With https://github.com/libp2p/rust-libp2p/pull/3658, these crates depend on the `0.42.1` release to access the new `ToSwarm` type. With the currently specified version, a user could theoretically run into a compile error if they pin `libp2p-swarm` to `0.42.0` in their lockfile but update to the latest patch release of one of these crates.
Pull-Request: #3711.
Doesn't change any functionality but `pop` returns an `Option` whereas `remove` will panic on out-of-bounds. I am more comfortable with `pop` and a pattern match. Also, usage of `continue` allows us to not use an `else`.

Previously, we only mutably borrowed the `last_seq_no` in the current scope but did not modify the underlying number. This is because `u64` is copy and calling `wrapping_add` consumes `self` so the compiler just copied it. We introduce a new-type instead that is not `Copy`.
Additionally, `wrapping_add` and initializing with a random u64 might actually warp the number and thus not give us sequential numbers as intended in #3551. To solve this, we initialize with the current unix timestamp in nanoseconds. This allows a node to publish 1000000 messages a second and still not reuse sequence numbers even after a restart / re-initialization of the configuration. This is also what the go implementation does.
Resolves#3714.

This tiny PR contains a proposed change for the warning related to the exceeded pending incoming connections limit. This warning can't be controlled and causes user confusion. It contains useful technical info but IMHO should be downgraded from `warn` to `debug`.
Pull-Request: #3671.
All we need from the multihash is for it to be a data structure that we pass around. We only ever use the identity "hasher" and the sha256 hasher. Those are easily implemented without depending the (fairly heavy) machinery in `multihash`.
Unfortunately, this patch by itself does not yet lighten our dependency tree because `multiaddr` activates those features unconditionally. I opened a companion PR for this: https://github.com/multiformats/rust-multiaddr/pull/77.
https://github.com/multiformats/rust-multiaddr/pull/77 is another breaking change and we are trying to delay those at the moment. However, it will (hopefully) land eventually which should then be much easier to implement.
Fixes#3276.

With an upgrade to the Rust toolchain, the version of the rustdoc JSON may change. We incorporate the rustc version into the cache key to automatically invalidate the cache in that case. Additionally, we also incorporate the version of the `cargo semver-checks` tool.

Pull-Request: #3664.
`Certificate#fingerprint()` returns `Fingerprint`, but since it's not
public, I was not able to test it in my project. I.e. before this change it was
not possible to do:
```
cert.fingerprint() == Fingerprint::raw([1u8 ...])
```

The check for fanout peer inclusion in `test_join` does not check anything since `new_peers` is always empty.
12b785e94e/protocols/gossipsub/src/behaviour/tests.rs (L611)
I assume the intention was to fill the `new_peers` with the fanout peers. In this MR I do just that.
Pull-Request: #3628.
Currently, banning peers is a first-class feature of `Swarm`. With the new connection management capabilities of `NetworkBehaviour`, we can now implement allow and block lists as a separate module.
We introduce a new crate `libp2p-allow-block-list` and deprecate `Swarm::ban_peer_id` in favor of that.
Related #2824.
Pull-Request: #3590.
In earlier iterations of the design for generic connection management, we removed the `ConnectionId::new` constructor because it would have allowed users to create `ConnectionId`s that are already taken, thus breaking invariants that `NetworkBehaviour`s rely on. Later, we incorporated the creation of `ConnectionId` in `DialOpts` which mitigates this risk altogether.
Thus, it is reasonably safe to introduce a public, non-deprecated constructor for `ConnectionId` that can be used for tests.

Pull-Request: #3652.
We currently expose `libp2p-quic` and `libp2p-webrtc` as submodules from the `libp2p` crate despite those only being "alpha" status. This causes problems because we need to pin those dependencies due to `cargo` automatically upgrading alphas (which are allowed to incur breaking changes as per semver spec). Additionally, exposing these modules practically hides the "alpha" state of those modules, rendering it kind of obsolete.
The "alpha" state is still true for those modules, thus to properly communicate this to users, we deprecate the modules and require users to spell out the dependency and the alpha version in their manifest.
