New Features
General
- Add automatically updating live preview functionality (C-c C-c l)
via the native eww browser.
- Use autoload to enable markdown-mode in auto-mode-alist for files
with .text, .markdown, and .md extensions.
- Use Travis CI for automated build testing.
Element Insertion and Editing
- ATX heading subtree promotion and demotion via M-S-LEFT, and
M-S-RIGHT.
- ATX heading subtree moving up and down via M-S-UP and
M-S-DOWN.
- Convert inline links to reference links when
markdown-insert-reference-link-dwim is used when the point is at
an inline link.
Customizable Features
- Allow linking to multiple stylesheets in markdown-css-paths
list. Use stylesheets for both preview and export. Previous
markdown-css-path (singular) is now deprecated.
- Customizable default unordered list marker via

markdown-asymmetric-header.
Font Lock
- Separate highlighting for Markdown markup characters (asterisks,
underscores, backquotes, etc.) to aid in readability.

blockquotes, headings, horizontal rules, bold, italics
- Font lock for bold, italics, and LaTeX math work inside block
elements such as headings and blockquotes.
- Font lock for <kbd> tags.
GFM
- Support GFM-style code blocks in markdown-mode (as well as
gfm-mode).
- New function markdown-electric-backquote will prompt for a
language name for GFM code blocks. This can be disabled by
customizing the variable markdown-gfm-use-electric-backquote.
- Completion of programming language names for GFM code blocks. A
list of pre-defined languages is included, but this can be
augmented by setting markdown-gfm-additional-languages.
- Strikethrough support in gfm-mode.
- Support for GFM toggling checkboxes mouse-1 or RET. This is
controlled by a new custom variable,
markdown-make-gfm-checkboxes-buttons.
Other Extensions
- Font lock and filling for Pandoc "fancy list", which use # as
the list marker.
- Basic support for filling of definition lists.
- Support Ikiwiki-style search for wiki links that allows links
relative to parent directories. Enable this by setting
markdown-wiki-link-search-parent-directories.
Bug Fixes

- Fix font-lock for GFM code blocks without language keywords.
- Improved Setext header insertion to support wide characters.
- Fix expensive paragraph-separate regular expression.
- Make comment-auto-fill-only-comments a buffer-local variable,
