+<h2>Apr. 01, 2021 &nbsp;&nbsp; Update to sno/miRNA track for human (hg19)</h2>
+<p>
+We are happy to announce an update to the sno/miRNA track for human assembly hg19. With this update,
+the miRBase database was updated to version 20. The four different types of RNA and their counts in
+the human genome are listed below.
+</p>
+<ul>
+  <li>
+  C/D box small nucleolar RNAs (C/D box snoRNAs): 269</li>
+  <li>
+  H/ACA box snoRNAs: 112</li>
+  <li>
+  precursor forms of microRNAs (pre-miRNAs): 1871</li>
+  <li>
+  small Cajal body-specific RNAs (scaRNAs): 21</li>
+</ul>
+<p>
+We would like to thank Hiram Clawson and Jairo Navarro for the creation and release of this update.

 <h2>Mar. 30, 2021 &nbsp;&nbsp; Updated Chain/Net tracks for Mouse (mm39/GRCm39)</h2>
 <p>We are pleased to announce the update to the <a target="_blank"
 href="../../cgi-bin/hgTrackUi?db=mm39&g=mm39ChainNet&position=default">Chain/Net</a> tracks
 for the recently released mouse assembly
 <a target="_blank" href="../../cgi-bin/hgTracks?db=mm39" >mm39/GRCm39</a>.
 The chain track shows alignments of the mouse assembly to 29 other
 organisms using a gap scoring system that allows longer gaps than traditional affine gap scoring
 systems. The net track shows the best mouse/other chain for every part of the other genome.</p><br>
