Enhancements
The following features and functionality have been added to the software for this release.

  • AG-1260 - A busy indicator now appears while the Chromeleon user account is being verified.
  • AG-1286 - User-deleted files during scans no longer cause unrecoverable errors.
  • AG-1723 - The culture/regional handling for dates and numbers has been improved. Context for the cultural and regional values are in the RAW JSON file.
  • AG-1899 - The TDP can push data to Chromeleon to create Sequences. This command will work when connecting through GDC and L7 Proxy.
  • AG-1965 - Password and role fields on the UI are now wider.
  • AG-1968/AG-1934 - Logging has been improved; more details have been added. Also, logs can now be over 1 MB in size.
  • AG-1992 - We've updated the logic to render report variables in RAW JSON with full object context.

    "IsNumeric":false,
    "IsString":false,
    "IsTime":true,
    "IsBoolean":false,

    "BooleanValue":null,
    "Value":"5/12/2022 4:21:53 PM +02:00"
}
  • AG-1993 - Scan errors are now available on the Management Console's Summary Page.
  • AG-2006 - Datapoint and Peak data (if available) is now shown; issues resolved by AG-2038, which changed the way it processes errors to better manage memory usage. The agent recovers from any out of memory errors and continues to process the injection(s) in a separate batch.
  • AG-2045 - We've updated the logic to render custom fields in RAW JSON so that they follow the same serialization logic as report variables.

}
  • AG-2044 - The following report variables are now part of the RAW file that is uploaded to the TDP:
    • Chromatogram Category
    • Sequence Category
    • Injection Category
  • AG-2134 - Addressed additional memory issues. Note that the agent recovers from any out of memory errors and continues to process the injection(s) in a separate batch.

Bug Fixes
Here are the bug fixes made for this version of the agent software:

  • AG-1703/AG-1936 - Domain and local Chromeleon users are now set in the same way in the UI. The "Chromeleon LDAP User" yes/no setting has been removed from the UI.
  • AG-1972 - The file name now appears in the log when the SetValue Errors are thrown.

Bug Fixes from 1.3.0 were also included.

  • AG-1909/AG-1923 - If the Tetra Chromeleon Agent cannot access remote data vaults due to a network or user permission issue, this information now appears in the logs. If the Agent cannot access a data vault, scanning for the rest of the data vaults still continues.
  • AG-2000 - The Tetra Chromeleon Agent won’t upload empty injection object due to an access permission error; instead the Agent will mark the injection as a generation error.
  • AG-2007 - If the Tetra Chromeleon Agent scans a data vault and there is no access permission for a file, the Agent logs an error message.

Deprecated Features

  • There are no deprecated features for this release.

Minor Functionality Changes

  • AG-1703 - Users authenticated and authorized using LDAP is now handled differently. There is no longer "Chromeleon LDAP User" yes/no setting. Agent Group User is the service account that runs the Tetra Chromeleon Agent while Chromeleon user/password/role used in Service Settings is used to access Chromeleon (when User Mode is enabled in Chromeleon).
