2) ALS type: Arm Length Stabilization (ALS), Cavity Locking
3) MC type: Input Mode Cleaner (IMC) Cavity Locking
4) CM type: Interferometer Common Mode
5) SQZ type: Squeezer boards (SHG, OPO, LO and CLF locking)

v6 incorporates the following changes:
- Accounts for the new ETMs which fix the green coating error (ALS)
- Introduces the SQZ variant

The PCB has not changed and is still at revision E.
