• Pull Request #1209 - fixed a bug when fetching varbinary max fields as char or wide chars

Limitations

• No support for inout / output params when using sql_variant type
• No support for inout / output params when formatting decimal values
• In Linux and macOS, setlocale() only takes effect if it is invoked before the first connection. Attempting to set the locale after connecting will not work
• Always Encrypted requires MS ODBC Driver 17+
  • Only Windows Certificate Store and Azure Key Vault are supported. Custom Keystores are not yet supported
  • Issue #716 - With Always Encrypted enabled, named parameters in subqueries are not supported
  • Issue #1050 - With Always Encrypted enabled, insertion requires the column list for any tables with identity columns
  • Always Encrypted limitations

Known Issues

• This release requires ODBC Driver 17.4.2 or above. Otherwise, a warning about failing to set an attribute may be suppressed when using an older ODBC driver.
• Connection pooling on Linux or macOS is not recommended with unixODBC < 2.3.7
• When pooling is enabled in Linux or macOS
  • unixODBC <= 2.3.4 (Linux and macOS) might not return proper diagnostic information, such as error messages, warnings and informative messages
  • due to this unixODBC bug, fetch large data (such as xml, binary) as streams as a workaround. See the examples here
