Skype Insider Preview now supports up to 100 participants within calls. The update doubles the previous limit of 50, making it easier to have large groups of people within a call. The update brings Skype to Insider build 8.66 and also includes some fixes.

With more people working from home and circles of friends and family having to communicate digitally, increasing the participant limit of calls is a welcome change. A limit of 100 people should be more than enough for many groups.
