Here is a quick list of new things around Scilab (note that it is slightly modified message of the one I sent on the dev mailing list).

• Sagemath - it is a software which combines the power of various opensource software.
  
  A Experimental "Scilab/Sage package" is planed for Sage 3.4 and an experimental package by Jaap Spies is already available

• Debian/Ubuntu
  Packages are available on my Scilab homepage
  Debian packages are up-to-date (5.0.3-2). I will to upload the new Ubuntu's packages in 2009 (for now, it is 5.0.3-1 which is working too). I might backport them to Debian Lenny (future stable) & Ubuntu Hardy.

• Mandriva
  Tomasz Pawel Gajc (a regular Mandriva contributor) created a package available on zarb.org

• Opensuse
  A Scilab package for Opensuse has been created by Andrea Florio.
  It is available on packman
  and should be included in the next version of opensuse.
  Note that Mandriva & Opensuse packages have been created for Scilab 5.0.3 and I applied most of their patches (or update some part of the code) for Scilab 5.0.4.

• Redhat/Fedora
  The work is still going on.
  They are also doing a great work packaging the misc dependencies but they are a bit stuck about the JOGL packaging (jogl and glugen should produce two different packages ... which I should also do in Debian/Ubuntu too)

• Arch Linux
  It is also available under Arch Linux by Simon Lipp (one of our former trainee).

• Gentoo
  A bit stuck for now but some activities have been seen lately around on jrosetta (one of the dependency introduced by Scilab 5).

• Slackware
  Scilab has been packaged by the Italian Slackware community. It is available on their website. I don't know if it is going to be included in Slackware by default or not;
