|
| 2021-07-23 | 21.0.7874 | General | | Changed | - Updated the Literal Function Names for relative date/datetime functions. Previously, relative date/datetime functions resolved to a different value when used in the projection as opposed to the predicate. For example: SELECT LAST_MONTH() AS lm, Col FROM Table WHERE Col > LAST_MONTH(). Formerly, the two LAST_MONTH() methods would resolve to different datetimes. Now, they will match.
- As a replacement for the previous behavior, the relative date/datetime functions in the criteria may have an 'L' appended to them. For example: WHERE col > L_LAST_MONTH(). This will continue to resolve to the same values that were previously calculated in the criteria. Note that the "L_" prefix will only work in the predicate - it not available for the projection.

|
| 2021-04-16 | 21.0.7776 | ADO.NET | | Changed | - Separated the ADO.NET Provider assembly and Entity Framework Core 5 Nuget packages.
- Single precision floating point numbers are now reported as with the Data Type Name as "real". Double precision floating point numbers now have their Data Type Name reported as "float". This change does not impact the actual data types of these columns - only the reported data type name.
- Separate EFCore 3.0, 3.1 and EFCore 5 dlls are now shipped with the driver. The 2.0 and 2.1 EFCore dlls are removed.
|

|
| 2021-04-16 | 21.0.7776 | General | | Changed | - Updated implicit and metadata caching to improve performance and support for multiple connections. Old metadata caches are not compatible - you need to generate new metadata caches if you are currently using CacheMetadata.
|
| 2021-04-16 | 21.0.7776 | General | | Changed | - Updated index naming convention to avoid duplicates.
|
| 2021-04-15 | 21.0.7775 | General | | Changed | - Kerberos authentication is updated to use TCP by default, but will fall back to UDP if a TCP connection cannot be established.
