Core2 yanked. Millions effected.
I just had 100s of CI builds fail due to libflate’s usage of core2 which as of today had all of its versions yanked on crates.io. A library which serves hundreds of millions, according to the dependents on crates.io.
Crate: https://crates.io/crates/core2
Github: https://github.com/bbqsrc/core2
Libflate issue: https://github.com/sile/libflate/issues/85
Many people are turning to no-std-io2 as an alternative.
