aws_request 2.1.0

Easily create, sign, and send API requests to AWS services without the hassle of implementing Signature Version 4.

2.1.0 - 2026-03-22

Changes:

• SigV4 correctness: Canonical query string matches the wire request — parameters sorted by name then value, encoding aligned with how the request Uri is built (avoids signing/query mismatches from ad hoc encoding)
• SigV4 correctness: Region and service names are lowercased in credential scope and in signing-key derivation (fixes invalid signatures when callers pass mixed-case region or service)
• New request options on AwsRequest.send / staticSend and MockAwsRequest: queryStringPairs for duplicate query parameter names (not expressible with Map); hashedPayloadIsUnsigned for S3-style UNSIGNED-PAYLOAD; useNonS3DoubleEncodedCanonicalPath for non-S3 path double-encoding rules
• signedHeaders entries are resolved case-insensitively against merged request headers
• Signing uses the same normalized canonical path as the outbound Uri (url.path)
• AwsRequestException.toString() includes stackTrace
• AwsHttpRequest.send rejects empty awsAccessKey / awsSecretKey
• Clearer error when mockRequest is true but mockFunction is null
• README: STS / temporary credentials (X-Amz-Security-Token and signing it); retries and HTTP client lifecycle; duplicate query keys with Map; corrected JSON body examples
• API docs updated for mutable credential fields, default signed headers, and the new options
• Stricter analysis_options.yaml (extends package:lints/recommended.yaml)
• Test suite expanded (SigV4 vector/conformance coverage; optional live AWS tests behind environment configuration)

2.0.0 - 2026-03-21

Breaking Changes:

• MockAwsRequest constructor now uses named parameters to match AwsRequest API
• AwsRequestException fields (message, stackTrace) are now final

Changes:

• Removed intl dependency — date formatting is now handled internally
• Fixed HTTP client resource leak in getRequest (client now always closed via try/finally)
• Fixed SigV4 timestamp race condition — getAuth now derives dateStamp from amzDate instead of a separate DateTime.now() call
• Added optional endpoint parameter for custom/non-standard AWS hostnames (S3 virtual-hosted-style, VPC endpoints, LocalStack, etc.)
• sign() return type changed from dynamic to Digest
• validateRequest now throws directly instead of returning a validation map
• Removed unused parameters (host, requestBody, timeout) from getHeaders
• getSignedHeaders no longer throws when default keys (e.g. host) are passed in signedHeaders
• Replaced type.toString().toUpperCase().split('.').last with type.name.toUpperCase()
• All tests now use mock HTTP clients instead of external network calls
• Updated CI pipeline actions (checkout@v4, codecov-action@v5)
• Updated README with SDK requirements, MockAwsRequest documentation, custom endpoints, and corrected examples
• Updated example project to current SDK and package versions
