The Nim team is happy to announce version 1.4.8, our fourth patch release for Nim 1.4.

Version 1.4.8 is a result of one month of hard work, and it contains 23 commits, fixing the most important bugs and bringing additional improvements to our ORC memory management.

We would recommend to all of our users to upgrade and use version 1.4.8.

Release highlights

Just like our devel branch, v1.4.8 is built using csources_v1, which means you can use it on Apple M1 chips.
Version 1.4.6 triggered some false positives with several antivirus softwares. Based on our testing, this shouldn’t happen with v1.4.8.
Now you can use -d:release and -d:danger in your config files, no need to manually write these flags on the command line anymore.
Additional improvements to our ORC memory management. Use --gc:orc to compile your projects with it.

Installing Nim 1.4

New users

Check out if the package manager of your OS already ships version 1.4.8 or install it as described here.

Existing users

If you have installed a previous version of Nim using choosenim, getting Nim 1.4.8 is as easy as:

Alternatively, you can download Nim 1.4.8 from our nightlies builds.

Donating to Nim

We would like to encourage you to donate to Nim.

The donated money will be used to further improve Nim:

Bugs need to be fixed, the documentation can be improved, compiler error messages can always be better.
The most exciting upcoming feature, that has the greatest impact to all of our users, is incremental compilation.
Incremental compilation will also be the foundation for further tooling improvements like nimsuggest (autocompletion, find usages).
