After a huge problem with notifications recently, WhatsApp has pushed out a significant update to their Windows Phone app which takes it to version 2.10.488.

The most significant of these is (on windows phone 8) that WhatsApp no longer uses background audio to maintain a connection to their service, but instead uses a proper background agent. This will solve a large number of bugs users have been experiencing with unreliable connections.

The app also has an improved UI, supports Fast Resume, the Notification bugs has been fixed and it supports new languages.

See the full changelog after the break.
