There has been a release of Lemmy version 0.18.
There is a very long list of changes for the back end and front end. You can see them here: https://github.com/LemmyNet/lemmy/releases
I do plan to upgrade at some point. However, I'm considering waiting until Lemmy 0.18.1. In 0.18 they removed captcha support. This has been a very useful tool to keep bots from taking over the instance. If I upgraded to 0.18 now I'd have to turn on registration applications. I fear that the registration application would be too much friction to gain users.
Please, let me know what you think of this change. An announcement will be made once an upgrade is to take place.

I'm going to do the update now. It's running on several instances successfully.
