+<h2>Oct. 23, 2020 &nbsp;&nbsp; The new GRCm39 Mouse Genome Browser is here</h2>
+<p>
+We are pleased to announce the release of a new mouse assembly, mm39, which corresponds to the
+GRCm39 assembly released by the <a href="https://www.ncbi.nlm.nih.gov/grc/mouse"
+target="_blank">Genome Reference Consortium</a> (GRC). Starting with this release, the UCSC Genome
+Browser version numbers for mouse assemblies will match those of the GRC to minimize version
+confusion. Hence, the GRCm39 assembly is referred to as mm39 in Genome Browser datasets and
+documentation.</p>
+<h3>About the assembly (mm39):</h3>
+<ul>
+  <li>
+    UCSC Genome Browser assembly ID: mm39</li>
+  <li>
+    Sequencing/Assembly provider ID: Genome Reference Consortium Mouse Build 39 (GCA_000001635.9)
+    GRCm39<li>
+  <li>
+    Assembly date: Jun. 2020</li>
+  <li>
+    Accession ID: GCA_000001635.9</li>
+  <li>
+    NCBI Genome ID: <a href="https://www.ncbi.nlm.nih.gov/genome/52" target="_blank">52</a>
+    (Mus musculus)</li>
+  <li>
+    NCBI Assembly ID: <a href="https://www.ncbi.nlm.nih.gov/assembly/7358741"
+    target="_blank">7358741</a></li>
+  <li>
+    NCBI BioProject ID: <a href="https://www.ncbi.nlm.nih.gov/bioproject/20689"
+    target="_blank">20689</a></li>
+</ul>
+<p>
+For more information about the files included in the GRCm39 GenBank submission, see the
+<a href="https://ftp.ncbi.nlm.nih.gov/genomes/all/GCA/000/001/635/GCA_000001635.9_GRCm39/README.txt"
+target="_blank">GRCm39 README</a>. The GRCm39 GenBank record provides a detailed array of
+<a href="https://www.ncbi.nlm.nih.gov/assembly/GCF_000001635.27/" target="_blank">statistics about
+this assembly</a>. Bulk downloads of the sequence and annotation data may be obtained from the
+Genome Browser <a href="ftp://hgdownload.soe.ucsc.edu/goldenPath/mm39/">FTP server</a> or
+the <a href="http://hgdownload.soe.ucsc.edu/downloads.html#mouse" target="_blank">Downloads
+page</a>. The annotation tracks for this browser were generated by UCSC and collaborators
+worldwide.</p>
+<p>
+We would like to thank the GRC and NCBI for creating this new mouse assembly. We would also like to
+thank Hiram Clawson and Jairo Navarro for the development and release of the mm39 genome browser.

 <h2>Oct. 21, 2020 &nbsp;&nbsp; October 21st release for SARS-CoV-2 genome browser</h2>
 <p>
 We are pleased to announce our fourth data release for the <a href="/cgi-bin/hgTracks?db=wuhCor1" 
 target="_blank">coronavirus genome browser</a>. (See also our <a 
 href="#040320">first</a>, <a href="#050420">second</a>, and <a href="#080720">third</a> 
 releases)</p>
 <p>
 In line with our previous releases, these tracks include diverse data such as gene 
 models, immunology, pathogenicity, and conservation. We would also like to bring 
 attention to our <a href="#092520">recently released</a> COVID-19 GWAS 
 tracks for the <a href="/cgi-bin/hgTrackUi?db=hg19&g=covidHgiGwas&position=lastDbPos" 
 target="_blank">GRCh37/hg19</a> and <a
