I do that for two reasons: first, because I'm the maintainer of the package in Debian, and Debian Etch has GForge 4.5, and Etch is supported for security fixes; second, because I also admin/maintain an instance for a client of mine, so I need to backport the fixes anyway, and making them public is no bother. Both of these reasons are going to vanish sometime in the not too distant future: security support for Etch will end in February, 2010, and I hope to have migrated my client's forge to FusionForge 4.8 by then too.
Je saisis donc l'occasion pour apporter quelques rectifications à cet article de Yann Serra.
