Several 2.1 questions

1. The first is not a 2.1 question strictly speaking:

wordpress.org/download only makes the latest release
available.

What if I want to stick with 2.0.7 for a while before
going with 2.1?

Is 2.0.7 still available for download somewhere?

2. In 2.1, I hear there is a spell checker in the WYSIWYG
(Rich Text) editor. But for the life of me I cannot figure out
where under the Admin pages one can enable the WYSIWYG
editor.

I’ve read there should be an option under: Options -> Writing
to enable the WYSIWYG, but it’s simply not there.

Am I looking in the wrong place? How does one enable the
WYSIWYG under 2.1?

Thanks in advance.
