Today KDE released updates for its Applications and Development Platform, the
first in a series of monthly stabilization updates to the 4.12 series.
Starting with the 4.12.2 releases, the KDE Workspaces 4.11.x releases will be
synchronized with those of KDE Applications and Development Platform 4.12.x.
This release contains only bugfixes and translation updates; it will be a safe
and pleasant update for everyone.

More than 45 recorded bugfixes include improvements to the personal
information management suite Kontact, the UML tool Umbrello, the document
viewer Okular, the web browser Konqueror, the file manager Dolphin, and
others. Umbrello standardizes the global, diagram and widget settings and
adds a clone diagram function. Dolphin gets a bug fixed that slowed down pdf
preview under certain circumstances. In Kontact, several bugs and regressions
were fixed in the KOrganizer, Akregator and KMail components.

A more complete list of changes can be found in KDE's issue tracker. For a
detailed list of changes that went into 4.12.1, you can also browse the Git
logs.
