Update: Over the course of the evening, ROM Manager was updated yet again, to version 220.127.116.11 - this time adding support for the TWRP recovery, which is undoubtedly a feature many users have been wanting for some time. Just update ROM Manager in the Play Store and you'll have it.
ROM Manager, one of the most useful and versatile tools available for a consummate ROM-flasher, got an update today, bringing the app up to version 18.104.22.168. The update brings just two changes – a bug fix, and something much more significant: support for delta downloads.
For those who are unfamiliar with the term, "delta downloads" are like the Play Store's smart updates, CyanogenMod's built-in update system, or the files users can download with CyanDelta – bite-size update files that only pack the things that have changed since your ROM's last build.
