R Snippets / Rserve version warnings

Dear Knime community,

can you tell me, since when R scripting nodes are relying on package Rserve? Has something changed in the shorterm or haven’t I just been aware R snippets were allwas using Rserve?

Moreover, I am experiencing warnings stating that all Rserve versions below or equal to 1.8.6 aren’t optimal (in other words buggy) for deploying R Snippet Nodes. That happened to me with several KNIME versions (3.5x and 3.6.1) Unfortunately there is no newer version of Rserve than 1.8-5, unless I missed on something here.

I’d be happy, if somebody could elaborate briefly on this topic or share potential fixes.

Thanks in advance,datastic
