Markdown Mode 2.0 Release Notes

Markdown Mode version 2.0 was released on March 24, 2013. This
is a major new stable release with many new features, including some
changes to keybindings for element insertion and outline navigation.
This new stable version can be downloaded from the
Markdown Mode homepage. Below is a description of significant or
user-visible enhancements or bug fixes. See the Git repository
for a complete history of changes.

New Features

Keybinding Changes

Physical styles: element insertion commands prefixed by C-c
 C-p have been removed in favor of their logical style
 counterparts prefixed by C-c C-s.
Shift is now the preferred way to distinguish keybindings for two
 similar elements:

Insert an inline link with C-c C-a l or a reference
 link with C-c C-a L. The latter keybinding is new
 and preferred over C-c C-a r, which is deprecated.
Insert an inline image with C-c C-a l or a reference
 image with C-c C-a L. The latter keybinding and
 insertion functionality is new.
The new automatic header insertion function (more below) is
 bound to C-c C-t h, with C-c C-t H being a
 variant that indicates a preference for Setext headings.
Insert an ATX level-one heading with C-c C-t 1 or a
 Setext level-one heading with C-c C-t ! (!
 is S–1). The latter keybinding is new and is
 preferred over C-c C-t t, which is deprecated.
Insert an ATX level-two heading with C-c C-t 2 or a
 Setext level-two heading with C-c C-t @ (@
 is S–2). The latter keybinding is new and is preferred
 over C-c C-t s, which is deprecated.

Footnotes:

Insert new footnote: C-c C-f n has been changed to
 C-c C-a f.
Jump to footnote text: C-c C-f g has been superceded
 by C-c C-j (markdown-jump).
Jump to footnote marker: C-c C-f b has been
 superceded by C-c C-j (markdown-jump).
Kill footnote: C-c C-f k has been superceded by
 C-c C-k (markdown-kill-thing-at-point).

Several other new keybdings have been introduced and are described
 in more detail below.

Smarter Markup Insertion

Fast heading insertion with a single command which automatically
 calculates the type (atx or setext) and level (which can now be
 cycled quickly, see below). Prefix with C-u to promote
 the heading by one level or C-u C-u to demote the
 heading by one level. Headings with a specific level or type
 can still be inserted quickly with specific keybindings.
ATX heading insertion will use current line as heading text if not
 blank and there is no active region.
Setext heading insertion will prompt for heading title when there is
 no active region.
When the point is at a heading, the heading insertion commands will
 replace the heading at point with a heading of the requested level
 and type.
When there is no active region, the bold, italic, code, link, and
 image insertion commands will operate on the word at point, if any,
 so that you don’t have to have an active selection for simple
 modifications.
Repeating the bold, italic, or code insertion commands when the
 point is at an element of the corresponding type will remove the
 markup.
Smart list item insertion with M-RET, with indentation
 and marker determined by the surrounding context. Prefix with
 C-u to decrease the indentation by one level or
 C-u C-u to increase the indentation one level.
Indentation of preformatted text and blockquotes will be adjusted
 automatically in contexts where more indentation is required, as in
 nested lists. (For example, in Markdown, a preformatted text block
 inside a first-level list item must have eight spaces of
 indentation.)
Improved reference link insertion with label completion.

Use word at point as link text, if possible, when there is no
 active region.
Tab completion of reference labels from the set of currently
 defined references.
Reference link insertion no longer prompts for
 a URL or title if the label is already defined.
If no URL is given, create an empty reference definition
 and move the point there.
Customizable reference link location via
 markdown-reference-location.

Basic reference-style image markup insertion.
Multiple horizontal rule styles, customizable as a list of strings,
 which can be cycled through.
New URL insertion command for inserting plain URLs delimited by
 angle brackets (C-c C-a u). Works on URL at point, if any,
 when there is no active region.
Generally improved insertion commands with respect to insertion of
 surrounding whitespace and point position after insertion
 (e.g., ensuring blank lines before and after newly inserted headings
 and horizontal rules).

Markup Removal

Easily kill an element (e.g., a link or reference definition) at the
 point and store the most important part in the kill ring (e.g., the
 link text or URL).

Markup Completion

Completion (C-c C-]) normalizes the markup for an
 element:

balancing hash marks and removing extra whitespace for atx
 headings,
equating the length of the underline with the text for setext
 headings, and
ensuring that horizintal rule strings are chosen from a
 pre-defined list of strings (markdown-hr-strings).

Markup Promotion and Demotion

Markup promotion and demotion via C-c C— and C-c
 C-=, respectively. The sequences M-<up> and
 M-<down> may also be used.
Certain types of markup may be promoted or demoted: atx headings,
 setext headings, horizontal rules, and list items.
 Bold and italic also be toggled between asterisks and
 underscores.
Promotion and demotion commands also cycle when level boundaries are
 reached (e.g. when demoting a level six heading, it cycles back a
 level one heading).

List and Region Editing

Move list items uper and more
 accurate. The pre block matching routines have been completely
 rewritten, with unit tests. The previous implementation was
 incorrect in some cases and generally slow. This should be much
 faster and more accurate for pre blocks inside nesterule for nested list items:
 in a list item of level n, preformatted text must be indented at
 least 4(n + 1) spaces.
Font lock for title strings in inline links.
Subtle syntax highlighting for hard line breaks.
More inclusive blockquote regular expressiofor more accurate syntax 
highlighting.

New and Improved Movement Commands

Jumping:

Quickly jump between reference definitions and reference-style links
 and between footnote markers and footnote text with
 C-c C-j.
Create undefined references when jumping from a reference link.
When jumping from a reference definition used by multiple
 reference links, show a temporary buffer with buttons for
 selecting which link to jump to. Possible locations may be
 cycled with TAB and S-TAB.

Revised outline navigation commands, following org-mode. This
 frees up the sexp navigation keys C-M-f and
 C-M-b which can be useful in Markdown documents which
 have many matching delimiters, as well as the defun navigation keys
 C-M-a and C-M-e.
Previous/next section movement with C-M-a and
 C-M-e (in Emacs parlance, this is movement by defun).
 Mark the current section with C-M-h.
Previous/next paragraph movement via M-{ and M-}.
Previous/next block movement with C-u M-{ and C-u M-}.

Link Following and Movement

Unified link following: open links in a browser and wiki links in a
 new buffer with the same keybinding (C-c C-o). This
 supercedes the separate wiki link following command
 (C-c C-w).
Generalized link movement and following: move between and open all
 link types (inline, reference, wiki, angle URIs) using the same key
 bindings (M-n and M-p). Previously, these
 commands only moved between wiki links, but with the above following
 enhancement, moving between hyperlinks of all types is more useful.
Remove wiki link following with RET and
 markdown-follow-wiki-link-on-enter setting.

Other Enhancements

Respect hard line breaks when filling paragraphs.
 A downside of this is that paragraph movement commands will also
 stop at hard line breaks, thus slightly changing the definition of
 “paragraph” in this mode. In those cases, use the new block
 movement commands instead.
Use adaptive filling for list items and blockquotes.

Treat all list items (any marker type) the same way with respect
 to filling.
Retain the > prefix when filling blockquotes.
Fill list items inside of blockquotes.

Add indentation positions: preceding list markers and pre block position.
imenu support.
Added before and after export hooks.

markdown-before-export-hook can make changes to the source
 buffer (e.g., preprocessing the Markdown source before running
 Markdown). Any changes made will be kept until the file is
 exported, so they will be incorporated into the resulting XHTML
 output, and the buffer will be restored to it’s original state
 after exporting.
markdown-after-export-hook may modify the resulting output
 buffer after export but before the output file is saved (e.g.,
 postprocessing the XHTML output).

Added a library of regression tests which currently contains 1cks for older 
Emacsen and Xemacs.
Numerous other internal improvements to make the code base more robust.
Use button-map for navigating undefined references, so that
 references can be navigated via the keyboard by pressing
 TAB and S-TAB.
Clean up whites:

Dynamic loading and unloading for math support with
 refontification.
Allow underscores and colons in equation labels.

GFM (GitHub Flavored Markdown) Mode Improvements

Changes italic font lock behavior to match GFM specification
 regarding underscores in words.
Syntax highlighting for GFM quoted code blocks with an optional
 language keyword.
Insertion command (C-c C-s P) for GFM quoted code blocks.

Bug Fixes

Fix bug in heading visibility cycling introduced in version 1.9
 where the level of headings was being calculated incorrectly.
Fix problems inserting ATX headings at end of buffer.
Support small Setext headings (with fewer than three characters).
Several improvements to inline code syntax highlighting.

No need to prohibit spaces after the leading backquotes.
Markdown allows more than two leading backquotes (but the same number
 must appear at the end to close the code tag).
Ensure following character is not a backquote.
Fix a bug where code fragments separated by a single character
 were not highlighted correctly. (This is difficult or impossible
 to do with regular expressions in Emacs, which do not support
 negative lookahead or negative lookbehind, so a matching function
 is used now.)

Fix some edge cases regarding escaping, spaces, etc. for bold and
 italic font lock.
Prohibit newlines and tabs immediately after opening bold and italic
 delimiters. This fixes a bug where italics would not be
 highlighted following a horizontal rule
Improved multi-line font lock performance for large files.
Improved multi-line font lock at beginning of buffer.
List items with any of the three markers are filled in the same way
 (previously list items starting with + were not filled with
 hanging indentation).
Fix end detection for empty list items. Don’t skip over the
 whitespace following the marker on the same line. Previously, empty
 list items were not being detected properly by
 markdown-cur-list-item-bounds as a result of this.
Don’t exclude [^], which is a valid reference tag (but let’s
 please stick to alphanumeric characters).
No longer highlight escaped wiki links.
Fix line number buttons for reference checking and make all buttons
 clickable.
Fix killing of footnotes with no text.
Fix escaping in markdown-xhtml-standalone-regexp.
Fix a font-lock edge case involving footnote markers preceding
 inline links.
More accurate font-lock for ATX headings in edge cases.
Fix killing of footnotes from footnote text.
