June 2026: GPU visibility fix for ROCm in HIP_VISIBLE_DEVICES implemented for unsloth. Ensured only HIP_VISIBLE_DEVICES is set and ROCR_VISIBLE_DEVICES cleared to prevent double masking. Verified on 2x Radeon AI PRO R9700 (gfx1201) with ROCm 7.1.1; GPU throughput improved from ~7.7 tok/s (CPU fallback) to ~78 tok/s. Addresses #6175; related PR #6176.

May 2025 monthly summary for prisma-engines: Focused on extending the query compiler with the relationJoins preview and hardening test coverage. Implemented Relation Joins preview to enable testing and usage of multiple relation load strategies ('query' and 'join'), updated CI workflows and build targets to support the new testing scenarios, and added a regression test to prevent a previously fixed panic in the query compiler's data mapper, including test clustering fixes and a new Item model to support aggregation queries. These changes improve testing reliability, reduce regression risk, and provide clearer business value by enabling more robust data loading strategies.
