According to a new article out of the organization, "The KDE Community is proud to announce the latest major updates to the KDE Applications delivering new features and fixes. Kontact (the personal information manager) has been the subject of intense activity, benefiting from the improvements to KDE's Semantic Search technology and bringing new features. Document viewer Okular and advanced text editor Kate have gotten interface-related and feature improvements. In the education and game areas, we introduce the new foreign speech trainer Artikulate; Marble (the desktop globe) gets support for Sun, Moon, planets, bicycle routing and nautical miles. Palapeli (the jigsaw puzzle application) has leaped to unprecedented new dimensions and capabilities."
The article adds, "Kontact performance is noticeably improved in this version. Some improvements are due to the integration with the new version of KDE’s Semantic Search infrastructure, and the data caching layer and loading of data in KMail itself have seen significant work as well. Notable work has taken place to improve support for the PostgreSQL database.
