# NextSeq 1000/2000 v2.3.1

These Release Notes describe the key changes to software components for the Clarity LIMS NextSeq 1000/2000 Integration Package v2.3.1.

## Compatibility

This version of the integration package is compatible with the following software:

* Clarity LIMS v5.3 and later (up to v6.1 only)
* NextSeq 1000/2000 Instrument Control Software (NCS) v1.5.0

## New Features

* Bug fixes

## Defect Repairs

* Fixed issue where the wrong project name is assigned to samples in the sample sheet when a run involves more than 200 samples across multiple projects.
* Fixed missing BCL convert versions in the Cloud Analysis Version custom field options in the Load to Reagent Cartridge step.

## Known Issues

* Sequencing run error triggered by disk space full on instrument causes RunParameters.xml to be empty and the run event cannot be processed on Clarity LIMS. This error is unlikely to occur as pre-run checks on the instrument check for sufficient disk space before run is started.

## Limitations

For the demultiplexing information in the Sample Details table to display correctly, the following conditions must be met:

* The DRAGEN version must be earlier than v3.9.3.
* The samples in the run must not repeat.
* The run must be for the single lane flow cell (P1 or P2).
