Oct 1, 2025October 2025 – Focused on enhancing bot detection coverage in matomo-org/device-detector. Delivered a targeted feature that expands the bot database with new user agents and metadata, improving the precision of bot traffic classification across client deployments. The work included updating the data sources (bots.yml and regexes/bots.yml) to include bot names, categories, URLs, and producer information for Thinkbot, Meta bots, Yandex bots, Perplexity bots, IbouBot, AddSearchBot, and TerraCotta. This reduces false positives/negatives and improves analytics fidelity.
