[Impact]

 * LibreOffice 7.0.4 is in its fourth bugfix release of the 7.0 line:
     https://wiki.documentfoundation.org/ReleasePlan/7.0#7.0.4_release

 * Version 7.0.3 is currently released in groovy. For a list of fixed bugs compared to 7.0.3 see the list of bugs fixed in the release candidate (that's a total of 114 bugs):
     https://wiki.documentfoundation.org/Releases/7.0.4/RC1#List_of_fixed_bugs
     https://wiki.documentfoundation.org/Releases/7.0.4/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:
    https://ci.libreoffice.org/job/gerrit_linux_gcc_release/81006/

  * More information about the upstream QA testing can be found here:
    * Automated tests - https://wiki.documentfoundation.org/QA/Testing/Automated_Tests
    * Automated UI tests - https://wiki.documentfoundation.org/Development/UITests
    * Regression tests - https://wiki.documentfoundation.org/QA/Testing/Regression_Tests
    * Feature tests - https://wiki.documentfoundation.org/QA/Testing/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 114 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.
