near-sdk-v5.1.0

Hightlights

Reduce your boilderpate and enable ABI support out of the box with the new #[near] macro-attribute.

BEFORE (still valid, not breaking changes or depreaction in this release):	AFTER
use near_sdk::serde::{Deserialize, Serialize} use near_sdk::borsh::{BorshDeserialize, BorshSerialize}; use near_sdk::schemars::JsonSchema; #[derive(Deserialize, Serialize, JsonSchema, BorshDeserlialize, BorshSerialize)] #[serde(crate = "near_sdk::serde")] #[schemars(crate = "near_sdk::schemars")] #[borsh(crate = "near_sdk::borsh")] struct ...	use near_sdk::near; #[near(serializers = [borsh, json])] struct ...
use near_sdk::{near_bindgen, env}; #[near_bindgen] #[derive(Default, BorshDeserialize, BorshSerialize)] #[borsh(crate = "near_sdk::borsh")] pub struct StatusMessage { records: HashMap<AccountId, String>, } #[near] impl StatusMessage { ... }	use near_sdk::{near, env}; #[near(contract_state)] #[derive(Default)] pub struct StatusMessage { records: HashMap<AccountId, String>, } #[near] impl StatusMessage { ... }

If you want to have an example, look no further, DevHub Contract is already migrated
