I made a research on patches which were commited to a branch of LibreOffice but didn’t made it upstream. Thus I made a diff of the patch titles in this branch and the LibreOffice core master. I evaluated the branch distro/co-24.04 (https://github.com/LibreOffice/core/tree/distro/collabora/co-24.04) against the current state of the LibreOffice main branch (master). Thus I got a list of more than 6900 patch titles, which were not committed to the main branch of the LibreOffice project. I created a new file (from the current state of today) with those patch titles from the branch, which didn’t made it to the master: https://amantke.de/wp-content/uploads/2024/08/title-of-patches-in-co-24-not-in-lo-master.txt
I have not researched yet why this patched didn’t make it to the upstream project. But it’s worth to get at least through those patches since Oktober 2020, when Collabora decided to fork LibreOffice Online and moved it away to Github. I already found out in the past that patches for the LibreOffice Kit (LOK) wasn’t committed to the master branch and it needs some reminder to fix that.
