0.5.1

• Add --cobertura flag to support Cobertura's XML report format. (#224, thanks @mike-kfed)

• Limit the number of test threads for nextest to work around rust-lang/rust#91092. (#223)

  For subcommands other than cargo llvm-cov nextest, the same workaround has already been applied since 0.4.6.

• Replace atty with is-terminal. (#226)
