An NB9 app update is often described as a small file with a new number. The number is useful. The permission prompt that follows it is more useful. This page records what we look at when readers ask what changed.
What a version number is for
A public page may list a build such as 2.0.x and a size in megabytes. Treat those figures as a snapshot, not as a promise that the next file with the same name is genuine. Write the number down before you update so you can compare it later.
Permission prompts
If a later prompt asks for SMS, contacts, or accessibility access that gameplay does not need, stop. Updates can add modules. They should not quietly expand into your message list.
Release notes versus splash art
Marketing art changes more often than the wallet rules. Read the in-app terms after an update, especially any line about minimum withdrawal or document checks. For reward headlines, see How to read in-app rewards without rushing.
Where we keep notes
We publish update explainers under App Updates. We do not host the file. If you are reviewing a package source, use the NB9 APK page first.
