5.0.0 / 2015-10-05
------------------

- Internal API change. Due to new CM spec requirements, we had to update
  internals. That should not touch ordinary users, but can affect some external
  plugins. If you are plugin developper - see migration guide:
  https://github.com/markdown-it/markdown-it/blob/master/docs/5.0_migration.md.
- Updated CM spec compatibility to 0.22:
  - Keep tabs (don't replace with spaces).
  - Don't wrap iframes with paragraphs.
  - Rewritten emphasis algorithm.
- Fix closure compiler collisions (don't use reserved words), #159.


4.4.0 / 2015-07-18
------------------

- Updated HTML blocks logic to CM 0.21 spec.
- Minor fixes.

- Allow numbered lists starting from zero.
- Fix class name injection in fence renderer.


4.3.0 / 2015-06-29
------------------

4.2.0 / 2015-04-21
------------------

- Bumped [linkify-it](https://github.com/markdown-it/linkify-it) version to
  1.1.0. Now links with IP hosts and without protocols are not linkified by
  default, due possible collisions with some version numbers patterns (0.5.0.0).
  You still can return back old behaviour by `md.linkify.set({ fuzzyIP: true })`.


4.1.2 / 2015-04-19
------------------

  schema. Should not linkify things like `io.js` and `node.js`.

4.1.0 / 2015-03-31
------------------

- Security: disabled `data:` URLs by default (except some image mimes), to avoid
  possible XSS. Version bumped, because features changed (formally). If you did
  not used `data:` URLs, consider this version as 4.0.4 (no API changes).
- Simplified link validator code. Now more easy to understand and to copy
  into your projects for customization.
