For platforms on which OpenSSL libraries are bundled, the linked OpenSSL library for Connector/ODBC has been updated to version 1.1.1g. Issues fixed in the new OpenSSL version are described at https://www.openssl.org/news/cl111.txt and https://www.openssl.org/news/vulnerabilities.html. (Bug #31296688)
The MSI installer now checks for the Visual 2019 C++ runtime, and aborts if this required runtime is not installed.
This is also the first version that requires Visual 2019 C++ runtime, when before the 2017 version was also supported. (Bug #31102234)
Only a single value was being inserted instead of the array, with SQLParamOptions. (Bug #30591722)
The SUM aggregate function did not function with ADO. (Bug #30277891, Bug #96642)
Added a workaround to account for a limitation in the iODBC SQLGetPrivateProfileString() implementation as previously DSN options could be lost. iODBC is most commonly used on macOS. (Bug #27851681)
