KDE has released a first test version of the released that will be out this summer, in August. KDE SC 4.5.0 is targeted at testers and those that would like to have an early look at what's coming to their desktops and netbooks this summer. KDE is now firmly in beta mode, meaning that the primary focus is on fixing bugs and preparing the stable release of the software compilation this summer.
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 released 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.
Please test this release, and inform us of issues with the software through bugs.kde.org.
