Is there any changes di WYSIWYG editor?

Yesterday, there are a button on top-right of WYSIWIG editor that used to show BB code. Default, editor will using "simple mode" where we don't need to see BB code if we applied code to some words. And we can toggle between simple and advanced mode using that button.

Example:

Yesterday if we change color of a word, that word will appear in that color (i.e. red) directly. Now if we do that, we will see that color surrounded by BB color tag.

Click to expand...

Moreover, yesterday if we press enter to make a new paragraph actually editor will makes twice break line. Now it doesn't. I must to press enter twice manually to make more sense on my paragraph.

Why BHW disable that feature?
