### Upstream Changes ###

From https://github.com/ntamas/plfit/blob/master/CHANGELOG.md

"""
[0.9.4]
Fixed

  * Fixed a logical out-of-bounds access in the calculation of the Hurwitz zeta function, thanks to @jgmbenoit (#40)

  * Fixed the generation of libplfit.pc when CMAKE_INSTALL_<dir> is an absolute path.

  * Fixed an off-by-one indexing error in continuous fitting when x_min was selected using stratified sampling. This may have caused an out-of-bounds read on the input array in rare cases.

  * More rigorous memory cleanup in plfit_continuous() and plfit_discrete() in case of errors.

### Discussion ###

The s390x fix in the Ubuntu delta still appears to be relevant, given that the upstream bug (https://github.com/ntamas/plfit/issues/38) is still open, and none of the 0.9.4 changes deal with long double issues. Our fix has been forwarded to Debian (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1003395) although it doesn't appear to be showing as an issue in the Debian CI.
