- Added dbplyr 2.x compatibility:
- sql_select of dplyr is renamed to sql_query_select of dbplyr. tdplyr overwrites sql_query_select;
- sql_translate_env of dbplyr is changed to sql_translation. tdplyr overwrites sql_translation.
- Added support to models in PMML format for the Bring Your Own Model (BYOM) feature;
- Added support for FastExport;
- New STO Sandbox Container Utility Functions;
- Added support for Vantage Analytic Library (VAL) Functions:
- Association Rules
- Decision Tree
- Descriptive Statistics
- Factor Analysis
- Fast KMeans Clustering
- Linear Regression
- Logistic Regression
- Matrix Building
- Statistical Tests
- Reports
- Variable Transformation
- New S3 Generic function print() allows user to print the output of any of the VAL function;
- New ways to view underlying SQL:
- Function show_query() allows user to print the underlying SQL used for function execution using the output object;
- Option 'print.val.query' allows user to print the SQL while the VAL function is running. This can be used for debugging purpose.
- New configuration options provide flexibility for user to control which database must be used to create tables and views, generated by the tdplyr APIs, which are garbage collected at the end of the session. These options allow user to set the output database without re-creating context:
- 'temp.table.database.name' specifies the database to create tables into;
- 'temp.view.database.name' specifies the database to create views into.
- Updated td_test_script() function:
- Function now also allows testing on local client (outside of sandbox environment), in addition to existing node of sandbox testing;
- Function td_setup_test_env() is deprecated now. Use newly added sandbox container utility function td_setup_sandbox_env() instead.

- New Model Cataloging feature providing functionality to catalog model metadata and related information in the Model Catalog;
- Script providing an interface to run scripts in Analytics Database using Script Table Operator (STO), in two modes:
- Test/Debug mode: test user scripts locally in a containerized environment;
- In-Database Script Execution: execute user scripts in database.
- Added Vantage file management functions to install, replace, remove files in Vantage;
- New Time Series aggregate functions (ts.percentile, ts.delta_t, ts.kurtosis, ts.skew, ts.sum, ts.sd, ts.sdp, ts.var, ts.varp, ts.min, ts.max, ts.mean, ts.n, ts.describe);
- New regular aggregate functions (kurtosis, skew);
- Added support of JWT logon mechanism and Stored Password Protection feature in Context management, and using DBI::dbConnect(tdplyr::NativeDriver(), ...) to create context;
- Added support for Vantage Native Object Store (NOS) feature to explore data sets located on external object stores like AWS-S3 and Azure Blob Storage;
- Updated print() function to print only the output objects of class "tbl_teradata" of the analytic function run;
- Updated data type of returned column or value:
- td_nrow() used to return integer type, now returns bit64::integer64;
- Regular aggregate functions n() and n_distinct() used to return the count columns of integer type, now return columns of type bit64::integer64.
- Window function n() used to return the count column of integer type, now returns column of type bit64::integer64.
- Updated arguments in analytic functions. See the "Analytic Function Updates" section in Teradata Package for R Function Reference for details.
