merging master (at 0.4.23) into 0.4 to form new 0.4

Changes in master should completely supersede those in release
branches, even if there have been hot fixes since the last
release. We'll use the 'ours' merge strategy to accomplish this, which
requires master branch to be the first parent of the merge. The merge
commit, however, will become part of the release branch, *not* part of
master.

This may be a bit confusing, but it ensures that changes made to
'master' branch by developers will be faithfully applied.
