KDE SC 4.9 RC2 發布
KDE，K桌面環境(Kool Desktop Environment)的縮寫。一種著名的運行于 Linux、Unix 以及FreeBSD 等操作系統上面自由圖形工作環境，整個系統采用的都是 TrollTech 公司所開發的 Qt 程序庫（現在屬于諾基亞公司）。KDE 和 Gnome 都是 Linux 操作系統上最流行的桌面環境系統。
KDE SC 4.9 RC2 發布了，還將會有另外一個 RC 版本后推出正式版。RC2 繼續修復發現的問題。
官方關于 KDE SC 4.9 RC2 的發行說明：Today KDE released the second release candidate for its Workspaces, Applications, and Development Platform. With API, dependency and feature freezes in place, the KDE team's focus is now on fixing bugs and other polishing. Highlights of 4.9 will include:
- Qt Quick in Plasma Workspaces. Qt Quick continues to make its way into the Plasma Workspaces. The Qt Quick Plasma components, which were introduced with 4.8, mature further. Additional integration of various KDE APIs was added through new modules. More parts of Plasma Desktop have been ported to QML. While preserving their functionality, the Qt Quick replacements of common Plasmoids are more attractive, easier to enhance and extend and behave better on touchscreens.
- The Dolphin file manager has been improved in its display and sorting and searching based on metadata. Files can now be renamed inline, giving a smoother user experience.
- Deeper integration of Activities for files, windows and other resources. It is now easier for users to associate files and windows with an Activity, and enjoy better Workspace organization. Folderview can now show files related to an Activity, making it easier to organize files into meaningful contexts.
- Many performance improvements and bugfixes improve the overall user experience, making KDE Applications and Workspaces more productive and fun to use than ever before.
More improvements can be found in the 4.9 Feature Plan. There are many changes, so 4.9 needs a good testing in order to maintain and improve quality and to deliver an exceptional user experience.
Testing in Progress
As with earlier 4.9 releases, testing continues for the release candidate RC2.
The KDE Testing Team is collaborating directly with the developers of several KDE projects. There is also more work going on in collaboration with the KDE sysadmins to facilitate automatic testing for all KDE projects. Continuous integration is already used by several core components of KDE.
To join the KDE Testing Team, please come to the #kde-quality channel on irc.freenode.net or join the mailing list kde-testing@kde.org.
