v5.0.1

Fixed issues:

• Occasionally Git checkouts failed with errors No such device or address or Terminal prompts disabled. The underlying race condition is fixed.

v4

New features:

• Introduced caching of submodules using the Namespace Git mirror
• Introduced --dissociate to detach the checkout from the Namespace Git mirror

v2

Latest release of checkout action.

v3

Fixed issues:

• The checkout action would modify the global git authentication configuration. This resulted in other git clients to fail when adding their own authentication configuration. We aligned the behavior to actions/checkout and added a cleanup step to remove the auth configuration at the end of the action.
