This fixes a bug that affected v1.7.0-v1.7.5 in which CRAM, TwoBit, and other file types would not load on jbrowse-desktop. This was due to the upgrade to webpack 5/CRA5, but is fixed in this release!

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).

Figure showing performance improvement of the noserialize improvement compared with v1.7.4, which brings the webworker performance in line with the embedded app (which does no serialization)

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)

We are excited to announce the latest JBrowse release! This has many great features including

  1. Floating feature labels, so if you are zoomed into the middle of a gene, the feature label hangs out alongside it on the left side of the screen! The results may not be pixel perfect in all cases (reverse complement labels can end up overlapping other features for example) but we hope this helps you see the labels for features that extend off the screen!

    Figure showing the feature labels floating alongside gene even when you are zoomed into the feature

  2. Upgraded build system for jbrowse-web and jbrowse-desktop to webpack 5, and added examples of using webpack 5 with embedded components. Webpack 5 results in smaller build sizes for jbrowse-web. For a typical session, amount of .js downloaded with gzip enabled in v1.6.9 is ~1.4MB, in v1.7.0 ~900kb (-500kb smaller). Without gzip enabled v1.6.9 4.8MB, v1.7.0 2.5MB (-2MB smaller). The result is largely due to better webworker bundling. See https://jbrowse.org/jb2/docs/embedded_components/ for webpack 5 examples in embedded components

  3. Optimizations and improved visualization of paired-end reads in the breakpoint split view

  4. Optimized linear synteny renderings with long CIGAR strings. These optimizations help viewing large alignments such as the CHM13-T2T-v2.0 assembly vs hg38 PAF file from https://github.com/marbl/CHM13#downloads (example here https://jbrowse.org/code/jb2/main/?config=test_data%2Fconfig_demo.json&session=share-0qD2-d_k4K&password=GF8Sk)

  5. The "Assembly selector" dropdown box now remembers your last selection, so you can more easily return to your genome of interest

This release fixes an issue with JBrowse Desktop on v1.6.6 where the first tracks to be opened would not load.

It also adds a speed optimization for BAM files (in some cases, 5x speed improvement seen in deep coverage files), and fixes a scroll issue on wiggle tracks!
