` and `values`, that act as syntactic sugar for `iteritems()` and `itervalues()`.
+ A reStructuredText parser.
+ Two new `item` properties, `prev` and `next`, that store the previous and next items in the container.
+ Files outside of ignored directories will now be parsed if a parser is available.
+ Two config settings for controlling how posts are sorted: `posts_order` and `posts_sort`.
+ __Changed__
+ Global and local dictionaries no longer behave different from ordinary Python dictionaries when iterating over them.
+ The `archives` and `tags` globals are now properties of the `posts` global to maintain consistency between content containers.
+ The `post` local has been renamed `item` to maintain consistency between content containers.
+ The `<title>` variable in URL formats has been renamed to `<slug>`.
+ Frontmatter attributes that contain string values can now be used in URL formats.
+ The `markup` and `parser` config settings have been removed.
+ Which parser used is now determined by _(in order of precedence)_ the `parser` frontmatter attribute, the `parser` container config setting, and lastly the file extension.
+ In Markdown, the bracket fenced code block syntax is no longer supported.
+ The `layout` frontmatter attribute can now be set to `None` to skip rendering.
