Default [CM11] diff bootable/recovery and bootable/recovery-cm

Hey,

What is the difference between those two repos?
https://github.com/CyanogenMod/andro...le_recovery-cm
https://github.com/CyanogenMod/andro...table_recovery
Why did CyanogenMod make two dirs?

Moreover they pushed some commtis which give me awfull compile errors in minui/graphics_overlay.c

why are they pulling the rug out from under maintainers of older devices? This is annoying
I don't reply PM if the answer is on the forum.
