Debian Lenny is frozen

What does the freeze mean and when can we expect Debian Lenny to be released? To answer the second question first, the release is currently expected in September. While the testing branch is very close to what Debian Lenny will be, there are still Release Critical bugs to squash and other work that must happen before Lenny is pronounced stable. This Debian "lenny" Release Information page gives some pointers to various progress pages where you can find out more about the bugs that still need to be fixed.

Mostly what the freeze means is that there are no more automatic uploads from Debian's unstable branch to the testing branch. Most Debian packages start out in unstable, also known as sid. That gives people a chance to test the packages and report any bugs. Assuming that these packages are working well, they will be automatically uploaded to the testing branch after a certain amount of time. Now though, testing is frozen, so a release manager will need to evaluate each unstable package and manually upload the package to testing, if it is judged suitable for Lenny. Chapter 5.13.3 of the Debian developers reference covers direct updates to testing, if you are looking for more detailed information.

When Debian releases a stable distribution the user can be assured that they are getting a very stable operating system. All the packages will interact well with one another. It will not be the most up-to-date system available, because stability is considered more important than new versions of packages. Many Debian users agree. Some will continue to run Etch, the current stable version, until several months after Lenny is released.

If you want a stable system, but need just one or two more current packages, you might consider building those packages yourself. Backports.org is another way of getting a few more current packages for your stable system. AptPinning allows you to run certain packages from one version, say unstable, on your stable system. There will be some risk with each of these methods, as newer packages may require newer libraries or have other dependencies. The more you change your stable system, the more instability you introduce.

The lenny package list will help you find out what packages are currently in Lenny. Some digging through the sections there will show that Lenny includes linux-image-2.6-486 (2.6.25+14), dpkg (1.14.20) and hal (0.5.11-2) are among the Administration Utilities. The Python section lists python (2.5.2-1) among the many related packages. To find out if Lenny has want you are looking for, just browse through the sections.
