It’s almost July 2019, so you’re probably not using Windows Phone 8.x devices anymore. If you are, you should know that Microsoft will no longer be delivering app updates to your devices. Developers of such apps can still continue to write and push out updates — they’ll just only reach Windows 10 mobiles.
Windows 8 and 8.x PCs have a longer leeway, with Microsoft continuing to deliver updates for four more years.
Developers should not be caught flat-footed by this development, Microsoft announced as much earlier last fall:
July 1st, 2019 – Microsoft will stop distributing app updates to Windows Phone 8.x or earlier devices – You’ll still be able to publish updates to all apps (including those with Windows Phone 8.x or earlier packages). However, these updates will only be made available to Windows 10 devices.
Windows 10 Mobile users may still be affected. WhatsApp for one notes that it may leave the Microsoft Store entirely after today. Facebook and Messenger already left, and other apps are dropping as well. This is probably not a big deal for most people but is something to be aware of if you want to continue using the platform for whatever reason.
