+## 1.1.0
+* Added option to analyse long read data
+* Fixed bug that added 1 to total fragment length, this will slightly increase the fpbm_br and fpbm_nbr values 
+* added option to add header line to output
+
 ## 1.0.0
 * First release to calculate TA repeats FPBM values using samtools bedcoverage data
