Compatibility Notes

Internal Changes

Other

v1.11.0

Enhanced Dependency System

The latest update dramatically simplifies the development of Leo projects with enhanced support for external calls to both on-chain and local programs.

• Breaking Change: Now use import foo.aleo instead of import foo.leo, and attach the dependency using the CLI.
• New .aleo/registry structure in the ~/.aleo file system to store .aleo files from the Aleo network.
• Ability to automatically retrieve network dependencies and build complicated nested dependency structures.

// Pull credits.aleo as a dependency
leo add -n credits

// Add a local dependency named foo.aleo at path ../foo
leo add -l ../foo foo

// Attach dependencies in the Leo file
import credits.aleo
import foo.aleo

Reading External Mappings

Leo allows users to read external mappings.

let val:u32 = Mapping::get(token.aleo/account, 0u32);
let val_2:u32 = Mapping::get_or_use(token.aleo/account, 0u32, 0u32);

Relaxed Shadowing

Local mapping, struct, record and function names can now overlap with external objects.

let bar: hello.aleo/foo = bye.aleo/foo(foo {a: 1u32, b: 1u32});

v1.10.0

This release contains:

• SHA3 hash functions.
• Keccak hash functions.
• Constant declarations.
• self.signer and self.caller.
• compatibility updates with snarkVM 0.16.1.

SHA3 and Keccak

Leo supports 235, 384, and 512 bit variants for SHA3 and Keccak.

let a: address = SHA3_256::hash_to_address(input);
let b: u8 = SHA3_384::hash_to_u8(input);
let c: field = SHA3_512::hash_to_field(input);
let d: group = Keccak256::hash_to_group(input);
let e: i8 = Keccak384::hash_to_i8(input);
let d: u16 = Keccak512::hash_to_u16(input);

Constant Declarations

Leo allows users to declare global and local constants.

const START: u8 = 0u8;

self.signer and self.caller

Leo supports:

• self.signer, which is the user that originated the program call.
• self.caller, which is the user or program that called the current function.

Suppose that a user calls program A which calls program B.
In program A:

• self.signer is user.
• self.caller is user.

In program B:

• self.signer is user.
• self.caller is A.

Note what was previously self.caller is now self.signer.
