Version 3.3 is a maintenance release that fixes many bugs, includes many improvements and changes, a new SCSSPHP library for building custom styles, and one important new feature made for testing purposes.
This version includes support for the URL query argument ‘quantum’. This argument can be used while the GD Quantum Theme Pro plugin is activated, but the Quantum theme is not enabled. Suppose you add the ‘?quantum’ to any forum URL. In that case, it will load Quantum for that page only, and you can compare the normal bbPress theme package with the Quantum-enabled forum without activating and deactivating Quantum every time. If the page is loaded with the ‘quantum’ argument, all URL’s on that page will be modified to apply the ‘quantum’ argument on click.
As for the changes, this version includes the latest SCSSPHP library used to build custom styling. It also has improved styling for the profile editing password field, many tweaks to the TinyMCE enabled editor, and all the CSS modifications are updated. Obsolete TFT and SVG font files are removed from the icons font. There are many changes to the JavaScript files loaded on the frontend, including structure and initialization process.
And it also fixes several bugs: problems with the password field in the profile editing, a few minor and rare issues related to the CSS building, and issues with the size and alignment of the topic header elements.
