Almost 8 months after the release of v0.19.0, here is the third bugfix release:
https://nim-lang.org/blog/2019/05/13/version-0196-released.html
If you use choosenim, the new version is just choosenim update stable away, otherwise follow the instructions from here.
And for the first time, Nim is now Manjaro package and v0.19.6 has just hit Manjaro Stable.
(Until two days ago it was dependent on Archlinux Nim package, which is still at version 0.18.0, regardless of outdated flag and repeated mails to the maintainer)
