Feb 5, 2023
- show Pangolin scores in addition to SpliceAI scores.
- update to Gencode v42 (was previously on v38)

June 2, 2021
- show RefSeq ids for the subset of Ensembl ENST ids (~30%) that have one or more matching RefSeq NM ids according to Ensembl. See issue #8 for details.
- update to Gencode v38 (was previously on v37)

April 11, 2021
- show gray background for non-coding transcripts
- switch to showing all non-coding transcripts. (Previously, transcripts with Gencode biotypes like lncRNA, processed_pseudogene, processed_transcript, retained_intron, and nonsense_mediated_decay were filtered out if they overlapped protein_coding transcripts). See issue #6 for details.
- update to Gencode v37 (was previously on v36)
