v4.2.1 Release

· One min read

Hi all,

This release fixes the ability to search by gene name using the &loc= URL param since v4, fixes some MM tag parsing errors in BAM/CRAM files, and a couple other misc changes

Important extra note: We are rapidly iterating on a WebGPU/WebGL based accelerated rendering system for JBrowse 2, and are aporoaching a final product.

We are interested to hear from users and model organism database admins interested in beta testing and trying it out. The entire result is a relatively large code change, but we are aiming for minimal breaking changes for end users of the app.

Please contact jbrowse2@berkeley.edu for more info or visit https://github.com/GMOD/jbrowse-components/pull/5468 for an overview/comment thread
