near-sdk (Rust) 2.0.1

2.0.1

Contract changes

• Updated status-message-collections to use LookupMap
• BREAKING Updated fungible-token implementation to use LookupMap. It changes storage layout.

API changes

• Introduce LookupMap and LookupSet that are faster implementations of UnorderedMap and UnorderedSet, but without support for iterators. Most read/lookup/write are done in 1 storage access instead of 2 or 3 for Unordered* implementations.
• BREAKING Default is removed from near_sdk::collections to avoid implicit state conflicts. Collections should be initialized by explicitly specifying prefix using new method.
• BREAKING TreeMap implementation was updated to use LookupMap. Previous TreeMap implementation was renamed to LegacyTreeMap and was deprecated. LegacyTreeMap should only be used if the contract was already deployed and the state has to be compatible with the previous implementation.

1.0.1

Other changes

• Remove requirements for input args types to implement serde::Serialize and for return types to implement serde::Deserialize.

Fix

• Bumped dependency version of near-vm-logic and near-runtime-fees to 2.0.0 that changed VMLogic interface.
