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});
