BREAKING CHANGES

This release of the Fastly CLI includes a significant reorganization of the commands which are used to manage the configuration of Fastly services (both Delivery and Compute services). Specifically, each of the command families listed below have been changed from fastly <family> create/delete/describe/list/update to fastly service <family> create/delete/describe/list/update. For nearly all of these command families, the previous commands are still available but are not listed in the fastly help output. In addition, invocations of the previous commands will generate a deprecation message, which includes the new command that should be used instead.

The fastly domain family of commands are the lone exception; those commands exist in both the old and new forms, but the top-level commands are used to manage 'versionless' domains (a new feature of the Fastly platform, and those commands were previously named fastly domain-v1 create/delete/describe/list/update), while the service-level commands are used to manage 'classic' domains. As a result, you will need to update any scripts or workflows which used the fastly domain create/delete/describe/list/update commands to use the fastly service domain create/delete/describe/list/update commands instead.

The command families which have been reorganized and are available in both the old and new forms are:

• acl
• aclentry
• alert
• backend
• dictionary
• dictionary-entry
• healthcheck
• imageoptimizerdefaults
• logging
• purge
• rate-limit
• resource-link
• service-auth
• service-version
• vcl

Breaking:

• breaking(domain) - service-version oriented domain commands have been moved under the service domain command. Versionless domain-v1 commands have been moved to the domain command (#1615)
