# DesignStudio Array v3.1.0 Release Notes #### Release date March 2026 #### Key Highlights * New **Array Finder** tool to match up to **50k variants (rsID/cgID) or genomic loci** against Illumina commercial base content. * Supports **target entry through the UI or file upload** using a template. * Allows selection of the **species genome build** (for example, *Homo sapiens* build 37 or 38) before running the search. * Displays a **summary of overlapping targets across commercial arrays** with downloadable summary and detailed results files. * Outputs an **excludedContent** file listing targets excluded from the search. #### Resolved Issues * Improved bin assignment for Infinium I indels by categorizing insertion and deletion variants. This helps organize genetic data for accurate identification and interpretation of variants. #### Known Issues * Validation error does not occur when submitting an empty input file * Invalid characters in design names do not trigger an error * Email templates still include some irrelevant error and warning codes * Intermittent UI error may occur in Chrome --- # Agent Instructions: 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.
