Microsoft has pushed out new updates for Lumia Camera Classic apps for Windows Phone Lumia users today, but there's no changelog for the app. This likely means just bug fixes.
The new version number of the app is 22.214.171.124.
Keep in mind that the Lumia Camera Classic app is made for Lumia devices that don't have the Demim firmware update. This app is also different from the Lumia Camera 5.0 app that's made just for the Lumia 830, Lumia 930, Lumia Icon and Lumia 1520 running on Denim.
If you notice any changes or improvements, let us know in the comments.
Update: An earlier version of this story erroneously reported that Lumia Camera was also updated. However, only Lumia Camera Classic received an update. We apologize for the confusion.
Thanks to everyone for the tips!
