The October release introduces several new features and improvements and is delivered via a package update from the Microsoft Marketplace.

Please refer to the following instructions for updating the app in your tenant: How to update Sintel Apps

Attachments – Allowed file types and maximum file size ​

You can now configure which file types are permitted and set a maximum file size for attachments in both main and embedded forms. This provides greater control over file uploads and helps ensure that attachments meet your organisation’s requirements.

Form theme – Top bar colours ​

Form theme settings have been extended to allow customisation of the top bar colours, providing greater flexibility when branding forms to match your organisation’s look and feel.

Designer – Search functionality ​

A new search box has been introduced in the Sintel Apps Designer, making it easier to find fields, sections, logic, workflow settings, custom code and email content. This is particularly useful when working with larger or more complex forms.

Designer – Redesigned settings ​

Settings within the Sintel Apps Designer have been redesigned with on/off switches and descriptions explaining each state. This makes it easier to understand and configure the available options.

Logic – Improved navigation ​

When returning to the Logic tab, the Designer now automatically scrolls back to the previously selected condition or step. This makes it easier to continue working on complex logic without having to locate your previous position.

Token suggestions – Additional support ​

Token suggestions are now available in section descriptions, confirmation screens, the Set Section Description logic step and HTML, Header and Footer widgets. This makes it easier to insert dynamic field values without manually entering token names.

Signature field – Redesigned ​

The Signature field has been redesigned to allow users to either draw their signature or type it, providing a more flexible and convenient signing experience.

Yes/No field – Switch display mode ​

A new Switch display mode has been introduced for Yes/No fields, with the ability to define custom labels for each option. This provides greater flexibility in how Yes/No fields are presented to users.

Workflow actions – Improved confirmation messages ​

Workflow action confirmation popups now include a default confirmation message and the relevant action icon, providing users with clearer information when performing workflow actions.

Admin – App Permissions improvements ​

The App Permissions page has been reorganised to separate required and optional permissions, making it easier for administrators to understand and manage the permissions used by Sintel Apps.

Security improvements have been made to external form links, providing additional protection when forms are shared with external users.

September 2026 version 1.0.8 ​

The September release introduces a range of new features and improvements across the Sintel Apps Designer, Form Viewer, external collaboration, data management and Sintel BI integration.

Logic – Custom button visibility improvements ​

Improvements have been made to the custom button visibility logic step, providing greater flexibility when controlling when custom buttons are displayed on a form.

Data Export / Import ​

New data export and import functionality has been introduced, making it easier to transfer data between environments and supporting more efficient data management. This is particularly useful for forms containing lookup fields. For example, if you have a Travel Request form with lookup fields for Departments or Countries, the data stored in those lookup lists can now be included in the form export. When importing the form into another environment, the lookup data is automatically transferred, eliminating the need to manually repopulate the lists.

External collaboration – Custom email templates ​

You can now customise the email templates used for external collaboration invitations, allowing organisations to tailor the content and branding of emails sent to external collaborators.

External sharing – Custom invitation email templates ​

External sharing invitation emails can now be customised, giving organisations greater control over the messages sent when inviting external users to access shared forms.

Designer – Improved list name validation ​

Validation of list titles and internal names has been standardised when creating new SharePoint lists, providing a more consistent experience and helping prevent naming issues.

Calculated fields – Field tokens in formula editor ​

The calculated field formula editor now supports field tokens, making it easier to reference other form fields when creating calculations. This simplifies formula configuration and reduces the need to manually enter field references.

Bulk add unused fields to a section ​

You can now add all existing unused fields to a new section in a single operation. This speeds up the form design process, particularly when working with SharePoint lists containing a large number of fields.

Designer – Improved tooltips ​

Additional tooltips have been introduced throughout the Sintel Apps Designer, making it easier to understand the available settings and options when configuring forms.

External user token in specific users audience ​

The specific users audience configuration now supports an external user token, providing greater flexibility when defining visibility and access for external users.

Custom permissions for Sintel Apps Entra ID application ​

The Sintel Apps Entra ID application now supports custom permissions, enabling customers to configure the permissions required to trigger Power Automate flows.

Workflow History widget – Sintel BI integration ​

The Workflow History widget is now exposed for use with Sintel BI, supporting future enhancements that will allow workflow history information to be displayed within Sintel BI dashboards.

Designer – Settings navigation improvements ​

The settings navigation in the Sintel Apps Designer has been reorganised to make it easier to configure form settings.

Create lookup lists from Designer – Improvements ​

Further improvements have been made to the ability to create lookup lists directly within the Sintel Apps Designer, making the process of configuring lookup fields quicker and more convenient.

Form Viewer – Copy field value setting ​

A new setting allows you to enable a copy icon for supported fields within the Form Viewer, making it easier for users to copy field values. This functionality is disabled by default and can be enabled as required.

Tabbed sections – Error indicator ​

Tabbed sections now display an indicator when a field within a tab contains a validation error. This helps users quickly identify which tabs require attention before submitting a form.

Sintel BI – Export multiple lists ​

Support has been added for exporting multiple SharePoint lists at once, improving the data export process and supporting integration with Sintel BI.

Version History – Workflow Status field ​

The Workflow Status field is now included in item version history, providing better visibility of workflow status changes over time.

Form-level theme settings have been extended to allow customisation of Save button colours, providing greater control over form branding and appearance.

Tabbed sections – Improvements ​

Improvements have been made to the handling of tabbed sections within the Designer, making them easier to configure and manage.

Date fields – Improved date picker ​

The date picker experience has been improved, making it easier and more intuitive for users to select dates when completing forms.

PDF Export – Page numbering ​

Exported PDF documents now support page numbering, making multi-page documents easier to navigate and reference.

Sintel BI – Improved Data Export / Import integration ​

Sintel BI export and import functionality has been integrated with the new data export/import endpoint, improving compatibility and supporting more efficient data transfers.

JavaScript API – Filter list items by user email ​

The getListItems JavaScript API function now supports filtering list items by email address for user fields. This makes it easier to retrieve relevant SharePoint list items based on a user’s email address.

August 2026 version 1.0.8 ​

The August release contains some important changes and is thus delivered via a package update from the Microsoft Marketplace.

Please refer to the following instructions for updating the app in your tenant: How to update Sintel Apps

Form theme Import/Export ​

Within the Sintel Apps Designer you can now Export and Import a form theme which makes it really easy to consistently brand forms across your organisation.

Form fields placeholder setting ​

All fields now have a placeholder setting which enables you to define some default text to appear in them.

Allow setting a SharePoint-required field to read-only ​

Fields that are mandatory in a SharePoint list can now be made read-only within the form. This is particularly useful when upgrading a pre-existing list to use Sintel Apps without having to modify the settings of the existing fields in the list.

Allow creating lookup lists from designer ​

Lookup lists can be created directly from within the Sintel Apps designer which speeds up and simplifies the design process.

Logic – Step – Field – set value ​

Field values can now be set directly without the need to write JavaScript i.e configure it rather than code it.

Email editor – redesign ​

Significant improvements have been made to the email editor which make it much easier when defining emails on actions and workflow statuses.

Add possibility to open editor in after save script ​

After save code edit box now allows to open a popup with the code to make editing more convenient via “open editor” link.

Add ability to copy text from lookup fields and dropdowns ​

You can now copy the value selected in both lookup fields and dropdowns making the process of copying out data from forms much easier.

JS API – exitForm method ​

A new JS API method to close the form without saving with optional options: exitForm(options?: { dismissChanges: boolean }) where if dismissChanges is true, the form will not ask for confirmation when already modified.

JS API – triggerLogic function ​

This method allows forcing the logic re-evaluation when e.g. some custom asynchronous operation finishes (e.g. some data fetch) and logic should be reevaluated.

Designer – Add tooltips on hover ​

In the designer some dropdowns got tooltips showing the whole value of available options on hover, especially useful if long names are used with a similar beginning, e.g. when selecting a section or a workflow status in logic.

Add thousand separator setting to number fields ​

You can now choose to display or not display a thousand separator on numeric and currency fields.

Add multiline text field max length setting and character count indicator ​

You can now define the maximum number of characters permitted in multiline text fields and also enable an automatic character count on those fields.

External access – improved security and rate limiting ​

Our custom auth is now more secure by more closely checking what a user is allowed to do in a given external flow (anon, collab, external share etc.) minimizing the risk of exposing unwanted data. Limiting the number of possible retries in OTP scenarios.

Set expand/collapse section icon colour to match configured section icon colour ​

When using collapsable sections their expand/collapse icon colour now matches the defined section colour.

We introduced a new Header/Footer widget that can be used on forms to speed up the design process. The widget supports a number of settings including the text for the header, subheader, images and a description. Its configuration can also be easily copied and reused across forms.

Expose Workflow History widget to BI ​

The form workflow history has been exposed for use within Sintel BI. In an upcoming update to Sintel BI, it will be extended to permit the display of the workflow history on Sintel BI dashboards.

Switch from sending Graph emails to Postmark ​

To improve our email delivery mechanism we have moved from using the Graph API to using Postmark for sending emails. More details can be found here: Sintel Apps Email Delivery

Emails – allow custom email configuration for clients using their own shared mailbox ​

Customers can now define a custom emails address to send emails from. More details can be found here: Custom Emails

Designer – allow editing settings even if they are disabled ​

Some settings (e.g. Confirmation screens, workflow email notifications) allow to be edited (e.g. the confirmation HTML or notification email recipients, body etc.) even if the functionality itself is disabled in the form (e.g. workflow status notification or confirmation screen options are disabled) – allows easier config preparation without the need to activate functionalities before they are fully configured.

Tokens support in save confirmation screen ​

Confirmation screen HTML templates now support tokens like the notification emails do – allowing more context-aware confirmation screen data, e.g. You have successfully submitted the item: {{Title}}. Caution – data is taken from the contents of the form while it was being submitted, potential after save script changes will not be available. Special case: {{ID}} token, which will always be properly resolved.

May 2026 version 1.0.7 ​

The May release is delivered over the air and is applied automatically, with no action required by customers. This release focuses on expanding SharePoint compatibility, enhancing workflow and history tracking capabilities, improving form design flexibility, refining user experience across fields and related lists, and introducing additional configuration options for administrators and developers.

SharePoint Calculated Field Support ​

Sintel Apps now supports existing SharePoint calculated fields directly within forms. Supported result types include Text, Number, Percentage, Currency, Date & Time, Date Only, and Boolean values. Calculated fields are always displayed as read-only and automatically update based on their SharePoint formulas. Calculated fields cannot be created from the App Designer. Only existing SharePoint calculated fields can be added to the app. Calculated field tokens are also not supported in email templates.

SharePoint Required Field Flexibility ​

Fields configured as required in SharePoint can now be set to read-only within forms. These fields continue to validate as required and can be populated through form logic, enabling more advanced automation scenarios. e.g. An Employee ID field may be configured as required in SharePoint to ensure every record contains a valid identifier. The field can now remain read-only on the form while being automatically populated by form logic or workflow actions, allowing validation requirements to be met without user input.

Internal Name Handling Improvements ​

Additional safeguards have been introduced when creating SharePoint lists named “Forms”. The platform now automatically applies an alternative internal naming convention to avoid conflicts with SharePoint system folders and preserve configuration version history.

Workflow History Display Options ​

New configuration options offer greater control over the presentation of workflow history. Administrators can now display:

  • Full workflow history
  • Actions only
  • Statuses only

These settings apply to both the workflow history panel and individually for workflow history widgets.

Workflow History Email Token ​

Email templates now support the new {{[workflowHistory]}} token, allowing workflow history information to be embedded directly into notification emails as a structured table.

Conversation Token Expansion ​

Support has been added for the {{Author}} token within conversations. This helps provide additional context during collaboration and review processes, especially when forms are updated or discussed by multiple users.

Field Change Detection API ​

The JavaScript API now supports field change tracking through the hasFieldChanged() method. For example, if a number field changes from 10 to 15, the method returns true the next time it is evaluated and records the new value. Subsequent evaluations return false until the field changes again, simplifying the implementation of reactive form logic and custom scripts.

Field Value Changed Logic Condition ​

A new Field Value Changed condition has been added to form logic, enabling actions to be triggered only when a field changes value. For example, if a field starts with a value of 100 and is changed to 150, the condition evaluates to true and updates its reference value to 150. It will not evaluate to true again until the field changes to a different value, such as 200. To ensure consistent behaviour, the Field Value Changed condition should be placed first in a condition group. In certain scenarios involving OR operators, later conditions may not be evaluated due to standard condition short-circuiting.

Form-Level Email Notification Control ​

Administrators can now disable workflow, sharing, and comment-related email notifications at the form level during testing or implementation phases. One-Time Password (OTP) emails remain unaffected to ensure external collaboration continues to function.

Related lists have been optimised for mobile devices, improving usability and responsiveness when viewing associated data on smaller screens.

Horizontal Scrolling Layout Support ​

Related lists and related libraries now support a new layout mode that enables horizontal scrolling. Administrators can choose between:

  • Fit to Width (default)
  • Single Row with Scroll

This provides significantly greater control over displaying large datasets with many columns.

Feature Availability Indicators ​

The designer now clearly identifies features that are unavailable under the current license, providing contextual explanations and reducing configuration confusion.

Calculated Formula Editor Improvements ​

Calculated formula properties now use a multi-line editor, making complex expressions easier to create, review, and maintain.

Spacer Widget ​

A new Spacer widget has been added to help designers create cleaner and more flexible form layouts. The widget can be used to introduce visual separation between form elements and sections, improving readability and form organisation. Optionally, designers can configure a single line of text with token support to display lightweight informational content directly within the spacer.

Updated Application Icons ​

Application icons have been refreshed to improve visual consistency across the platform.

Rich Text Image Pasting ​

Multi-line rich text fields now support direct image pasting, improving content creation and reducing reliance on external image uploads.

Single Choice Dropdown Improvements ​

Single-choice dropdown fields now automatically expand when users click anywhere within the editable area, creating a more intuitive selection experience. Height consistency issues have also been resolved.

Hide Stepper Buttons – Number Field Configuration ​

A new configuration option allows administrators to hide the numeric input up/down controls (chevrons) for number fields.

Dropdown fields now clear search value on blur

Sintel BI Dialog and Embedded Mode Redirect Support ​

Forms running within Sintel BI now support redirection to View and Edit modes after save operations, enabling smoother embedded form experiences.
