terrapin v1.0.0

Breaking changes

Terrapin::CommandLine::PosixRunner was removed. The underlying posix-spawn gem hasn’t been supported for a while and was beginning to accumulate bugs. You can replace any usage of this with Terrapin::CommandLine::ProcessRunner, which uses Ruby’s builtin Process.spawn, and actually is more performant anyway. (#19)
