I’ve got 2 servers :
A production one with LOOL and a development one with CODE.
The versioning is slightly different.
Is there a correlation table between versions ?
Example : CODE Server
Version COOLWSD : 21.11.2.4
Version LOKit :Collabora Office 21.06.20.1 LOOL Server
COOLWSD version: 6.4.17
LOKit version: Collabora Office 6.4-53
Great reply; we work hard to get all our core code-changes up-stream into LibreOffice - but since we have rather a different product with a different release cadence, we no longer use the LibreOffice version numbers. That changed with 21.11 - which is based on LibreOffice 7.1, but after some months is really its own branch with a separate collection of feature/function changes. Also some huge wins in performance / design / capability over 6.4.x.
When you say LOOL - do you mean COOL ? - if you have that, then you should just upgrade to the latest version by tweaking the version in the repo URL.
