Changes

• Upgraded jQuery to 3.3.1 and jQuery.ui to 1.12.1
• Upgraded D3 Javascript framework to v5.9.2 (core/assets/js/d3.js)
• LaTeX math formula support changed to use MathJax. This will remove an approximately 3Gb dependency on the HUBzero install in future releases.
• Moved several duplicated language strings down to a single core language string.
• Projects /projects/browse page has been redesigned to use "cards" instead of a table.
• Projects now use the standard access column (Admin > Users > Access Levels) to control visibility, allowing projects to be assigned to specialized access levels and, thus, only viewable/findable by people who can view said access level.
• HUBzero copyright block (found at the top of all the code files) updated, simplified, and significantly reduced in size.

Removed

• Removed select2.js and associated CSS. Use jquery.fancyselect.js instead.
• Removed core/libraries/fpdf and core/libraries/fpdi libraries. Code using them was refactored to use TCPDF instead.
• Removed core/libraries/nusoap. Library was unused.
• Removed core/libraries/simplepie. SimplePie is included via Composer instead.
• Removed unused views/*/tmpl/{view name}.xml files. View XML files are used for providing params for menu items and aren't currently supported for plugin views.

New Features

• More filters for Activity API. You can now provide a start_date and end_date to retrieve activity in a specified time range.
• Group Forums: Added configuration option for default sorting of threads (last activity, created, number of replies, thread title).
• Previously only supported by components, all extension types now support a /config directory for configuration options.

  /modules
  .. /mod_foo
  .. .. /config
  .. .. .. config.xml
  

  This keeps the structure of extensions more consistent.
• Courses: Add ability to add tools + files to be used with the tool when invoking a session from a course.
