V541 - V551
August 12, 2022
Added a new Max Categorical Dimension parameter to the AI Synthesizer configuration. This parameter controls the dimension of each column that has categorical or location encoding. If a column contains more distinct categories than this parameter, the most frequent categories are embedded as distinct one-hot vectors. The remaining categories are combined into a single one-hot vector.
Improved error identification for an invalid where clause in subsetting configuration.
On the subsetting page, for tables that were not previously in the subset, the row count is now correctly represented as unknown instead of 0.
Fixed an issue with the Tonic update option in the Tonic application.
Configuring a subset target table to include 100% of the records no longer causes an error during data generation.
Removed connection pooling from Tonic workers to address database connection issues during data generation.

Added support for partial indexes.
Fixed an issue where the configured generators were not applied.
Indexes that use the collation option are now properly recreated in the destination database.
The subsetting user interface now uses the correct terminology for MongoDB.
Improved performance for Mongo subsetting when handling downstream tables.
Fixed percentage-based subsetting for Mongo versions before 4.4.2.

Repartition and coalesce options can now be saved on Databricks.
Added support in Hive for varchar and char fields that have lengths.
V534 - V540
August 5, 2022
Enhancements
On Privacy Hub, the list of unprotected sensitive columns is replaced with a Database Tables list. The Database Tables list summarizes the protection status of each table in the source database. The Privacy Status column summarizes the protection status of the columns in the table. It provides access to the same column details and configuration options as the protection status panels at the top of Privacy Hub.
You can now filter the Workspaces view based on your assigned role in the workspace. For example, you can only display workspaces for which you are an Owner or an Editor. To use the role filter, click the filter icon in the Role column heading. For admin users, the role filter includes a Role assigned toggle to allow them to only see workspaces that they have a role in.
Other updates
Customers in the Basic license tier can now transfer ownership of workspaces and assign workspace roles to other users.
New users are now logged into Tonic immediately after they create their Tonic account.
For AI Synthesizer:
The modeling now incorporates static features for each entity across a sequence of events.
AI Synthesizer now queries to retrieve the actual minimum/maximum values of relevant columns, instead of taking the minimum and maximum of a sample of the data.
To update a license key, self-hosted instances that do not have an admin user can set the license key as the value of the TONIC_LICENSE environment variable. Tonic ignores the variable in instances that have an admin user.
The Workspaces view no longer waits for users to finish applying several new filters in quick succession before it fetches new results.
On the Job History view, fixed an issue where the copy job ID and download logs icons flashed on hover. Removed an error that flashed when job details were displayed.
Fixed the parallel processing for subsetting.

V528 - V533
July 29, 2022
Added Sequence Length Loss Factor and Order Column Loss Factor model configuration options for events data to the AI Synthesizer. Sequence Length Loss Factor indicates the importance of realistic sequence lengths in the model. Order Column Loss Factor indicates the importance of realistic column value ordering in the model.

Fixed an issue with subsetting based on a percentage of a target table.
V520 - V527
July 22, 2022
New features and enhancements
Redesigned the user experience for the subsetting feature. The new subsetting view displays a list of the source database tables and indicates whether each table is in the subset. When you click a table, the table details display in a new right-hand panel. From the details panel, you can configure target tables. You can also identify lookup tables (previously referred to as reference tables), and indicate how to handle tables that are not in the subset. For details, see About subsetting.
If subsetting is configured, when you run a data generation job, you can enable or disable subsetting. For details, see Running a data generation job.
Added latitude and longitude processing to the HIPAA Address generator.
Redesigned the Schema Changes page. The Actions list is now called Conflicting Schema Issues. Tonic provides clearer warnings when a schema change resolution will result in a change to the workspace configuration. Resolving a conflicting issue or bulk dismissing non-conflicting issues now includes a confirmation step. See Viewing and resolving schema changes.
Other updates
Renamed the Events generator to Event Timestamps.
Fixed some small display issues in the new Privacy Hub and Subsetting displays.
Improved event generation for the AI Synthesizer.

V509 - V519
July 15, 2022
New features and enhancements
We enhanced Privacy Hub to add expanded top-level metric panels. These panels show the number of unprotected sensitive columns, protected columns, and unprotected non-sensitive columns. From these panels, you can display column details, select and configure the column generator, view sample data, and add column comments. For more information, see Privacy Hub.
You can now add or update a Tonic license from the Tonic application. For a new instance, you are prompted to provide the license key before Tonic displays the login screen. Tonic displays a message when the current license is expired. The Admin Panel includes an option to update the license key. For more information, see Entering and updating your license key.
For the Address generator, added City with State and City with State Abbr to the available options for the column format. You use these options for column values such as San Francisco, California or Boston, MA.
Tonic now supports subsetting for MongoDB databases.
Workspaces can now have a description (up to 200 characters) as well as a name. Use the description field to provide additional context for the workspace and how it is used.
In the Tonic API, you can now sort workspaces based on the last generation date.
