§Kapitel 1. Hinweise zum Update
§1.1. Ablösung von Windows NT DC Funktionalität
§1.2. UCS-Installations-DVDs nur noch als 64-Bit-Variante
§1.3. Standard-Druckertreiber für PDF-Drucker
Ab UCS@school 4.0 R2 wird während einer Neuinstallation beim Anlegen des PDF-Druckers für die Druckmoderation automatisch der Windows-Druckertreiber MS Publisher Color Printer mit der Druckerfreigabe verknüpft. Dieser Treiber ist bei vielen Windows-Versionen bereits vorinstalliert (win7, win8.1, ...) und vermeidet so das unnötige Herunterladen und Installieren von Druckertreibern beim Verbinden mit der Druckerfreigabe. Falls ein abweichender Treiber gewünscht ist, kann dieser über die Univention Configuration Registry-Variable ucsschool/printermoderation/windows/driver/name angegeben werden.
Auf UCS@school-Systemen, die auf Version 4.0 R2 aktualisiert werden, wird der Druckertreiber nicht automatisch gesetzt. Falls auf einzelnen Systemen die Treiberzuordnung nachträglich ausgeführt werden soll, kann das Skript /usr/share/ucs-school-umc-printermoderation/set-windows-driver-for-pdf-printer auf dem jeweiligen System als Benutzer root ausgeführt werden.
§1.4. Gleichzeitiges Hochladen mehrerer Dateien
UCS@school unterstützt ab UCS 4.0 Errata-Stand 162 das gleichzeitige Hochladen von mehreren Dateien in den UMC-Modulen Klassenarbeit starten und Material verteilen, sofern dies auch vom verwendeten Browser unterstützt wird. Der Benutzer kann nun im Dateiauswahldialog seines verwendeten Browsers mehrere oder alle Dateien eines Verzeichnisses auswählen und diese in einem Schritt hochladen.

Die Changelogs mit den detaillierten Änderungsinformationen werden nur in Englisch gepflegt. Aufgeführt sind die Änderungen zwischen den UCS@school-Versionen 4.0 v2 und 4.0 R2 v1. Die Änderungsinformationen für vorherige Versionssprünge finden sich unter http://docs.univention.de/.
§5.1. Squid
A Squid ACL exception, to allow Windows Update to function with proxy authentication, is added during installation of ucs-school-webproxy (Bug 37541).
ucs-school-webproxy contains the scripts /usr/share/ucs-school-webproxy/set-java-updater-acl-exception and /usr/share/ucs-school-webproxy/remove-java-updater-acl-exception, to add/remove HTTP-User-Agent-header based filters, to allow the Java Updater to function with proxy authentication (Bug 37541).
ucs-school-webproxy contains the scripts /usr/share/ucs-school-webproxy/set-java-applet-acl-exception and /usr/share/ucs-school-webproxy/remove-java-applet-acl-exception, to add/remove HTTP-User-Agent-header based filters, to allow Java Applets to function with proxy authentication (Bug 37542).
External blacklists (e.g. for blocking adult content) may now be included in the squidGuard/squid configuration. These blacklists have to be placed as text file within the directory /var/lib/ucs-school-webproxy/ or any subdirectory. They may be included via the UCR variables proxy/filter/global/blacklists/domains and proxy/filter/global/blacklists/urls (Bug 30184).
§5.2. Univention Management Console
§5.2.1. Wizards (Users/Classes/Computers/Schools)
It is now possible to delete more than one school at once (Bug 36276).
The administrative and educational school servers are now shown in the table view of the Schools module (Bug 38200).
Containers, that are generated during school creation, are now added automatically to the list of default containers (Bug 35272).
§5.2.2. Computerroom
A racing condition in libitalc has been fixed that could lead to faulty behaviour of the UMC modules Computer room and Start exam (Bug 38413).
§5.2.3. Assign classes
A new module Assign classes has been added which can be used to assign one teacher to multiple classes. The module Assign teachers to classes has therefore been renamed into Assign teachers (Bug 32332).
§5.2.4. Exam
The workflow of starting an exam has been revised (Bug 38224).
It is now possible to select single computers for reboot when starting a exam (Bug 38004).
Invalid input is now validated when switching to the next page (Bug 37992).
A displaying error in the description of the Univention Configuration Registry variable ucsschool/ldap/default/groupname/exam has been fixed (Bug 37867).
Offline clients do not block the start of an exam anymore (Bug 37268).
The attribute memberUid for computers at the exam group OU${OU}-Klassenarbeit is now handled correctly (Bug 36251).
§5.2.5. Distribution
The first possible start times for automatic distribution and collection have been adjusted. Start times now have to be at least 1 minute in the future (before: 5 minutes). (Bug 38195).
The read permissions of students' home directories have been fixed (Bug 37854, Bug 38196).
The position of the file upload label has been adjusted (Bug 38159).
It is now possible to upload several files at once when distributing teaching materials. This requires erratum 162 of UCS 4.0-1 to be installed (Bug 32331).
§5.2.6. Helpdesk
The format of mails that are sent to the helpdesk team have been adapted. It now contains the full username and contact details (Bug 38198).
The users primary mail address is now used as sender address of helpdesk mails (Bug 37593).
The encoding of helpdesk mails have been set to UTF-8 to support unicode characters (Bug 36739).
Newline characters are now properly escaped in email headers (Bug 29975).
§5.2.7. Printer moderation
Print jobs from users with uppercase characters in their username are now correctly shown (Bug 34934).
A base directory restriction to the configured printer directory has been added (Bug 38270).
The windows printer driver for the PDF printer is now set to MS Publisher Color Printer by default (Univention Configuration Registry variable ucsschool/printermoderation/windows/driver/name). This driver is pre-installed on many versions of the windows operating system (win7, win8.1, ...) and therefore no driver download is necessary when connecting to the printer from a windows client (Bug 38201).
The PDF printer windows driver is only set during the first join of the printer moderation module. This can also be done manually by executing the script /usr/share/ucs-school-umc-printermoderation/set-windows-driver-for-pdf-printer.
§5.3. Other changes
Several updates have been performed in the UCS@school administrator manual and in the UCS@school teacher manual (Bug 38294, Bug 38363, Bug 38436).
Three new UCS@school related SDB articles have been published: SDB 1325, SDB 1326 and SDB 1327 (Bug 38197, Bug 38390).
