[Impact]

 * LibreOffice 7.1.4 is in its forth bugfix release of the 7.1 line:
     https://wiki.documentfoundation.org/ReleasePlan/7.1#7.1.4_release

 * Version 7.1.3 is currently released in hirsute. For a list of fixed bugs compared to 7.1.3 see the list of bugs fixed in the release candidates of 7.1.4 (that's a total of 79 bugs):
     https://wiki.documentfoundation.org/Releases/7.1.4/RC1#List_of_fixed_bugs
     https://wiki.documentfoundation.org/Releases/7.1.4/RC2#List_of_fixed_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.

[Testing]

 * Upstream testing. Bugs fixed upstream typically include unit/regression tests, and the release itself is extensively exercised (both in an automated manner and manually).

  * A recent set of upstream's automated jenkins testing can be found here:

  * More information about the upstream QA testing can be found here:

    * Feature tests

 * Launchpad testing. The libreoffice packages include autopkgtests that were run and verified as passing.

 * General smoke testing of all the applications in the office suite were carried out by going through the manual testplan as documented by: https://wiki.ubuntu.com/Process/Merges/TestPlans/libreoffice

[Regression Potential]

 * A minor release with a total of 79 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.
