xbps-0.16 (???):
* libxbps: change the order in which package files are removed:
current: files, conf_files, links, directories.
previous: links, files, conf_files, directories.
This is required to avoid removing working symlinks, which could be
owned by another installed package. Now only dangling symlinks are now
removed.
* libxbps: when removing package files and if metadata files.plist wasn't
found, do not error out and rather just continue until the package is
fully removed.
