v2.0.0

[notgull]

Changes:

• Add support for the the portable_atomic and loom crates. (Add alternate implementations of synchronization primitives #27)
• Breaking: Add an std feature that can be disabled to use this crate on no_std platforms. (Make it so this crate can be no_std #22)
• Replace usage of cache-padded with crossbeam-utils. (Replace cache_padded with crossbeam-utils #26)

"adding an std feature" is only a breaking change because crates can opt to default-features = false, right?

Yes. With the std feature, certain traits that are normally implemented on concurrent-queue are disabled. There is a way around it (see #29), but it's probably better to just go with the breaking change.

I'm not sure if we should release a new version yet, or check if downstream crates might need some additional modifications...

All of smol's crates do not use concurrent-queue as a public dependency. smol is by and large the largest user of concurrent-queue; all of its crates have about 10 million downloads, while the next largest consumer (jackiechan) has about 50k downloads. Of the crates with more than 10k downloads:

• jackiechain and barrage are unmaintained forks of async-channel with an alternate version of Add blocking functionality to channels async-channel#47 implemented.
• sosistab imports concurrent-queue but never uses it.

None of these crates have concurrent-queue as a public dependency. Every other crate involved has less than 10k downloads.

Maybe update authors. We can't update edition due to the would-be-implied msrv bump

[notgull]

I've added myself and @taiki-e to the authors list, since the GitHub contributors tab shows that we are the main contributors to this crate.

@smol-rs/admins It looks like I don't have push permissions, so the release didn't take. Does anyone mind making the push?

[taiki-e]

Published. Thanks for working on this!

(In the future I would like to set up CI to publish the crate via tag push like my crates.)
