If you need to rectify info given in the subject, please do it by editing your question, and there the subject.
I gladly did it for you in this case.
Libreoffice 18.104.22.168 runs happily on my MBP 17" OSX 10.6.8. LibreOffice auto update function says there are no more updates.
I see there is a 22.214.171.124 but I haven’t tried it, and presume it is incompatible with 10.6.8.
