Security Notes

Bugs Fixed

  • 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)
