5.20.2
(fix): When a client is constructed with both an environment and server URL
variables (e.g. region), the generated client now renders the selected
environment’s URL template instead of always using the default (first)
environment’s template. For example, Client(environment=Environment.STAGING, region="ie1") now resolves to the Staging template
(https://api.stage.ie1.example.com) rather than the Production one.
An explicitly provided base_url is no longer overridden by URL variables.
