JBrowse 1.15.3 has been released! This contains an bugfix introduced in 1.15.0 where typing a reference sequence name in the search bar did not navigate to it properly.
It also contains a cool feature where "ultra minimal configs" can be specified by simply specifying a track label and urlTemplate

For example, a directory containing indexed files like VCF, BAM, GFF3 tabix, and indexed FASTA can have a config simply like this in tracks.conf

```
[GENERAL]
refSeqs=volvox.fa.fai
[tracks.refseq]
urlTemplate=volvox.fa
[tracks.bam]
urlTemplate=volvox-sorted.bam
[tracks.cram]
urlTemplate=volvox-sorted.cram
[tracks.vcf]
urlTemplate=volvox.filtered.vcf.gz
[tracks.gff]
urlTemplate=volvox.sort.gff3.gz
[tracks.bed]
urlTemplate=volvox.sort.bed.gz
```

## Minor improvements

 * Add ability to automatically deduce the storeClass and trackType of files based on
   the file extension of urlTemplate. This allows very minimal configs where only
   track label and urlTemplate can be specified. (<a href="https://github.com/gmod/jbrowse/pull/1189">issue #1189</a>, <a href="https://github.com/cmdcolin">@cmdcolin</a>)
