+- [Bitcoin Core #29954][] extends the `getmempoolinfo` RPC by adding two relay
+  policy fields to its response object: `permitbaremultisig` (whether the node
+  relays bare multisig outputs) and `maxdatacarriersize` (the maximum aggregate
+  bytes allowed in OP_RETURN outputs for a transaction in the mempool). Other
+  policy flags, such as [`fullrbf`][topic rbf] and `minrelaytxfee`, were already
+  exposed, so these additions allow for a complete relay policy snapshot.
+
+- [Bitcoin Core #33004][] enables the `-natpmp` option by default, allowing
+  automatic port forwarding via the [Port Control Protocol (PCP)][pcp] with a
+  fallback to the [NAT Port Mapping Protocol (NAT-PMP)][natpmp] (see Newsletter
+  [#323][news323 natpmp]). A listening node behind a router that supports either
+  PCP or NAT-PMP becomes reachable without manual configuration.
+
+- [LDK #3246][] enables the creation of [BOLT12 offers][topic offers] and
+  refunds without a [blinded path][topic rv routing] by using the offer’s
+  `signing_pubkey` as the destination. The `create_offer_builder` and
+  `create_refund_builder` functions now delegate blinded path creation to
+  `MessageRouter::create_blinded_paths`, where a caller can generate a compact
+  path by passing `DefaultMessageRouter`, a full-length pubkey path with
+  `NodeIdMessageRouter`, or no path at all with `NullMessageRouter`.
+
+- [LDK #3892][] exposes the merkle tree signature of [BOLT12][topic offers]
+  invoices publicly, enabling developers to build CLI tools or other software to
+  verify the signature or recreate invoices. This PR also adds an `OfferId`
+  field to BOLT12 invoices to track the originating offer.
+
+- [LDK #3662][] implements [BLIPs #55][], also known as LSPS05, which defines
+  how clients can register for webhooks via an endpoint to receive push
+  notifications from an LSP. The API exposes additional endpoints that enable
+  clients to list all webhook registrations or remove a specific one. This can
+  be useful for clients to get notified when receiving an [async payment][topic
+  async payments].
