-## [unreleased]
+## [v2.4.0]
 ### Added
 - IGV configuration for the EPI2ME App includes the output VCF files.
 ### Changed
 - Emit indexes for the input reference, when generated by the workflow.
 - Links to the reference genomes in the README now point to `bgzip`-compressed fasta files.
 - Updated `modkit` to v0.3.3.
+- Reconciled workflow with wf-template v5.2.5
 ### Fixed
 - `ERROR ~ No such variable: colors` when the workflow cannot find the reference file.
 - Incorrect bin size unit in QDNAseq wrapper script help text (@HudoGriz, #209).
