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').
These were added in libguestfs 1.14, but never really used. Only a
handful of probes were available. When I was benchmarking libguestfs
in 2016 I didn't even use these probes because better/simpler
techniques were available.
User-Mode Linux was an alternative hypervisor that could run the
appliance, instead of using qemu. It had many limitations including
lack of network, and UML support in Linux has been semi-broken for a
long time. It was also slower than KVM on baremeal in general and had
various corner cases which were much slower including the emulated
serial port which made bulk uploads and downloads painful. Also of
course it lacked qemu-specific features like qcow2 or any
network-backed disk, so many disk images could not be opened this way.
This was never supported in RHEL.

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.)
Create a new top level directory called 'utils' and move the
following programs there:
tests/qemu/boot-analysis -> utils/boot-analysis/
tests/qemu/boot-benchmark -> utils/boot-benchmark/
tests/qemu/qemu-boot -> utils/qemu-boot/
tests/qemu/qemu-speed-test -> utils/qemu-speed-test/
Also we only build the boot-analysis program on x86-64 and aarch64,
since it requires custom porting to each architecture.
Add a new test program called 'boot-benchmark'. This is similar to
'boot-analysis' but it simply boots and shuts down the appliance
several times in a row and measures how long it takes, calculating
mean and standard deviation.
