No change log as this is a test build, needs testing by both 2 and 3 wire power supply users, note new menu setting Power Input, default is 2 wire, this will need to be changed to 3 wire for those with the 3 wire power supply
Will leave the link to the prior public release V1.32 below should you wish to roll back
Note that using beta firmware will NOT void your warranty, links to previous release versions are included in the notes should you want to roll back
