JBrowse 1.9.8 maintenance release

JBrowse 1.9.8 has been released, with fixes for some minor issues, a performance improvement when many HTML-based tracks are open, and a new yScalePosition configuration option for all tracks can can be set to “left”, “right”, or “center” to change where the y-axis scale is displayed.

Changes in this release:

  • Removed “XX has no data for this chromosome” popup warning message.
    It was just annoying and not very useful.
  • Added an optional “yScalePosition” element to track configs that
    allows configs with Y axes to have those axes positioned on the
    left or right side of the view, as well as in the center. Thanks
    to Alexis Grimaldi for making this change.
  • Fixed a bug in which NCList-based tracks display with an error for
    reference sequences on which they have no data. Thanks to Michael
    Axtell for pointing this out.
  • Improved GFF3 handling in the File->Open tool, fixed a bug in the
    GFF3 parser in which an empty (.) source column caused the GFF3
    parser to crash.
  • Improved scrolling speed when many HTML feature tracks are active.
  • Fixed a bug in which the browser can fail to start for a reference
    sequence that has never been seen before.
  • Fixed a confusing behavior in JBrowse/Store/SeqFeature/REST in
    which the URLs it constructs to fetch from did not always have a
    ‘/’ where one would expect. Thanks to Alex Kalderimis for pointing
    this out.
