New features in Maverick
Feature development for Maverick has started. Please see the Maverick blueprint list for details.
As with every new release, packages--applications and software of all kinds--are being updated at a rapid pace. Many of these packages came from an automatic sync from Debian's Unstable branch. The period of automatic syncs has stopped now, so from now on there will be fewer changes.
The GNOME base platform has been updated to the current 2.31 versions. This particularly includes the new dconf and gsettings API. Evolution was updated to the 2.30 version, which operates much faster compared to the version in Ubuntu 10.04 LTS.
KDE was updated to the current 4.5 RC 1 release.
Qt was updated to the current 4.7 beta release.
The new Unity interface is now the default in Ubuntu Netbook Edition. This includes the global menu bar as part of the default interface. Please note that applications still retain the menu in their own window as long as the global menu bar is still being tested and fixed.
Linux kernel 2.6.35
Alpha 2 includes the 2.6.35-6.7 kernel based on 2.6.35-rc3.
This kernel includes new security enhancements. Of major note is the change the default behavior of PTRACE which is used by gdb, strace, ltrace, etc. The behavior for 10.10 is that only child processes can be PTRACEd, due to the default value of "1" in/proc/sys/kernel/ptrace_scope. This value may be inappropriate for some development systems and servers with only admin accounts. If using "sudo" for PTRACE is not desired, please change this value to "0".
New cloud-init features
cloud-init, the configurable initialization process for Ubuntu Server cloud images, has gained new features in Maverick Alpha 2, including pluggable hooks, ebsmount, ext4 support, and new stanzas in the cloud-config format.
The new btrfs file system may now be used during installation via manual partitioning, as long as /boot is on some other file system. (At the moment, this only works on the alternate and server CDs.)
When will one of these upgrade fix the long-standing and widespread problem that prevents so many from suspend/resume on a laptop?
I’ve been through three major version upgrades now in hopes of fixing that one issue. All of them have been painful, none has fixed it.
I have the same concern as Scott. I am not using Ubuntu 10.04 right now because of this suspend issue. I am hopping it will fixed on the next release.
