release.sh

#!/bin/bash

# Automates the production of each release.

#
# Given a range of haproxy versions, for each version:
#
#  * Determine the SHA256 hash of the version
#  * Run build.sh with this SHA and version specified
#  * Run haproxy -v for each platform to verify success
#  * Tag and commit (but no push)

# TODO: do the same for deps, i.e. openssl, pcre2, lua.
