Show update warnings and information
Even though it was tried very hard to inform all users about Signal / Telegram app removal, still some users were quite suprised. So I think, it would be ideal if LineageOTA could offer extra information warning about major changes like Signal / Telegram App removal, that the Updater can present in a warning box, before users update to the affected versions.
This could also be used for updates changing the major Android version (e.g. Nougat->Oreo) show a warning that some settings may get lost.
