Forum: Ruby kramdown 1.0.0 released -- MIT licensed!

## About kramdown

kramdown (sic, not Kramdown or KramDown, just kramdown) is a *free*
GPL-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 1.0.0 released

Finally! After four years of development I proudly present you

  kramdown **1.0.0**!

Naturally, it is recommened to update to this version.

Although the version number now starts with one, the changes from the
last release are mostly bug fixes and some small changes. The biggest
change is the **license change**: Until now kramdown was released under
the GPL but starting from 1.0.0 it is released under the **MIT
license**!

The MIT license allows the use of kramdown in a commercial setting.
However, if you are using kramdown in a commercial setting, I ask you
to contribute back any changes you make for the benefit of the
community and/or to make a donation - thanks in advance!


## Changes

* 4 minor changes

  - New option `transliterated_header_ids` for transliterating header
    text into ASCII before generating a header ID which is useful for
    language like Vietnamese (fixed [GH#35], requested by Kỳ Anh)

  - The quotation mark entity `"` now gets converted to its
    character equivalent when `entity_output=as_char`.

  - A warning is now output for IALs/ALDs that contain not attribute
    defintion.

  - HTML footnote output is changed to use `class` instead of `rel` to
    achieve (X)HTML4/5 compatibility

* 3 bug fixes

  - Fixed [GH#38]: Encoding problem on 1.9/2.0 due to incompatible
    encodings -- the source string is now converted to UTF-8 before
    parsing and converted back after converting (reported by Simon
    Lydell)

  - Fixed [RF#29647]: Abbreviations with non-word first character at
    start of text lead to exception (reported by Stephan Dale)

  - Fixed [RF#29704]: ID specified on atx style headers were not always
    correctly detected (reported by Kyle Barbour)

You should fix your announcement text then :-)

It not only allows use in commercial software -- it also allows use with
arbitrary other open source projects, where the various copyleft 
licenses
(notably including the GPL) are incompatible with other licenses.  Where
there is "compatibility", it is only one-way compatibility, allowing
other projects' sources to be used with the GPLed project, but not the
GPLed project's sources to be used in a differently-licensed open source
project.

I'll have to revisit my markdown library choices now that kramdown is
using a sane license, and see whether a migration from redcarpet to
kramdown is in order for the projects I maintain.
