Tired of downloading 300 MB everyday to get your latest ROM nightly build?
CyanDelta lets you update your LineageOS ROM Paranoid Android ROM or OmniROM by downloading just a small delta file (about 10 MB) instead of a big full zip file each time. With CyanDelta you can finally update your ROM in just some minutes even with a slow and expensive 2G or 3G connection!
CyanDelta is the perfect replacement of CM Updater ROM Manager and BBQLog. When a ROM update is available it will notify you and show the changelog between the version you have installed and the new one. If you decide to update it will delta-download the new version and if you want it will automatically install the new zips via recovery.

Main features:
✓ Security: all downloaded data is digitally signed by us to prevent manomissions.
✓ Recovery zip install: it can automatically reboot to recovery install the ROM zip and other additional zips (kernel modem...) wipe dalvik cache and reboot (requires root).
✓ Changelog: if you have a NIGHTLY build when an update is available CyanDelta will show you the list of changes between the ROM version you have installed and the new one.
✓ Update notification: when a ROM update is available CyanDelta will notify you.
✓ High efficiency deltas: it uses the RFC3284 VCDIFF algorithm and some magic to produce really small deltas.
✓ Supports TWRP and CWM-based recovery but NOT the closed-source ClockworkMod (the name is similar to CWM-based but it’s a different thing!) since it's locked down by its author to only work with ROM Manager. If you have an unsupported recovery you can just manually install the zips generated by CyanDelta.
✓ Supports all official LineageOS ROMs and devices listed in https://download.lineageos.org
