Jul 1, 2025July 2025 monthly summary for IPPL-framework/ippl. Focused on code quality and stability by addressing a compiler warning in ParticleAttrib. Key change: added the 'override' keyword to ParticleAttrib::applyPermutation and ParticleAttrib::internalCopy to ensure they correctly override virtual functions from the base class, preventing potential dispatch issues. Implemented with minimal risk changes and tied to commit 739ff4cd344c8d91ccd7d4dc94fca95a10a09162 (fix warning). Outcome includes cleaner builds, fewer shadowed/ambiguous dispatch calls, and improved maintainability for future enhancements in particle attribute handling. This work underpins downstream features and performance-critical paths by ensuring correct virtual dispatch semantics.

Jan 1, 2025January 2025 (2025-01) — IPPL framework delivered a new NullSolver option in Solver_t to support scenarios where no Poisson solver is required. This change adds a null-path option to the Solver_t variant type, enabling more flexible solver pipelines and simpler configuration for workflows that do not need Poisson solving. The update preserves API compatibility while expanding use cases and setting the stage for future performance optimizations.
