๐Ÿ†•2024 Releases

May 21, 2024 - v128

New Features ๐ŸŽ

Insights on query performance

We are excited to announce a new feature that enhances the visibility and troubleshooting capabilities for queries underlying charts and tiles. With this release, you can now inspect your query performance details directly within the chart and tile editor.

This is especially useful with the release of our new โ€œHybrid pipelineโ€ feature (see more in ๐ŸŽข [Beta] Hybrid Pipeline), as Toucan smartly combines computation from your data source with its own query engine, making it more important to understand the performance breakdown.

Performance Diagnosis in Chart and Tiles

Our new performance entry provides a comprehensive view of YouPrep steps used by our Smart Editor to create the dataset used by your chart. This feature lets you quickly identify and analyze performance bottlenecks, ensuring optimal query performance.

Key Benefits:

  • Identify Slow Queries: Receive alerts when a query execution time exceeds a predefined threshold (e.g., 1 second), enabling you to promptly address performance issues.

  • Streamlined Troubleshooting: Quickly pinpoint and resolve performance bottlenecks by analyzing the execution time of each step within the hybrid query.

  • Detailed Step Breakdown: Expand individual operations to gain deeper insights into the translated query definition and other relevant details.

Getting Started

To access the new performance entry, simply navigate to the chart or tiles form where your hybrid queries are executed. You will see a dedicated section displaying the execution steps and their respective timings.

Improvements ๐Ÿ†™

Builder app navigation improvement

We have implemented UX improvements in the app navigation for builders:

  • It's now easier to return to the app store from staging mode with a dedicated button right in the staging bar. The headers of the configuration pages have also been improved for clearer navigation between sections.

  • You will see skeletons on the home page and stories so you'll have better feedback on page loading

  • The state of each tab is now saved so you'll find DataHub or Charts exactly how you left it before you switched

Better performance when designing an App

We're introducing performance boosts during the app-building experience, particularly when selecting a dataset to create a chart, exploring dataset information in the DataHub, or working with large datasets. How did we do it? We implemented a new approach to efficiently store and retrieve minimal dataset metadata alongside the dataset ID.

Font management dropdown

Now, selecting a font in the customization menu is easier, with the font name displayed in its own style, allowing you to preview and choose the right one!

Bug Fixes ๐Ÿ›

We have also highly invested in quality for this new release along with new features. See the detailed list below

May 7th, 2024 - v127

New Features ๐ŸŽ

๐Ÿ“’ Multiple PDF report

It's never been easier to create PDF reports with Toucan!

Builders can now design a compilation of PDF reports within a single application, and provide tailored reports for different end-user groups or analytical perspectives.

No need to juggle multiple apps to get various PDF reports anymore. Builders now have an easier and more scalable solution, reducing maintenance and costs.

With this new feature, it's still possible to edit and download PDF reports, as well as send them via email manually or on a scheduled basis.

With an enhanced mobile experience, empower your end users to effortlessly view, download or send by email the PDF report they need, whenever they need it, just as easily from a computer as from a mobile device.

Reach out to your Customer Success Manager to activate this new feature.

Group Privileges ๐Ÿ‘ซ

We're excited to announce the reintroduction of Group Privileges in Toucan 3.0, a feature that was part of Toucan 2.0, after a thorough rework of our technical architecture to make it more robust and scalable. Group Privileges give you greater control over access and permissions within your organization. You can manage users' application access by creating specific groups with shared permissions.

Please note that we've changed the mechanism: now, the most permissive privilege between user privilege and group privilege will be applied. For more details, please refer to our documentation.

Improvements ๐Ÿ†™

๐Ÿš€ Various performance improvements: we have implemented additional performance improvements on DataHub dataset display

๐Ÿ“–Minor changes: We've begun implementing small changes to improve the builder experience and simplify onboarding in our product. Our first update: in the staging bar, we've replaced the word 'Storytelling' with 'Charts' to make it clear that this interface is the central point for creating charts in the Storytelling App and, more importantly, for other layouts (PDF Report, Datawall, Dashboard Builder, My Favorites).

Bug Fixes ๐Ÿ›

V127 Bug fixes


  • The display of the Filter Panel on mobile wasnโ€™t working.

  • Preview in iPad was breaking bar chart display

Charts: Heatmap couldnโ€™t use dates as a label.

April 15, 2024 - v126

Improvements ๐Ÿ†™

๐ŸŽจ App Store redesign

We're pressing on with our product redesign, and in this release, we're introducing a fresh and sleek look to the app store. You'll immediately notice the new App Tile design, offering more space to showcase essential information in the most discoverable location for our users: latest edit, latest publish, and app ID copy. But that's not allโ€” we've also revamped the app information editing, duplication, and deletion experiences to offer further guidance.

One more thing: you can now customize the order of apps by simply dragging and dropping them.

๐ŸŽฅ Changing filter types

Previously, you had to delete a filter to change its type, but now you can do so directly.

Note: be careful, as changing a filter directly referenced within a dataset may disrupt the related dataset pipeline.

๐Ÿš€ Various performance improvements

The User Experience is closely tied to emotions. We're committed to continuously enhancing performance to ensure you experience a smooth and seamless analytics-building or reading experience, particularly with heavier apps. In this release, we've focused on improving the performance of different areas of our product. You may notice enhancements in DataHub loading times, particularly when loading datasets with significant dependencies, as well as improvements in filter loading times within your app. Stay tuned for more improvements to come soon!

April 1, 2024 - v125

Improvements ๐Ÿ†™

๐ŸŽจ Fresh Look for App Store & User Administration Headers

We've overhauled the headers in our App Store and User Administration to match Toucan's refreshed aesthetic. In your app store, you'll see that the search bar and app creation button are now positioned in a redesigned sticky header. The "admin area" button has been replaced by an icon, providing access to a new administration menu.

These updates mark the initial phase of a comprehensive redesign of the App Store, aimed at delivering a sleek, intuitive, and visually appealing experience. Stay tuned for more!

Improvements ๐Ÿ†™

๐Ÿ—บ๏ธ Drill in your map chart with ease ๐Ÿš€

We have made drill configuration with mapchart much easier! Simply fill the column including the level of hierarchy and we will manage the rest!

More in the documentation here

๐Ÿฆบ Safeguarded chart configuration

With the launch of Toucan 3.0, creating charts from raw datasets without data preparation is now incredibly simple, thanks to our automatic aggregation feature. Builders frequently utilize large datasets as inputs, which may inadvertently lead to feeding millions of rows into a chart during testing or due to misconfiguration, potentially causing browser crashes โŒ.

To prevent such issues, we've implemented a display limit on charts as a safeguard. This provides users with a second chance to refine aggregations and filtering before encountering challenges in their building process.

๐Ÿชฃ Discontinuation of some connectors

We're discontinuing support for low-usage connectors to enhance the user experience and focus on the most utilized ones. As a result, the following connectors will be removed: Adobe Analytics, Anaplan, Facebook Ads, Facebook Insights, Google Adwords, Google My Business, Hubspot, Microstrategy, Linkedin ads, Net explorer, Toucan, Trello, Wootric

Bug fixes ๐Ÿ›

New features ๐ŸŽ

๐ŸŽข [Beta] Hybrid Pipeline

We're thrilled to announce the beta launch of our new "hybrid pipeline" feature!

So, what's it all about? When we introduced Toucan V3, we unveiled our "NativeSQL" translator designed for YouPrep, our no-code querying interface, simplifying light data preparation. While YouPrep generates SQL queries sent to databases through our NativeSQL translator, not all YouPrep operations were available.

To address this, we've enhanced YouPrep by making all operations available - including Join ! - within the same dataset (referred to as a "pipeline"), prioritizing NativeSQL wherever applicable.

To gain access to the beta, simply reach out to your Toucan CSM to activate it on your workspace!

๐Ÿ’… Font Management

*only available when the White Label is enabled

Most of you wanted this for a while! Itโ€™s now out!

For customers embedding Toucan in their software, Toucan must align seamlessly with your product's Design System/Guidelines, where the font plays a pivotal role in meeting those expectations. In the past, changing the fonts in a Toucan app required using Custom CSS and making educated guesses about class names used within Toucan โ€“ but that's now a thing of the past ๐Ÿค  ! We've revamped the process for a more streamlined experience.

We've curated the most commonly used fonts in modern software, but if you have a font that isn't on the list, no worries! You can add your font hosted on a CDN to perfectly align with your design.

All this effort is backed by a fresh and new customization interface, laying the groundwork for exciting customization options in the upcoming months. ๐Ÿ‘€

Improvements ๐Ÿ†™

๐Ÿš€Interdependent Filters

Now, filters can interact with each other (please exercise caution to avoid infinite loops ๐Ÿ˜‰). Additionally, we've revamped the highlighting feature to help you locate your filters more easily and ensure effortless maintenance of your apps!

๐Ÿซก Hierarchical Filter is now orderable!

The feature was missing on this last type of Filter! Itโ€™s now available for every level!

๐Ÿฅง Circularchart is now sortable!

While the good practice is to still have it sorted in descending order, you can now reverse that and begin with the smallest arcs!

๐Ÿš€ Datahub metadata display has been improved!

The performance of metadata display in the Datasets tab of Datahub has been significantly improved, especially for applications with numerous dependencies and usages.

Bug fixes๐Ÿ›

February 5, 2024 - v121

New features ๐ŸŽ

๐ŸŽž๏ธ Unlimited Filters

We've extensively revamped our Home, Stories, and Dashboard layouts to provide a unified experience for Filters. Now, they share a brand-new header that allows you to pin an unlimited number of filters to every layout. Additionally, a smart adaptive Filter Panel appears when there's not enough space to display them within the header!

We're introducing a new Filter Settings panel within the layout editors, providing a single and clear area to manage all your filters!

We trust that these improvements will make app maintenance easy and enjoyable for you!

Find more details in the documentation.

๐Ÿ“บ Embedded Story now features in-header Filters!

Thanks to the enhancements made on Unlimited Filters, you can now embed a story complete with its header and pinned in-header filters! As an App Builder, this means you can embed designs tailored for extensive data exploration without depending on your web application's SDK tied to homemade filters.

Improvements ๐Ÿ†™

๐Ÿ–๏ธ Filter Creation

We've revamped the filter creation process to provide a clearer path for building them, preventing situations where incomplete filters could be created. The new form is more transparent, featuring an always-visible 'Create' button that is clickable only when mandatory options are filled in!

๐Ÿš€ Filter performance

We've boosted the performance of filters configured with numerous unique values! Choices within a filter are now capped, and users are encouraged to use the search feature to explore additional values.

Additionally, we now load only the filters pinned to the current layout, significantly improving performance when entering an app with a large number of filters!

As an App Builder, you can now enjoy a user-friendly suggestion interface to effortlessly format your dates in various configurations, especially within charts.

But here's the kickerโ€”you still have the power to manually input more intricate date formats using the familiar d3-time format. It's the best of both worlds for seamless date customization!

Improvements ๐Ÿ†™

Checkbox filters

  • The โ€œSelect allโ€ button only selects values that match current search terms!

  • End users can now select several values in a row and confirm their choice with a new โ€œApplyโ€ button! It will avoid several data calls for each value selected and improve the user experience!

  • There is a clearer icon to unpin filters to avoid confusion with the delete icon!

January 8, 2024 - v119

New features ๐ŸŽ

PostgreSQL: Managing Materialized Views!
