+#### Removal of `/quic` (Draft 29) support
+
+Kubo no longer supports QUIC Draft 29. This means that older nodes aren't able to connect
+to newer nodes using QUIC Draft 29. However, they are still able to connect through any other
+transport that both nodes talk (such as QUIC RFC 9000, or TCP). QUIC Draft 29 was a preliminary implementation of QUIC before
+the official RFC 9000 was published, and it has now been dropped by [`go-libp2p`](https://github.com/libp2p/go-libp2p/releases/tag/v0.30.0)
+and therefore Kubo.
+
+In [Kubo 0.18](https://github.com/ipfs/kubo/releases/tag/v0.18.0), we shipped a migration
+to have listeners for both `/quic` (Draft 29) and `/quic-v1` (RFC 9000). Similarly, in this
+version we are shipping a migration to remove the current `/quic` addresses, maintaining
+the `/quic-v1` addresses only. For more background information, check [issue #9496](https://github.com/ipfs/kubo/issues/9496).
