 - added `-isProductive <gene_feature>` column to export
 - improvements of report and alleles description table for `findAlleles` command
 - removing of unused genes from result library in `findAlleles` command
-- 'findAlleles' now more resilient to case when most allele variants of donor differ from *00 alleles in a library

 - fixed AssertionError in `findAlleles` command with `--output-template` argument
+- fixed wrong behaviour with `inferMinRecordsPerConsensus == true` and cell level assembly
+- fixed `minRecordsPerConsensus` inference mechanism for new filtering features introduced in previous version (4.3.0)
