Overview for 2025-03: Substantial VM/runtime improvements in mx-sdk-rs, including a Wasmer-based VM executor prototype moved into the vm crate with a feature flag, BigInt argument extraction hooks, and memory access via the executor instance with explicit error signaling. The VM subsystem was refactored and crates reorganized, API surface modernized (TxManagedTypes -> ManagedTypeContainer; BlockchainVM -> VMConfig), and a composite executor (debug + Wasmer) introduced. Wasmer 5 integration expanded runtime capabilities (including factorial using Wasmer5), supported by targeted dependency upgrades and lockfile maintenance. Test stabilization efforts addressed path fixes and legacy test adjustments, while code cleanup and test hygiene improvements reduced debt. Overall, these changes improve reliability, flexibility, and maintainability of the VM/runtime and contract execution pipeline.
