Amazon Athena ODBC Driver 2.4.0.0

Fixes

• Fixed an issue that caused SQLTables and SQLColumns to omit tables beyond the first 200 in a schema when a metadata results page was empty.
• Fixed an issue that caused empty string filter patterns from ADO.NET applications such as Power BI to return zero rows instead of all rows.
• Fixed an issue that caused SQLColumns to fail on column types that the driver does not recognize, such as uuid or json. These columns are now reported as VARCHAR.
• Fixed an issue that caused connections that use the SageMakerBrowserIdc authentication plugin to hang when the SSOOIDCEndpointOverride or SSOEndpointOverride parameter was set.
• Fixed an issue that caused connections through a proxy server to fail with DNS resolution errors when the proxy performs DNS resolution. HTTP clients that the AWS SDK creates internally now use the proxy configuration from your DSN.

Note
On Windows, the driver now verifies SSL certificates against the Windows system certificate store and does not use the TrustedCerts parameter.
- Fixed an issue that caused TLS certificate verification to fail on some Linux distributions when the TrustedCerts parameter was not set. The driver now locates the CA bundle at runtime and honors the CURL_CA_BUNDLE and SSL_CERT_FILE environment variables.
- Fixed an issue that caused the driver to send requests to identity providers without a User-Agent header.

Important …

Fixes
- Fixed an issue that caused some browser-based authentication requests to fail because of a missing Content-Length header.
- Fixed an issue that caused query parameters to be truncated when you use SQL_C_WCHAR bindings.
- The license file now includes a reference to the AWS Service Terms.

Improvements
- SageMaker authentication – Added support for the SageMaker authentication plugins SageMakerBrowserIdc and SageMakerIam. You can now connect to your SageMaker projects and work with the data from your preferred third-party tool. For more information, see SageMaker Browser IDC and SageMaker IAM.
- Multi-catalog browsing – Added multi-catalog browsing support for lakehouse features. The driver can now discover and connect to all catalogs in federated catalog environments, enabling use of S3 Tables and catalog federation through Amazon Athena.
- macOS universal installer – The macOS driver is now distributed as a single universal binary that supports both ARM and Intel architectures, simplifying installation across all Mac hardware.
- HTTP client migration – Removed the libcurl dependency from ODBC binaries by migrating to the AWS SDK CRT HTTP client. The CRT client uses the platform's native TLS stack and system trust store, improving connection reliability and eliminating transitive dependencies on OpenSSL and zlib.
Fixes
- Added ExternalId support for STS AssumeRole for cross-account role assumption. The ExternalId is read from the AWS profile configuration.
