It has a newly inducted ‘Paid Apps’ section, a ‘Where is it?’ feature for locating applications after install, he ability to select add-ons to be installed alongside popular applications as you install them and, most notably, a sublime new look.
As is to be expected at this stage of the release process, there are several known bugs that users are likely to run into with Maverick Beta. We have documented them here for your convenience along with any known workarounds, so that you don't need to spend time reporting these bugs again:
・ The Gwibber micro-blogging client has switched to SQLITE for back end storage. This should make it faster, but means that syncing of account details across computers is no longer supported. Also note that due to a change to the Twitter service, Gwibber will not work with Twitter until updates are applied.
・ The Wubi Windows installer was reported to be unable to open Windows' boot configuration data store in some (but not all) cases. Investigation of the problems are ongoing (613288)
・ Upgrading Wubi systems from 10.04 LTS is known to fail, and is not recommended at this time. (610898, 617715)
・ Ubuntu Netbook Edition with Unity does not currently provide a fallback for systems without a 3D capable video driver, such as NVidia cards. (600567)
・ On systems with very little memory (256 MB and below), ureadahead causes out-of-memory conditions, which may break booting. (600359)
・ Maverick thumb drive images built on Lucid (& earlier?) fail to boot due to differences in syslinux version - the 'ui' keyword in the syslinux.cfg file needs to be removed to get it to boot. A fix for this on Lucid is available to be applied, see lucid-updates. (608382)
・ A lot of USB 3G cards currently just expose themselves as a CD drive instead of a modem. To fix this, please upgrade your system to get udev version 161+git20100827-1, which should fix this. (625110)
・ Inconsistent certificates prevent CC to start correctly (627963). On affected systems, you don't get anything in /var/log/eucalyptus/cc.log. This is an inconsistent issue that is not being reliably reproduced yet, and is actively being worked on: see on the bug for the best workaround known.
・ eucalyptus-get-console-output will not display the instance console log (619843). This is due to a change in the user libvirt uses. Performing a "sudo adduser eucalyptus kvm" should resolve this. Closely following beta release, a fix will be uploaded.
・ There are still some issues with upgrading Eucalyptus from Lucid to Maverick Beta (617053). Shortly following Beta release, a standard upgrade should resolve this issue.
・ Known major issues for Kubuntu:
・ The live CD "Guided" install option replaces the existing operating system installation in the selected partition (including destroying user data). This is not obvious from the description. See Bug (628864) for details.
・ The live CD autoresize installation option is not always available (see Bug (628897) for details). To work around this issue, do any needed partition resizing before starting the live CD. Partitions can be deleted and created using the manual partioning option if no data needs to be saved from them.

・ 613636 Kubuntu Maveric ISOs show purple "Ubuntu 10.10" boot splash
・ 628681 Kubuntu OEM did not install oem-config-kde

The new btrfs file system may now be used during installation via manual partitioning, as long as /boot is on some other file system.
