This bump requires a change to the exercises: replace uses of ArrayList
with array_list.Managed, to reflect the 2025-08-12 upstream change that
makes unmanaged the default [1].
From the corresponding PR [2]:
## Upgrade Guide
- std.ArrayList -> std.array_list.Managed
- warning: will be eventually removed from standard library
- std.ArrayListAligned -> std.array_list.AlignedManaged
- warning: will be eventually removed from standard library

It looks like Zig 0.15.0 won't be officially released [1]. [1] ziglang/www.ziglang.org@1be0f80b15d2

This PR is intended to stay as draft until the 0.15.0 release, at which point I'll update this PR to use plain
0.15.0.I'm just making this PR to get the tests passing in advance, and as the corresponding PR for exercism/zig-test-runner#127.
This should be an exciting release for Zig, because it's expected to make the x86_64 backend the default for debug builds. That'll speed up things a lot for both those using Exercism locally and in the browser.
See:
Edit 2025-07-31: The 0.15.0 milestone target date is now 2025-08-12.
Edit 2025-08-11: The 0.15.0 milestone target date was recently removed, and the number of open issues in the milestone has increased (there's currently 22 of them).
Edit 2025-08-19: The 0.15.0 release was tagged (see ziglang/zig@94cda37) and is being built.
Edit 2025-08-20: It looks like Zig 0.15.0 won't make it to a proper release (see ziglang/www.ziglang.org@1be0f80), and instead Zig will go straight to 0.15.1.
As a sample size of 1, the Linux workflow's testing step took:
main.So thats a roughly 4x speedup, which matches the speedup advertised above.
Closes: #342
To-do:
0.15.00.15.1 releaseexercism/zig-test-runneris ready to merge.Please let me handle merging this PR and the corresponding PR in
exercism/zig. Zig still makes a significant number of breaking changes, so the test runner and track repos should be kept in sync. My usual process is to merge the track PR as soon as I see that the new test runner image was successfully deployed.
