@@ -3,6 +3,7 @@ RSEM v1.3.0
 - Added Prior-Enhanced RSEM (pRSEM) as a submodule
 - Introduced `--strandedness <none|forward|reverse>` option, `--strand-specific` and `--forward-prob` are deprecated (but still supported)
 - Revised documentation for `rsem-plot-model`, maked it clear that in alignment statistics, isoform-level (instead of genome-level) multi-mapping reads are shown
+- Significantly improved the output information of `rsem-sam-validator`: if indels/clippings/skips are detected in alignments or alignments exceed transcript boundaries, `rsem-sam-validator` will report them instead of telling you the input is valid
 - Updated the warning message to ask users to make sure that they align their reads agains a set of transcripts instead of genome when RSEM finds less sequences in the BAM file than RSEM's indices
