version 2.48.0 - 2023/08/31

  • Root sequence data may be inlined in the main dataset JSON (Auspice PR #1688 and Augur PR #1295).

  • Bugfix: Fixes a crash when a dataset without the entropy panel attempted to change colorings. (#1691)

version 2.47.0 - 2023/08/21

  • Entropy panel now supports more complex genome architectures and has improved styling. The JSON schema has been extended to allow segmented CDSs, which allows us to represent CDSs such as those which wrap the origin (common in HepB), and those with ribosomal slippage (nCoV, EBOV). The visual representation of CDSs now better conveys overlapping CDSs, both in the lower “nav” axis where CDSs are stacked on top of each other and in the upper “main” axis where we now view the translations for each CDS individually. A number of small genotype-related bugs have also been fixed and the internal representation of the genome streamlined. For full details please see #1684, and the schema changes are detailed in augur PR #1281.

  • Fixed a bug where metadata TSV download was sometimes empty or incomplete, described in issue #1411. (PR #1681)

    • Continuous colourings can provide a scale, which we interpolate between to get the colour scheme

    • Custom legend data can be provided, including display text and, for continuous variables, bounds to map legend entries to values in the data.

    • Displayed legend entires may be restricted by specifying them in the dataset JSON.

    • See PR 1340 for more.

  • Filtering via the sidebar UI now returns options which match each of the space-separated queries, rather than requiring an exact match of the query. See PR 1344 for more.

  • Legend text now takes the maximum available space. See PR 1328 for more.

version 2.25.1 - 2021/04/07

  • Bugfix for cases where certain interactions with scatterplot variables would cause auspice to crash. See PR 1332 for more.

version 2.25.0 - 2021/03/31

  • Scatterplots are now available as a tree layout. These allow graphs to be created between any two continuous traits (colourings), similar to the “clock” layout but with user-definable variables Branches and regression lines can be toggled on/off, and nodes which do not define valid values for both variables will be hidden. Note that the regression line is calculated with a free intercept, which differs from the clock view where we force it to pass through the root. See PR 1310 and PR 1326 for more.

  • Datasets may now define “data provenance” which will be rendered in the byline. See PR 1313 for more.

  • Names within the filtering UI now use the metadata-provided title, which is clearer. See PR 1327 for more.

  • Frequency rounding is improved for small values. See PR 1301 for more.

  • Node traits may define a URL which will result in the value being displayed as a link. See PR 1308 for more.

  • A bug was fixed which caused some datasets to crash auspice when metadata files were dragged on. See PR 1319 for more.

version 2.24.1 - 2021/03/19

  • [bugfix] Fixes a bug introduced in v2.24.0 where certain datasets wouldn’t load

version 2.24.0 - 2021/03/17

  • Frequencies are no longer normalized when the data is lacking. See PR 1278 for more.

  • Fixed a stack size bug, which mainly affected the TB dataset on certain browsers. See PR 1293 for more.

  • Root-to-tip mutations are now displayed in the tip-clicked info box. See PR 1280 for more.

  • Datasets may now define the default language. See PR 1303 for more.

  • Polish language added. See PR 1288 for more.

  • Tips in the tree should no longer be obscured behind the legend. See PR 1302 for more.

  • Dates BCE are now correctly displayed in the phylogeny axis. See PR 1297 for more.

version 2.23.0 - 2021/01/28

  • [feature] Implement genotype filtering. The sidebar, typing-based filter UI now includes genotypes (for datasets which define mutations on branches). See PR 1265 for more.

  • [bugfix] Update how we generate the bundle hashes as the fix introduced in v2.22.2 was insufficient. See PR 1272 for more.

version 2.22.2 - 2021/01/14

  • [bugfix] Updated how we generate hashes for the transpiled, chunked client bundles. This prevents subtle bugs where bundles could have the same hash, but different contents, and thus stale (browser cached) chunks may be used in certain situations. This bug most probably arose in v2.22.0, so please update to this version if possible! See PR 1263 for more.

version 2.22.1 - 2021/01/13

  • Updated package-lock JSON file

version 2.22.0 - 2021/01/11

  • The address Auspice uses to fetch map tiles, including the API token, has been updated and will now only work for local installs of auspice. For help on how to specify your own address, which lets you specify custom map tile sets, see the Auspice docs. See PR 1261 for more.

  • Animation controls have moved and are now in the sidebar, underneath the date-slider. See PR 1262 for more.

  • The footer has been updated to streamline the Nextstrain accreditation and now displays “Powered by Nextstrain”. If you are serving your own version of auspice we ask for this accreditation to remain be maintained, in keeping with the spirit of scientific citations. Please also remember that customised version of auspice must make their source code available, as per Auspice’s licence. See PR 1260 for more.

version 2.21.0 - 2021/01/06

Improved Functionality

  • Tree rendering and zooming has been improved.

    • A new Zoom to Selected button has been added which allows you to zoom the tree to the clade containing the currently selected tips (PR 1257).

    • Branches ancestral to the common ancestor of the currently selected tips are now correctly rendered (PR 1248).

  • The Download Data functionality has been improved to export data reflecting the currently viewed subset of data. Additionally we export annotated Nexus trees which can be parsed by FigTree. See PR 1245 for more.

  • The drag & drop metadata functionality has been improved to facilitate easier filtering, custom locations and colours. See PR 1244 or these docs for more.

  • Tip labels are now user-selectable via a drop-down in the sidebar. See PR 1246 for more.

  • Legend values now dynamically update to reflect those in the current view. See PR 1250 for more.

Other Changes

  • Italian translation added. See PR 1256.

  • Amino acid labels are only shown on branches leading to big clades. See PR 1249 for more.

  • Colour scale generation has been refactored and a (rare) bug fixed where color-bys which defined a scale in the JSON could cause tips with no trait value set to have a colour rather than a shade of grey. See PR 1237.

  • Warnings added to documentation pages which are imported into Nextstrain’s (main) RTD project. See PR 1234.

  • Disabled a smoke-test which was stochastically failing on GitHub Actions (but which worked locally). See PR 1258 for more.

version 2.20.1 - 2020/11/19

  • Small bugfixes and performance improvements relating to to the features introduced in 2.20.0

version 2.20.0 - 2020/11/18

See PR 1200.

  • Improve how we space temporal grid lines (phylogeny & frequencies panels). See PR 1229.

  • Fix a bug in how we detected HTTP status codes. See PR 1226.

  • Auspice documentation is now switched to the Read The Docs platform, and available at Redirects have been added for the old GitHub pages site, and can be found in the redirect-documentation branch. See PR 1220.

version 2.19.0 - 2020/10/07

  • The auspice client now makes a request for the root-sequence JSON, which allows colouring of the tree by genotypes where there are no mutations. See PR 1197.

  • polyfill Promise to avoid crashes in old browsers. See PR 1217.

version 2.18.4 - 2020/09/28

version 2.18.3 - 2020/09/22

  • Add between-paragraph padding for text rendering in (non-mobile) narratives.

version 2.18.0 - 2020/08/03

  • Parse narratives client side. See PR 1193 and PR 1172. This shifts the default client behavior to request a narrative in markdown format and parse it client-side. The server still retains the ability to parse narratives server-side and return narratives in JSON format, so there are no breaking changes.

  • Narratives can now contain multiple datasets. See PR 1193, PR 1176 and PR 1164. Narrative slides may now define their own unique datasets, with datasets preemptively fetched and cached to improve performance. Invalid datasets will show an error notification and fallback to the dataset defined by the frontmatter of the narrative.

  • (Bugfix) Zooming in the entropy panel by using shift/option + mouseWheel now appropriately updates the URL query. See PR 1188

  • (Bugfix) The animation occuring when zooming the phylogeny is now restored. See PR 1192

  • A bug was fixed where loading a tree zoomed to a clade would prevent zooming out. See PR 1156.

  • A bug was fixed where numeric branch labels couldn’t be used as URL queries. See PR 1157.

  • The list of allowed nodejs versions was expanded. See PR 1166.

version 2.16.0 - 2020/05/29


  • Drastically improve how we bundle our JavaScript to improve loading times and allow more stable caching. See PR 1126 for more.

  • Improvement in code which decides which footers to show. See PR 1118 for more.

  • Documentation improvements – see PR 1127 for more.

  • Fix an error in map positioning in some narrative slides. See PR 958 for more.

  • Rename test snapshots for Windows support. See PR 1122 for more.

  • Certain errors preventing the server from running are now caught & helpful messages printed. See PR 1140 for more.

  • Frequencies added to narrative

  • block in focus is part of the URL query, and can be reloaded via the URL

Second Tree / Tanglegram

  • Second tree can be loaded via a URL (e.g. ?tt=na). Sidebar dropdown currently disabled.

  • In this mode, trees are forced to be rectangular, and the map & frequencies are not displayed.

  • Tanglegram exists, but no untangling (yet)

  • Bugs still exist (which is why the sidebar has been disabled)


  • All JSONs (incl. frequencies, narrative) are loaded within a single Promise & dispatch

    • Frequency text box is more readable

    • Frequency normalisation has been removed

version 1.14.1 - 2018/02/27

  • Style tip stroke separately from branch stroke (node.stroke replaced with node.branchStroke & node.tipStroke)

version 1.14.0 - 2018/02/27


  • Strain search (using awesomplete). This highlights the path to a single tip and increases the tip radius. Strain is stored in the URL query (s=...) and can be restored via URL. Selected strain also appears in the info panel (top of screen).

  • Amino acid branch labels (for every tree) as well as clade labels if specified by the clade_annotation attribute. AA labels are shown where the descendent visible tips account for more than 5% of the total visible tips (same as nextflu). Clade labels are always displayed.

  • Default geneotype gene is now HA1 if available (previously nucleotide).

  • ColorBy ordering (sidebar dropdown) is now ordered (via an array in globals.js)


  • The JSON processing on initial load has been shifted from the reducers to a single action - fewer dispatches, fewer potential bugs, faster code.

  • Frequencies are initialised in a single action (previously 2).

  • tip-frequencies are now downloaded via

  • Frequency actions are not dispatched unless the frequency panel is loaded.

version 1.13.2 - 2018/02/26

  • Improve consistency of panel controls

  • Show unassigned in tree legend (if applicable)

version 1.13.1 - 2018/02/26

  • Tree button “reset layout” now at top right

version 1.13.0 - 2018/02/26


  • Frequencies are now displayed via a stream graph panel - see PR 497. These require the fetching of a separate tip-frequencies JSON, and must be specified in the panels array of the meta.JSON.

  • “Panels To Display” toggles in the sidebar allow customisation of the display, and this is reflected in the URL.

  • The + - buttons in the tree have been replaced by a “reset tree” button. This resets the bounds to the entire tree & completely re-renders the tree (filters are maintained). Pan behaviour is unchanged.


  • React-PhyloTree interface is completely rewritten to use phylotree.change() - see PR 501 for the API. The new interface is both easier to understand and quicker.

  • changePageQuery (used for changing narrative blocks) is now a single action

  • Ongoing narrative work (still disabled).

  • React sidebar has been removed (no UI changes).

version 1.12.0 - 2018/02/14


  • Vaccine strains are shown at their use date (in temporal trees), with dotted lines connecting them to their tips (representing collection date) (PR 498)


  • updateGeometryFade uses counters to know when transitions are finished rather than setTimeout

version 1.11.0 - 2018/02/05


  • Vaccine strains are now displayed if they are specified in metaJSON.vaccine_choices (PR 490)


  • Tree components and PhyloTree have been reorganized (in src/components/tree) and the syntax improved (PR 493)

  • Upgraded to React 16, as well as upgrading redux & react-svg-pan-zoom (PR 494)

version 1.10.0 - 2018/02/05


  • Local Branching Index (LBI) coloring can be calculated in Auspice (code identical to nextflu) if specified in color_options (meta JSON) (PR 491)


  • script updated to no longer download sequences & entropy JSONs

  • action logging middleware available for debugging / development

version 1.9.0 - 2018/01/30


  • Animations can now loop! This is selected via a toggle in the sidebar.

  • While animating, the URL displays information which defines the animation (bounds, looping, cumulative, speed). This allows the animation to start automatically by linking to this URL.

  • The code for the animation (i.e. the setInterval code) has been moved out of Map and into a separate AnimationController component.

  • Animation is stopped & started by examining redux state, rather than with imperative controls.


  • The narrative machinery has been moved forward, but this functionality is still disabled and not present in production code.

  • The (rather expensive) calendarToNumeric calculations have become part of state.controls so that components no longer have to calculate them from the string form.

version 1.8.0 - 2018/01/18

entropy calculated via tree

  • The entropy panel data is now computed within Auspice by examining mutations throughout the tree, and is throttled to improve speed under load.

  • Both entropy and number of mutations are available via a toggle similar to AA/NT

  • This results in entropy.JSON no longer being fetched.

  • The entropy data is stored in redux state rather than the react component

  • The D3 code has been reorganised

  • Note that the entropy values are slightly different to those exported by Augur in some situations - see

genotype calculated via tree

  • This results in sequences.JSON no longer being fetched.

  • Augur was updated to export annotations which are needed for entropy gene display.

middleware / react router

  • All changes to the URL are now performed via middleware rather than side-effects within the action definition.

  • React router has been removed

  • Browser back/forward is detected via window.addEventListener('popstate', this.onURLChanged) which also fires on initial page load.

  • Pages are selected via the <PageSelect> component.


  • The number of proteins displayed while hovering over a branch has been limited to 7 (issue #484)

  • The presence of author data is checked before display (issue #488)

  • This changelog has been created and a step in the releaseNewVersion script added to prepend the version number upon release.

version 1.7.2 - 2018/1/4

Narrative / situational report

  • Functionality has been added, but is currently disabled via a flag in globals.js.

  • This is currently rendered in a right-hand sidebar. This feature is not yet complete.

URL queries

  • The following state has been added to the URL query:

    • filters, e.g. f_authors=Tong_et_al,Capobianchi_et_al&f_division=kerouane

    • genotype URLs (these were previously set as the URL but not parsed)

    • panel layout (grid/full)

  • A number of bugs regarding URL query state parsing (esp with genotype colorBys) have been fixed.

version 1.7.1 - 2017/10/31

  • Added mumps acknowledgment
