* Recent versions of etcd no longer support the /v3alpha/ endpoint
* It's probably better to skip directly to the /v3/ endpoint
as a default.
* Note that this probably means a new minor version of tooz, while
the behaviour can be worked around in config, this is enough to
break existing systems on upgrade.
* Updated the test to test backwards compatibility.
* Updated the tests to use etcd 3.3.27, unfortunately we need
a newer version of pifpaf that supports 3.4 before the default
api can be used.
* The etcd backend tests have been removed: the deprecated backend
uses the v2 api which is no longer provided - a future commit
should remove the deprecated backend. The etcd3gw backend is the
replacement.
This fix is required in pifpaf, but it's not in any release:

upgrade:
|
|
- |
|
|
This version of tooz defaults to the `v3` endpoint for the `etcd3gw`
|
|
backend. The previous behavior can be restored by appending
|
|
`?api_version=v3alpha` to the coordination URL. The `v3alpha` and
|
|
`v3beta` endpoints have been deprecated by upstream etcd.
