Connie Sieh, Troy Dawson, Jaroslaw Polok and the entire developers team behind the Scientific Linux project are proud to announce the SL version 4.5 for the i386 architecture. Scientific Linux release 4.5 is based on the rebuilding of RPMS out of SRPMS's from Enterprise 4 AS, including Update 5.

Even though this release came a bit later than it was initially estimated, this aspect can be ignored as this version brings plenty of changes, corrections and bug-fixes. Also Scientific Linux 4.5 cannot be used as a Xen virtual host but at least it can now be installed as a Xen paravirtual guest, a fact that should provide a significant speed increase over fully virtualized guests.

Highlights:

- upgraded stable branch of openafs (version 1.4.4)
- useful perl modules added (perl-Compress-Zlib-1.16-12.i386.rpm, perl-SQL-Statement-1.06-1.noarch.rpm, perl-MailTools-1.62-1.noarch.rpm)
- yum repository (however this does not implies also the fact that this is compatible with all other SL 4.4 yum repositories)
- dropit - removes directory entries from a PATH shell variable value, which has colon separated fields(it is usable in sh, ksh, and csh shell script files)
- FUSE - makes it possible to implement a fully functional filesystem in a userspace program
- Firmware for the Intel� PRO/Wireless 2100 and 2200 Driver
- java-1.4.2-sun-compat-1.4.2.12-1jpp.i586.rpm - provides Jpackage compatibility symlinks and directories for Sun's JDK rpm
- madwifi - with support for Atheros G wireless
- multimedia - updated to latest version

As a follow of a bug-fixing the Sl 4.1 and SL 4.2 versions seem now incompatible. Therefore if you have to upgrade from SL 4.0 and 4.1, you have to update your cluster at once. Built up of some source packages belonging to Red Hat Enterprise Linux and fully compatible with it, SL also brings up some new additions which address mainly the users from the scientific community.

Few additions: Scientific Linux has the 2.6.9-55 kernel (Red Hat patched/customized) and the 3.4.6 version of gcc. For those using laptops, the repositories contain the ndiwrapper kernel modules. It might sound strange such a piece of news about Scientific Linux 4.5, but you'd be suprised to find out how many people are still using SL 3.0.x or are still struggling to migrate to SL 4.5 ;) !
