Bug Fixes:

• fix(stats): stats historical now returns write errors instead of silently swallowing them #1678

Deprecations:

• deprecated(auth): fastly profile, fastly sso, and fastly auth-token command trees are deprecated and will be removed in a future release. Use fastly auth subcommands instead. #1676
• deprecated(auth): --profile and --enable-sso global flags are deprecated. Use --token <name> to select a stored auth token by name, or fastly auth login --sso --token <name> for SSO. #1676

Enhancements:

• feat(auth): auth login --sso now requires --token <name> to explicitly name the stored token. This prevents accidentally overwriting tokens in multi-user SSO workflows. #1676
• feat(auth): add FASTLY_DISABLE_AUTH_COMMAND env var to hide the fastly auth command tree from help, completions, and invocation. #1676
• feat(auth): when FASTLY_DISABLE_AUTH_COMMAND is set, the --token/-t global flag is also disabled. Use FASTLY_API_TOKEN or stored config tokens instead. #1676
• feat(stats): add --field flag to stats historical to filter to a single stats field. #1678
• feat(stats): add stats aggregate subcommand for cross-service aggregated stats. #1678
• feat(stats): add stats usage subcommand for bandwidth/request usage, with --by-service breakdown. #1678
• feat(stats): add stats domain-inspector subcommand for domain-level metrics. #1678
• feat(stats): add stats origin-inspector subcommand for origin-level metrics. #1678
• feat(apisecurity/discoveredoperations): add support for 'list' and 'update' support for 'API discovery'. #1689
• feat(apisecurity/operations): add CRUD support for 'API Inventory' operations. #1689
• feat(apisecurity/tags): add API Security Operations tag support (#1688)
• feat(service/version): add support for service validation. #1695
• feat(compute/build): Block version 1.93.0 of Rust to avoid a wasm32-wasip2 bug. (#1653)
