# We use the nightly version, rather than pinning to a specific version.
# foundryup does allow pinning to a specific version, via github tag:
#   foundryup --version nightly-24abca6c9133618e0c355842d2be2dd4f36da46d
# Or via git commit:
#   foundryup --commit 24abca6
# But they delete github tags frequently, and installation via commit requires
# rust and lenghty builds. So we use nightly, until versioning becomes an
# issue.

foundryup --version nightly
