Release 1.88.0 of the Boost C++ Libraries is now available. These open-source libraries work well with the C++ Standard Library, and are usable across a broad spectrum of applications. The Boost license encourages both commercial and non-commercial use. The release contains two new libraries: * Hash2: An extensible hashing framework, from Peter Dimov and Christian Mazakas. * MQTT5: MQTT5 client library built on top of Boost.Asio, from Ivica Siladić, Bruno Iljazović, and Korina Šimičević. as well as numerous enhancements and bug fixes for existing libraries.

Hello, I have two questions about the Boost.Hash2 library: 1. Which xxHash algorithm is implemented exactly (I somehow couldn't see this in the documentation). As far as I know there are four: XXH32, XXH64, XXH3_64bits and XXH3_128bits [1]. Boost.Hash2 implements xxhash_32 and xxhash_64, but is this the old xxHash version (XXH32, XXH64) or the new xxHash version 3 (XXH3_64bits, XXH3_128bits)? 2. Is there a specific reason why the old cstdio library and not iostream/fstream from C++ is used in the examples [2]? I'm not that experienced with C++ programming yet - so the questions might be a bit “stupid”, but I would still appreciate an answer!

https://github.com/boostorg/hash2/blob/14a374ea904cf7a58cfef65e11d1de067fe0d... matching https://github.com/Cyan4973/xxHash/blob/dd11140c2dc5d53a3c0a949d67af7f40f546... Seems to suggest that 64bit hash is XXH64.
2. Is there a specific reason why the old cstdio library and not iostream/fstream from C++ is used in the examples [2]?
I think there is no reason.
