+Notable changes to minimap2:
 
  * New feature: added the `splice:sr` preset for short RNA-seq read alignment.
    Users may use `-j` to specify known gene annotation to improve spliced
-   alignment close to the ends of reads. Also added `--write-junc` and
+   alignment close to the ends of short reads. Also added `--write-junc` and
    `--pass1` for 2-pass short-read RNA-seq alignment.
 
  * Experimental feature: read splice scores from a file specified by `--spsc`

+Minimap2 now supports short/long genomic/RNA-seq read alignment along with
+contig alignment and all-vs-all read overlapping. It produces identical genomic
+long-read or contig alignment to v2.27. Short genomic read alignment and the
+mapping quality of long RNA-seq read alignment may slightly differ in very rare
