Cloud Filter Extension 3.2.2 (August 2025)

Release Date: 5 August 2025

Fixed an issue where the Extension applied Web Filter policies for a tenant-specific Outside Premises location to all tenants.

 

 

Cloud Filter Extension 3.2.1.2 (July 2025)

Release Date: 15 July 2025

When a Safeguarding Alert is sent, the Extension now uploads Cloud logs immediately (as well as uploading batches every 5 minutes), so data is aligned between Safeguarding Alerts and Cloud Reporting.

We’ve also fixed excessive Safeguarding Alert generation.

Plus, we’ve made several improvements to how the Extension works with YouTube:

  • Improved loading speed and blocking of links and thumbnails in the sidebar.
  • Fixed an issue where videos in our Blocklist that were added to a Custom category weren’t blocked, and the category didn’t show on the Block page or Real Time Filtering Log Viewer.
  • Fixed an issue where Restricted Mode would still be forced on when the YouTube SafetyMode Cookie Content Modification was turned off.
  • Fixed two issues that caused setting overlays (such as Device theme, Language and Restricted Mode) not to show when clicked.

 

 

Cloud Filter Extension 3.2.1.1 (April 2025)

Release Date: 15 April 2025

  • Minor performance improvements for Content Modifications.
  • Improved the performance of YouTube when you use Video filtering.
  • We check when the device last communicated with Cloud Filter using the Secret Knock, so we can apply Mode 2 filtering soon after devices are woken up from sleep.
  • We fixed an issue where users could press play before BBC iPlayer - Enforce parental guidance lock blocked the video.
  • Force SafeSearch now works for ecosia.org.
  • The ‘Blocked by Smoothwall’ message for Google Content Modifications works better with other page elements.
  • Improved how our IWF List lookup checks user activity, including better matching against query parameters and only checking web-accessible URLs in the IWF list.
  • Fixed an issue where items added to Domain/URL filtering with capital letters would not be filtered as expected. Domain/URL filtering is no longer case-sensitive, so blocking EXAMPLE.COM will now match example.com.
  • Changed how we look up data to better match URLs to the right Category.

 

 

Cloud Filter Extension 3.1.5 (February 2025)

Release Date: 27 February 2025

  • We’ve significantly improved blocklist patching so it doesn’t stall the browser, including speeding up the time taken to download the new blocklist if it fails. This update fixes most instances of slow browsing you may have experienced.
  • We fixed an issue for Chromebooks provisioned using Google Admin, which showed empty or out-of-date information for the public IP address and log upload time.
  • Fixed the Last Sent Logs field within Diagnostic Information for devices provisioned in Native mode. It now matches the main Diagnostics page and shows the timestamp rather than ‘Never’.
  • Content Modifications that modify content based on URLs now work with the extension.
  • We fixed an issue with non-instant Safeguarding Alerts about themes other than Suicide, which were duplicated within the email.

 

 

Cloud Filter Extension 3.1.4.2 (January 2025)

Release Date: 10 January 2025

Resolved an issue where access to PDFs was blocked because they were incorrectly classified as IWF violations.

 

 

Cloud Filter Extension 3.1.4 (January 2025)

Release Date: 9 January 2025

  • Improved browsing performance by optimising IWF List lookup and splitting up blocklist loading so you can load pages quicker during startup.
  • We also boosted the speed of content analysis by introducing caching for child phrase lookups and reducing unnecessary tab re-scanning.
  • You no longer see a ‘Blocked by Smoothwall’ message and need to refresh to access an allowed video when the rest of YouTube is blocked.
  • We’ve fixed the YouTube - Remove Adverts Content Modification, and selecting ‘Skip’ takes you to the start of the video rather than the end.
