Sven, can we remove the older, vulnerable versions?

> Sven, can we remove the older, vulnerable versions?

we're still missing mips keywording, 0.8.12 is the last stable mips version.
Comment 12 Robert Buchholz (RETIRED) gentoo-dev 2009-07-05 10:24:00 UTC
MIPS has dropped stable support, you can simply remove that old stable ebuild and remove stable keywords from all that depends on it. Adding MIPS team to confirm this.
Comment 13 Ihar Hrachyshka 2009-09-01 12:28:24 UTC
Any reason to have vulnerable ebuilds in tree?
Comment 14 Sven Wegener gentoo-dev 2009-09-09 13:17:56 UTC
I've removed them, dropping the mips stable keyword.
Comment 15 Robert Buchholz (RETIRED) gentoo-dev 2009-09-10 00:06:04 UTC
still the glsa that needs to be sent, it's already in the queue
