Debian's proposed-updates Feature Mar 2, 2009, 19 :33 UTC (0 Talkback[s]) (4363 reads) (Other stories by Juliet Kemp)
"proposed-updates is the mechanism used to prepare the point (minor) releases of stable (lenny) and oldstable (etch, which will continue to be supported until about a year from now). Packages are added to proposed-updates either automatically (in the case of security updates from security.debian.org) or manually by developers. Once rigorously tested, they are released into the main stable repository."
