October 2025 monthly summary focused on delivering CI reliability, cross-platform compatibility, and runtime stability across two repositories (GEMScienceTools/oq-mbtk and gem/oq-engine). Key work included integrating the oq-engine test_pyproj branch into local installs and CI to test against newer Python features; introducing architecture-specific macOS dependencies (ARM64/x86_64) with explicit wheel URLs; and aligning Windows CI with Python 3.11 dependencies by removing legacy installation commands. In oq-engine, we modernized the environment to Python 3.12+ by updating Dockerfiles, CI, and test workflows (and removing Python 3.10); upgraded geospatial and ML runtimes (GDAL, PyProj, Fiona, Geopandas, ONNX Runtime) with updated wheels and certifi; and expanded Python 3.13 testing matrix with compatibility cleanup. These enhancements reduce setup friction, expand cross-platform support, and improve test coverage and reliability, delivering business value through faster feature delivery, easier developer onboarding, and more stable production readiness.

September 2025 monthly highlights for gem/oq-engine: Delivered Windows-ready geospatial functionality and improved deployment clarity, strengthening cross-platform readiness and business value.

July 2025 — gem/oq-engine: Implemented geospatial indexing capability by integrating the h3 Python library (v3.7.7) on macOS for ARM64 and x86_64 across Python 3.10–3.12. This work expands platform coverage, enables geospatial workflows, and positions us to deliver location-aware features. Two commits completed: 80cae871107be1f3f9e57a36f6249b223c99722a (add h3 for macos arm64) and a396bc7e26c7137132eee9bb81596e2b0efe17a6 (add h3 for macos x86_64).

June 2025: gem/oq-engine — Stabilized CI/CD by upgrading Windows runner to Windows-2025 and deprecation-proofing the workflow. Implemented Windows Runner Compatibility Update in the GitHub Actions workflow to address Windows-2019 deprecation and ensure pipelines remain aligned with current infrastructure. Result: preserved CI stability, reduced maintenance toil, and smoother future infra migrations. Commit and validation were performed in the gem/oq-engine repository.

May 2025 for gem/oq-engine focused on delivering cross‑platform packaging, dependency upgrades, and CI/CD enhancements to accelerate delivery and reliability across Linux, Windows, and macOS (x86_64 and arm64). Key features include numpy 2.0 wheels across all platforms, LLVMLite in all environments, and upgrades to Pandas 2.2.3, SciPy 1.15.3, and H5py 3.13 with platform-specific wheels. CI improvements introduced weekly tests, branch-aware workflows, and workflow_dispatch for manual retries; nightly user-mode tests and curl-based install.py retrieval were added to strengthen automation. Additional improvements cover venv naming consistency, SSH debugging hooks post-install, and several infrastructure refinements (M1 path corrections, Windows CI, Django 4.2.21 in stack). Overall, these changes reduce deployment friction, improve cross‑platform stability, and accelerate iteration cycles across the product stack.

April 2025 monthly summary for gem/oq-engine focused on delivering reproducible cluster provisioning, code quality improvements, and cross-OS support. Highlights include end-to-end automation with Vagrant and Ansible, dynamic inventory handling, OS-aware provisioning for Debian/Rocky, and maintainability enhancements to the Vagrantfile.

March 2025 monthly summary for gem/oq-engine: Delivered a production-focused Docker-based development and test environment, enhanced cluster validation, and strengthened security, CI/CD, and installation workflows. The work enables reproducible builds, safer non-root operation, and faster validation of OpenQuake changes, delivering clear business value and technical resilience.

February 2025 monthly summary focusing on delivery of CI/CD and packaging improvements across two repos, with emphasis on business value and technical achievements.

January 2025 summary for gem/oq-engine: Licensing and copyright notice updates across the repository, Windows installation documentation updated with new screenshots, DevOps build/CI stabilization with aligned Docker images and a broader Python version matrix, and enforcement of a minimum Python version (3.10) in the installer. These changes enhance legal compliance, user onboarding for Windows, build reliability, and installation safety.

December 2024 monthly summary for gem/oq-engine focusing on user-guided installation, CI/CD reliability, and alignment with master branch to reduce inconsistencies. Key activities include documentation of RAM requirements, installation script cleanup, and substantial CI/CD workflow hardening to improve branch handling and error resilience. These efforts enhanced user onboarding, reduced deployment failures, and positioned the project for smoother future releases.

November 2024 monthly summary: Focused on security hardening, timezone support, and cross-platform compatibility across gem/oq-engine and GEMScienceTools/oq-mbtk. The work delivered reduces origin-check failures, enables timezone-aware data handling across Python 3.10-3.12, and stabilizes dependencies for multi-OS deployments.

In October 2024, the gem/oq-engine CI/KI pipeline improvements focused on stabilizing cross-platform test execution, tightening environment handling, and making CI feedback more reliable and actionable. The work emphasizes business value through reduced flaky builds, faster feedback, and clearer signals to developers while maintaining strong cross-OS compatibility.
