Deprecation Summary

Gitaly will be deprecating two legacy variables that were originally used to configure Gitaly:

• GIT_CONFIG_GLOBAL

These variables are being deprecated in favor of utilizing the standard config.toml file for Gitaly as documented in the Gitaly Reference section of our documentation.

Breaking Change

Any users which are presently using the legacy variables mentioned above will need to update to a standard configuration method as described in our documentation.

Affected Topology

This only impacts self-hosted users.

Affected Tier

This impacts all self-hosted instances regardless of tier.
