v479

Code changes:

• Added support for DropBox for hubs and custom tracks using byteranges (#35342). Galt
• Added "view conversions" link to hgLiftOver output page to display conversions as html (#20666). Max
• hgSearch now uses chromAlias (#34437). Chris
• First version of a positional heatmap track display that uses several extra fields in a bigBed. This is similar to the existing microarray track type, but should be more flexible (and supports multiple heatmaps in the same track)(#31812). Jonathan
• hubCheck now checks that subtracks have the same group setting as their parent to enforce implicit group correctness when the group setting is not set at the right level (#35078). Chris
• Added the db parameter to async hgTracks image updates to band-aid the multiple tabs with different genomes but same hgsid confusion (#35199). Chris
• hubApi can detect if the genome argument is an assembly hub (#34627). Chris
• hubApi getData endpoint can detect if requested tracks are in a track hub and retrieve them without explicitly setting hubUrl argument (#34627). Chris
• Increased the number of split tables allowed (#35253). Brian
• Improvements to wuhCor1 big tree build process. Angie.

Data changes:

• Updating GenArk build procedure for NCBI RefSeq track to get proper GeneID values into the bigGenePred file and subsequent proper out links to NCBI gene resources (#32704). Hiram
• Continuous GenArk updates and liftOver file generation (#29545). Hiram
