Nim versions 2.2.4 and 2.0.16 released

[NewsBot]

A new Nim blog post/announcement has been posted!

The Nim Team is happy to announce two releases:

• version 2.2.4, a second patch release for the latest stable version
• version 2.0.16, an eight patch release for Nim 2.0

Nim v2.2.4 comes two and a half months after the v2.2.2 release and it contains 108 commits bringing bugfixes and improvements.

If you’re still using Nim v2.0, the v2.0.16 release brings 31 commits with bugfixes. But we would encourage you to switch to Nim v2.2, as it brings significant improvements to the ORC memory management and to the language and the compiler overall.
Here is the version 2.2 release article, showing the improvements available in Nim 2.2.

The Nim 2.2.4 changelog is available here.

Installing Nim 2.2.4

Check out if the package manager of your OS already ships version 2.2.4 or install it as described here.

If you have installed a previous version of Nim using choosenim, getting Nim 2.2.4 is as easy as:

$ choosenim update self
$ choosenim update stable

NOTE: Make sure that the version of choosenim you have installed is 0.8.5 or higher, otherwise visit choosenim’s repo and see there how to re-install it first, before updating Nim.
