LSM9DS1 A 9 degree of freedom Inertial Navigation Chip

I pulled up the datasheet for the LSM9DS0 and did a quick glance and found there are differences. For instance:

LSM9DS0
Table 40. FIFO mode configuration
FM2 FM1 FM0 FIFO mode
0 0 0 Bypass mode
0 0 1 FIFO mode
0 1 0 Stream mode
0 1 1 Stream-to-FIFO mode
1 0 0 Bypass-to-Stream mode

LSM9DS1
Table 84. FIFO mode selection
FMODE2 FMODE1 FMODE0 Mode
0 0 0 Bypass mode. FIFO turned off
0 0 1 FIFO mode. Stops collecting data when FIFO is full.
0 1 0 Reserved
0 1 1 Continuous mode until trigger is deasserted, then FIFO
mode.
1 0 0 Bypass mode until trigger is deasserted, then Continuous
mode.
1 1 0 Continuous mode. If the FIFO is full, the new sample overwrites
the older sample.```
