Summary for 2025-03: Delivered geometry enhancements for openings and walls, introduced max distance for wall joint creation, and standardized terminology by renaming generate_windows to generate_openings. Stabilized the pipeline by skipping walls with non-calc interfaces, resolving btlx.py merge conflicts, and applying targeted fixes for topology-related wall joints and ValueErrors. Modernized the codebase with data model refactors (header vs params), modular processing element creation, and reintroducing AlignmentType, plus beam-to-element terminology updates. Improved code quality and release readiness via readability/formatting improvements, changelog prep, and multi-version bumps to 0.15.x, including LapProxy addition. Contour data paths were enhanced in BTLxWriter to support downstream rendering.

January 2025 focused on stabilizing the core compas_timber workflow, delivering a key interface refactor, and ramping up release readiness. Major work included refactoring to an Interface abstraction (replacing Interactions) and renaming API type InterfaceType to InterfaceLocation, enabling clearer semantics and future extensibility. We fixed critical rendering and correctness issues (L-detail rendering) and safeguarded against unintended side effects (avoiding in-place modification of Line.start). Release hygiene was improved with version bumps to 0.12.0 and 0.13.0, plus changelog updates and See Also references, preparing the project for predictable downstream integration. Additional quality improvements included code formatting, linting, docstring fixes, and unit-test stabilization, as well as documentation and writer/component enhancements (project name addition, BTLX write updates, and feature-skip warnings). These efforts collectively improve stability, developer velocity, and business value for downstream users and CI pipelines.
