### Security
- Fix quadratic parse time for some combinations of pairs, #583. Algorithm is

### Changed
- Minor internal structs change, to make pairs parse more effective (cost is
  linear now). If you use external "pairs" extensions, you need sync those with
  "official ones". Without update, old code will work, but can cause invalid
  result in rare case. This is the only reason of major version bump. With high probability you don't need to change your code, only update version dependency.

## [6.0.3] - 2016-05-30
### Security
- Security fix: possible ReDOS in `linkify-it` (forced bump of `linkify-it` &
  `uc-micro` dependencies). New installs will use fixed packages automatically,
  but we bumped `markdown-it` version for sure & for web builds.


## [6.0.2] - 2016-05-16

  plugins. If you are plugin developper - see migration guide:
  https://github.com/markdown-it/markdown-it/blob/master/docs/5.0_migration.md.
