This is a breaking change. It defines the new environment variable named _COSMO_FDS_V2 which is used for inheriting non-stdio file descriptors on execve() or posix_spawn(). No effort has been spent thus far integrating with the older variable. If a new binary launches the older ones or vice versa they'll only be able to pass stdin / stdout / stderr to each other therefore it's important that you upgrade all your cosmo binaries if you depend on this functionality. You'll be glad you did because inheritance of file descriptors is more aligned with the POSIX standard than before.
