Although Paranoid Android 7.2.3 is not considered to be a major update, this update delivers quite a few new languages, more customization options, as well as the usual bug fixes and minor tweaks that come with such releases.
The list of new languages consists of no less than 19 items, including popular languages and dialects like Chinese (both simplified and traditional), Arabic, UK English, Russian, Hindi, German, French, Polish, Spanish. The stock launcher gets icon customization and app labeling, so users can now apply icon packs and also change the icons and labels of each app as needed.
The official Paranoid Android 7.2.3 release notes mention some minor fixes and changes for quite a few handsets, including the Nextbit Robin, Nexus 5, OnePlus One, Xiaomi Mi5, or OnePlus 3/3T. Unfortunately, there is also a notice saying that "our Paranoid OTA may not update to this release version, so you might need to flash this build manually given the case." Fortunately, this build also comes with PA-OTA patches and the OTA update issues should go away in the future.
