You can now embed youtube videos directly by using the new youtube button in the editor (upper right corner above the text field). Or you can type the [youtube] [/youtube] tag directly if you like.
There's also the new "spoiler" button that adds a black background to the text between the tags. Readers must mark the text with their mouse in order to read it. I suggest not to use it too often. It becomes annoying when a lot of posts are more blacked out than usual text.
Enjoy!
