Boost C++ Libraries

Template-heavy C++ compiles slowly because the AST explodes. Matheus Izvekov optimized how Clang represents certain types so the AST builds leaner. Result: 5–7% faster builds measured on stdexec and Chromium. Fewer nodes, fewer indirections → faster compiles.

Real-world: 32.4M ops/sec vs 25.3M (28% lift). Typical benches: 2.5–3x faster than std. Let numbers make the call. go.boost.org/46ZLNvX #cplusplus #opensource #boost

concurrent_flat_map: 2–2.5x ops/sec vs tbb::concurrent_hash_map in skewed workloads. Lock‑free probe; per‑group spinlocks. go.boost.org/4n6xHNL #cpp #opensource #boost

flat_map wins 14–29% across diverse workloads; up to 3.2x fewer comparisons on unsuccessful lookups via overflow‑byte early stop. go.boost.org/4q4vtBv #cplusplus #opensource #boost

Need max performance? Use unordered_flat_map. Need stable refs? unordered_node_map. Multi-threaded? concurrent_*. Ship the right tool, not the default. go.boost.org/4h6Khv8

Boost made a cameo in the final #CppCon keynote.
Thanks to @matt.godbolt.org for the mention, and to the C++ community for keeping Boost strong!

Great libraries, great conference.
Visit the new boost.org

Check out the new Boost. Fewer dependencies, faster build times, modern libraries. We never stopped growing! #cppcon

At #CppCon, we've been showing off some of our latest and greatest! Here's a rundown:

Math - boost.org/libs/math
Redis - boost.org/libs/redis
Bloom - boost.org/libs/bloom
Hash2 - boost.org/libs/hash2
Parser - boost.org/libs/parser
MQTT5 - boost.org/libs/mqtt5
Unordered - boost.org/libs/unordered

Boost.Math: making sure C++ developers never feel like fish out of water (right, Austin?). #CppCon

Who does the artwork?

Every card features original, commissioned artwork from Bob Ostrom, an amazing illustrator and cartoonist featured in over 250 children's books.

How can I get notified?

Follow Boost on BlueSky for up to date news related to the Boost Collectible Card Game and the Boost C++ Library collection.

Play continues to the next Feature, and the overall game goes to the player who ships the agreed number of Features first or reaches the session’s victory condition. The rules are intentionally quick to learn, but the mix of card synergies, tradeoffs, and timing rewards deeper strategy.

Some Events are persistent and remain in play until cleared, just like long-running issues in real projects. You win a Feature the moment your tableau meets or exceeds all of its listed requirements.

On your turn you draw, then lay out Library and Tool cards to your table, adding their stats together to meet your Feature’s requirements. Events can reshape the board by adding constraints, accelerating progress, or throwing curveballs that force you to rethink your plan.

How to play?

Each player starts with a deck and a face-up Feature (chosen by their opponent) that they are trying to build. A Feature is a small project goal with clear stat requirements, such as a target total in Speed, Reliability, Efficiency, or other engineering-flavored attributes.

Are cards all the same?

Every card is labeled with its origin and a timestamp. For example, the initial card packs obtained at CppCon 2025 are labeled so the cards with this marking can only be obtained at that conference, in the specified year.
