- updated to Gencode v49 (was previously on v47)
- added a new optional visualization track called
"genes used for precomputed scores". It shows the Gencode v24 transcript models originally used by the SpliceAI authors to generate the precomputed SpliceAI score tables available from Illumina. This track can help explain some of the differences in scores between SpliceAI-lookup and these precomputed tables.
