Although most of the actions are taking place in Ubuntu 11.04 Natty Narhwal, Ubuntu 10.04 is still a very important release. Being an Long Term Support (LTS) release, it is widely used by those who prefer stability to new features and on servers where stability is very critical.
Canonical is committed to supporting Ubuntu 10.04 till April 2013 on desktops and April 2015 on servers. So, in continuation of the support, they have made available a new maintenance release of Ubuntu 10.04. The new release – Ubuntu 10.04.2 – is the second maintenance release of Ubuntu 10.04.
Since this is a maintenance release, it does not come with any new features. However, it does include a number of security updates and bug fixes which affected the release earlier. One of the most critical bug fixed in this maintenance release is are the installation bugs. The bug in the installation process which caused performance regression on ext4 file-systems has been fixed in this maintenance release.
This is what Kate Stewart, Ubuntu Release Manager, wrote in the mailing list:
Numerous updates have been integrated, and updated installation media has been provided so that fewer updates will need to be downloaded after installation. These include security updates and corrections for other high-impact bugs, with a focus on maintaining stability and compatibility with Ubuntu 10.04 LTS.
