Comment (by barracuda156):

 Replying to [comment:5 i0ntempest]:
 > I don't think there's an upper limit for boost version, but v58 being
 released before boost 1.81 may not be compatible. You can try.

 So Boost 1.81 seems to work, but the new `libfmt` does not, apparently:

 Did someone test this version or was it picked randomly?

 It may need to use an older version of libfmt.
