Bug Fixes and New Features

Issues Resolved

• Fix for #246 progressbar CSS issues. Update the CSS overall and fix the 1px off issue.
• Add enable_pygments option in settings to allow Pygments to not be used. This is to solve frustrations that some users have who want to use a Javascript syntax highlighter. #248
• Update the default github.css to the latest version from https://github.com/sindresorhus/github-markdown-css. Also update the github Pygments style to the last Pygments update that Github had made before they abandoned using Pygments. Also add the old Pygments Github style as githubclassic. #252
• Add support for translating paths to relative paths (in relation to HTML output). #247

Other Fixes

• Fix CSS bug where code blocks in Python Markdown output had no spacing between them

New

• Remove obsolete b64 extension (as Markdown Preview uses a global base64 converter).
• Remove obsolete admonitionicon extension as this is now done with pure CSS.
• Upgraded some 3rd party extensions:
  • githubemoji: upgrade to latest (no functional changes)
  • headeranchor: Add itself without needing changes to toc extension
  • magiclink: Even better regex rules to fix some corner cases
  • tasklist: No functional changes
  • github: Now includes superfences by default
  • progressbar: Now requires title to be quoted (no longer optional). Inline settings support is removed in favor of using inline attr_list support (new). Syntax now requires only one equal sign, but can take any number now. addclasses and levelclass settings renamed to add_classes and level_class.
• toc extension reverted to its original form as it no longer conflicts with headeranchor
• Plain html option now also strips html comments. Also re-written to be better and more straight forward.
• base64 conversion now ignores content in html comments
• absolute and relative path conversions can now handle paths with trailing html fragments, like when it is desired to jump to a page and jump to a header on that page => path/to/myfile.html#some-header. The trailing fragment will now be preserved.
• Add superfences extension which allows for nesting of fenced code blocks in lists, admonitions, blockquotes, etc.
• Add UML flowchart and sequence diagram support through superfences. Requires flowchart.js and sequence-diagram.js which are provided (and their dependancies through CDNs; flowchart.js has no CDN so it is directly included).
• Update test file with new progressbar example and new flowchart and sequence diagram examples.
• Update readme in relation to changes and fix bad link.
• Better admonition styling that doesn't clash with other element's styling.
