December 2025 — IETS3/iets3.opensource monthly summary Key features delivered: - Build system and dependency management enhancements: consolidated build and dependency improvements across the project, including version alignment for 2024.1, test and runtime dependencies, dependency resolution refinements, MPS 2025.1 compatibility, build script cleanups, branch adaptation, new language runner integration, Gradle wrapper cleanup, and prerelease versioning. Representative commits include: adjust versions to reflect the state of 20241 branch; adjust build script to reflect the state of 20241 branch; regenerate build-allScripts.xml; adapt build for master; prerelease for mpsQa and mbeddr. - MPS language tooling improvements: updates to MPS language models and integration, enhancing behavior, documentation structure, and JavaDoc/solver functionality (commit: run migrations with MPS-253.28294.10098). - Interpreter and runtime module modernization: migration to newer dependencies with new interpreter and runtime modules and updated language versions to modernize execution capabilities (commit: migrate remigrate). - SBOM generation and compliance improvements: added missing dependencies to the SBOM generation process to improve dependency management and compliance (commit: add missing dependencies in sbom). Major bugs fixed: - Behavior model migration regression fix: revert migration-related changes that affected the handling of the behavior model, JavaDoc structures, and solver tasks to restore correct behavior (commit: Revert "ran migrations with MPS-253.28294.414"). Overall impact and accomplishments: - Strengthened build reliability and consistency across branches, enabling smoother releases and prerelease workflows. - Improved security/compliance posture through enhanced SBOM generation. - Enabled modernized execution with updated interpreter/runtime modules and language tooling, supporting future migrations to MPS 2025.x. - Reduced risk from migration-driven regressions by promptly reverting regression-causing changes and restoring stable behavior models and tooling integration. Technologies/skills demonstrated: - Build tooling and dependency management (Gradle, script cleanups, wrapper maintenance) - MPS language tooling and migrations - Interpreter/runtime modernization and language version upgrades - SBOM generation and compliance practices - Regression diagnosis and targeted fixes in migration-related code

For 2025-11, delivered foundational editor and infrastructure improvements in IETS3/iets3.opensource to boost reliability, data access, and maintainability. The work emphasizes business value by stabilizing core editing behavior, standardizing indexing, and modernizing the build pipeline, enabling faster feature delivery and improved developer productivity.

Month: 2025-10 – IETS3.opensource delivered targeted Gradle-related improvements and a build script fix that collectively enhance build reliability and prepare for the next upgrade cycle. The work focused on Gradle 9 compatibility, build configuration hardening, and a critical fix to Maven repository URL handling in the build script. These changes reduce CI failures, improve reproducibility of releases, and set up a cleaner upgrade path for future Gradle versions.

December 2024 monthly summary for modelix.core. Focused on reliability of Content Explorer and modernization of the model-server stack. Delivered a bug fix with regression test for expandTo and completed a major platform upgrade migrating the model-server to Ktor 3, with dependency cleanups and Kotlin usage modernization. These changes reduce runtime risk, improve maintainability, and enable faster feature delivery in 2025.
