Run this command across the source:
perl -pi.bak -e 's/(20[012][0-9])-20[12][012]/$1-2023/g' `git ls-files`
and remove changes to po{,-docs}/*.po{,t} (these will be regenerated
later when we run 'make dist').
This was a feature that allowed you to add drives to the appliance
after launching it. It was complicated to implement, and only worked
for the libvirt backend (not "direct", which is the default backend).
It also turned out to be a bad idea. The original concept was that
appliance creation was slow, so to examine multiple guests you should
launch the handle once then hot-add the disks from each guest in turn
to manipulate them. However this is terrible from a security point of
view, especially for multi-tenant, because the drives from one guest
might compromise the appliance and thus the filesystems/drives from
subsequent guests.
It also turns out that hotplugging is very slow. Nowadays appliance
creation should be faster than hotplugging.
The main use case for this was virt-df, but virt-df no longer uses it
after we discovered the problems outlined above.
As part of our efforts to clean up and simplify libguestfs, removing
gnulib deletes a large dependency that we mostly no longer use and
causes problems for new users trying to build the library from source.
A few modules from gnulib are still used (under a compatible license)
and these are copied into gnulib/lib/
Only in end-user messages and documentation. This change was done
mostly mechanically using the Perl script attached below.
I also changed don't -> don’t etc and made some other simple fixes.

Run the following command over the source:
perl -pi.bak -e 's/(20[01][0-9])-2016/$1-2017/g' `git ls-files`
(Thanks Rich for the perl snippet, as used in past years.)
