Since 17.04, the translations (messages, translated documentation, localized data) are included in the tarballs but *only* for Frameworks 5 applications.
Also, since this release does not contain anymore kdelibs4-based tarballs, there are no kde-l10n* tarballs as well. They used to contain only translations for kdelibs4-based tarballs starting from 17.04, so they are not needed anymore.
* juk * kimagemapeditor * kget * kmix * kmouth * kolf * ksirk * palapeli * sweeper * zeroconf-ioslave * kde-dev-scripts (maybe not worth mentioning in the release notes)
* kdelibs (4.14.x) * libkface (was unmaintained and didn't compile against newer opencv) * blogilo (too broken, needs someone to step up and fix it and then it can rejoin) * jovie (replaced by Qt Speech) * kaccessible (superseded by the bridge from the Qt accessibility API to At-Spi provided by Qt5) * ksaneplugin (not used even during kdelibs 4.x times) * kde-runtime (was kdelibs4-based split into various other repos for kf5-based counterparts) * kremotecontrol (was not ported to KF5) * kppp (was not ported to KF5) * kfilereplace (was not ported to KF5) * klinkstatus (was not ported to KF5) * kopete (was not ported to KF5) * kscd (was not ported to KF5) * kstars (moves to released independently)
