Errors when compiling LimeSuiteNG with gnuradio

One last question now that I’ve had some time to run some tests:

Has gr-limesdr been updated to use the new LimeSuiteNG API? There isn’t a reference to the XTRX and the sample rate is locked to 61.44e6. I tried removing the limit via the yml file but the next error I got was:

device_handler :info: SISO CH0 set for device number 0.
Lime Suite NG :info: Sampling rate set(100.000 MHz): CGEN:800.000 MHz, Decim: 2^1, Interp: 2^1
Lime Suite NG :error: lms7002m_set_frequency_cgen: requested frequency(800000000) too high
device_handler :warning: 

Separately, in this thread: Sample rate in LimeSuiteNG for Lime XTRX - #3 by ricardas

It’s mentioned that you need to use I12 format to reach a higher sample rate. Does that just mean that the data is packed and the upper 4 bits are truncated?
