Today Mac users can download the official release of Skype 2.5. A beta of this has been out since late last year, but now Skype is happy to release a full stable version out into the wild.
It’s also important to note that if you were considering buying Skype Out to make calls anywhere in the US or Canada for free for the year at the discounted price of $14.95 (a heck of a deal, in my opinion) today is the last day to do it! After today the price will increase to $30 (which is still less than I pay for 1 month of phone service).
