It’s a really long topic … Everything start long, long ago … no wait … sorry (bad template).
To not make this comment too big I would just list my few hints, so everybody could find himself/herself more and more things:
- Of course nothing bad happen, so all things that we loved in previous years
- Review all erlang/otp changelog files since last thread like this one
- Review all elixir-lang/elixir changelog files since last thread like this one
- Browse all topics in #your-libraries-projects section
- Browse as more as possible (yeah we already have tons of it) libraries in hex
- Browse as more as possible (like in previous point) projects in Github, GitLab and other code hosting repository services
- Look at our adoption and media including blogs, video blogs and even paid learning
- Look how fast this community is growing and how much we help each other
and anyway you would be able to find even more cons in another ways … 
It’s just already too hard to list all things why I and others love this fantastic language!
