K Desktop Environment 3.0
K Desktop Environment 3.0 introduced better support for restricted usage, a feature demanded by certain environments such as kiosks, Internet cafes and enterprise deployments, which disallows the user from having full access to all capabilities of a piece of software, in order to preclude certain undesirable actions. To address these needs, KDE 3.0 included a new lockdown framework, essentially a permissions-based system for altering application configuration options that supplements the standard UNIX permissions system. The KDE panel and the desktop manager were modified to employ this system, but other major desktop components, such as Konqueror and the Control Center, had to wait for subsequent releases.
K Desktop Environment 3.0 debuted a new printing framework, KDEPrint. KDEPrint's modular design enabled it to support different printing engines, such as CUPS, LPRng, and LDP/LPR. In conjunction with CUPS, KDEPrint was able to manage an elaborate enterprise networked printing system. Since KDEPrint provides a command-line interface, its framework, including its GUI configuration elements, is accessible to non-KDE applications, such as OpenOffice.org, the Mozilla Application Suite, and Acrobat Reader.
This release also introduced a new KDE address book library providing a central address book for all KDE applications. The new library is based on the vCard standard and has provisions for being extended by additional backends such as LDAP and database servers.

Famous quotes containing the word environment:
“For those parents from lower-class and minority communities ... [who] have had minimal experience in negotiating dominant, external institutions or have had negative and hostile contact with social service agencies, their initial approaches to the school are often overwhelming and difficult. Not only does the school feel like an alien environment with incomprehensible norms and structures, but the families often do not feel entitled to make demands or force disagreements.”
—Sara Lawrence Lightfoot (20th century)
