@cecton

Could you please review this and release a new version with the updated dependency?
This is blocking yewstack/yew#3322.

[cecton]

doesnt seem to be much to review ^_^

[cecton]

@futursolo to avoid getting blocked like that again, do you mind if I add you to the crate owner?

[cecton]

Released in 0.3.7

[cecton]

@futursolo do you think we should relax the version to >= 1 and <= 2?

[cecton]

I have relaxed the dependency and yield the release 0.3.7 because I think it can cause issues for yew users.

Released 0.3.8 with relaxed version

[futursolo]

@cecton

I do not think this is fixed with v0.3.8.

Would it be possible to publish implicit-clone with indexmap v2 as v0.4 instead as this is a breaking change?

[cecton]

Yes I guess it creates those cases where you need to set a specific version in your lockfile. I had the same issue with serde and the likes recently on a different project. https://github.com/rust-disk-partition-management/gptman/pull/112/files

I'll bump the minor and yank that one.

[cecton]

I yanked 0.3.8. So only 0.3.6 is still available with indexmap 1.x. And I released 0.4.0 which has indexmap 2.x
