KDE community announced release of KDE Frameworks 5.13.0. This release contains a lot of improvements and bug fixes over previous releases.
According to a news article published in softpedia:
KDE Frameworks 5.13.0 has just been released by the KDE Community, and developers have made a large number of changes and improvements. KDE Frameworks is the backbone of the KDE project, but it's also the one that gets almost none of the glory. Everyone pays attention when the Plasma desktop is released, but we should give KDE Frameworks and KDE Applications the same treatment. Sure, it's difficult to spot the changes Frameworks is manifesting, but that shouldn't make you any less interested in what's happening under the hood.
