Resolving conflicts

To resolve any conflicts, check out the temporary branch and run the following command:

git merge 4.3

Ignoring changes

To ignore from the remote branch, first reset the temporary branch to 4.3 and manually merge using the `ours` merge strategy:

git reset --hard 4.3
git merge --strategy=ours 4.2

Then, push the temporary branch to upate the pull request.

@jmikola It looks like the commits have been rebased before merge into 4.3 😱

[jmikola]

@GromNaN: I likely did rebase this before merging. I was somewhat distracted with the 1.18 releases, but IIRC the GitHub UI suggested doing so because the PR was out-of-date.

How devastating is this? Is a future auto-merge PR going to want to merge 4.2 again?
