We are excited to announce aleph-vm in version 0.4.0.

This update brings a series of improvements and bug fixes that enhance the stability, performance, and usability of Aleph.im's virtual machine infrastructure. With this version, we aim at deploying the features introduced at the beginning of the year to the entire network.

As usual, node operators are expected to upgrade to the new release within a 2 weeks windows from the release.

Improvements and New Features

  • Improved Error Handling and Debugging: Refactoring and enhancements have been made to improve the traceability of exceptions and errors, making it easier for developers to debug issues.
  • Interface and Network Handling Enhancements: The handling of busy network interfaces and the management of network errors have been improved, including more informative logging and adjustments to prevent instance creation failures.
  • Support for QEMU Instances: aleph-vm now allows the running of QEMU instances, expanding the versatility of the virtual machine environment.
  • Runtime and Dependency Updates: Updated runtime dependencies to include newer versions of aleph-sdk-python and fastapi, among others, ensuring better performance and security.
  • Cors Support: Implemented CORS support on both supervisor and diagnostic VM endpoints, enhancing integration capabilities with different frontends.
  • Configuration Improvements: Introduced default hypervisor options and refined the configuration of MyPy for better type checking and code quality.
  • Persistent VM Management: Enhancements to the detection and management of persistent VMs improve stability and reduce potential for errors after orchestrator reboots.

Notable changes

  • Fixed a series of bugs related to VM execution stopping, interface management, and asynchronous operations that could lead to crashes or unexpected behavior.
  • Resolved issues with network interface manipulation, making error conditions more visible and manageable.
  • Adjusted the handling of missing or busy interfaces, reducing the potential for errors during VM setup.
  • Addressed various code quality issues, including outdated dependencies, incorrect type annotations, and issues identified through static analysis.
  • Enhanced the system's resilience to network and execution errors, including better handling of timeouts and busy resources.
  • Implemented several fixes and updates aimed at improving the testing environment, from integration with CodeCov to adjustments in CI workflows to ensure tests are more reliable and comprehensive.

This release consolidates several weeks of dedicated work to enhance aleph-vm's robustness, ease of use, and feature set. We appreciate the community's feedback and contributions, which have been invaluable in making these improvements possible.
