+RSEM v1.1.21
+
+- Removed optional field "Z0:A:!" in the BAM outputs
+- Added --no-fractional-weight option to rsem-bam2wig, if the BAM file is not generated by RSEM, this option is recommended to be set
+- Fixed a bug for generating transcript level wiggle files using 'rsem-plot-transcript-wiggles'

+
+RSEM v1.1.20
+
+- Added an option to set the temporary folder name
+- Removed sample_name.sam.gz. Instead, RSEM uses samtools to convert bowtie outputted SAM file into a BAM file under the temporary folder
+- RSEM generated BAM files now contains all alignment lines produced by bowtie or user-specified aligners, including unalignable reads. Please note that for paired-end reads, if one mate has alignments but the other does not, RSEM will mark the alignable mate as "unmappable" (flag bit 0x4) and append an optional field "Z0:A:!"

+- Added some user-friendly error messages
+- Added program 'rsem-sam-validator', users can use this program to check if RSEM can process their SAM/BAM files
+- Modified 'convert-sam-for-rsem' so that this program will convert users' SAM/BAM files into acceptable BAM files for RSEM
