It’s not an update, it’s a patch. Only updates have new content, next update is 1.2. Anything released before will be a patch.
ETA for 1.2: Currently, the Developers of Insurgence are holding their tongues on an update release date in order to not give the audience expectations of when 1.2 should come out. The only confirmation that we can give is the core devs plan to be finished with Insurgence Content as soon as possible. Updates regarding progress sometimes will be posted on either the devs’ twitter or on discord sometimes.
