## About kramdown

kramdown (sic, not Kramdown or KramDown, just kramdown) is a *free*
MIT-licensed [Ruby](http://www.ruby-lang.org) library for parsing a
superset of Markdown. It is completely written in Ruby, supports
standard Markdown (with some minor modifications) and various
extensions that have been made popular by the PHP Markdown Extra
package and Maruku.

## kramdown 1.4.0 released

This release fixes all outstanding bugs, so it is recommended to
update. The one new feature is that the location of the footnotes can
now be defined by attaching the reference name "footnotes" to an
ordered or unordered list (like with the table of contents).

One major problem was that unescaped pipe characters `|` often led to
involunatary tables. This release introduces some changes that should
prevent this for more cases than before. Additionally, since this is
the most common problem case, it is advised to use `\vert` instead of
`|` in inline math statements. Both do the same in LaTeX but the latter
may inadvertently start a table, so better use the former!


## Changes

* 2 minor changes:

- Implemented [#106]: Users can now define the location of the
footnotes (feature request by Matt Neuburg)
- Merged [#97]: `rake gemspec` now generates a local
`kramdown.gemspec` file (pull request by Nathanael Jones)

* 9 bug fixes:

- Fixed [#128]: `<script>` tags are now removed from math statements
when converting to HTML (reported by Trevor Wennblom)
- Fixed [#129]: Internal state of custom string scanner class was
corrupted due to backtracking which led to problems with location
tracking (reported by Mark Harrison)
- Fixed [#112]: The content of `<kbd>`, `<samp>` and `<var>` is now
also treated as raw HTML (reported by Denis Defreyne)
- Fixed [#114]: Added missing HTML entity names (reported by Tomer
Cohen)
- Fixed [#101]: Fixed exception on missing alignment information when
parsing HTML tables to native kramdown elements (initial pull
request by zonecheung)
- Fixed [#117]: The GFM parser now needs a space after a hash so that
the line is identified as an atx header (reported by Trevo Wennblom)
- Fixed [#131]: Location tracking in nested list was incorrect
(reported by Mark Harrison)
- Fixed/Worked around [#23], [#46], [#107], [#134]: Parsing math
blocks that contain pipe characters now works, adjusting inline math
statements to use `\vert` instead of `|` resolves the other problems
(reported by many)
- Fixed [#135]: Escaped pipes in alternative text of image links were
not correctly escaped (reported by Philipp Rudloff)
