- Add support for the new USRP B310, a PCIe/Thunderbolt-based device which
supports 2x2 RF channels at up to 100 MHz bandwidth per channel.
- Add support for X410, X420 and X440 variants with locked FPGA
- Update underlying OE version on embedded devices to Scarthgap (5.0 LTS).
Note that some of the MPM updates require this update.
- Update underlying OE version on embedded devices to Scarthgap (5.0 LTS)
and Linux kernel to version 6.12.
- Migrated the MPM RPC transport layer from mprpc (msgpack-RPC) to gRPC/Protobuf,
impacting all embedded devices running MPM.

- X420 and X440:
- The X420_X4_200, X420_CG_400, X420_X4_400 and X440_X4_200 FPGA images now use
fixed fabric resamplers (3x) and RFDC resamplers instead of RFDC resamplers alone.
This ensures repeatable phase offsets between devices and reboots. Note that
this feature is currently mutually exclusive with dual rate support, and it
- The X420_X4_200, X420_CG_400, X420_X4_400 and X440_X4_200 FPGA images now
use fixed fabric resamplers (3x) and RFDC resamplers instead of RFDC
resamplers alone. This ensures repeatable phase and time offsets between
repeatability events on these updated FPGA images. Note that this feature
is currently mutually exclusive with dual rate support on X440, and it
increases the resource utilization. To revert to the previous image with
non-repeatable phase offsets, a custom image must be built.
