1.5.0

Bug Fixes

• lists: enforce 4 space indentation in sublists (d51be6e)
• lists: fix sublists inconsistent behavior (9cfe8b1), closes #299

Features

• disableForced4SpacesIndentedSublists: option that disables the requirement of indenting nested sublists by 4 spaces. The option is disabled by default (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:

* one
  * two
    * three

Before (ouput):

<ul>
  <li>one
    <ul>
      <li>two
        <ul><li>three</li></ul>
      <li>
    </ul>
  </li>
<ul>

After (output):

<ul>
  <li>one</li>
  <li>two
    <ul><li>three</li></ul>
  </li>
</ul>

To migrate either fix source md files or activate the option disableForced4SpacesIndentedSublists:

showdown.setOption('disableForced4SpacesIndentedSublists', true);
