I’ve updated mongodb and mongo-tools from 3.4 to 3.6 in Bionic (LP: #1761807). They remain in universe.
As this is very late in the cycle, I took quite some care in testing things to detect any packaging regressions. I found none.
If you use mongodb at all, please help us by testing so that we can fix any issues before release if possible.
You can find mongodb 3.6 release notes here:
and compatibility changes for 3.6 here:
On upgrade from 3.4, mongod will remain in 3.4 compatibility mode by default, so from a distribution perpsective I believe this will be safe. Nevertheless, all testing is valuable and appreciated.
