Preview build - I think there are some issues with that <pre> : http://web01.arangodb.biz/bugfix-3.4/mv-rocksdb-knownissue/Manual/ReleaseNotes/KnownIssues34.html

@sleto-it I have pushed an alternate formatting. Would you try generating the html again?

still broken (same link as before) - we could leave this to simran, i believe, should be easy fix for him

Literal line breaks are simply not supported in Markdown tables and there does not seem to be a way to escape literal line breaks. What does seem to work is an encoded line break 
.

So the full solution is: <pre>multiple&#13;lines</pre> | foo | bar

BTW. there was also a ] missing in [facebook/rocksdb#4983(https://github.com/facebook/rocksdb/issues/4983) before (.
Deployment Mode is only for the categories single server, master/slave, active failover, cluster, standalone agency. Should we add an Operating System line or something like that?
