+<h2>Oct. 31, 2025 &nbsp;&nbsp; New GENCODE &quot;knownGene&quot; V49 for human (hg38/hg19) and VM38
+for mouse (mm39)</h2>
+
+<p>
+We are happy to announce the new GENCODE gene annotation tracks, corresponding to
+<a href="https://www.ensembl.info/2025/09/02/ensembl-115-has-been-released/"
+target="_blank">Ensembl release 115</a>, along with GENCODE knownGene V49 for human
+(<a href="/cgi-bin/hgTrackUi?db=hg38&position=default&g=knownGene">hg38/GRCh38</a>
+and
+<a href="/cgi-bin/hgTrackUi?db=hg19&position=default&g=knownGene">hg19/GRCh37</a>)
+and GENCODE knownGene VM38 for mouse
+(<a href="/cgi-bin/hgTrackUi?db=mm39&position=default&g=knownGene">mm39/GRCm39</a>).
+The GENCODE &quot;knownGene&quot; V49 and VM38 tracks were built using the UCSC knownGene pipeline and the
+GENCODE comprehensive gene set to generate high-quality manual annotations merged with
+evidence-based automated annotations. The GENCODE &quot;knownGene&quot; tracks are our default
+gene tracks, which have extensive associations to external sources. This allows for additional
+metadata on every item as well as external links. The track description pages contain options for
+configuring the display, such as showing non-coding genes, splice variants, and pseudogenes.</p>
+<p>
+Below is a summary of the contents found in each release. For more details, visit the

 <h2>Oct. 16, 2025 &nbsp;&nbsp; SpliceAI Wildtype tracks for hg38</h2>
 <p>
 We are pleased to announce the release of the
 <a href="/cgi-bin/hgTrackUi?db=hg38&position=default&g=spliceAIWt"
         target="_blank">SpliceAI Wildtype tracks</a> for hg38, available in the
 <a href="/cgi-bin/hgTrackUi?db=hg38&position=default&g=spliceImpactSuper"
         target="_blank">Splicing Impact superTrack</a>.
 These tracks show the scores for the genome sequence itself, without variants, from predicted
 splice donor (5&apos; intron boundaries) and splice acceptor (3&apos; intron boundaries) sites. Predictions
 are strand-specific, with separate subtracks for the plus and minus strands.
 <ul>
   <li><b>SpliceAI Acceptor Plus</b> &ndash; Splice acceptor sites, plus strand
   <li><b>SpliceAI Acceptor Minus</b> &ndash; Splice acceptor sites, minus strand 
   <li><b>SpliceAI Donor Plus</b> &ndash; Splice donor sites, plus strand
