The Manage add effects window

I canot find in my new Audacity 2.1.0 the Manage Add remove effects window. I have read in the help that i should find it the Effect menú. Has it desapear ? I must download from…? How can I disable plugins or vst without it?
Thanks in advanced

“Manage” appeared in Audacity 2.1.1


The on-line instructions always follow the current Audacity release.

That’s 2.1.1.
