mmark-ext-0.2.0.0: CHANGELOG.md

## MMark Ext 0.2.0.0

* The `skylighting` extension no longer accepts any arguments. Skylighting
  built-in facilities for rendering to HTML are not acceptable as they
  produce invalid HTML (with duplicate ids), so they were re-implemented.

## MMark Ext 0.1.1.0

* Added the `Text.MMark.Extension.MathJax` module.

* Added the `Text.MMark.Extension.Footnotes` module.

## MMark Ext 0.1.0.0

* This version has little in common with previous versions.

## MMark Ext 0.0.1.2

* Compiles with `modern-uri-0.2.0.0` and later.

## MMark Ext 0.0.1.1

* Fixed test suite failure with newer MMark versions. This version is to be
  used with `mmark-0.0.2.0` and later.

## MMark Ext 0.0.1.0

* Initial release.
