# 7.44.0 - Interop Library Upgrades

#### March 17, 2026

#### Features

* An interop library upgrade adds charting and sequencing statistics support for new flow cell types.
  * The upgrade will introduce changes to the QMetricsByLaneOut.bin file format. The QMetricsByLaneOut.bin file will now be created in the InterOpBaseSpace folder within the run folder. See this [February 2026 release notification](https://help.basespace.illumina.com/notifications#february-2026) for more information.
* Updated Run Planning to always display OverrideCycles field regardless of instrument platform, if it is supported by the selected Application.
* Added %Demux in per lane run metrics for instruments that support it (currently MiSeq i100).
* Added support for planned Microarray analyses. Configure analyses ahead of time and have them automatically launch when all required sample data is available, enabling faster and more efficient analysis workflows.
* Moved "Start an analysis" action to Microarray Data Management page.
* Added "Start another analysis" option when launching Microarray Analysis.

#### Bugs Fixed

* Fixed an issue mapping biosamples to lanes for NovaSeqX runs, which could cause biosamples to unexpectedly show as being in all lanes.
* Fixed a bug that prevented uploading block-gzipped VCF files using the UI.
* Only FASTQ generation launched by a sequencing run's owner may update the run's index metrics.
* Users without an active subscription, and who have exceeded the 1 TB storage limit, cannot accept transfers of runs or projects to their account.
* Downloader 3.3: improved error messaging when the user provides an incorrectly formatted or unsupported type of output folder.
