Heroku Stack Upgrade: This release includes an update to the Heroku stack used in dash app deployment from Heroku-16 to Heroku-18. A stack is an operating system image that is typically based on an existing open-source Linux distribution (i.e. Ubuntu). The full overview of the Heroku-18 stack can be found here:https://devcenter.heroku.com/articles/heroku-18-stack.
See below for how this will affect Dash applications:
The requests package is no longer installed by default.
If an application uses requests it must be added to the applications's requirements.txt file.
If the application is usingdash-auth(* now deprecated) please remove that requirement(recommended) or add requests to the requirements.txt file.
If the application is using Dash Snapshot functionality, you must add requests to the requirements.txt file.
Additional system level package changes. You can view the full list here:https://devcenter.heroku.com/articles/stack-packages
Please note our pyodbc and oracle examples behave as expected, but if you run into related issues installing a custom package please reach out to our support team at onpremise.support@plot.ly.
Notes:
If you have any questions or would like our team to assist you with an upgrade, reach out to us at onpremise.support@plot.ly
Please be advised that, due to changes in the internal configuration, all Dash apps will be rebuilt during the upgrade and this rebuild can increase the time to complete the upgrade process.
The next major release of Dash Deployment Server will drop support for CentOS 6 and RHEL 6. Customers on affected operating systems are highly encouraged to upgrade their operating systems to a fully supported version.
The next major release of Dash Deployment Server will drop support for Docker 1.13 and below.

Notes:
If you have any questions or would like our team to assist you with an upgrade, reach out to us at onpremise.support@plot.ly
Fixed a race condition while loading the Dash Deployment Server Portal.
Fixed a page size parsing issue in the Dash Reporting Engine.
This release fixes an upstream bug which was causing some updates to be skipped during the upgrade process. We recommend upgrading Replicated manually before installing this release. Replicated can be upgraded by following the instructions in section 7.1.3 of the On-Premise v3.2.2 Installation and Upgrade Manual
Fixed bug with PostgreSQL database persistence. If you are using Dash Apps with the new managed PostgreSQL service provided in 3.2.0, please contact our support team before upgrading.
The next major release of Dash Deployment Server will support only Python 3.6.8, 3.7.3, and 2.7.16. If your app uses an older version, please update the Python version found in runtime.txt. This change can be made now, with DDS 3.2, so that you're ready for the next release. (Customers using DDS in airgap mode should contact our support team for more information.)
Dash Deployment Server now has limited support for high availability via Kubernetes for Dash Apps. For more information, please contact your sales representative.
Admin users can deploy and modify Dash Apps owned by any user.

Improved error messages are shown when Dash App deployment fails.
The Dash Proxy Timeout value now applies to all components used by Dash Deployment Server to serve Dash Apps.
Server-based parsing has been removed from Chart Studio. The "Upload Data" button in the "My Files" section now uses the same client-based parsing engine as the "Import" data in the "Create" section, and some files may be parsed differently. The /v2/grids/upload, /quandl, /proxy/plot, and /proxy/grid endpoints have been removed, and the /external endpoint only accepts data in CSV and Plotly Grid JSON formats.
Admin status is now updated for DDS users.
Conda dash apps are now supported by Dash Deployment Server.
Non-admin users can map selected host directories into Dash Apps.

Large request headers (up to 16k) are now supported for Dash Apps.
Server side parsing (accessible via the "Upload Data" button in Chart Studio's "My Files" section and from the /v2/grids/upload endpoint) has been updated, and certain files may be parsed differently. (Note that loading CSV and Excel files in the Plotly 2 Workspace is unaffected, and Dash Apps are unaffected).
Dash App login reliability has been improved.
The "login" button no longer appears briefly when visiting a portal that does not require login.
Error handling in the Dash App Manager has been improved.
Multicategory axes are now displayed correctly in Editor and Viewer.
LDAP login based on group membership now works for a group filter with an (objectClass=groupOfUniqueNames) structure.
Updated some database parameters to fix upgrading from very old versions of Plotly On-Premise.
Fixed an issue that caused a "GraphQL Error" for some users of the Dash Deployment Server Portal and Dash App Manager.
Improved the reliability of the image server component used in Dash Reporting Engine and to produce images for Chart Studio.

Logs for failed Dash App deployments can be viewed in Dash Deployment Server.
Custom TrueType fonts can be added to Chart Studio, and are used in plots and images.
Added support for EMF image generation.
Plots can be styled using themes (built in, user-owned, and shared themes are supported).
Enhancements to Chart Studio's grid functionality and the data selection workflow:
Pre-existing grids can be linked to a plot via the Import modal's URL tab.
Added ability to create multiple traces at once via the grid context menu.
Data references can be switched from one grid to another via the grid context menu.
Added grid drag-and-fill functionality for numbers, dates, weekday and month names.
Grid number display can be controlled via the grid context menu.
Falcon now includes a fully-featured query scheduler.
Falcon now supports BigQuery and Clickhouse.
plotly.js version 1.43.2, which includes:
Selection by clicking on points can be enabled via the new clickmode layout attribute and the select flag.
Stacked area charts - these are created via the new stackgroup and stackgaps attributes for scatter traces.
barpolar traces, which replace and augment area traces.
parcats (aka parallel categories) traces.
Dash App authentication is now performed by Dash Deployment Server, simplifying configuration and avoiding the need for the dash-auth package in most cases. If dash-auth is currently in use, you should upgrade to dash-auth==1.3.0 or newer, or else users will need to log in twice per app. See the authentication documentation for details.
An updated license file (.rli) is required for all customers using airgap (fully offline) installations. This should be installed before upgrading to this release. Contact Plotly On-Premise Support if you need an updated license file.
Customers who are upgrading from older Plotly On-Premise releases will need to ensure Replicated 2.31.1 or newer is installed before upgrading. Attempts to upgrade Plotly On-Premise to 3.0.0 or newer without doing this will fail with an error.
Dash Apps are no longer managed from "My Files" in Chart Studio. New apps will not appear in this view, and existing apps may not be updated. To manage app permissions, use the app's settings page in the Dash App Manager. For a user-visible list of applications, use the new Dash App Portal.
The PDF reporting endpoint for Dash Apps has been changed. See the API documentation for details.
The Chart Studio editor is now based on react chart editor, offering more trace types and more control over plot styling.
The Plotly White theme is used by default in the Chart Studio editor.
Collaboration workflow changes:
When a plot but not its underlying grid has been shared with a collaborator, the collaborator can edit the styles of the original plot without making a copy of the plot.
Collaborators cannot change the names of the plot or grid files that were shared with them, and cannot add new grids to shared plots (only the owner can do this).
When a folder is shared with a collaborator, all files within the folder are also shared.
The Dash Deployment Server now automatically redirects to include a trailing slash on Dash App domains. Dash apps will no longer be accessible without a trailing slash. This may pose an issue if an alias is being used for the DDS domain name and no trailing slash redirection occurs.
The SP Metadata URL will need to be updated if SAML was previously enabled. All authentication-related requests are now under a new /Auth path. The SP Metadata URL will be updated to reflect this change and the SAML IDP will need to be updated with this new SP Metadata URL.
Sharing a plot in private link mode no longer adds the share_key twice to the URL.
Various Dash Deployment Server stability fixes.
Backend PLOTLY_CUSTOM_STYLE works again.
Themes were tiered on onPremise instances, fixed.
Title of plot displays correctly on window tab.
Sharing and Embedding features work from feed again.
Removed Falcon query editor from inside of Chart Studio workspace. Queries can now be managed from the built-in Falcon instance, with a more fine-grained scheduler.
Certain chart editor features have not been ported to the new react-chart-editor: animation creation, mobile breakpoints, GeoJSON, certain annotation presets, certain analysis types and analysis metadata.
The grid metadata creation UI has been removed.
Fixed the imageserver service restart behaviour. The imageserver will now restart all necessary services when needed.
Fixed a security issue surrounding password resets under certain specific conditions.
Fixed error "containers have stopped unexpectedly".
Fixed odd UI behaviour in IE11.
Fixed stuck on "Starting content server.." when analytics is enabled.
Fixed deleting users via the admin portal.
Fixed/improved minor DDS UI behaviour.
Importing from SQL in the Chart Studio interface is now deprecated and will be removed in a future release in favour of the new and more powerful Falcon SQL Client features.
The next release of Plotly On-Premise will include a new Chart Studio editor. As a result, certain functions within the Chart Studio editor are now deprecated and may be removed: GeoJSON, certain MapBox styling options, analyses other than curve-fitting and moving-averages, the ability to create animations, the ability to configure mobile breakpoints, and per-data-point annotations. Please contact us if you are still using these features.
Domain based routing for Dash Apps is no longer supported.
The Dash Deployment Server has many new features and a fresh look for the web UI!
Dash App analytics and logs can be viewed using the web UI.
Environment variables can be added via the web UI. (These can be used to configure Dash Apps.)
