+This [new QuickStart](https://quickstarts.sigmacomputing.com/guide/functions_popular_functions/index.html?index=..%2F..index#0) highlights Sigma’s most frequently used functions (according to CS) through practical, retail-data examples—covering the core patterns users rely on every day.
+
+- Categorize values with BinFixed and BinRange
+- Handle nulls cleanly with Zn and Coalesce
+- Search and classify text with Contains and RegexpExtract
+- Filter efficiently with In, IsNull, IsNotNull
+- Enrich analysis using Lookup
+- Understand contribution with PercentOfTotal and Subtotal
+- Apply clean multi-condition logic with Switch
+
+These patterns cover the 80/20 of everyday workbook building—categorizing values, fixing nulls, parsing strings, enriching with lookups, and calculating contributions without SQL detours. Faster builds, fewer mistakes, clearer insights.
+
+A full, prebuilt workbook template is available so users can explore every example without building the workbook themselves. Great for learning the functions quickly or using the workbook as a reference model.
+
+The [Common Date Functions QuickStart](https://quickstarts.sigmacomputing.com/guide/common_date_functions/index.html?index=..%2F..index#0) also has a template now too!
+
+### OAuth 2.0 & PKCE for Secure Data Integration
+This conceptual [QuickStart](https://quickstarts.sigmacomputing.com/guide/security_oauth_pkce_secure_integration/index.html?index=..%2F..index#0) breaks down how to use OAuth 2.0 with PKCE to secure Sigma’s access to cloud data platforms—especially in embedded scenarios.
+
+Security teams and architects need a clear, shared model for how Sigma authenticates and queries on behalf of users.
+
+This QS gives a vendor-neutral, implementation-aware overview that you can use to:
+- Pick the right pattern for your Sigma deployment (internal vs embedded, per-user vs service account)
+- Understand where PKCE fits and how Sigma supports
+- Talk credibly with security, platform, and app teams about risk, audibility, and compliance
+
+IMPORTANT NOTES:
+Conceptual only — no hands-on build or trial setup required
+Aimed at security architects, data platform owners, and embedding developers who need a design-level view
+
+
+
+
+## Security
+Duration: 20
+
+### Implicit TLS now supported for custom SMTP servers
+You can now use `implicit Transport Layer Security` (TLS) when configuring custom SMTP servers by using **port 465.**
+
+For more information, see [Configure a custom SMTP server](https://help.sigmacomputing.com/docs/customize-welcome-and-invite-emails#custom-smtp-server)
+
+### Set up an app for two-factor authentication (GA)
+If you use a username and password to log in to Sigma, you can set up an authenticator app to generate two-factor authentication codes instead of having codes sent to your email address.
+
+You can turn off the app-based two-factor authentication at any time, or an admin can reset it, to receive two-factor authentication codes via email instead.
+
+For more information, see [Set up an app for two-factor authentication](https://help.sigmacomputing.com/docs/app-based-authentication-for-users)
+
+
+
+
+## Workbooks
+Duration: 20
+
+### Add Cc and Bcc recipients to email bursts
+You can now add Cc and Bcc recipients to email bursts.
+
+For more information, see [Export as email burst](https://help.sigmacomputing.com/docs/export-as-email-burst)
+
+### Aggregate totals across higher grouping levels (GA)
+When displaying subtotals in your pivot table, you can now change whether the row subtotals are aggregated and displayed just for the immediate parent pivot rows, or also displayed at higher grouping levels.
+
+For more information, see [Aggregate totals across higher grouping levels (Beta)](https://help.sigmacomputing.com/docs/working-with-pivot-tables#aggregate-totals-across-higher-grouping-levels-beta)
+
+### Auto-update page anchor names in the navigation element
+When the name of a page anchor is changed, the names of any associated navigation options in a navigation element now automatically update to match the new name.
+
+### Change divider stroke styles
+You can now change the Stroke style for divider elements to Solid, Dashed, or Dotted.
+
+For more information, see [Divider](https://help.sigmacomputing.com/docs/intro-to-ui-elements#divider) in Intro to UI elements.
+
+### Conditional background colors for containers
+You can configure formatting rules that conditionally change the background color of a container. For more information, see [Style a container](https://help.sigmacomputing.com/docs/use-containers-to-organize-workbook-layouts#style-a-container)
+
+### Create and filter hierarchies (Beta)
+Use hierarchies to group columns categorically and define the order of data granularity. When you create a hierarchy, you can:
+
+- Define the order of the hierarchical data.
+- Easily visualize all parts of the hierarchy together in a pivot table or grouped table.
+- Format all levels of the hierarchy consistently, such as when applying conditional formatting.
+
+If your hierarchical data is ragged, Sigma visualizes the ragged hierarchy, letting you view your hierarchy in a dense layout instead of empty rows like a non-ragged hierarchical view.
+
+For more information about creating a hierarchy column, see [Work with hierarchies](https://help.sigmacomputing.com/docs/hierarchies) and the function reference for the [RaggedHierarchy function](https://help.sigmacomputing.com/docs/raggedhierarchy)
+
+After you create a hierarchy, you can filter different levels of the hierarchy using a filter on the data element or with a hierarchy control element.
+
+For more information, see [Hierarchy control](https://help.sigmacomputing.com/docs/intro-to-control-elements#hierarchy-control)
+
+### Customize page headers (GA)
+You can enable custom page headers to appear on one or more workbook pages.
+
+Page headers allow you to repeat contents like titles, filters, or navigation options across multiple pages in a single configuration.
+
+Scroll options allow you to create a sticky header that moves with the user as they scroll.
+
+For more information, see [Add custom page headers to a workbook](https://help.sigmacomputing.com/docs/add-custom-page-headers-to-a-workbook)
+
+### Customize text fonts and sizes
+You can now use custom fonts and sizes for text elements, in addition to using preset text styles, by using `Break` style and `Restore` style.
+
+For more information, see [Text elements](https://help.sigmacomputing.com/docs/text-elements#/apply-formatting-to-a-text-element)
+
+### Image backgrounds for containers
+You can configure background images for containers from an upload, as well as static and dynamic image URLs.
+
+For more information, see [Style a container](https://help.sigmacomputing.com/docs/use-containers-to-organize-workbook-layouts#style-a-container)
+
+### Legacy workbook layout (Deprecated)
+**The classic or legacy workbook layout is deprecated.**
+
+On March 3, 2026, editing of workbooks with legacy (non-grid) layouts will be disabled and you must upgrade workbooks to grid layout.
+
+On June 2, 2026, this functionality will reach end of support and workbooks will be automatically upgraded when the workbook is opened.
+
+For more information, see [upgrade workbooks to grid layout](https://help.sigmacomputing.com/docs/upgrade-workbooks-from-legacy-layouts-to-grid-layouts)
+
+### Navigation element (GA)
+You can use the navigation element to display a list of destinations users can visit.
+
+The navigation element shows each option as an individual button, which you can configure to send users to a workbook page, workbook element, or external link when clicked. Submenus allow you to nest additional navigation options under a top-level option.
+
+
+
+For more information, see [Use the navigation element to guide user exploration](https://help.sigmacomputing.com/docs/use-the-navigation-element-to-guide-user-exploration)
+
+### Reference multi-select control values in custom SQL
+You can now reference the selected values of a multi-select list values control in custom SQL queries.
+
+The selected values can be used to filter results in subqueries and CTEs, combined with formulas like ArrayLength, and more.
+
+For more information, see [Reference multiple values from a multi-select list in SQL](https://help.sigmacomputing.com/docs/reference-workbook-control-values-in-sql-statements#reference-multiple-values-from-a-multi-select-list-in-sql)
+
+### Select all search results in list and hierarchy filters and controls
+When using search in a list or hierarchy filters and controls, you can now select all values from the search results.
+
+### Worksheets and dashboards (Deprecated)
+Worksheets and dashboards are now deprecated (dataset worksheets continue to be supported).
+
+**To ensure continued access to your content, convert worksheets and dashboards to workbooks.**
+
+On March 3, 2026, editing of worksheets and dashboards will be disabled.
+
+On June 2, 2026 this functionality will reach end of support and existing worksheets and dashboards will no longer be available.
+
+For more information, see [convert worksheets and dashboards to workbooks](https://help.sigmacomputing.com/docs/convert-worksheets-and-dashboards-to-workbooks)
