* This version fully supports connections to all Teradata Vantage systems (VantageCloud Lake, VantageCloud Enterprise, and Vantage Core.)
* New feature: The In-Vantage Scripting recipe has been expanded to include using the Open Analytics Framework and the APPLY Table Operator in VantageCloud Lake systems. The recipe adjusts to the corresponding suitable interface depending on the Teradata Vantage system type where the inputs reside.

## Versions 2.3.11, 2.3.12 (July 2023)

* Dataiku 12 is incompatible with preceding Dataiku releases. This plugin release begins support for both Dataiku 11 (or older) and 12 (and newer) releases. For as long as the plugin supports concurrently these 2 different Dataiku release families, the plugin will be using the efix version number to designate compatibility with the corresponding Dataiku release family. To this end: Releasing distinct versions for Dataiku 11 or older (v.2.3.11) and Dataiku 12 (v.2.3.12) platforms. Version 2.3.0 is otherwise identical to 2.3.11.

## Version 2.3.0 (May 2023)

* Support for the Unbounded Array Framework (UAF) time series functions.
* Bug fix: BYOM recipes did not by default run queries in TERA mode.
* Bug fix: If the user should have inadequate permissions to access a recipe, the plugin no longer produces a generic "External Code Failed" error; a permissions-related message is now issued upon accessing a recipe, instead.

* Bug fix: An issue prevented non-admin users from running plugin recipes.

## Version 2.2.0 (December 2022)

* Bug fix: Analytic functions recipe: A naming mismatch caused errors when executing functions that use the "Number Of Splits" argument.
* Bug fix: BYOM scoring recipe: Now correctly uses the name of a Vantage table to reference the testing Dataset instead of the Dataiku Dataset name.
* Bug fix: BYOM model export recipe: Now correctly addresses the scenario where a user might choose a connection whose credentials mode is “per user”.
