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.
Tarballs that join the KDE Applications release
Tarballs that were based on kdelibs4 and are now KF5 based
* kmix * kmouth * ksirk * palapeli * sweeper * zeroconf-ioslave * kde-dev-scripts (maybe not worth mentioning in the release notes)
Tarballs that we do not ship anymore
Tarballs that have changed contents
- kdeedu-data and ktuberling may show Perl as requirements due to few l10n-related macro for sr data files.
- dolphin, kgeography and step, due to few additional files and a regression in KI18n, fails for KI18n 5.34 and 5.35. See https://mail.kde.org/pipermail/release-team/2017-July/010424.html for more details.
