Delta update

[1] Fedora Linux has supported binary delta updates by default using the yum presto plugin since June 2009.

[2] This functionality has been inherited by Fedora-derived operating systems, including RedHat Enterprise Linux and its variant, CentOS.

A member of the developer team has proposed yet another format that integrates directly into the currently mirrored main repositories called patch debs in 2018.

[8] The Arch Linux package manager pacman used to support a form of delta updating using VCDIFF (xdelta).

[citation needed] Google's open source project Chromium requires frequent updates to narrow the window of vulnerability.

[15] Over-the-air (OTA) software updates have been used widely across many mobile devices; Apple iOS, Google Android, Microsoft Windows Phone 8, and BlackBerry 10.
