 ### Changed
 
-- `bitswap/client`: Do not send CANCEL to peer that block was received from, as this is redundant. [#784](https://github.com/ipfs/boxo/pull/784)
 - `gateway`: The default DNSLink resolver for `.eth` TLD changed to `https://dns.eth.limo/dns-query` [#781](https://github.com/ipfs/boxo/pull/781)
 - `gateway`: The default DNSLink resolver for `.crypto` TLD changed to `https://resolver.unstoppable.io/dns-query` [#782](https://github.com/ipfs/boxo/pull/782)
 - upgrade to `go-libp2p-kad-dht` [v0.28.2](https://github.com/libp2p/go-libp2p-kad-dht/releases/tag/v0.28.2)
