Lemmy.world is still on 0.17.4, which is the latest stable version.
0.18 isn't even out yet, interestingly. Only the release candidates are out: https://github.com/LemmyNet/lemmy/tags
lolwut, that's bizarre it's not letting me use it unless they messed something up.
I guess lemmy.ml is currently on 0.18.0-rc.6. Maybe lemmy.world should upgrade? I dunno.
There's some more info here: https://lemmy.ml/post/1446622 (maybe you can downgrade Jerboa)
Jerboa is running ahead and already targeting 0.18 API in their 0.0.35-alpha release.
Unfortunately this was not mentioned very prominently (or at least I did miss it) on github. F-Droid and Playstore still offer previous versions which work with lemmy <0.18.
Since Jerboa itself still needs many updates, I think it would be better to code against the latest stable lemmy release so that many people can use it for testing.
But I'm glad something like Jerboa exists at all, so thanks to the devs for all their work!
