What is the latest compatible pair of Litecoin Core node + p2pool node? Do these pairs support SegWit?

Official p2pool.in reports latest version 17.0 server, but many pool operators show the presence of versions much higher,
like

77.0.0-8-g4b1cc42-dirty
33.0-4-gf7b5fba-dirty
and others...

Where to get it for my own node?
