Multiple Issues Post 4.4 Update

Have a whole cluster of issues post the 4.4 updates. To get it out of the way though I have:

1. Cleared Browser (Firefox 42.0, Windows 7 64 SP1) cookies and cache.
2. Disabled all plugins.
3. Switched theme to 2015 (unable to get 2016)
4. Using no caching (server side plugins)

Facing three issues that I’ve discovered so far, there may likely be more.

1. Media Library displays as blank. No thumbnails. Add new files button goes to loader (WP). Select files button does nothing. Javascript is enabled.

2. Themes. Add theme button goes to empty “download” form. No form names are retrieved.

3. Admin interfaces select all buttons no longer function. (they don’t toggle all).

In addition, my commercial theme, Story by Pexto, no longer seems to be able to communicate with the Envato market. It simply spins its wheels, attempting to reach them.

I had no issues before the 4.4 update. Beta appears to have failed you folks this time around. I will most assuredly think twice in the future before hitting that update button.
