The following packages have been masked pending removal in 30 days (roughly):

kde-misc/kxdocker-configurator
kde-misc/kxdocker-i18n
kde-misc/kxdocker-dcop
kde-misc/kxdocker
kde-misc/kxdocker-trayiconlogger
kde-misc/kxdocker-resources

Reasons:
- no developed by upstream [1]
- no active maintainer [2]

These are still available in the xeffects overlay for those who want them [3].
