KDE Software Compilation 4.5 RC1 Release Announcement

Sunday, 27 June 2010


KDE Software Compilation 4.5 RC1 Released: Codename Coppu

KDE Community Ships First Release Candidate of the 4.5 Free Desktop, Applications and Development Platform

Today, KDE delivers the first release candidate of the upcoming KDE Software Compilation 4.5. The final version will be available in August 2010 and this RC is intended for testers and early adopters who can help by finding and reporting bugs. It will also interest those who want an early look at what is coming to their desktops and netbooks this summer.

The KDE Community continues to fulfill the promise of delivering state of the art architecture with its Development Platform. The Applications in Software Compilation 4.5 take advantage of this, introducing improvements across the board in terms of innovative new features, greater ease of use, accessibility, good looks, better networking and further internationalization.

With the start of the release candidate cycle, the development community focusses on bug fixing and polishing in preparation for the final release while the translators finish the last texts. Since beta 2, 1233 bugs have been reported and 1165 have been closed, a sign of the hard work by the developers (and the bug triaging team) to create a solid final release.

KDE SC 4.5 sports many improvements, among which are:

Initially planned for KDE SC 4.5.0, the KDE PIM team have decided to delay the release of the Akonadi-based KMail for one month. The new version of KMail will be delivered as part of one of KDE's monthly bugfix updates. In the meantime, the stable version of KMail from KDE SC 4.4 will be maintained. Akonadi will centralize syncing and caching of PIM data, deliver wider support for groupware servers and makes handling PIM data, such as contacts, calendaring and email more efficient by sharing it across applications.

To find out more about the KDE Plasma desktop and applications, please also refer to the 4.4.0, 4.3.0, 4.2.0, 4.1.0 and 4.0.0 release notes.
