# Arc 3.1.0

### DSM 7.3 Note :warning: 
Read before update to DSM 7.3:
- DSM 7.3 support is still in Beta stage
- DSM 7.3 will not work with some NIC for now (No eeprom read possible) <- can fail sometimes
- DSM 7.3 will not be able to use iGPU for now (No eeprom read possible) <- can fail sometimes
- DSM 7.3 should work for all Linux 4.4.x based DSM Platforms
- DSM 7.3 should work with SA6400 and enabled custom kernel for DSM (all official 5.x kernel are not working)

### Update Note  :warning: 
For Loader before 3.1.0 (also for Beta):
- It will be like a complete rebuild of Arc -> Replace Bootimage and reconfigure to get all working
- It is possible that the NIC are ordered different than before, best to remove the static ip before update
