 ## [Unreleased]
 
 ### Added
+🛠 - New non variadic `NotifyNewBlock` function. This changes the `blockservice.Interface`. The reason for this change is to avoid allocating a slice on each call when called with one block.
 
 * `boxo/bitswap/server`:
   * A new [`WithWantHaveReplaceSize(n)`](https://pkg.go.dev/github.com/ipfs/boxo/bitswap/server/#WithWantHaveReplaceSize) option can be used with `bitswap.New` to fine-tune cost-vs-performance. It sets the maximum size of a block in bytes up to which the bitswap server will replace a WantHave with a WantBlock response. Setting this to 0 disables this WantHave replacement and means that block sizes are not read when processing WantHave requests. [#672](https://github.com/ipfs/boxo/pull/672)
