+## 0.100.0 "Centuplication" (08 Dec 2022)
+
+A 3.5.0-compatible version of NeoGo with all the appropriate protocol updates
+and a number of other changes. The most notable ones are configuration
+updates. New features and some long-standing inconsistencies required for some
+changes and this release brings them with it. Old configurations are still
+supported and will work the same way (except for one minor exception in
+VerifyBlocks that is only supposed to be used for tests/development), but we'd
+like to highlight that all of the old settings will be removed in ~6 months,
+so please review these updates and update your configurations. For public
+networks the best way to go is to take the new versions from the "config"
+directory and then adjust for particular scenario if needed.
+
+This release requires a complete resynchronization due to native contract
+changes, so please schedule your updates appropriately.
+
+New features:
+ * System.Runtime.LoadScript syscall (and appropriate smart contract interops)
+   allowing to load/run dynamic code (#2719)
+ * PUSHT/PUSHF VM instructions allowing for simpler/cheaper booleans (#2770)
+ * ContractManagement native contract was extended with ID->hash mappings and
+   `getContractById` and `getContractHashes` methods (#2702, #2837)
+ * LogLevel application configuration option that can be changed on SIGHUP
+   (#2831)
+ * additional type data generated by the compiler that then can be used by the
+   RPC bindings (SDK/contract wrapper) generator, this allows for complex
+   types (structures/arrays/maps) to be easily represented/handled in
+   contract-specific RPC code (#2828)
+ * multiaddress listeners for all services and P2P, this changes the old
+   Address/Port (and AnnouncedPort for P2P) configuration scheme to more
+   generic Addresses list, the old configuration is still supported, but is
+   deprecated and will be removed in future node versions (#2827, #2839)
+
+Behaviour changes:
+ * Aspidochelone fork block for NeoFS sidechain mainnet configuration is
+   rescheduled again (#2823, #2830)
+ * Blockchain's GetHeaderHash() method now accepts uint32 for parameter
+   (#2814)
+ * pre-0.97.3 and pre-0.99.0 deprecated compatibility fields and logic were
+   dropped from the result.Version (`getversion` RPC result) structure (#2786)
+ * SecondsPerBlock protocol configuration variable was replaced with
+   TimePerBlock allowing for sub-second precision, SecondsPerBlock is still
+   supported, but will eventually be removed (#2829)
+ * AttemptConnPeers, BroadcastFactor, DialTimeout, ExtensiblePoolSize,
+   MaxPeers, MinPeers, PingInterval, PingTimeout, ProtoTickInterval settings
+   were moved into the new P2P section, timing parameters now use Duration
+   type allowing for more human-friendly values in many cases, old parameters
+   are still supported, but will eventually be removed (#2827)
+ * consensus (dBFT) is configured as a separate service now that can be
+   enabled/disabled (and can work in "watch only" mode without a wallet), the
+   old direct "UnlockWallet" specification in "ApplicationConfiguration" is
+   still supported, but is deprecated and will be removed in future versions
+   (#2832)
+ * GarbageCollectionPeriod, KeepOnlyLatestState, RemoveUntraceableBlocks,
+   SaveStorageBatch and VerifyBlocks settings were moved from
+   ProtocolConfiguration to ApplicationConfiguration; old configurations are
+   still supported, except for VerifyBlocks which is replaced by
+   SkipBlockVerification with inverted meaning (and hence an inverted default)
+   for security reasons; this also affects NewBlockchain and neotest APIs
+   (#2833)
+
+Improvements:
+ * more user-friendly error and help messages in some cases (#2824, #2834)
+ * faster node startup time and smaller memory footprint for networks with
+   lots (1-2M+) of blocks (#2814)
+ * minor documentation fixes (#2834, #2838)
+
+Bugs fixed:
+ * transactions with system fee or more than MaxBlockSystemFee are no longer
+   accepted into the mempool, preventing a form a network-wide DoS (#2826)
+ * deprecated WSClient subscription methods not working correctly when filters
+   are being used (#2836)
+

-## getversion RPC reply Magic and StateRootInHeader fields
-
-"getversion" RPC reply format was extended to contain "protocol" section in
-version 0.97.3. Since then we have deprecated Magic and StateRootInHeader
-fields in the Version structure that allows to decode replies from pre-0.97.3
-servers while RPC server implementation populates both old and new fields for
-compatibility with pre-0.97.3 clients.
-
-Version 0.97.3 was released in October 2021 and can't really be used today on
-public networks, we expect at least 0.99.0+ to be used in production (0.99.2+
-for C# 3.4.0 compatibility). Therefore these old fields are scheduled to be
-removed in version 0.100.0 both client-side and server-side. If any of your
-code uses them, just use the Protocol section with the same data.
-
-## InitialGasDistribution field of getversion RPC reply
-
-An incompatibility with C# node's InitialGasDistribution representation was
-detected and fixed in version 0.99.0 of NeoGo (June 2022). Some compatibility
-code was added to handle pre-0.99.0 servers on the client side, however it was
-not possible to change pre-0.99.0 clients to work with newer servers.
-
-We expect all servers to be migrated to 0.99.0+ by now, therefore
-compatibility code will be removed in version 0.100.0.

 ## Old RPC client APIs
 
 A huge set of RPC client APIs was deprecated in versions 0.99.2 and 0.99.3
