## 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
