About this APK

Mattermost is an app by Mattermost in the Business category, listed since at least March 2021. It includes native code only for x86 64-bit, so it won't install on ordinary ARM phones (only on x86 devices such as emulators and some Chromebooks).

Since version 2.37.2, the APK grew from 74 MB to 100.6 MB. It asks for 21 permissions, 5 of them sensitive, including precise location, camera and record audio. Compared with version 2.43.1, it adds 1 new permission: “Precise location”.

What's new in v2.44.0

Requires Android 7.0 or higher. - Added support for reporting client session attributes to the server. - Classification markings now load via a single property fields request on servers running v11.10+ (with backward-compatible fallback). - Improved Android cold start by decrypting credentials only for known servers instead of listing the entire Keystore. - Added various bug fixes.
