# Release Notes

Last Updated: November 2024

Release Date: September 2023

Document Version: 2

These release notes describe the key changes to software components for the Clarity LIMS NextSeq 1000/2000 Integration Package v2.4.0.

## **Compatibility**

Refer to [Compatibility](/clarity-lims/instruments-and-integrations/compatibility.md#nextseq-1000-2000) under Instruments & Integrations.

## **New Features**

* Updates third-party dependency libraries.

## **Defect Repairs**

* The NextSeq 1000/2000 sample sheet now reflects the submitted sample name instead of the library name.
* The scope for the JWT token in the integration is restricted.
* Fixed SIS core service not being properly registered in systemctl.

## **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.
* [Sample sheet and planned run generation will fail](/clarity-lims/known-issues/integration/set9561-sample-sheet-generation-fail-samples-with-qc.md) if any of the samples in the pools has been assigned QC flag in prior steps before entering the Load to Reagent Cartridge step.

## **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).

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.connected.illumina.com/clarity-lims/instruments-and-integrations/nextseq1k2k/nextseq1k2k-v2.4.0/nextseq1k2k-v2.4.0-release-notes.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
