All Shift Light circuit boards (those sold separately, in the DIY kits, and the assembled kits) have an updated design revision v2.41. This revision corrects an error with v2.4 by adding a new trace, so a manual jumper from pins D2 and D8 is no longer required. v2.41 also has some additional labeling on the silk screen to aid in assembly.
The arrival of these new boards means kits are restocked and available for purchase in the online store. More news coming soon. :)
