When Skype made significant changes to its mobile app for Windows Phone 8 last month, I selected it as an app pick for the platform, noting that it was a big deal that fixed previous issues and added new features. This week, that app was updated again, this time to address a number of remaining issues. If you’re using Skype on Windows Phone 8, you’re going to want to upgrade.

Skype 2.5 for Windows Phone 8 is available now from the Windows Phone Store.

According to Skype, this update focuses on “general improvements and reliability.” It includes the following changes:

Messenger notifications on by default. Message notifications for Messenger buddies are now on by default.

Stability. Fixes an issues whereSkype crashed on startup for some users who signed in with Microsoft Account.

Notifications. Fixes an issues wheremessage notifications sometimes had contact names separated with 20% instead of a space.

Calling. Fixes an issues wherethevideo call button was disabled straight after accepting incoming contact request.

Video Calling. Fixes issues where the full screen local video preview was stretched sometimes and incoming 720p video on portrait mode was zoomed in.

There is still one known issue in this release: Users on HTC 8X who have not updated their phone to the latest firmware version will experience muted microphone on audio calls. The solution is obvious: Update your phone. :)
