 ## [Unreleased]
 
+## [1.4.3] - 2025-01-18
+
 ### Fixed
 
 - Fixed `VariantPeptideIdentifier` that ORF ID was added before variant IDs.
 
+- Fixed `callVariant` that failed on small circRNA with a lot of variants at the step that creates the cleavage graph. #885
+
 ### Changed
 
 - Changed variant IDs for circRNAs to use backsplicing site instead of listing all exons/introns. #878
