incorporated mention of chimeric junction updates in Changes.md
+* Chimeric read reporting now requires that the chimeric read alignment score higher than the alternative non-chimeric alignment to the reference gneome. The Chimeric.out.junction file now includes the scores of the chimeric alignments and non-chimeric alternative alignments, in addition to the PEmerged bool attribute. (bhaas, Aug 2019)
* Fixed the problem with ALT=* in STAR-WASP.
* Implemented extras/scripts/soloBasicCellFilter.awk script to perform basic filtering of the STARsolo count matrices.
