New distributions supported: macOS High Sierra and Ubuntu 17.10
Performance Improvements: Greater than 10x performance improvement when driver converts to/from UTF-8/16.
Always Encrypted support for BCP API
New connection string attribute UseFMTOnly causes driver to use legacy metadata in special cases requiring temp tables.
Support for Azure SQL Managed Instance (Extended Private Preview).
There are a number of differences when using Managed Instance:
- FILESTREAM is not supported
- Local filesystem access is not supported, but required for things like tracefiles
- Create UDT from local path is not supported
- Windows Integrated Authentication is not supported
- DTC is not supported
- 'sa' account is not present (default account is called 'cloudSA')
- TDS token ERROR (0xAA) returns incorrect server name
- Special characters in database name are not supported
- ALTER DATABASE [dbname1] MODIFY NAME = [dbname2] is not supported
- The error messages are always shown in English, regardless of language settings (same as Azure)
13.1, for SQL Server on Linux and macOS, May 2017
ODBC Driver 13.1 for SQL Server adds support for Always Encrypted and Azure Active Directory when used in conjunction with Microsoft SQL Server 2016.
New distributions supported: OS X 10.11 and macOS 10.12 are supported in the first release of the ODBC Driver on macOS. Ubuntu 16.10 is now also supported, along with Red Hat 6, 7, and SUSE 12. Each platform has a platform-relevant package (RPM or DEB) to ease installation and configuration. See Installing the Driver for installation instructions.
unixODBC Driver Manager 2.3.1 Support Changes: The ODBC driver no longer depends on custom packaging for the unixODBC driver manager (except on RedHat 6), and instead relies on the distribution package manager to resolve the UnixODBC dependency from the distribution's repositories.
BCP API Support: The Linux and macOS ODBC driver now supports the use of the BCP API functions (bcp_init, etc.)
13.0, for SQL Server on Linux
With Microsoft ODBC Driver 13.0 for SQL Server, SQL Server 2014 and SQL Server 2016 are now also supported.
New distributions supported:
Ubuntu is now supported, along with Red Hat and SUSE. Each platform has a platform-relevant package (RPM or DEB) to ease installation and configuration. See Installing the Driver for installation instructions.
unixODBC Driver Manager 2.3.1 Support: In addition to a newer driver manager, there is also a package for installing this dependency that eases installation and configuration.
Transparent Network IP Resolution: Transparent Network IP Resolution is a revision of the existing Multi-Subnet Failover feature that affects the connection sequence of the driver in the case where the first resolved IP of the hostname does not respond and there are multiple IPs associated with the hostname.
TLS 1.2 Support: The Microsoft ODBC Driver 13.0 for SQL Server on Linux now supports TLS 1.2 when secure communications with SQL Server are used.
