  • The UploadFile stored procedure now accepts a folder as a parameter for the Path and FilePath arguments. All the files inside that folder are uploaded to the destination path in parallel. This is not recursive, so the files in the sub folders will not be uploaded.

  • The DeleteObject stored procedure now has an additional feature where you can specify a folder and delete only the files inside that folder.

  • Changed the Primary Key Column for the ADLSGen2.Resources view from ETag to Name. ETag is not unique, but Name is.

  • Added the Resources.Directory column to the ADLSGen2 Schema. This column supports server side filtering and can be used to list the files in the specified Directory.
  • Added support for the STRING_SPLIT table-valued function in the CROSS APPLY clause.
  • Added the KeySeq column to the sys_foreignkeys table.
  • Added the new sys_primarykeys system table.
  • 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 vs te predicate. Ie: 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. Ie: WHERE col > L_LAST_MONTH(). This will continue to resolve to the same values that previously were calculated in the criteria. Note that the "L_" prefix will only work in the predicate - it not available for the projection.
  • Added the TCP Logging Module for the logging information happening on the TCP wire protocol. The transport bytes that are incoming and ongoing will be logged at verbosity=5.

  • Added support for the AzureServicePrinciple authentication scheme.
  • Added support to authenticate submitting JWT certs instead of the OAuthClientSecret for the AzureServicePrinciple and AzureAD authentication schemes.
  • Added support for handling client side formulas during insert / update. For example: UPDATE Table SET Col1 = Concat(Col1, " - ", Col2) WHERE Col2 LIKE 'A%'
  • Updated how display sizes are determined for varchar primary key and foreign key columns so they will match the reported length of the column.
  • Non-conditional updates between two columns is now available to all drivers. For example: UPDATE Table SET Col1=Col2

  • Reduced the length to 255 for varchar primary key and foreign key columns.
  • Updated implicit and metadata caching to improve performance and support for multiple connections. Old metadata caches are not compatible - you would need to generate new metadata caches if you are currently using CacheMetadata.
  • Updated index naming convention to avoid duplicates
  • Updated and standardized Getting Started connection help.
  • Added the Advanced Features section to the help of all drivers.
  • Categorized connection property listings in the help for all editions.

  • Kerberos authentication is updated to use TCP by default, but will fall back to UDP if a TCP connection cannot be established
