** Description changed: [Impact] * There are various issues that are fixed by the stable release of 4.2.1 Most prominently a bunch of memory leaks that will help long running instances to not get into trouble later on * There are also a number of CVEs covered, but those got added in a bigger security update of 1:4.2-3ubuntu6.4 just before this upload, so they are not "new" in 4.2.1 anymore for Ubuntu users. [Test Case] * Being a stabilization minor release there is no individual test to apply. Instead we will pass it through the full regression test suite and probably keep it some extra days in -proposed. * Openstack indirectly depends on this for bug 1891203, so I'll ask them if they can test this as well before we release it. [Regression Potential] * Naturally with so many changes it is hard to pinpoint the location of potential regression. But the changes were those meant to be non-count- impacting-fixes meant for a stable release and got some testing by the community already. [Other Info] * We will hold this longer in -proposed and do even more testing to make up for the remaining regression potential uncertainty - * This is a continuation of bug 1867519 which contained such changes that - were available prior to the focal release, but now upstream tagged - those and some more as v4.2.1 + * This is a continuation of bug 1867519 which contained such changes that + were available prior to the focal release, but now upstream tagged + those and some more as v4.2.1 + * This also fixes an issue in riscv emulation that was introduced in + recent security release of 1%4.2-3ubuntu6.4 by adding + https://git.qemu.org/?p=qemu.git;a=commit;h=70b78d4e71 --- Upstream has completed the 4.2.1 stable tag https://github.com/qemu/qemu/releases/tag/v4.2.1 Fixes are in groovy already via qemu 5.0 These are only non-feature backports, the majority this time being memleaks and bad accesses of some sort. Some of the patches are already present in Ubuntu's 4.2 as of today. But adding the others will serve the stability of our most recent LTS.
