Breaking Changes

●Issue #1

Adding multiple adapters (via model.add_adapter or model.load_adapter) now raises an error instead of failing silently or incorrectly, preventing unexpected behavior when mixing adapters.

Migration Steps

  1. 1
    If you were relying on adding multiple adapters simultaneously, you must now load or add adapters sequentially, as the library explicitly prevents simultaneous addition due to complexity.

Release Summary

This patch release fixes bugs related to the new target_parameters feature, specifically ensuring existing parameterizations are preserved and preventing incorrect behavior when loading multiple adapters.
