• New Algorithm: Omni-Optimizer for multi-modal multi-objective optimization (#776)
• Fixed GDE3 (and its MNN/2NN/PCD variants) to be deterministic for a fixed seed
• Restored CMA-ES compatibility with NumPy 2.x (now requires cma>=3.4.0)
• Documentation: complete and consistent algorithm overview; new pages for SPEA2, Omni-Optimizer, GDE3, NSDE, and NSDE-R; added PSO, G3PCX, AGE-MOEA2, D-NSGA-II, KGB, and C-TAEA to the listing; contributor acknowledgements on each community-contributed page; refreshed news
• Added a behavior-regression ("golden") test suite and extended the determinism tests across all algorithms
• Repo-wide code-quality pass: linting, formatting, and whole-package type-checking
