- Connect (4.0.109.0)
- Seven new APIs for managing custom metrics, including create, describe, update, and delete. Using Custom Metrics, customers of Amazon Connect Customer can tailor analytics dashboards to their needs by applying custom thresholds, filters, and calculations to one or more out of the box measurements.

- Amazon A2I entered maintenance mode in July 2026 and now rejects StartHumanLoop requests from accounts that it does not recognize as existing customers. This update adds a corresponding note to the HumanLoopConfig parameter documentation so that the API Reference and SDK docs explain this behavior.
- Core 4.0.101.0
- Added
IRequest.PrecomputedContentSha256, a caller-supplied body hash thatAWS4Signeruses verbatim (when payload signing is enabled) in place of reading the request body. - Added
SigV4SigningHandler, aSystem.Net.Http.DelegatingHandlerin theAmazon.Runtime.Signingnamespace that SigV4-signs each outbound request. Install it on anHttpClient(directly or viaIHttpClientFactory) to sign requests transparently. It is a thin layer over the standaloneAWSSigV4Signerfacade, resolves credentials on every send, and supports per-request region/service/payload-signing overrides viaHttpRequestMessage.Options. - Added a public standalone SigV4 request signing API in the
Amazon.Runtime.Signingnamespace (AWSSigV4SignerwithSign/SignAsyncfor header signing andPresign/PresignAsyncfor presigned URLs, plus theAWSSigningRequest,AWSSigV4Parameters,AWSSigningResult, andPresignResulttypes). This lets callers sign an arbitrary HTTP request with SigV4 without constructing internal signer types. - Added time-accepting overloads of
AWS4Signer.SignRequestandAWS4PreSignedUrlSigner.SignRequestthat take an explicitsignedAt, enabling deterministic signing. Existing overloads are unchanged and delegate to these with the previously computed default time. - All service and extension packages updated to require new Core
