August 2025 monthly summary for gazebosim/gz-sim: Implemented a performance-focused asset-loading enhancement by parallelizing asset downloads with background threads by default and introducing a new CLI option --wait-for-assets to force waiting for asset downloads before startup. This delivers faster, more reliable startup for asset-heavy simulations and improves user feedback during initialization.

November 2024 monthly summary for gazebosim/sdformat.
