#### Changes
(To be documented)
#### Install
\`\`\`
curl -o slirp4netns --fail -L https://github.com/${{ github.repository }}/releases/download/${tag}/slirp4netns-\$(uname -m)
chmod +x slirp4netns
\`\`\`
#### About the binaries
The binaries are statically linked with libslirp ${libslirp_version} and libseccomp ${libseccomp_version} using Ubuntu ${ubuntu_version}.
The binaries were built automatically on GitHub Actions.
The build log is available for 90 days: https://github.com/${{ github.repository }}/actions/runs/${{ github.run_id }}
The sha256sum of the SHA256SUMS file itself is \`${shasha}\` .
The binaries should be reproducible with the following command:
\`\`\`
docker buildx build \
-o /tmp/slirpbuilds \
--build-arg SOURCE_DATE_EPOCH=${SOURCE_DATE_EPOCH} \
--build-arg BUILDKIT_CONTEXT_KEEP_GIT_DIR=1 \
--platform=amd64,arm64,arm,s390x,ppc64le,riscv64 \
-f Dockerfile.artifact \
"https://github.com/${{ github.repository }}.git#${tag}"
\`\`\`
