==5 November 2024, v473 ==
 
* Fix density mode for vcfTabix
* Fix problem with hubUrl being trashed if Genark hub was specified as db
* Ongoing work on behaving rationally when certain limits are exceeded in hgTracks
* Primer3 outlink from hgGene now gets +-200bp flanking seq around the first and last exon to design primers around the exons
* Fix freeType and Postscript handling to deal with UTF-8 encoded strings
* Adapting the tutorial reminder to say where users can find the tutorial if they click it away now
* Right click - move to top respects the ruler track
* Click OK when "enter" key is pressed on trackUi dialog box
* Now we just filter all the types, like BLATs guess, which makes them consistent and correct, the same as the default behavior it always had
* The configuration page for some track types can include a selector to change the track color, but the selectors for subtracks of a composite were all being placed in the configuration block of the first subtrack. They are now distributed among the subtracks
* Don't show download link to big* files on the table browser for non-distribution tracks
* Fixed jQuery upgrade bugs: group drag and drop of tracks, drop-down checklist position, checkboxes marked as change during a form submit
* Disable the "download track data in window" option on GBiBs since they don't have an API available
 
==15 October 2024, v472 ==
 
* Added new options to the right-click menu: hide all others, move to top, move to bottom
* Upgraded jQuery and jQuery-ui to the latest versions
* Force all tracks into coverage mode if 32K image size would otherwise be exceeded
* Users can now specify their parallel load timeout value
* Added (i) icons to table browser to better indicate you can mouseover for help text
* The hgLiftOver CGI and the command-line liftOver tool now include an option to keep a copy of the positions from the input file in the lifted output (for formats like BED, genePred, and others that include an item name field or something similar). This should help keep track of which items get mapped where for some users
* Various improvements to both the hgGateway search and new GenArk search
* Amino acid display now only shows up at base level
* Made the two reset genome browser links in the menu the same
* Performance improvements for Hi-C tracks (and anything else that uses fakeCurl) - we now do a better job of re-using an existing udc handle for a series of requests on the same file. This should also fix some issues associated with having "too many file handles" open when viewing multiple Hi-C files at once
* The option to change some track draw colors is now available on their hgTrackUi page as well as the pop-up configure box in the main browser, and that option remembers what color was previously chosen for that track
 
==24 September 2024, v471 ==
 
* Changed track control labels so they word-wrap
* For assembly hubs, strip hub_ prefix in table browser fasta output
* Made hgTrackUi schema links visible in the window, even when a subtrack config is open. Limit the subtrack config to the size of the window, but make it scrollable
* Improved genbank search by reducing number of MySQL commands
* Allow configuration of bigBed filters on bigGenePred tracks
* Fixed a few instances of '.' in table names not being allowed/anticipated
 
==9 September 2024, v470 ==
 
* Basic support for multiple decorators on one track is in place; documentation (and UI review) pending
* Added checkbox to hgTrackUi of ruler track to make amino acid display more on by default
* If a track hub has a track specified with a group that is not defined, put the track in the generic group for that hub, not in "other"
* Allow bigInteract tracks' endsVisible to be set via trackDb in addition to hgTrackUi
* Decorator UI should now respect trackDb settings for blockMode and glyphMode
* Fixed up mouseOver wiggle track when a track in wiggle mode switches to not wiggle mode, do not display the mouseOver
* Fixed a bug where an automatic switch to density mode was not setting the track type to wig
* Fixed a problem in the bigBed library with summary levels failing on very large chromosomes
* Fixed an issue where the newly-introduced fakeCurl library had a namespace collision with libcurl, which broke remote halSnake tracks
* Support added for multiple filterBy sets on the same page of HTML
 
==13 August 2024, v469 ==
 
* Added a configure page option for controlling whether hgc clicks open in pop-ups or not
* Made knownGene handle like regular tracks by hgSearch, moved HGNC and MANE search results ahead of knownGene in priority
* Hi-C tracks now have support for version 9 of the hic file format (the current latest). Basic support for other normalization modes is also included, but we recommend you add any normalization to all resolutions in the file instead of only selected ones
* Standardized the font size of our dialog windows (rec. track sets, multi-region, etc)
* Changed chroms to chromAuthority names in hgBlat and hgPcr
* Track heights now capped at 31,000px
* Print BLAT version on hgPcr form since ask for it
* Made priority optional in groups.txt. for the hub groups feature. Also actually sort by priority if specified
* Fixed defaultIsClosed flag on the hub groups feature and changed it to sort groups by name without regard to case

==23 July 2024, v468 ==
 
* Pop-up hgc pages can now be exited by clicking outside the box
* Extended DNA case/color output now works for track hubs
* Increased the font size for jquery dialogs
* Force underlines under lowercase g in modern web browsers that are too smart for biology
* PSL custom track default settings now shows mismatches
* Removed the requirement for defaultIsClosed and Priority from the hub groups setting
* In some situations, the browser mouseover text was reporting the same exon number for multiple different exons in a track. This is now fixed, and the mouseover text for each exon should accurately reflect its index
 
==2 July 2024, v467 ==
 
* Removed some of the text below the hgTracks image
* Made some tooltips have longer delays than others and removed some of the less helpful tooltips
* hgc page for BAM: removed the "English" CIGAR text and added a new legend for normal cigar string

* Removed the click & drag to scroll tooltip from hgTracks image
* Fixed native assemblies not being selectable in hgGateway autocomplete
* Search results in hgTables now bold properly
* Unify the different color pickers (drag select highlights, track item highlights and track item colors) into hui.js. Ensure the text box and palette selector work
* Merged blatHuge implementation. This adds a gfServer and blat that search genomes greater than 4 gigbases

= 2023 =
 
== 19 December 2023, v458 ==
 
* Custom track parsing: don't remove custom track files when there is an error
* Add the ability to simulate a custom track load error using ctTest=1 on the URL
* Additional tooltip improvements: make the tooltips go away when mouse leaves the web browser window or enters an input box or right-click. Improved the tooltip Y position to go lower or higher depending on where the mouse enters from. Made the font size of the tooltips be a configurable option
* Added right-click option to enter exon position for genePred tracks
* Made enter key submit forms in dialog boxes
* Made ref seq historical track open when HGVS term hit an outdated transcript
* Hide children of superTracks when loading RTSs
* YPs (chrM genes) got dropped from Refseq curated track, changing doNcbiRefSeq to put them back
* Added utility (fixTrackDb) to update trackDb to what files are actually on the system
* Fixed problem in tdbQuery with overrides not being addressed properly, this came up with the RefSeq composite edits by Lou
* Fixed problem in hgNear building bad links into hgGene on the description field
* 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
* Better adherence to W3C html coding standards in static html pages
* 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
* Made a change to no longer check to see if a track's bigDataUrl files or tables are available at hgTracks run time, just trust trackDb
* 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
* Download track data in window improvements, disabled multi/math wig tracks because those are not supported in the api yet. Chris
* 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
* hgPhyloPlace: added linkouts to MicrobeTrace (for subtrees up to 500 sequences)
 
== 5 September 2023, v453 ==
 
* Allow hgTracks tutorial to automatically start when a special variable is on the URL
* First version of liftOver-on-the-fly to liftOver annotations between assemblies in 'real' time
* Added VCV outlink to clinvar page
* Warnings now show up properly in hgSearch
* More fixes to multiple PCR results code
* Fixed pgSnp items not scaling correctly when item is off the left side of the window
* 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 ==
 
* Changed track list to 90% of screen width on hgTracks
* Fixed addition bugs on hgGeneGraph for Python3 now that Python2 has been stopped
* Fixed trash icon bug that happens when one clicks a lot of trash icons very quickly and a race condition on ctfile changes occurs
* Added -bed option to bigBedToBed, for cases where people have thousands of regions to export, not just one
* Changed the default maxItems from 250 to 10,000
* Fixed javascript bug that was preventing the warnSeconds and interactive tutorial popups
* Fixed old bug where html tags could show up in hgGatway

* 8 columns are now allowed instead of 6 in the tracks table under the track image on hgTracks, and also restricting the shortLabel width to 16 em (=characters)
* Added a new -bed option to bigBedToBed, also removing the -maxItems option as it never worked and is not used anywhere in our code
* cartReset now resets the entire localStorage. For now, this only resets the status of the "don't show this again buttons"
* Added a note about _alt _fix and _hap to hgTracks
* Fixed up notification box to show multiple different notifications, make notifications hideable/showeable via localStorage
* Added silent Google reCAPTCHA v3 to the user suggestion form
* Fixed a few places where we did not encode user inputs
* Enhanced initial geoIpToCountry command from Galt to allow processing all IP addresses in all apache logs archived here. Hiram
* Made a utility that uses our existing geoIp infrastructure to lookup the country code from an IP address (IPv4 or IPv6). We are using it to identify the UCSC Genome Browser usage even when Google Analytics is being blocked in some regions of the world
* 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
 
== 13 June 2023, v449 ==
 
* Added short sequence blat search to hgGateway search bar, which was already available on hgTracks
* Cart is now dumped to trash if the browser took too long to draw in order to review long-loading sessions

== 23 May 2023, v448 ==
 
* The API 'list' function is now available and documented
* 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 non-knownCanonical results not showing up in a knownGene search (#25078). Chris
* Turned on phyloP logo for 100 way on hgwdev, phyloP scores are shown as a sequence logo if zoomed in to near base mode. Brian
* Single position search coming from hgGateway now goes directly to hgTracks before drawing any html. Chris
* 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
* Fixed a bug in trackDb caching that I introduced when saving trackDb parsing errors in each tdb rather than crashing the whole browser (#30881). Brian
* Added download links for gene track GTF files in GenArk assemblies in description pages for tracks, soon to be obsolete by downloadUrl trackDb statement. Hiram
bigMafToMaf program has been updated to use significantly less memory, allowing large bigMaf files to be converted back to MAF (#28491). Mark
* Made kent-core repo with all MIT-licensed kent-code only see https://github.com/ucscGenomeBrowser/kent-core. Max
* Added a change list to trackDb, see https://genome-test.gi.ucsc.edu/goldenPath/help/trackDb/changes.html. Max
* 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 support for Genark genomes to the minuscule tool chromToUcsc (#30454). Max
* Fishing up snakes on bigPsl and chains (added some developer only dotplots). Brian
* Ongoing work on making Recommended Track Sets not trash custom tracks or highlights (#26404). Brian
* Added logos built on-the-fly using a wiggle and an associated MAF track. Brian
* Added support for Google Analytics 4. I am unable to use their new UI though, the new version is very hard to use (#30725). Max
* Added a 'vm' option to gbib's update script that can update the underlying operating system to the next version (#24254). Chris
* Tiny GBIC fix for the brand new Fedora 37 linux which we would have run into with all other linux distros soon (#30578). Max
* Various uniprot track updates (#30701). Max
* More work on the trackDb tableBrowser setting in the hubApi, including added tests. Chris
* Fixed table browser schema page when a non-assembly database table. Chris
* Added a few more domains to the https domain whitelist. Galt
* Fixed crash in chromAlias resolution in hgTracks (#30578). Max
 
== 28 February 2023, v444 ==
 
* Added two new right click options when clicking on a genePred track, zoom to codon and zoom to exon (#2724). Chris
* Added query strand and position as color and mouseover to BLAT results tracks (both bigPsl custom track and special BLAT output track), (#30578). Max
* 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

This page contains a list of major new software features found in the UCSC Genome Browser. The most recent features are always at the top of the page. A more detailed list can be found at https://genecats.gi.ucsc.edu/builds/versions-all/v<versionNumber>.html

2024

5 November 2024, v473

  • Fix density mode for vcfTabix
  • Fix problem with hubUrl being trashed if Genark hub was specified as db
  • Ongoing work on behaving rationally when certain limits are exceeded in hgTracks
  • Primer3 outlink from hgGene now gets +-200bp flanking seq around the first and last exon to design primers around the exons

  • Right click - move to top respects the ruler track
  • Click OK when "enter" key is pressed on trackUi dialog box
  • Now we just filter all the types, like BLATs guess, which makes them consistent and correct, the same as the default behavior it always had
  • The configuration page for some track types can include a selector to change the track color, but the selectors for subtracks of a composite were all being placed in the configuration block of the first subtrack. They are now distributed among the subtracks
  • Don't show download link to big* files on the table browser for non-distribution tracks
  • Fixed jQuery upgrade bugs: group drag and drop of tracks, drop-down checklist position, checkboxes marked as change during a form submit
  • Disable the "download track data in window" option on GBiBs since they don't have an API available

  • 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

  • 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

  • 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
