Nim versions 2.2.0 and 2.0.10 released

02 October 2024 The Nim Team

The Nim Team is happy to announce two releases:

version 2.2.0, our new stable release
version 2.0.10, a patch release for Nim 2.0

Nim v2.2.0 is a continuation of our efforts to improve Nim 2: it contains almost 1000 new commits, bringing improvements to the ORC memory management and to the language and the compiler overall.

Nim v2.0.10 is a patch release aimed at our enterprise users who cannot immediately switch to Nim 2.2, containing 80 commits with bugfixes.

Nim 2.2.0

Release highlights

Many long-standing compiler bugs with generics, typedesc and static types have been fixed in this release, effectively making these features stable. In particular, arbitrary expressions for types and values in generic types are now largely functional when they only worked in specific cases before. The release has a focus on bugfixes in general, with many other issues fixed across the board.

This release continues with the improvements regarding C++ interop:

noInit can be used in types and fields to disable member initializers in the C++ backend.
C++ custom constructors initializers.
member can be used to attach a procedure to a C++ type.
C++ constructor now reuses result instead creating this.

JS backend now supports lambda lifting for closures and closure iterators.

Methods now support implementations based on a VTable by using --experimental:vtables. Methods are then confined to the same module where their type has been defined.

Tuple unpacking got a bit more powerful:

Tuple unpacking assignment now supports using underscores to discard values.
```
var a, c: int
(a, _, c) = (1, 2, 3)
```

Tuple unpacking variable declarations now support type annotations, but only for the entire tuple.

let (a, b): (int, int) = (1, 2)
let (a, (b, c)): (byte, (float, cstring)) = (1, (2, "abc"))

An experimental switch --experimental:openSym has been added to deal with issues with symbol captures inside generic routines & templates. For macro authors, this adds a new node kind nnkOpenSym that may need to be handled differently (similar to nnkOpenSymChoice). See the full changelog for details.

Nim 2.2.0 ships with Nimble 0.16.1, which brings a SAT solver as an opt-in option.

For a full changelog, see here.

A complete list of changes is available here.

All bugfixes are listed at the bottom of this blogpost.

Installing Nim 2.2.0

Check out if the package manager of your OS already ships version 2.2.0 or install it as described here.

If you have installed a previous version of Nim using choosenim, getting Nim 2.2.0 is as easy as:

$ choosenim update self
$ choosenim update stable

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.

Alternatively, you can download Nim 2.2.0 from our nightlies builds.

Nim 2.0.10

A complete list of changes in Nim 2.0.10 is available here.

Installing Nim 2.0.10

If you have installed a previous version of Nim using choosenim, getting Nim 2.0.10 is as easy as:

$ choosenim update self
$ choosenim 2.0.10

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.

Alternatively, you can download Nim 2.0.10 from our nightlies builds.
