The following are the release notes for Tetra Cellario Connector versions 2.x.

v2.1.1

Release date: 19 December 2025

What's New

TetraScience has released its next version of the Tetra Cellario Connector, version 2.1.1. This release provides customers the option to configure Basic Authentication as an alternative to token-based authentication by using a new, optional useBasicAuth configuration parameter. By configuring this new parameter, customers can avoid potential authentication issues that may occur when they enter username and password credentials after upgrading from the Legacy Tetra Cellario Connector, which also supports Basic Authentication.

New Functionality

New Functionality includes features not previously available in the Tetra Cellario Connector.

• There's no new functionality in this release.

Enhancements

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

Basic Authentication

A new, optional useBasicAuth configuration parameter provides customers the ability to enable Basic Authentication as an alternative to token-based authentication. By configuring this new parameter, customers can avoid potential authentication issues that may occur when they enter username and password credentials after upgrading from the Legacy Tetra Cellario Connector, which also supports Basic Authentication. Token-based authentication is still the Connector's default authentication method.

For security, it's recommended that customers always use HTTPS when enabling Basic Authentication. Credentials are transmitted in encoded format and require transport-layer encryption to prevent interception.

For more information, see Configuration Parameters in the Tetra Cellario Connector documentation.

Bug Fixes

There are no bug fixes in this release.

Limitations

There are no new limitations in this release.

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 new known and possible issues in this release.

Upgrade Considerations

When upgrading from a previous Connector version, keep in mind the following:

• Customers can upgrade directly to Tetra Cellario Connector v2.1.1 from v2.1.0 or earlier with no configuration changes needed.
• Tetra Cellario Connector v2.1.0 must be used with TDP v3.6 or higher.
• Token-based authentication is still the Connector's default authentication method. If you experience authentication failures with the /token endpoint, set the useBasicAuth configuration parameter to true to enable Basic Authentication.

To install or upgrade to Tetra Cellario Connector v2.1.1, see the Tetra Cellario Connector v2 Operational Guide.

v2.1.0

Release date: 2 December 2024

What's New

This release focuses on making it easier for customers to migrate from their existing, legacy Tetra Cellario Connector to the new Tetra Cellario Connector, which uses the Pluggable Connector framework.

New Functionality

New Functionality includes features not previously available in the Tetra Cellario Connector.

• The Connector can now be configured to use a destination ID instead of the Connector's own ID when constructing the file paths that it writes to. This new functionality allows customers to upgrade to a new Connector version while preserving the same file path prefix.
• The Connector supports a new command to import Cellario events previously polled by an earlier Connector version. This command is intended specifically for migration, and so is not documented for general use. For more information, customers should contact their customer success manager (CSM) or account executive.

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 has a configuration toggle that allows customers to choose whether the file path pattern should match the pattern from their legacy Connector, or Connector.

Bug Fixes

The following bugs are now fixed:

• The Connector now continues to honor its disable TLS verification configuration option, even when behind a proxy.
• The Connector no longer fails to insert values for Cellario version information labels after being disabled and re-enabled.

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 new known and possible issues in this release.

Security

Various security updates were applied.

Upgrade Considerations

This version of the Tetra Cellario Connector is compatible as a direct upgrade from Tetra Cellario Connector v2.0.0 and must be used with TDP v3.6 or higher.

To install or upgrade to Tetra Cellario Connector v2.1.0, see the Tetra Cellario Connector v2 Operational Guide.

v2.0.0

Release date: 04 December 2023

What's New

This is the first release of the Tetra Cellario Connector, which is an improved version of the Legacy Tetra Cellario Connector. It uses the Pluggable Connector Framework to streamline the Connector’s life cycle. It also includes a new Manual Upload feature along with several other new functionalities.

New Functionality

New Functionality includes features not previously available in the Tetra Data Platform (TDP) or Tetra Cellario Connector.

• The new Pluggable Connector Framework now makes the Connector a standalone, containerized application.
• A new Manual Upload feature now allows customers to upload historical data within a specified time range. For more information, see Manual Upload in the Connector documentation.
• HRB Cellario versions are now included as metadata for files uploaded to the TDP.
• Self-signed or private Secure Sockets Layer/Transport Layer Security (SSL/TLS) certificates used by local systems are also now supported. For more information, see Manage Self-Signed and Private SSL/TLS Certificates for Pluggable Connectors.

Enhancements

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

• There are no new enhancements in this release.

Bug Fixes

No bugs were fixed in this release.

Deprecated Features

The following feature has been deprecated in the Tetra Cellario Connector v2.0.0 release:

• The Upload event bundles option will no longer be available starting with Tetra Cellario Connector v2. The feature was used to test and troubleshoot Cellario connectivity and data upload. New features available in the latest Connector version make this option unnecessary.

For more information about TDP deprecations, see Tetra Product Deprecation Notices.

Known and Possible Issues

• When processing a backlog of files from Cellario, a newly initialized Connector may fail to record the Cellario API version or assembly version in the files that are uploaded to the TDP. A fix for this issue is in development and testing and is scheduled for a future release.

Security

Various security updates were applied.

Upgrade Considerations

This version of the Tetra Cellario Connector is compatible as a direct upgrade from Tetra Cellario Connector v1.x and must be used with TDP v3.6.
