+## 0.107.0 "Mongrelization" (03 Dec 2024)
+
+A large update that introduces a major node extension: NeoFS BlockFetcher service and
+`util upload-bin` CLI command implemented as a part of [NeoFS snapshot storage
+proposal](https://github.com/neo-project/neo/issues/3463). BlockFetcher service, as
+an alternative to P2P synchronization mechanism, allows to download blocks and sync
+chain from block dumps stored in NeoFS. Starting from this release, NeoSPCC team
+maintains chain dumps in NeoFS for N3 and NeoFS public networks. The default NeoGo
+node configuration for these networks has been changed to use NeoFS BlockFetcher as
+a synchronization mechanism prior to P2P synchronization. Other than that, this
+release includes NEP-24 standard support at both compiler and SC bindings generator
+levels. A large number of tiny user-facing enhancements is rolled out for RPC
+actor/ivoker, `neotest` and `unwrap` packages as far as for CLI utilities. Also,
+this release contains a set of NeoGo VM bug fixes inspired by differential VM fuzzing
+study conducted by our external contributor @Slava0135 and a set of tiny VM CLI
+enhancements introduced by @ixje.
+
+Some deprecated functionality has been removed according to the schedule, see more
+details in the `Behaviour changes` section. Also, for those node operators who would
+like to check out our new NeoFS BlockFetcher node extension, we'd recommend to add
+corresponding section to the node's configuration (see the default node configuration
+for N3/NeoFS networks for example).
+
+This release is fully compatible with 3.7.5 version of C# node, no DB resync is
+needed.
+
+New features:
+ * new NeoFS BlockFetcher service that allows to sync node from NeoFS chain dump
+   (#3515, #3636, #3637, #3632, #3691, #3706, #3668, #3713)
+ * new `util upload-bin` CLI command that allows to upload blocks from Neo chains to

+ * NEP-24 standard support (#3560)
+ * Echidna hardfork introduced, but not yet enabled (please, note that this is only
+   a preview that includes a part of scheduled changes and will be changed in an
+   incompatible way before the full support, hence, this hardfork may be enabled for
+   experimental purpose only) (#3554)

+Behavior changes:
+ * neotest's AddSystemFee and TestInvoke are bound to Executor state (#3551)
+ * getversion RPC response is extended with seed list and standby committee (#3540)
+ * support only two latest versions of Go instead of three (#3567)
+ * some deprecated functionality is dropped: unmarshalling code for the old
+   `getpeers` RPC response, `NEOBalance` stackitem deserializer compatibility code,
+   `serv_node_version` Prometheus gauge metric, outdated RPC error codes support,
+   block-based web-socket transaction awaiting (#3690)

+ * netmode package is extended with public NeoFS chain IDs (#3539)
+ * dBFT library upgrades (#3541, #3711)
+ * migration to Docker Compose V2 (#3547)

+   (#3551)
+ * ability to customize awaiting options for PollingBased RPC waiter (#3556)
+ * Go 1.23 support, bump minimum required Go version up to Go 1.22 (#3567)
+ * a set of dependent libraries upgrades (#3570)
+ * extend the list of supported SC parameters for RPC actor/invoker (#3583)
+ * Null stackitem result handling for autogenerated RPC bindings (#3584)
