# Release Notes

Release Date: April 2026

Document Version: 3

These release notes describe the key changes to software components for the Clarity LIMS NextSeq 1000/2000 Integration Package v2.6.0.

## Compatibility

Refer to [Compatibility](https://help.connected.illumina.com/clarity-lims/compatibility#nextseq-1000-2000) under Instruments & Integrations.

## New Features

* Merge Reads PF and %PF for Read 1 and Read 2
* Replace density metric with occupancy metric
* Analysis workflow UDF default changed from Generate FastQ to BCL convert

## Defect Repairs

* When handling run events, start automated steps using master step name instead of protocol step name.
* Bug fixes for log file to reflect actual results
* Clean up unused custom primer UDF
* Accept underscore and hyphen for sample name in sample sheet

## 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.
