[boost] [fsc] Boost presence in WG21 meeting at Sofia, Bulgaria

Hi everyone, We have brought some Boost advertising material to the ongoing WG21 meeting at Sofia, Bulgaria, and several Boost people are also participating there. Let me share a poster of Boost.Hash2 introduced by one of its authors, and long-time Boost contributor, Peter Dimov. Using a link to the X post so as to not burden the mailing list with a large image: https://x.com/Boost_Libraries/status/1934649592403939668 We'll be posting some other pics of the meeting during the week. Hope you like it! Joaquin M Lopez Munoz Boost Fiscal Sponsorship Committee
