The following are the Legacy Tetra IDBS E-Workbook Connector release notes for versions 1.4.x.

v1.4.1

Release date: 7 July 2026

What's New

TetraScience has released its next version of the Legacy Tetra IDBS E-Workbook Connector, version 1.4.1. This patch release introduces a configurable DataWeave buffer size setting that allows administrators to handle large data payloads without encountering buffer limit errors. It also includes fixes for SSO configuration validation and multiple matching results selection.

New Functionality

New Functionality includes features not previously available in the Tetra Data Platform (TDP) or Tetra IDBS E-Workbook Connector.

• The Connector now includes a configurable Max stdout / stderr buffer setting for DataWeave script execution. This setting is available in the Connector's Settings page under the DataWeave section as a dropdown with preset values of 1, 2, 4, 8, 16, and 32 MiB. The default buffer size is 8 MiB, which is sufficient for most IDBS workflows. Administrators can increase this value if DataWeave scripts process large query or result payloads (for example, large Elasticsearch JSON from IDBS views) that exceed the buffer limit. For more information, see Legacy IDBS E-Workbook Connector - Admin Configuration.

Enhancements

There are no enhancements in this release.

Bug Fixes

The following bugs are now fixed:

• The Connector now validates that all SSO configuration fields contain non-empty values before presenting an SSO login option. Previously, incomplete SSO configurations with empty fields could appear valid, which prevented users from logging in successfully.

• When a DataWeave search returns multiple matching results, the Connector now displays each result clearly and allows users to select the correct one using radio buttons. Previously, the radio button selection did not function correctly when multiple matches were found, making it difficult for users to choose between results.

Deprecated Features

There are no new deprecated features in this release. For more information about TDP deprecations, see Tetra Product Deprecation Notices.

Known and Possible Issues

There are no known and possible issues in this release.

Upgrade Considerations

The instructions in Legacy IDBS E-Workbook Connector - Admin Configuration are updated to include the new DataWeave buffer size configuration setting.

No additional upgrade steps are required. The default buffer size of 8 MiB takes effect automatically without administrator action.

v1.4.0

Release date: 30 October 2024

What's New

TetraScience has released its next version of the Legacy Tetra IDBS E-Workbook Connector, version 1.4.0. This release introduces a new DataWeave Template Tracker, which can help customers better understand how often users import results from the Tetra Data Platform (TDP) into specific IDBS spreadsheets. The v1.4.0 release also expands options for establishing a network connection between the Connector and the TDP by providing support for container-level HTTPS and HTTP proxies.

New Functionality

New Functionality includes features not previously available in the Tetra Data Platform (TDP) or Tetra IDBS E-Workbook Connector.

• A new DataWeave Template Tracker records each time the Connector runs specific DataWeave templates. The DataWeaver template tracker records the following information:
  • Template ID
  • Template name when the template was run
  • IDBS user who invoked the template

Enhancements

Enhancements are modifications to existing functionality that improve performance or usability, but don't alter the function or intended use of the system.

• The Connector now supports using HTTPS and HTTP proxies configured at the container level. For more information, see Tetra IDBS E-Workbook Connector Installation.

Bug Fixes

The following bugs are now fixed:

• An issue in the TDP v4.1.0 release that caused the Tetra IDBS E-Workbook Connector to not give correct privileges to users logging in to the Connector using TDP credentials rather than SSO is now resolved.
• The DataWeave Editor no longer shows a control for batch size on library templates, because the templates aren't affected by batch size settings.

Deprecated Features

There are no new deprecated features in this release. For more information about TDP deprecations, see Tetra Product Deprecation Notices.

Known and Possible Issues

There are no known and possible issues in this release.

Security

Various security updates were applied, including the following:

• Various Connector dependencies have been upgraded or removed to patch security vulnerabilities.
• The Connector no longer defaults to trusting self-signed TLS certificates. To revert to the legacy TLS Certificate behavior, or for instructions on how to add a certificate to the Connector, see Tetra IDBS E-Workbook Connector Installation.

Upgrade Considerations

(Last updated: 27 November 2024)

The instructions in Tetra IDBS E-Workbook Connector Installation are updated to include support for HTTPS and HTTP proxies as well as the changes to the default TLS certificate behavior.

To set or change the proxy environment variables for an existing container image v1.4.0 or higher, do the following:

1. Delete the existing Docker container.
2. Recreate the Docker container by using your previous container image and the appropriate proxy environment variables. For instructions, see Additional Container Options.
3. Start the new container.
