$ git checkout v2.6.17
-Note: moving to "v2.6.17" which isn't a local branch
-If you want to create a new branch from this checkout, you may do so
-(now or later) by using -b with the checkout command again. Example:
- git checkout -b <new_branch_name>
+Note: checking out 'v2.6.17'.
+
+You are in 'detached HEAD' state. You can look around, make experimental
+changes and commit them, and you can discard any commits you make in this
+state without impacting any branches by performing another checkout.
+
+If you want to create a new branch to retain commits you create, you may
+do so (now or later) by using -b with the checkout command again. Example:
+
+ git checkout -b new_branch_name
