Skype 8, first introduced last year, features a total design overhaul that has not been popular with some customers, which led some Skype users to be unhappy with Microsoft's announcement.
As of today, as pointed out by Windows blog Thurrott, Microsoft has changed its mind following user feedback. In a forum post, the Skype team says that support for Skype 7 will not end in September, with the end of life date extended to an unknown time.
UPDATE: Based on customer feedback, we are extending support for Skype 7 (Skype classic) for some time. Our customers can continue to use Skype classic until then.It is not clear how long "some time" will be, but customers who prefer the design of Skype 7 can continue using that version of Skype instead of upgrading to Skype 8.
The Skype team also said that it is listening to customer comments and plans to introduce features customers have requested into Skype 8. Classic Skype for Mac can be downloaded directly from Microsoft, as can Skype 8.
