Publishing Updates

After your app has been published in AppCenter, you can issue a new update at any time by creating a new release. This will begin the submission process again for your app.

Updating Screenshots

Screenshots are uploaded to the AppCenter screenshot server at publication time. The URL referenced in your AppData.xml file will be automatically replaced during publication and any changes you make to images hosted at the remote URL will not be reflected in AppCenter.

If you change the UI of your app in an update, you must update your screenshots

Release Descriptions

You must add accurate release descriptions to your appdata.xml file when publishing an update. For more information on formatting, see the AppStream documentation for the tag. The version in your release should match the latest version submitted to AppCenter.

Release descriptions should be accurate, concise, and written for a typical user of your app—focus on user-visible and user-understandable changes, and simplify or omit technical "under the hood" changes. For example, a good release description might be:

New features:

  • Support for WebP images

  • Option to maintain aspect ratio when cropping

Other improvements:

  • Main view now loads twice as fast

  • Updated French translations

  • Other code cleaning

…while a poor one would be:

  • Fix bug #1234; rewrote method to be async

  • Linted all the code, removed trailing whitespace

  • Refactored utils

  • Updated VAPIs

Previous release descriptions can remain in your AppData in perpetuity; AppCenter may use these to display cumulative descriptions between an older installed version and the latest version.
