Power Pages version 9.8.8.x is now available. This article describes the bug fixes and updates that are included in this release.
The following list details issues that are resolved/updated in this update.
Accessibility
- Submitting a form now announces its processing state, so screen reader users know the action is in progress.
- Applying and clearing list filters is now announced correctly to assistive technology.
- List and collection item positions are now announced correctly to screen reader users on Android.
- Focus is now placed correctly on the invitation redemption flow, download actions expose the correct role to assistive technology, and the close button meets colour-contrast requirements.
Functionality
- Accurate session-expired messaging in list search: When a session expires during a list search, the portal now tells the user their session has expired instead of showing a misleading connectivity error.
- Reliability and performance improvements across the portal runtime: A set of under-the-hood improvements reduces resource consumption, improves responsiveness under sustained load, and prevents long-blocked requests from hanging.
- Quick view forms: Quick view forms no longer collapse when rendered in current versions of Chrome.
- Intelligent Charts: Chart rendering no longer fails when the underlying chart view cannot be resolved; an empty state is shown instead.
- Date picker: Selecting certain dates no longer causes the date picker to error.
- Search results: Web pages marked as excluded from search in Enhanced Data Model (EDM) are now correctly omitted from search results.
- Content security policy configuration: An intentionally empty content security policy setting is now honored instead of silently falling back to the default.
- Agent and chat endpoints: Authorization failures on these endpoints now return an appropriate HTTP error status instead of redirecting, so client integrations can handle them correctly.
- Content sanitization — Sanitization of HTML content delivered to portal visitors has been strengthened, including sanitization of user display names used in chat greetings.
- Response hardening — Sensitive and streamed responses are no longer cached by browsers or intermediaries, and internal portal identifiers, version details, and exception detail are no longer exposed in diagnostic responses.
- Automated crawler protection — The highest-volume AI and large-language-model crawlers are now blocked at the web server layer, reducing unwanted automated traffic and bandwidth consumption on portals.
- OData filter site setting: The
DisableOdataFiltersite setting is no longer honored for new sites or existing sites that hadn't used the setting by August 11, 2026. - Web API field configuration: Support for the wildcard value (
*) in theWebapi/<table-name>/fieldssite setting is deprecated. Explicit fields must be specified directly or through a Dataverse view named Power Pages Web API Columns by settingWebapi/<table-name>/UseFieldsFromViewtoTrue. - Web API wildcard detection: Site Checker now warns when
Webapi/<table-name>/fieldssite settings contain a wildcard (*) and identifies the affected site settings.
Library Upgrades
- Upgraded HtmlSanitizer from 4.0179 to 7.1.509
- Migration: PnP Sites Core to PnP Framework 1.17
New Features
- Custom JavaScript for modern lists: Makers can now attach custom JavaScript to modern list controls, enabling tailored client-side behavior on list pages without replacing the control. This is enabled by default in this release.
- Cloud flow triggers in Server Logic: Server Logic can now trigger Power Automate cloud flows directly, allowing makers to start automated business processes from server-side logic.
- Microsoft Entra ID sign-in for the live chat widget: The Omnichannel live chat widget on Power Pages now supports Microsoft Entra ID authentication.
