[0.6.0] - 2021-11-12

The TOC generator was rewritten, because the old on-the-fly generator couldn't deal with unexpected order of headings and double-indentations. It is now a three-step process:

1. Gather all headings in a list.
2. Turn that list into a nested tree.
3. Generate HTML code based on the nested tree.

Although all tests pass, this release could introduce some breaking changes for you, if you relied on the old way of doing things. Check the test cases to get a better understanding how this plugin handles various cases.

• Added: Support for markdown-it-attrs (fixes #54)
• Changed: Respects unexpected nesting order (fixes #55)
• Changed: Uses anchor targets from existing id attributes (for example, set by markdown-it-attrs or markdown-it-anchor)
• Changed: Now nests list correctly if there is a jump (for example: h2, h2, h4 -> h4 is now double-indented)
• Removed: unused tests
