 This is a hotfix release. It fixes the following issues:
 
-- This releases fixes a concurrency issue with pVACapi/pVACviz that would occurr when
-  users would try to visualize multiple files at the same time
+- IEDB will output a warning if an epitope contains only amino acid symbols
+  that could also be nucleotides. This would cause an error during parsing of
+  the IEDB output files. This version updates the parser to ignore these
+  warnings.
+- We added some improvements to pVACapi regarding database file read
+  speeds and transaction handling. This version also starts enforcing a file
+  size limit (14MB) for result files. Larger files will no longer be
+  visualizable in pVACviz since they take too long to load.
