• Bump rand to 0.8 and quickcheck to 1. See PR 2857.

• Update to libp2p-core v0.36.0

• Add fn set_protocol_name(&mut self, protocol_name: &'static [u8]) to MplexConfig

• Migrate to Rust edition 2021 (see PR 2339).

• Update dependencies.

• Update dependencies.

• Support stream IDs of up to 60 bit length. See PR 2094 for details.

• Update dependencies.

• Update dependencies.

• Update libp2p-core.

• Update libp2p-core.

• Change the default split_send_size from 1KiB to 8KiB. PR 1834.

• Change the default configuration to use MaxBufferBehaviour::Block and yield from waiting for the next substream or reading from a particular substream whenever the current read loop may have already filled a substream buffer, to give the current task a chance to read from the buffer(s) before the MaxBufferBehaviour takes effect. This is primarily relevant for MaxBufferBehaviour::ResetStream. PR 1825.

• Tweak the naming in the MplexConfig API for better consistency with libp2p-yamux. PR 1822.

• Update dependencies.

• Be lenient with duplicate Close frames received. Version 0.23.0 started treating duplicate Close frames for a substream as a protocol violation. As some libp2p implementations seem to occasionally send such frames and it is a harmless redundancy, this releases reverts back to the pre-0.23 behaviour of ignoring duplicate Close frames.

• More granular execution of pending flushes, better logging and avoiding unnecessary hashing. PR 1785.

• Split receive buffers per substream. PR 1784.

• Address a potential stall when reading from substreams.

• Send a Reset or Close to the remote when a substream is dropped, as appropriate for the current state of the substream, removing that substream from the tracked open substreams, to avoid artificially running into substream limits.

• Change the semantics of the max_substreams configuration. Now, outbound substream attempts beyond the configured limit are delayed, with a task wakeup once an existing substream closes, i.e. the limit results in back-pressure for new outbound substreams. New inbound substreams beyond the limit are immediately answered with a Reset. If too many (by some internal threshold) pending frames accumulate, e.g. as a result of an aggressive number of inbound substreams being opened beyond the configured limit, the connection is closed ("DoS protection").

• Update dependencies.

• Bump libp2p-core dependency.

• Bump libp2p-core dependency.

• Update libp2p-core, i.e. StreamMuxer::poll_inbound has been renamed to poll_event and returns a StreamMuxerEvent.

• Deprecated method Multiplex::is_remote_acknowledged has been removed as part of PR 1616.

• Updated dependencies.
