3.15.0
Re-seed the per-thread RNG from system randomness when we repeatedly fail to create temporary files (#314). This resolves a potential DoS vector (#178) while avoiding
getrandom
in the common case where it's necessary. The feature is optional but enabled by default via thegetrandom
feature.For libc-free builds, you'll either need to disable this feature or opt-in to a different
getrandom
backend.
