That doesn't appear to be the case.

"The woman who accused Julian Assange of rape has said she is 'shocked' by Sweden’s decision to drop the seven-year investigation."

This is curious, because I definitely remember someone recanting their allegations. It was a big deal. It's hard to find clear information on it now. Was there a second accuser maybe?

Edit: based on some other comments there may have been two accusers. In that case my original comment was misleading, thanks for the correction.
