+# Claude Guidelines for mx-sdk-rs
+
+## Auto-Generated Files — Do Not Edit
+
+Never modify files that begin with `// Code generated`. These are auto-generated by the build system and will be overwritten.
+
+This applies especially to:
+
+- **Proxy files** (`*_proxy.rs`) — generated with: `sc-meta all proxy`
+- **Wasm crate contents** (`*/wasm/src/lib.rs`, `*/wasm/Cargo.toml`) — generated by the multiversx-sc build system, with: `sc-meta all build`
+
+If a change is needed in an auto-generated file, modify the source it is generated from (e.g. the smart contract trait or `sc-config.toml`) and regenerate:

 ## Version history
 
+### [sc 0.65.1, chain 0.22.1, sdk 0.15.1] - 2026-03-25
+- `sc-meta` improvements:
+	- `sc-meta wallet new --shard <id>` flag: generates a new wallet whose address belongs to the given shard;
+	- `sc-meta all proxy`
+		- Better crate path handling;
+		- `--verbose` flag: prints each proxy file path as it is generated.
+	- `sc-meta test-gen` generates `.insert_ghost_accounts()` call in test setup (only used in internal tests).
+- SDK:
+	- Accept trailing slash in gateway URL (automatically normalized);
+	- Fixed a transaction decode issue in `sdk/core`;
+	- Test wallets provided for each shard, including a function that returns the wallet for that `ShardId`.
+- Chain core: new `ShardId` type and `ShardConfig` infrastructure:
+	- `ShardId` represents a shard identifier, with special values for metachain;
+	- `ShardConfig` encodes the shard structure of the network (number of shards, address distribution);
+	- Functionality to get the shard of an `Address`;
+	- Utility for checking whether an address is of a system SC.
+- Base framework improvements:
+	- `ManagedArgBuffer` implements `ManagedVecItem`.
+	- `Display` trait implemented by `BigInt`, `BigUint`, `NonZeroBigUint`, `Payment` and `EsdtTokenPayment`.
+
