I'm pleased to announce the release of JBrowse 1.6.5, containing some small new features, plus fixes for some issues in the [1.6.4 release](http://jbrowse.org/jbrowse-1-6-4-bugfix-release/ "JBrowse 1.6.4 bugfix is also coming along very soon, with a (we hope!) very impressive set of new features. Stay tuned.release").
Files for download:
* [JBrowse-1.6.5-min.zip](/wordpress/wp-content/plugins/download-monitor/download.php?id=23 "download JBrowse-1.6.5-min.zip") - 2.8M

Changes in this release:
* The location box now shows the **length of the currently visible**
** region** in parentheses. For example: `ctgB:1244..3566 (2.32 Kb)`.
Thanks to Karsten Hokamp for the suggestion!
* The **arrow keys** on the keyboard can now be used to pan and scroll
around the genome view.
* Wiggle track mouseover cursors now display the score with only 6
significant digits, avoiding confusion over approximations
introduced by scores being converted to IEEE floating-point numbers
(as for BigWig files) and back to text.
* The faceted track selector now renders any HTML that may be present
in the track metadata by default. To turn this off, it now accepts
an `escapeHTMLInData` option that, if set to `true` or `1`, will
not render the HTML, but will instead display the raw code
(issue #145).
* Upgraded to a more recent version of jszlib, which contains some
important bugfixes (issue #157).
* Fixed bug dealing with very large regions with the same value in
canvas-based Wiggle tracks (also issue #157).
* `prepare-refseqs.pl` now by default uses a **more scalable directory**
** structure for storing sequences**. This fixes problems some users
were experiencing with large numbers of reference sequences
(issue #139).
* `ucsc-to-json.pl` now supports a `--primaryName` option allowing
the users to **alter which UCSC data field is displayed by JBrowse as**
** the primary name** of the features in a track. Also,
`ucsc-to-json.pl` now treats as indexable names all UCSC data
columns called "name", "alias", or "id" followed by zero or more
digits. Thanks to Steffi Geisen for this suggestion.
* Fixed "Duplicate specification" warnings coming from
`flatfile-to-json.pl` and `remove-track.pl`.
* Fixed bugs in which both the first few and the last few bases of a
reference sequence were not displaying correctly in a DNA track.
