@Phantom:
Do you mean the SysSpeed "SystemInfo" subwindow? It says "WB: 45.5" here as expected. It also says "OS: 2.0 (45.57)" which is odd, but more likely indicative of a bug in SysSpeed than in version.library.
@honx:
See this thread for why it was removed:

If you install V1.37 on a system that already has V1.36, you will still have queue-handler 40.4 in L: You should overwrite it with V37.12 from eg. the OS3.9 CD.
