May 2025 monthly summary for demergent-labs/azle: Delivered foundational inter-canister batching and futures core with robust error propagation, enabling safer multi-canister workflows. Implemented end-of-method spawning to resolve already-borrowed errors, completed batching flow, and refined error handling. Coordinated macrotask/microtask draining to ensure correct inter-canister drain sequencing, reducing race conditions during cross-canister interactions. Added inter-canister futures tests to validate batching behavior and futures state. Introduced experimental drain_microtasks feature and added missing experimental mode method to enable upcoming workflow optimizations. Performed extensive code cleanup and documentation improvements (renaming, comments, Rust docs, and templates), and strengthened the test suite with enhanced event loop coverage. Updated dependencies and tooling alignment (ic-cdk updates, canister IDs for new subnet, backtrace toggling). These changes reduce failure modes, improve reliability and maintainability, and accelerate delivery of cross-canister features with measurable business value.
