# [1.5.0](https://github.com/showdownjs/showdown/compare/1.4.4...1.5.0) (2016-11-11)
### Bug Fixes
* **lists:** enforce 4 space indentation in sublists ([d51be6e](https://github.com/showdownjs/showdown/commit/d51be6e))
* **lists:** fix sublists inconsistent behavior ([9cfe8b1](https://github.com/showdownjs/showdown/commit/9cfe8b1)), closes [#299](https://github.com/showdownjs/showdown/issues/299)
### Features
* **disableForced4SpacesIndentedSublists:** option that disables the requirement of indenting nested sublists by 4 spaces. The option is disabled by default ([0be39bc](https://github.com/showdownjs/showdown/commit/0be39bc))
### BREAKING CHANGES
* syntax for sublists is now more restrictive. Before, sublists SHOULD be
indented by 4 spaces, but indenting at least 2 spaces would work.
Now, sublists MUST be indented 4 spaces or they won't work.
With this input:
```md
* one
* two
* three
```
Before (ouput):
```html
- one
```
After (output):
```html
```
To migrate either fix source md files or activate the option `disableForced4SpacesIndentedSublists`:
```md
showdown.setOption('disableForced4SpacesIndentedSublists', true);
```

### Release Information
This is a major code refactor with some big changes such as:
- showdown.js file was split in several files, called sub-parsers. This should improve code maintainability.
- angular integration was removed from core and move to its own repository, similar to what was done with extensions
- A new extension registering system is on the "cooks" that should reduce errors when using extensions. The old mechanism
is kept so old extensions should be compatible.
### Bug Fixes
* **extensions:** support for old extension loading mechanism ([95ed7c68](http://github.com/showdownjs/showdown/commit/95ed7c68))
* **helpers:** fix wrong function call 'escapeCharacters' due to old strayed code ([18ba4e75](http://github.com/showdownjs/showdown/commit/18ba4e75))
* **showdown.js:**
- fix showdown extension loader ([a38c76d2](http://github.com/showdownjs/showdown/commit/a38c76d2)),

### Features
* **registerExtension():** new extension loading mechanism. Now extensions can be registered using this function.
The system, however, is not final and will probably be changed until the final version([0fd10cb] (http://github.com/showdownjs/showdown/commit/0fd10cb))
* **allowBlockIndents:** indented inline block elements can now be parsed as markdown ([f6326b84](http://github.com/showdownjs/showdown/commit/f6326b84))

### Breaking Changes
* **NAMESPACE:** showdown's namespace changed.
To migrate your code you should update all references to `Showdown` with `showdown`.
* **Converter:** converter reference changed from `converter` to `Converter`.
To migrate you should update all references to `Showdown.converter` with `showdown.Converter`
* **angular:** angular integration was removed from core and now lives in it's own [repository](http://github.com/showdownjs/angular/).
If you're using angular integration, you should install ng-showdown. Ex: `bower install ng-showdown`
