Mar 1, 2026March 2026: Delivered a critical compatibility patch to facebookresearch/faiss addressing SWIG 4.4.0+ multi-phase initialization compilation issues. Replaced deprecated import_array() with import_array1(-1), added a helper function to normalize return types across SWIG versions, and guarded initializations with a SWIG_VERSION check to ensure the correct PyInit return type for both modern and legacy builds. This change prevents type-mismatch errors in wrapper initialization, stabilizes builds across environments, and reduces CI failures. PR 4846 details and code review by junjieqi; differential revision D94921302; merged by mnorris11. See: https://github.com/facebookresearch/faiss/pull/4846
