v1.7.5 Release

· 2 min read

We are pleased to present the release of v1.7.5

This release includes two major improvements

  • Ability to index tracks for searching by gene names in JBrowse Desktop. This let's users choose per-track indexes in the add track widget interactively, or index them after-the-fact using the track menu.
  • Removed serialization of BAM/CRAM features for pileup tracks which brings large performance benefits for jbrowse-web and jbrowse-desktop. Previously, all the BAM/CRAM features were serialized across the RPC boundary in jbrowse-web and jbrowse-desktop, but this was an expensive and memory intensive operation. Now, the BAM/CRAM features are not serialized, but the main thread has to manually request any data it needs from the worker after rendering (e.g. when we click a feature).

This release also fixes a bug with using trix indexes created by jbrowse text-index in v1.7.0-v1.7.4 (with the adjustable prefix size)
