IOS37 fixed the signing bug, and this fix has been added to all other IOSes. This IOS is used by several WiiWare games, and older Guitar Hero/Rock Band games.
IOS37 was most likely forked from IOS35v1040, since many of IOS36's modules are on the Release/apricot-win/SDK_FW_36_4_18_branch branch, while the corresponding IOS37 modules are on the Release/apricot-win/SDK_FW_30_4_13_branch branch, similar to IOS35.
It is also one of four IOSes not fixed in 3.3rev03, and instead had its ES_Identify and /dev/flash fixed in 3.4. The other IOSes not fixed at this time were IOS30, IOS31, and IOS16 (not fixed until 4.0)
