hmmm, but wasn't the low-entropy seeding limited to the bx-seed codebase, or has a similar problem been found in the libbitcoin dev toolkit?
No. libbitcoin is split into 11 different repositories, the flawed rng was in libbitcoin-system, used all over the place the supposed thread safety bug that motivated the change was observed in P2P networking. But I believe bx-seed is the one and only generate-your-private-key thing in the whole caboodle.
The division of the software into many repositories probably contributes to the lack of review/oversight and wider participation in development there.
