+RTG Core 3.8.3 (2017-08-02)
+---------------------------
+
+This release primarily includes bugfixes and minor improvements:
+
+* rocplot: (GUI) Improvements to graph zooming, to allow stepping back
+  to previous zoom levels as well as fully un-zooming.
+
+* rocplot: Improve the automatic curve naming heuristic to ignore
+  directory name suffixes like "-eval", ".vcfeval" etc, and similar
+  prefixes.
+
+* rocplot: Enable text antialiasing in GUI and PNG output.
+
+* vcfeval: More graceful handling of input VCFs containing REF values
+  that are not valid according to VCF specifications.
+
+* vcfmerge/vcfeval: Normalize the casing of nucleotides in REF/ALT,
+  which permits merging records where the REF/ALT differ in casing.
+
+* vcffilter: Graceful error handling of a new category of invalid
+  javascript expression.
+
+* vcfsubset: Don't complain when using --keep-filter/--remove-filter
+  flags with "PASS" and the VCF header doesn't contain a declaration for
+  that filter.
+
+* misc: Prevent a unit test failure when running on newer versions of
+  Ubuntu.
