 This document outlines major changes between releases.
 
+## 0.106.1 "Implication" (3 Jun 2024)
+
+An urgent release that fixes mainnet state difference at block 5462944 which halts
+blocks processing starting from the height 5468658. This release requires full node
+DB resynchronization for mainnet nodes. T5 testnet DB state is not affected by this
+bug (at least up to the current 4087361 height). Thus, DB resynchronisation may be
+skipped for testnet nodes. No configuration changes implied.
+
+Bugs fixed:
+ * mainnet state difference at block 5462944 caused by runtime notification
+   permissions check against the updated contract state instead of executing state
+   (#3472)
+ * unused neofs-contract dependency in the node modules (#3458)
+
+## 0.106.0 "Zephyranthes" (21 May 2024)
+
+We're rolling out a large set of updates including all of Neo 3.7.4 protocol changes:
+native contracts update functionality and extended native contract APIs united under
+the upcoming Cockatrice hardfork. For smart contract developers an ability to
+generate smart contract bindings with dynamic hash is supported as well as a number
+of useful extensions for `unwrap` package, compatible NNS smart contract RPC binding
+and a lot of other handy enhancements. This release also includes a couple of severe
+regression bug fixes affecting the node state. As a bonus of fixing a wide range of
+failing tests, we've refactored the node services start and shutdown procedures to
+make it more stable. This version drops support for Go 1.19 and requires 1.20+ to
+build (with Go 1.22 supported).
+
+Notice that this release requires full node resynchronization for both mainnet
+and testnet nodes. Please pay a special attention to the Cockatrice hardfork schedule
+and check your configurations. It should be configured for 3967000 of T5 testnet and
+5450000 of mainnet. To ensure compatibility your node must be configured
+appropriately.
+

+
+## 0.105.1 "Enumeration" (12 Jan 2024)
+
+This is another v3.6.2-compatible release that fixes mainnet state difference at
+block 4688591. It is confirmed to have the same state up to 4723K height (which
+is current), but to get proper mainnet state you need to resynchronize your node
+from the genesis. T5 testnet state is not affected (at least up to the current
+3323K height), thus DB resynchronisation may be skipped for testnet nodes.
+
+Improvements:
+ * better network services logging (#3287, #3290)
+
+Bugs fixed:
+ * state difference at block 4688591 of N3 mainnet caused by difference at
+   characters escaping during manifest's `Extra` field JSON serialisation (#3286)
+
+## 0.105.0 "Designation" (29 Dec 2023)
+
+We're rolling out an update for NeoGo nodes that contains a number of user-facing
+API improvements for RPC web-socket notification subsystem, CLI utility, wallet
+related packages and not only. Try out our new `--await` CLI option for those
+commands that relay transactions to the network to automatically wait for the
+on-chain transaction execution result. Subscribe for new block headers with
+extended RPC notification subsystem interface. Use contract-based accounts
+provided by `wallet` package and `neotest` framework to sign transactions. These
+and a set of other improvements are available to our users while this release is
+staying compatible with 3.6.2 version of C# node.
+
+This version also delivers a bug fix for consensus node panic caused by improper
+native NeoToken cache initialisation. Moreover, there's a set of RPC server side
+improvements, thus, we recommend to upgrade both consensus and RPC nodes to
+provide more stable consensus node functioning and extended user APIs functionality.
+No database resynchronisation is needed.
+
+New features:
+ * block headers RPC web-socket subscription (#3252)
+ * --await option to synchronize on transaction execution for CLI commands (#3265)
+ * partial session-based RPC iterator unwrapping (#3274)
+ * contract-based transaction signers in neotest framework (#3233)
+ * AMD64 release binaries for macOS (#3251)
+ * complex contract signature schemes in wallet.Account (#3256)
+
+Behavior changes:
+ * basic RPC subscription filter validity checks are implemented on both RPC
+   client and RPC server sides (#3258)
+ * filter of notary request event RPC subscription is extended with `type` field
+   (#3236)
+ * if available, use block headers RPC web-socket subscription for transaction
+   awaiting via `waiter` package API (#3283)
+
+Improvements:
+ * add smart contract storage limits to interop utilities (#3232)
+ * extend ZKP examples documentation with additional links to PoT ceremony
+   response files (#3234)
+ * support Go types in VM emitter API (#3237)
+ * documentation update (#3239, #3242, #3246)
+ * BoltDB (go.etcd.io/bbolt) dependency upgrade (#3250)
+ * CLI code refactoring (#2682)
+ * extend wallet package to work with byte slice based wallets (#3255)
+ * export RPC client side transaction awaiting functionality via `waiter` package
+   (#3265, #3283)
+
+Bugs fixed:
+ * remove stale `updatehistory` section of `getnativecontracts` RPC response (#3240)
+ * immediately check RPC client initialisation on access to blocks RPC subscription
+   API (#3257, #3261)
+ * fix CN panic caused by unexpected call to native NeoToken cache (#3253)
+ * make "automatically generated" warning of all automatically generated files
+   follow the standard (#3280)
+
+## 0.104.0 "Globalization" (27 Nov 2023)
+
+We're updating NeoGo to push out a number of useful updates and protocol
+extensions as well as make it compatible with 3.6.2 version of C# node. The most
+invasive behaviour changes are VM-level protocol constraints imposed on the size
+of serialized stackitems and `NativeActivation` node setting removal. This version
+also delivers a set of smaller useful changes in the interoperability layer and
+native contract functionality including System.Runtime.CurrentSigners interop,
+`strLen` StdLib method and PolicyContract-based transaction attributes pricing
+as far as a user-facing `canceltx` CLI command and community-requested
+`--relative-path` CLI option.
+
+Node operators must resynchronize their nodes to get fully compatible state
+(which is confirmed to be compatible with 3.6.2 for current mainnet up to
+block 4483627 and T5 testnet up to block 3078762). Please, ensure your node
+configuration doesn't contain `NativeActivations` protocol configuration section
+as this logic is hidden under Hardforks starting from the current release.
+
+New features:
+* System.Runtime.CurrentSigners interop allowing to get signers of the currently
+  loaded transaction (#3058)
+* `strLen` method to native StdLib contract (#3208)
+* transaction attributes pricing regulation via native PolicyContract (#3155)
+* `canceltx` CLI command as an alternative to unsupported `canceltransaction` RPC
+  request (#3223, #3214)
+
+Behaviour changes:
+* reduce maximum allowed stackitem.Item size (#3185)
+* restrict maximum allowed NEF file size and prohibit large contracts deployment (#3186)
+* bind `NativeActivations` node setting to the `Hardforks` setting (#3212)
+* introduce serialization limit to stackitem.Item and fail large contracts deploy
+  wrt this setting (#3218)
+* add customizable `MaxRequestBodyBytes` and `MaxRequestHeaderBytes` RPC server
+  configuration setting (#3221)
+
+Improvements:
+* provide more detailed error on attempt to read non-existent service wallet
+  provided via node configuration file (#3210)
+* optimize emit of imported code for autogenerated RPC bindings (#3215)
+* documentation update (#3203, #3222)
+* add `--relative-path` CLI flag allowing to override configuration-specific relative
+  paths (#3206)
+* update code owners (#3216, @fyrchik will live in our hearts forever)
+
+Bugs fixed:
+* unify messages of RPC errors according to the RPC errors NEP (#3199)
+* limit maximum allowed number ad depth of transaction signers and witnesses per
+  RPC request that accept transaction (#3207, #3221)
+* forbid unknown fields usage in the node configuration file (#3209)
+* enable hardfork-dependant code starting exactly from the block height specified
+  in the node configuration (#3211)
+* require Notary native deposit to be valid for at least one subsequent block after
+  deposit transaction acceptance (#3211)
+* deduplicate unnamed event types for autogenerated RPC bindings and make the
+  binding generation order strictly defined and stable (#3215, #3220)
+* do not panic on trying to compile an import cycle (#3215)
+* state difference at block 3002333 of T5 testnet caused by difference at characters
+  escaping during manifest's `Extra` field JSON serialisation (#3225)
+* properly start node services that depend on native RoleManagement contract data
+  with genesis `Roles` protocol configuration setting specified (#3229)
+
+## 0.103.1 "Verification" (09 Nov 2023)
+
+An urgent 3.6.0-compatible version that contains a hotfix for the bug that
+prevents node from starting from the existing database every new dBFT epoch.
+Also, the release includes a bugfix that fails any non-zero NEO and GAS
+roundtrips from accounts with zero balance.
+
+Although the DB format and storage states were not affected by this release,
+the node resynchronization is still recommended for those who want to keep
+correct application logs. Resynchronization can be skipped if you're ok with
+wrong application logs for some transactions (e.g. CN doesn't care, and RPC node
+cares a lot).
+
+Bugs fixed:
+* properly initialize cache of native NeoToken contract every new dBFT epoch (#3187)
+* forbid non-zero NEO and GAS roundtrips from accounts with zero balance (#3191)
+
+## 0.103.0 "Backwardation" (20 Oct 2023)
+
+A minor 3.6.0-compatible version of NeoGo with new salty ZKP-related
+functionality, a large batch of deprecated APIs removal and an experimental
+genesis block extension. Build Groth-16 circuits, generate proofs and deploy
+verification contracts easily with the new end-to-end ZKP example and `zkpbinding`
+NeoGo API. Setup node roles via the node configuration starting from the genesis
+block without any painful multisignature transaction forming and invoke any
+custom script in the genesis-level transaction with the new `Genesis` protocol
+configuration extension. And don't forget to move from deprecated RPC client
+APIs, as a lot of them have been removed.
+
+New node configuration format is finally adapted and the deprecated configuration
+sections are permanently removed according to the schedule. Pay attention to the
+`SecondsPerBlock` protocol configuration section that was replaced by
+`TimePerBlock`, a set of node and services address- and port- related configuration
+section that were replaced by the new `Addresses` format, direct `UnlockWallet`
+consensus configuration that was replaced by a separate `Consensus` section and
+a set of node-specific protocol configurations that were moved under a separate
+`P2P` section.
+
+This release fixes a set of bugs including a vulnerability introduced by changes
+in the transaction conflicts storage scheme implemented in #3061 (a part of
+0.102.0 release). With the patch presented, it's impossible to uncontrollably
+pollute the storage with malicious conflicting records. 
+
+This version is fully compatible with C# node 3.6.0. However, it requires
+complete resynchronization on upgrade due to the database storage scheme changes.
+
+New features:
+* API for Groth-16 verification contracts autogeneration and end-to-end example for
+  proving and verifying statements on NeoGo (#3043, #3146)
+* introduce genesis protocol extensions: default node roles designation and genesis
+  transactions (#3168)
+
+Behaviour changes:
+* a lot of deprecated functionality is dropped: RPC client old APIs, shared
+  Notifications channel of WebSocket client, SecondsPerBlock protocol
+  configuration, old way of services and node address and port configuration, old
+  P2P related application settings configuration, direct UnlockWallet consensus
+  configuration, direct node-specific protocol configuration (#3150)
+* database scheme is changed by new way of storing the transaction conflicting
+  records (#3138) 
+
+Improvements:
+* NeoFS SDK dependency upgrade (#3129)
+* gnark and gnark-crypto dependencies upgrade (#3145, #3162, #3163)
+* introduce timeout restriction for BoltDB opening (#3148)
+* bump code coverage uploading action version (#3153)
+* Go 1.21 support, bump minimum required Go version up to Go 1.19 (#3157)
+* upgrade golang.org/x/net version (#3158)
+* add protocol hardforks configuration to the `getversion` RPC response (#3160)
+* format autogenerated smart contract bindings with accordance to standard `go fmt` rules (#3164)
+* add "DO NOT EDIT" warning to the autogenerated smart contract bindings (#3167)
+
+Bugs fixed:
+* avoid race between `getnextblockvalidators` RPC call handler and blockchain's
+  block handler routine, significantly refactor native validators caching scheme
+  (#3110)
+* do not panic on failed NeoFS oracle requests (#3129)
+* enable Notary subsystem in NeoFS mainnet configuration (#3136)
+* reorganize storage scheme for transaction conflicting records to avoid possible attack (#3138)
+* properly deserialize wildcard trusts field of smart contract manifest (#3140)
+* use more strict GAS limit for transaction network fee calculation via RPC call (#3141)
+* avoid WebSocket client request blocking (#3142)
+* properly emit big uint64 constants during smart contract compilation (#3147)
+* avoid race access to the node version by tests (#3149)
+* make FindStorage* RPC client APIs to be always compatible with NeoC# RPC server (#3166)
+
+## 0.102.0 "Aberration" (06 Sep 2023)
+
+Long-awaited feature-packed 3.6.0-compatible version of NeoGo with all the
+appropriate protocol updates and a set of tasty improvements and bug
+fixes. Groth16 ZKP proof checks are there for contract developers as well as
+new opcodes. A huge number of improvements went into the RPC server and
+client, new RPCs, improved contract binding generator and standardized
+extended error codes make developing dApps much easier.
+
+Users of smart contract utilities and RPC-related Prometheus metrics are
+advised to take a look at the deprecated APIs removal schedule
+(ROADMAP.md). This version was delayed for quite some time (waiting for 3.6),
+so the next minor release (0.103.0) will remove a substantial amount of
+compatibility code. It's expected to be released in November with 3.6 protocol
+compatibility (3.7 cycle is likely to require more time).
+
+This is also the first version that drops support for Go 1.17 and requires
+1.18+ to build (with Go 1.20 supported). Using generics in smart contracts is
+not supported yet, but some elements of this support can be implemented in
+future versions.
+
+Mainnet and testnet node operators, please pay attention to the Basilisk
+hardfork schedule and check your configurations. It will happen at block
+2680000 for T5 testnet and 4120000 for mainnet. To ensure compatibility your
+node must be configured appropriately. This version requires DB
+resynchronization, so schedule your updates accordingly.
+
+New features:
+ * ZKP proof checking support via CryptoLib native contract (operations with
+   BLS12-381 curve points) (#2940, #3042)
+ * System.Storage.Find interop now support "Backwards" flag to iterate in the
+   opposite direction (#2952)
+ * `util ops` CLI utility that pretty-prints VM script (#2965)

+ * `CloseNotificationChannelIfFull` WSClient option allowing the client to
+   close notification channel on overflow (#2988)
+ * autogenerated RPC bindings for contract events and conversion code from
+   stackitem.Item to structure (#3008, #3035, #3036, #3087)
+ * event type inference from contract code (#3008)
+ * dynamic contract hashes support for RPC bindings (#3012)

+ * a number of deprecated RPC-related Prometheus counters are permanently
+   removed (#2941)
+ * NEP-2 account label will be asked on account import via CLI (#2889)
+ * hashes and states of native contracts are now accessible via native
+   ContractManagement API (#2991)
+ * `serv_node_version` gauge Prometheus metric is marked as deprecated and
+   replaced by `neogo_version` and `server_id` (#3009)
+ * strict contract script check is back with Basilisk hardfork, it was
+   previously removed in 0.101.3 for 3.5 protocol compatibility (#3056)
+ * JSON number deserialization (via StdLib.jsonDeserialize) changes with
+   Basilisk hardfork allowing for more precision and handling more corner
+   cases (#3080)
+ * notification type errors are treated as fatal after Basilisk hardfork,
+   before it they're just logged (#3086)
+ * NULL and non-UTF8 items are not allowed for String event types (#3086)
+ * `Conflicts` and `NotValidBefore` transaction attributes are no longer NeoGo
+   extensions, they can be used on regular networks (#2962)
+
+Improvements:
+ * documentation and example improvements (#2945, #2972, #2979, #3020, #3084,
+   #3099, #3114, #3116, #3119, #3121)

+ * lost LastGasPerVote value on NEO state deserialization for non-voting
+   accounts (#3122)
+
+## 0.101.4 "Yarborough" (01 Aug 2023)
+
+Another one 3.5.0-compatible version that is aimed to fix T5 testnet state
+difference that has happened at block 2336911 which leads to inability to process
+new blocks since 2418703. The issue is fixed by allowing JSON numbers
+unmarshalling from scientific notation to Integer stackitem. Maximum parsing
+precision for such numbers is currently restricted by 53 bits. This is a
+temporary C#-compatible solution that is likely to change in the future versions
+when an appropriate C# node bug is fixed (neo-project/neo#2879).
+
+A set of minor bug fixes is included as well to flush some of the long-awaited
+changes that were blocked by the 0.102.0 release delay (caused by v3.6.0 C# node
+release delay). In particular, invalid headers returned by an RPC server for
+error responses, invalid format of incremental dumps created by CLI and deadlock
+on unhealthy RPC server shutdown. Long-awaited `--config-file` CLI option to
+start the node providing a single configuration file is added.
+
+T5 testnet chain requires a complete resynchronization for this version. Mainnet
+chain resynchronization is recommended, but not required.
+
+New features:
+ * `--config-file` CLI option allowing to start the node with a single configuration file (#3014)
+
+Improvements:
+ * blockchain Notary and Oracle services documentation improvement (#2972)
+ * BoltDB (`go.etcd.io/bbolt`) dependency upgrade that fixes a number of Windows-related issues (#3034)
+
+Bugs fixed:
+ * panic on node start with invalid configuration (#2968)
+ * deadlock on unhealthy RPC server shutdown (#2966)
+ * improper WSClient notification channels managing after disconnection (#2980)
+ * missing Prometheus metric initialisation on node start (#2992)
+ * invalid initialisation of native contracts cache (#2994)
+ * incorrect way of incremental DB dumps creation (#3047)
+ * Notary contract is allowed to be a sender of main Notary request transaction (#3065)
+ * discrepancy in signer's witness scope parsing on the RPC server side (#3060)
+ * Invoker calling API isn't allowed to accept nil parameter (#3067)
+ * contract RPC Client unwrapper helper can't handle missing contract case (#3072)
+ * JSON numbers can't be unmarshalled to stackitem from scientific notation (#3073)
+ * invalid content-type header returned by RPC server on error responses (#3075)
+
+## 0.101.3 "Yuckiness" (08 Jul 2023)
+
+Yet another 3.5.0-compatible emergency version that removes scrupulous
+instructions check of smart contract's script on contract deployment or update.
+Presence of this check leads to the known T5 testnet state incompatibility
+(since 1670095) which causes inability to process new blocks (since 2272533).
+It should be noted that the corresponding check was accidentally removed from
+the reference C# node implementation way back in neo-project/neo#2266 and added
+again in neo-project/neo#2849 which is planned to be a part of the upcoming
+3.6.0 C# node release. Thus, changes made in the presented 0.101.3 release will
+be reverted afterwards and strict contract script check will be present in the
+next 3.6.0-compatible version of NeoGo node.
+
+T5 testnet chain requires a complete resynchronization for this version. Mainnet
+chain resynchronization is recommended.
+
+Bugs fixed:
+
+ * extra strict contract script check on contract deployment or update is
+   removed (#3052)
+
+## 0.101.2 "Excavation" (29 Jun 2023)
+
+One more (and unexpected one!) 3.5.0-compatible version that fixes a VM bug
+leading to mainnet state incompatibility (since 3672783) which in turn leads
+to inability to process new blocks (since 3682290).
+
+Mainnet chain needs to be resynchronized for this version.
+
+Improvements:
+ * documentation updates (#3029, #2990, #2981)
+
+Bugs fixed:
+ * incorrect handling of empty Any-type parameter for RPC invocations (#2959)
+ * incorrect state rollbacks in case of exception during cross-contract call
+   when the call is made from non-TRYing context (#3046)

 # Deprecated functionality
@@ -26,100 +25,47 @@ APIs/commands/configurations will be removed and here is a list of scheduled
 breaking changes. Consider changing your code/scripts/configurations if you're
 using anything mentioned here.
 
-## Old RPC client APIs
-
-A huge set of RPC client APIs was deprecated in versions 0.99.2 and 0.99.3
-(August-September 2022), including very frequently used ones like
-SignAndPushInvocationTx, AddNetworkFee, TransferNEP17. A new set of
-invoker/actor/unwrap/nep17/etc packages was introduced decoupling these
-functions from RPC client and simplifying typical backend code. Please refer
-to rpcclient package documentation for specific replacements for each of these
-APIs and convert your code to using them.
-
-While a lot of the code is already converted to new APIs, old ones still can
-be used in some code not known to us. Therefore we will remove old APIs not
-earlier than May 2023, with 0.103.0 release.
-
-## WSClient Notifications channel and SubscribeFor* APIs
-
-Version 0.99.5 of NeoGo introduces a new set of subscription APIs that gives
-more control to the WSClient user that can pass specific channels to be used
-for specific subscriptions now. Old APIs and generic Notifications channel are
-still available, but will be removed, so please convert your code to using new
-Receive* APIs.
-
-Removal of these APIs is scheduled for May 2023 (~0.103.0 release).
-
-## SecondsPerBlock protocol configuration
-
-With 0.100.0 version SecondsPerBlock protocol configuration setting was
-deprecated and replaced by a bit more generic and precise TimePerBlock
-(allowing for subsecond time). An informational message is printed on node
-startup to inform about this, it's very easy to deal with this configuration
-change, just replace one line.
-
-Removal of SecondsPerBlock is scheduled for May-June 2023 (~0.103.0 release).
-
-## Services/node address and port configuration
-
-Version 0.100.0 of NeoGo introduces a multiple binding addresses capability to
-the node's services (RPC server, TLS RPC configuration, Prometheus, Pprof) and
-the node itself. It allows to specify several listen addresses/ports using an
-array of "address:port" pairs in the service's `Addresses` config section and
-array of "address:port:announcedPort" tuples in the `ApplicationConfiguration`'s
-`Addresses` node config section. Deprecated `Address` and `Port` sections of
-`RPC`, `Prometheus`, `Pprof` subsections of the `ApplicationConfiguration`
-as far as the one of RPC server's `TLSConfig` are still available, but will be
-removed, so please convert your node configuration file to use new `P2P`-level
-`Addresses` section for the node services. Deprecated `Address`, `NodePort` and
-`AnnouncedPort` sections of `ApplicationConfiguration` will also be removed
-eventually, so please update your node configuration file to use `Addresses`
-section for the P2P addresses configuration.
-
-Removal of these config sections is scheduled for May-June 2023 (~0.103.0 release).
-
-## P2P application settings configuration
-
-Version 0.100.0 of NeoGo marks the following P2P application settings as
-deprecated: `AttemptConnPeers`, `BroadcastFactor`, `DialTimeout`,
-`ExtensiblePoolSize`, `MaxPeers`, `MinPeers`, `PingInterval`, `PingTimeout`,
-`ProtoTickInterval`. These settings are moved to a separate `P2P` section of
-`ApplicationConfiguration`. The `DialTimeout`, `PingInterval`, `PingTimeout`,
-`ProtoTickInterval` settings are converted to more precise `Duration` format
-(allowing for subsecond time). Please, update your node configuration (all you
-need is to move specified settings under the `P2P` section and convert
-time-related settings to `Duration` format).
-
-Removal of deprecated P2P related application settings is scheduled for May-June
-2023 (~0.103.0 release).
-
-## Direct UnlockWallet consensus configuration
-
-Top-level UnlockWallet section in ApplicationConfiguration was used as an
-implicit consensus service configuration, now this setting (with Enabled flag)
-is moved into a section of its own (Consensus). Old configurations are still
-supported, but this support will eventually be removed.
-
-Removal of this compatibility code is scheduled for May-June 2023 (~0.103.0
-release).
-
-## Node-specific configuration moved from Protocol to Application
-
-GarbageCollectionPeriod, KeepOnlyLatestState, RemoveUntraceableBlocks,
-SaveStorageBatch and VerifyBlocks settings were moved from
-ProtocolConfiguration to ApplicationConfiguration in version 0.100.0. Old
-configurations are still supported, except for VerifyBlocks which is replaced
-by SkipBlockVerification with inverted meaning (and hence an inverted default)
-for security reasons.
-
-Removal of these options from ProtocolConfiguration is scheduled for May-June
-2023 (~0.103.0 release).
-
 ## GetPeers RPC server response type changes and RPC client support
 
 GetPeers RPC command returns a list of Peers where the port type has changed from 
 string to uint16 to match C#. The RPC client currently supports unmarshalling both
 formats. 
 
-Removal of Peer unmarshalling with string based ports is scheduled for ~September 2023
-(~0.105.0 release).
+Removal of Peer unmarshalling with string based ports is scheduled for Jun-Jul 2024
+(~0.107.0 release).
+
+## `NEOBalance` from stack item
+ 
+We check struct items count before convert LastGasPerVote to let RPC client be compatible with
+old versions.
+
+Removal of this compatiblility code is scheduled for Jun-Jul 2024.
+
+## `serv_node_version` Prometheus gauge metric
+
+This metric is replaced by the new `neogo_version` and `server_id` Prometheus gauge
+metrics with proper version formatting. `neogo_version` contains NeoGo version
+hidden under `version` label and `server_id` contains network server ID hidden
+under `server_id` label.
+
+Removal of `serv_node_version` is scheduled for Jun-Jul 2024 (~0.107.0 release).
+
+## RPC error codes returned by old versions and C#-nodes 
+
+NeoGo retains certain deprecated error codes: `neorpc.ErrCompatGeneric`, 
+`neorpc.ErrCompatNoOpenedWallet`. They returned by nodes not compliant with the 
+neo-project/proposals#156 (NeoGo pre-0.102.0 and all known C# versions).
+
+Removal of the deprecated RPC error codes is planned for Jun-Jul 2024 (~0.107.0
+release).
+
+## Block based web-socket waiter transaction awaiting
+
+Web-socket RPC based `waiter.EventWaiter` uses `header_of_added_block` notifications
+subscription to manage transaction awaiting. To support old NeoGo RPC servers
+(older than 0.105.0) that do not have block headers subscription ability,
+event-based waiter fallbacks to the old way of block monitoring with
+`block_added` notifications subscription.
+
+Removal of stale RPC server compatibility code from `waiter.EventWaiter` is
+scheduled for Jun-Jul 2024 (~0.107.0 release).
