A clarification, prompted by conversation with those who actually know about this: We can't "support" https: in the sense of making it work everywhere -- there are too many external entities involved, and libcurl support doesn't necessarily imply that https: works. What we have done in 3.2.2 is mainly to remove some stumbling blocks so that repositories can be accessed via https: *when that works* and ensure that there actually are HTTPS-speaking mirrors available.
