Outdated bounds on hslogger?!

I just had a little dependency issue with hslogger:

[__3] rejecting: hslogger-1.3.1.0 (conflict:
base==4.14.3.0/installed-4.14.3.0, hslogger => base>=4.3 && <4.14)

The weird thing is that this bound is outdated since 2020-04-09, when a first revision was made to this hslogger version:

Why doesn't head.hackage simply serve the latest revisions?
