# December 2024 (24.3.9120)

> Release notes for CData Sync December 2024 (build 24.3.9120).

## Key Features

### Added

* Added the **Enhanced CDC** job type for the PostgreSQL and Oracle sources. This new job type uses the CData CDC engine to track and stream changes from the source database.
* Added the **Associated Jobs and Transformation** widget to connections. Now, users can see which jobs and transformations depend on the connection.
* Added the **Metadata Caching** widget to control how long Sync maintains the in-memory metadata cache for a connection before refreshing it.
* Added a **Comments** tab to the **Connections**, **Jobs**, and **Transformations** pages.
* Added new sources:
  * [Azure Blob Storage](../../connections/sources/azure-blob-storage-source)
  * [CData Connect Cloud](../../connections/sources/connect-source)
  * [Microsoft OneLake](../../connections/sources/microsoft-onelake-source)
  * [SAP Ariba Procurement](../../connections/sources/sap-ariba-procurement-source)
  * [SAP Ariba Source](../../connections/sources/sap-ariba-source-source)
* Added new destinations:
  * [Couchbase](../../connections/destinations/couchbase-destination)
  * [Microsoft OneLake](../../connections/destinations/microsoft-onelake-destination)
* Sync now monitors the disk usage where the application directory is located. When disk usage exceeds 95%, Sync pauses the scheduler until more space becomes available. Added the `suspenddiskusagethreshold` application setting to increase or decrease the threshold.
* Added more options for filtering the **Application**, **Access**, and **Audit** logs.
* Added an **Auto Map** option for when Sync builds the column mapping for reverse ETL jobs.
* Added the **Reset Strategy** option for reverse ETL jobs. This option controls how Sync reacts to primary key changes on the source table.
* Added support for replicating a table without a primary key to a table with a primary key (identity column).
* Added support for headless OAuth in Sync. Users can add the `OAuthVerifier` property to the connection to retrieve the access tokens.

### Changed

* Updated Sync to support v24 CData drivers.
* Improved error messaging that occurs when an invalid logs folder is used.
* Updated Google BigQuery so that the default **InsertMode** value is now **Upload**.
* Updated the names of Oracle and PostgreSQL to include (Native) to distinguish them from the CData Oracle and PostgreSQL connectors.
* Updated the logs folder to include dated subdirectories.
* Updated the job and transformation history tables to include the instance identifier (Id).
* Improved the error messaging that occurs when Sync cannot load a driver.
* Updated the after-job notification to include the task runtime.
* Updated the installation method for Apache Kafka to include required dependencies.
* Updated the execute-job log message to include the final status of the job (either **success** or **failure**) .

### Fixed

* Fixed an issue where Sync incorrectly logged that a job was cancelled by another instance.
* Fixed an issue where the API connector did not allow multiple filters on the same column.
* Fixed an issue where MySQL and MariaDB did not include the schema in the **Add Tasks** dialog box..
* Fixed the sorting on the **Connections** page.
* Fixed an issue with executing MERGE statements as a transformation.
* Fixed an issue where jobs were not editable when parallel processing was enabled and a Standard license was used.
* Fixed an issue where the test-connection step during job execution was not logged.
* Fixed an issue where Sync would not add multiple CHECKCACHE queries at once.
* Fixed an issue where the **Upcoming Job Runs** widget did not update the next scheduled jobs properly.
* Fixed an issue where the system locale prevented jobs from running at the correct scheduled time.
* Fixed an issue where the preview tab did not display some exceptions.
* Fixed an issue in Sync Cloud where drivers were not installed in all instances.
* Fixed an issue where environment variables were not included when job executions were retried.
* Fixed an issue that occurred when binary keys were used in change data capture (CDC) jobs.
* Fixed an issue where the row count for transformations counted against the license row limit.
* Fixed an issue where the replicate logs did not always show a warning when a string column might need to be truncated.
