• hgTables: sped up bigBed identifier search by using name index so it doesn't time out on huge files like dbSnp155
• Improved the ability to restore symlinked files back into their wrangle or submit directories so they are not lost in cdwReallyRemoveDataset
• Added -tsv option to bigBedToBed to create a TSV-style header that can be used with tools that work with TSVs, such as python CVS/TSV reader and Pandas
• Optionally replacing links to Youtube with links to videos hosted on our website using SSI

• hgPhyloPlace: improvements for RSV, better config support for new species, support for reference not from db or hub

28 November 2023, v457

• Added (i) icons to hgLiftOver, to explain the various obscure options without so much text on the page. Note that this uses the new printInfoIcon(text) function, which we can use on many CGIs
• Try again: users can now query old NCBI transcripts, both by name and in hgvs coordinates, for hg38 only
• Fixed problems with RTS load where composite and supertrack children were stuck in positions set by previous RTS loads
• hgSearch now allows clicking the text to show/hide results instead of just the small button
• Made more improvements to tooltips: left click or contextmenu click closes tooltip, fix tooltip y positioning when it would normally be above the viewport, left justify the tooltip text
• Snp hgc pages now use mitochondrial codon table
• Fixed never-used multi-term searches that each resolves to a singlePos structure to show a range with each item highlighted
• Fixed problems with forcing bigBed filtering to pass items found with hgFind
• Parse of bigGenePred record now generates a somewhat useful error message rather than abort when bigGenePred is incorrectly specified as track type. This prevents a blank-screen failure and gives the user some hint as to what might be wrong
• Now using forceTwoBit by default, no more .nib files are needed, (the RR has .2bit now for all assemblies)

7 November 2023, v456

• Both exonNumber on and "mouseOver ${fieldName}" are now allowed in trackDb, this means that gene tracks now can have mouseovers
• hgFind items now always pass the bigBed filters and always are in pack when we're doing squishyPack. This fixed a bug where squishyPack search results are not highlighted and stay squished
• Track short labels that are displayed on the main page now correctly encode special characters like < and >
• Stopped checking for data accessibility on the assumption that the trackDb build already did that. Add a little side-effect up higher in the call chain. This should probably be somewhere else, but in fear of breaking something new, I'm just popping it up one link in the call chain
• Added chainDupFilter which addresses a problem in axtChain where duplicated blocks are not chained

17 October 2023, v455

• Initial commit of track decorators feature, which permits drawing blocks and glyphs over bed-like tracks
• Added link from child trackUi page back to parent track
• Table browser "data format" (="schema") page now points to bigBed file for knownGene track
• Modified HGVS searching code to query an additional table of old alignments, if available bedToBigBed now allows the input to be compressed
• Turned off and fixed logo calculations which were slowing down the browser
• Made a change to not seek on the input levels when calculating zoom if it's already at the beginning of the file
• hgTables - Made links work better to support http or https
• Increased timeout in https.c from 10 seconds to 90 seconds. Needed for C-language htmlPage Robots on https like hgNearTest and others

• Now avoiding a million stat() calls in hReplaceGbdb
• Existing tooltip function hui.c:printInfoIcon() now uses new mouseover code
• Additional fixups to multiple PCR results code
• Relaxed the constraint on sorting for bedToBigBed and bedGraphToBigWig

26 September 2023, v454

• Added the assembly name to hgc page titles
• Fixed ancient word break bug on bigBed extra fields with super long strings
• There is now a more descriptive error message when no regions are in the output of the Table Browser

• Made java utils configurable between http and https, and https is the default in preparation for turning on redirect to https everywhere
• Tweaked the scripts that run robots written in C that should use https, since htmlPage code can use https but does not support redirects at this time
• Fixed notification box setup code to account for udcTimeout messages being set up server-side instead of client-side
• Made track hub search indexes otto update
• Added trix snippet index updates to knownGene build process

• Fixed bug in length spec search, if the user entered a length search, like chrA:X+Y, we first need to add Y to X before checking if the start and were a mistakenly swapped position
• Fixed a problem reported by user security scan in which the too-liberal CSP Content Security Policy needed to be tightened up, and only whitelist specific libraries, not entire domains. Updated the CSP policy in python hgLib and hgLib3 too
• Fixed dead url to primer3 in hgPcr
• Small bugfix to kent-core github repo, a copy of the kent repo with just the MIT licenses code

25 July 2023, v451

• Ongoing painful work to port hgGeneGraph to python3
• Ongoing work on summary tracks and blat displays for Human Pangenome Reference Consortium alignments to hg38
• Added mechanism to pslMap to fix problems with mapping prot-prot via prot-na alignment by explicitly specifying the type of alignments. Specifying types of input PSLs adds new checking for unsupported combinations

• Continued work on squishy-pack display
• Fixed html problems with hgHubConnect where the alignment of columns to headers was wrong. Also improved the alignment of the search details section
• Fixed search bugs: encode hub track names with non [a-z] names, allow psuedo HGVS searches that resolve to a rough position (while eliciting a warn) to still resolve, don't show unencoded search strings when a search fails
• Minor changes to wording of duplicate track feature to now say "duplicate #N" instead of "copy #N"
• Fixed bug where hub URLs were getting truncated
• bigMaf is now supported for sequence logos, also added logoMaf to bigWig tag types in support of adding the setting to all popular hg* and mm* conservation tracks
• Longer descriptions now allowed in autoSql column names, separated by a pipe character. (Crossing fingers that no one has pipe characters already in their labels)
• pslMap now trims overlapping blocks that can happen when mapping protein to DNA alignments from BLAT translated alignments

2 May 2023, v447

• Users can now keep multiple isPCR results in one track rather than overwriting the custom track with each new hit
• Changed recommended track sets to merge into the current session instead of overwriting it
• Longer descriptions are now allowed in .as field labels, separated by | character
• hgTracks searches that go to only one place now correctly set their parent track visibilities on the url
• Added a new endpoint to API: /list/files?genome=someGenome to provide a list of download files for the specified genome. TBD: document this feature and add error catching
• Added format=text argument to the API /list/files endpoint to return plain text list of files rather than the standard API JSON
• Added a new "downloadUrl" trackDb statement which adds a download link to the trackUi page
• Improved code around browser "themes" (=user-selected CSS files) which are now more resilient to crashing if there are missing files
• Ongoing work on incorporating snake display in the chain and psl support (including big versions)
• Cleaned up logoMaf display so it scales to the existing window instead of by the viewing region
• The DNA retrieval tool would sometimes fail to color bases in exons appropriately if the transcript began outside the window of retrieved DNA. This is now fixed
• Details pages for Interact tracks could fail to load if the track was set to generate multi-region view links and the file for the track was using chromosome aliases instead of native names. Chromosome aliases are now handled properly in that situation
• All CGIs now support a secret argument for logging to the Apache error log. utils.js contains an asynchronous function to call the CGI that included it with this argument. Used currently for reporting our javascript run time back to the server. Chris
• Errors were not being caught when trying to load a hic track with a missing file. Those errors are now caught and reported appropriately
• Small improvements to bigGuessDb
• GBiC patch to fix mysql tables that are in a broken state on hgdownload, like GBIB
• Fixed a dump bug in the pipeline library module that could cause second pipeline calls in a process to fail under some circumstances

11 April 2023, v446

• Moved the download current track data button to blue bar menu under "Downloads" (#30865). Chris
• Added a little help box with link to new FAQ if hgTracks takes longer than x seconds (-> hg.conf) to load (#30591). Max
• Changed the way we load recommended track sets. We now overlay their contents, no longer obliterating the current session (#28525). Brian
• Added downloadUrl trackDb statement, to show link to GFF files for gene tracks above the docs page, so it cannot be missed anymore (#30904). Max
• Added support for chromAlias to the hubApi (#30544). Hiram
• Fixed up broken support for curated assemblies in the API (#30544). Hiram

• Fixed dbSnp pipeline for handling clinvar records that had multiple significances (#30617). Galt
• Restored color to the Short Match track, which was being drawn with an alpha of 0 (invisible) after the transparency changes (#30866). Jonathan
• Restored standard color parsing for 3-value colors in BED files, as 255,255,255 (white) was causing an error with full alpha added (the color 0xffffffff has the value -1, which is interpreted as an error instead of a valid color) (#30569). Jonathan
• Highlights should now appear in multi-region mode; they were being ignored due to an error in chromosome name handling (#30833). Jonathan
• In image and PDF output, highlights would be broken by vertical bars from the blue ruler lines in the background. The combination of the two is now handled in the same way as the web display, which looks better (#30833). Jonathan
• Made hubId's portable in newly created sessions by saving away the hubUrl's of attached hubs in the cart (#28525). Brian

• Continuous GenArk process improvements (#29545). Hiram

21 March 2023, v445

• Transparency settings added with the new ghostscript (version >= 9.52). Internal effects gain the ability to use alpha-valued colors in both images and PDF output. This supports highlight effects in things like vcfPhasedTrio tracks. This may be a breaking change for some mirrors with custom code modifications - any hard-coded rgbColor structures will need to be updated to include an alpha specification. (#30569)
• Changed the multiwig solution for logos to use the specified track color rather than hardcoded value (#30828). Brian
• Fixed bug where liftover was interpreting colons in bed names as position format (#30705). Chris

• Added a "track snapshot" button to hgTracks. Under hg.conf control (#30024). Chris
• Added "download file" links directly to the table browser "schema / data format" button for bigDataUrl tracks (#30491). Max
• We no longer provide links to EPS versions of the hgTracks and hgGenome images. This is in preparation for creating non-compliant EPS files to facilitate transparency effects in Browser images and PDF output (#30606). Jonathan
• Redraw barChart svgs on the client so the column widths can be wide enough for labels (#28439). Chris
• Prevent faceted barChart configuration when doing right-click config (#30102). Chris
• hubApi "track" argument can now be a comma sep list to return data from multiple tracks at once (#30024). Chris

• Ongoing work to optionally show snakes in chain and psl display (#30280). Brian
• Made track duplication to be on by default without hg.conf variable (#30586). Brian
• gff3ToGenePred updated to handle Ensembl feature types. Mark
• Fixed minor problems found with newer gcc compiler on Ubuntu 20, compiled on a vm. Galt
• Disabled parallel loading in hgCustom on hic and bigMaf tracks which are not thread safe (#26445). Brian
• Added support for clould URLS for mirrors. A URL resolver plugin functionality allows an external program to convert cloud URLs (s3:, gs: drs:) to http/https URLs (#30445). Mark

7 February 2023, v443

• Added support for curated hubs to hubApi
• Users can now get exon-exon-straddling primers from primer3 by following an outlink on hgGene
