(Sorry for the inconvenience)

The following features have been added to or improved for PC-BSD® 9.1:

  • Based on FreeBSD 9.1, which includes improved Intel video support. The Release Notes for FreeBSD 9.1[1] list the new features and drivers introduced in FreeBSD 9.1.
  • The PC-BSD® installer has been revamped to separate pre-installation tasks from post-installation tasks. This makes it easier to automate the roll-out of multiple installations because the end-user can configure their account information and display settings before logging in for the first time.
  • The PC-BSD® installer now sets its default settings according to the hardware installed. 64-bit systems containing over 2GB of RAM will default to the ZFS filesystem whereas 32-bit systems and any system containing less than 2GB of RAM will default to UFS+SUJ. Systems containing more than 2GB of RAM will default to the KDE desktop and all other systems will default to the LXDE desktop. A hardware compatibility icon within the installer allows the user to see at a glance if their video card, Ethernet card, wireless card, and sound card are compatible with PC-BSD®.
  • The ability to perform a network install has been removed from the graphical installer. The scriptable back-end still provides the variables needed for network installations.
  • The ZFS section of the PC-BSD® installer now allows you to set ZFS properties such as compression and quotas, create datasets, and import existing ZFS pools.
  • Multiple Boot Environments support allows systems formatted with ZFS to create alternate bootable snapshots. These can be used for testing purposes or to create a bootable backup of the boot environment before performing an upgrade.
  • Warden® is now built into the operating system and available through Control Panel. It can now be used to manage multiple jails.
  • Warden® now supports the creation of three types of jails: traditional FreeBSD jails for running network services, (a less secure) ports jail for safely installing and running FreeBSD ports/packages from your PC-BSD® system, and the installation of Linux within a jail.
  • Warden® now supports the management of ZFS snapshots on a per-jail basis.
  • Update Manager has been integrated into Warden®. Combined with the meta-package support, it is now easier than ever to install software into a jail and to keep that software up-to-date.
  • AppCafe® now shows the number of available PBIs and supports automatic updating.
  • EasyPBI is now available through Control Panel, making it easier than ever to convert existing FreeBSD ports to PC-BSD® PBIs.
  • An About icon has been added to the Control Panel, making it easy to determine the PC-BSD® version, which desktops, and the version of X that have been installed.
  • An Active Directory & LDAP GUI has been added to Control Panel, allowing you to set the client information for connecting to Active Directory servers.
  • A Hardware Compatibility icon has been added to the control panel, providing a quick overview of detected hardware devices.
  • The GDM Configuration GUI has been added to Control Panel and can be used to configure auto-login and remote login through XDMCP.
  • A Mount Tray icon has been added to the Control Panel and System Tray, allowing easy access to USB drives.
  • A Sound Configuration icon has been added to the Control Panel and can be used to test sound or change the default audio device.
  • Life Preserver now provides a browse button when creating an include or exclude filter.
  • Thin Client now allows you to create a PXE Boot Desktop Server or a PXE Boot Installation Server.
  • When ZFS formatting during installation, gnop 4K alignment[2] is now used when creating the zpool. This results in a dramatic increase in performance. For this reason, it is recommended that users with existing ZFS installations re-install rather than upgrade in order to receive these performance benefits.
