- * Added a new data backend to allow direct access to BAM files over
-   the web without needing to translate them to JSON with
-   `bam-to-json.pl`.  This new method of BAM access is far superior to
-   the old `bam-to-json.pl` in nearly every way, except in browser
-   compatibility.  Like the BigWig direct access backend added in
-   JBrowse 1.5.0, it works in all major browsers *except* Internet

-   It may work with Internet Explorer 10, but this has not been tested
-   yet.

  * Added a new `Alignments` track type designed to work seamlessly
    with BAM files.  This track type shows basepair differences and
