+# v0.13.3
+## Changes
+- Added support for parsing pb-CpG-tools files that have been compressed (i.e., `{prefix}.combined.bed.gz`) to save storage
+
 # v0.13.2
 ## Fixed
 - Modified the checker for `profile` and `segment` modes to allow for missing hap1 and hap2 BED files. This is most common when pb-CpG-tools is run on unphased datasets. A warning will be produced in the log if these files are missing, and haplotype-specific data will not be generated.
