Boost Mission

development of high quality, expert reviewed, legally unencumbered, open-source libraries,
inspiring standard enhancements, and
advancing and disseminating software development best practices.

It does this by fostering community engagement, nurturing leaders, providing necessary financial/legal support, and making directional decisions in the event of Boost community deadlock.

Equally important to our mission is the guidance provided by our shared values. These are transparency, inclusivity, consensus-building, federated authorship, and community-driven leadership.

Why Use Boost? In a word, Productivity. Use of high-quality libraries like Boost speeds initial development, results in fewer bugs, reduces reinvention-of-the-wheel, and cuts long-term maintenance costs. And since Boost libraries tend to become de facto or de jure standards, many programmers are already familiar with them.

New Library for 1.89 - Boost.Bloom

Posted on Aug 15th, 2025 by Robert Beeston

Boost.Bloom is a header-only C++ library for efficient probabilistic set membership testing.

It allows you to check whether an element might be in a set, with minimal memory overhead and no false negatives, ideal for high-throughput scenarios like caching, deduplication, and indexing.

The filter is highly space-efficient, and can dramatically reduce the cost of negative lookups in systems where accessing the full data set is expensive.
