Amazon S3 pins its wire API to a stable dated version and evolves additively; it does not deprecate operations behind RFC 8594 Sunset headers. versioning: scheme: dated-api-version current: '2006-03-01' control_api_version: '2018-08-20' mechanism: >- The S3 REST API version is fixed at 2006-03-01 and encoded in the SDKs/signing, not negotiated per request. New capabilities are added additively (new headers, query subresources, and operations) without breaking the dated contract. S3 Control uses the 2018-08-20 version; S3 Tables is a newer additive surface. docs: https://docs.aws.amazon.com/AmazonS3/latest/API/Welcome.html deprecation: policy_url: https://docs.aws.amazon.com/AmazonS3/latest/API/WhatsNew.html changelog: https://docs.aws.amazon.com/AmazonS3/latest/API/WhatsNew.html sunset_header: false notes: >- S3 favors long-lived backward compatibility over removals. Notable retirements are handled at the feature level and pre-announced with long timelines (e.g. path-style request endpoints deprecated in favor of virtual-hosted-style; BitTorrent support removed; ListObjects (v1) superseded by ListObjectsV2 but still served). Deprecations are communicated via the What's New feed and AWS blog, not via Deprecation/Sunset response headers. sla: url: https://aws.amazon.com/s3/sla/ monthly_uptime_targets: S3 Standard: "99.9%" S3 Standard-IA / One Zone-IA / Intelligent-Tiering / Glacier tiers: "99.9% (per-class commitment)" service_credits: true notes: >- S3 publishes a monthly-uptime-percentage SLA with tiered service credits. Durability is designed for 99.999999999% (11 nines) but is a design target, not an SLA metric. status_page: https://health.aws.amazon.com/health/status rate_limits: rate-limits/amazon-s3-rate-limits.yml superseded_operations: - name: ListObjects (GET Bucket, v1) superseded_by: ListObjectsV2 (openapi/amazon-s3-rest-api-openapi.yml#ListObjectsV2) evidence: AWS recommends ListObjectsV2 for all new development; v1 remains available for compatibility. deprecated_operations: []
