I think libreoffice does meet pretty well the requirements for microrelease exception. The only point I'm not sure about is whether the tests cover API/ABI stability, this should be researched and confirmed.
As stated in the description, upstream runs both automated and manual testing for each new micro release (and the corresponding release candidates). https://wiki.documentfoundation.org/QA/Testing/Regression_Tests has some information. Additionally the autopkgtests for the package are pretty extensive. We have a long history of SRUing libreoffice microreleases to LTSes, predating my taking over the maintenance of this package in 2017. I'll let Heather comment on the impact of bug #1869561 (its importance is set to High, if that's any indication). -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to libreoffice in Ubuntu. https://bugs.launchpad.net/bugs/1881007 Title: [SRU] libreoffice 6.4.4 for focal Status in libreoffice package in Ubuntu: In Progress Status in libreoffice source package in Focal: Incomplete Bug description: [Impact] * LibreOffice 6.4.4 is in its fourth bugfix release of the 6.4 line. Version 6.4.4 is currently in focal. For a list of fixed bugs compared to 6.4.3 see the list of bugs fixed in the two release candidates: https://wiki.documentfoundation.org/Releases/6.4.4/RC1#List_of_fixed_bugs https://wiki.documentfoundation.org/Releases/6.4.4/RC2#List_of_fixed_bugs (that's a total of 98 bugs) * Given the nature of the project, the complexity of the codebase and the high level of quality assurance upstream, it is preferable to SRU a minor release rather than cherry-pick selected bug fixes. [Test Case] * No specific test case, bugs fixed upstream hopefully come with unit/regression tests, and the release itself is extensively exercised upstream (both in an automated manner and manually) by a community of testers. Each minor release normally goes through two release candidates. * The libreoffice packages include autopkgtests, those should be run and verified to pass. * General smoke testing of all the applications in the office suite should be carried out. [Regression Potential] * A minor release with a total of 98 bug fixes always carries the potential for introducing regressions, even though it is a bugfix-only release, meaning that no new features were added, and no existing features were removed. * A combination of autopkgtests and careful smoke testing as described above should provide reasonable confidence that no regressions sneaked in.
