- Made Library file clicks respond immediately and restored clickable folder breadcrumbs, so opening a resource no longer appears to pause while its preview starts.
- Made resource files open significantly faster by reusing Library metadata that is already loaded, starting preview work earlier, and reducing repeated server lookups without weakening access checks.
- Made Library folder navigation near-instant with in-place cached transitions, improved Back and Forward navigation, and fixed transition crashes and excessive background loading requests.
- Made user emails in Admin Activity clickable so admins can open the existing user resource-analytics view directly without losing their current Activity filters or page.
- Strengthened site security with safer error handling, tighter browser script protections, a non-root production runtime, and pinned build automation dependencies.
- Made the Resource Library feel much faster by warming the Library before it is opened, preloading likely next folders in the background, and showing an immediate compact loading state instead of leaving users wondering whether a click worked.
- Fixed an intermittent first-load Library failure caused by server and browser date rendering differences, and reduced folder wait time with cached indexed folder views and parallel metadata loading.
DP Resources
Changelog
A listed record of all the features, improvements, and fixes released to the website.
DP Resources updates
- Fixed duplicate Question Bank topics and subtopics across subjects by normalizing provider and syllabus prefixes consistently, including coded and lettered topic labels.
- Fixed the Question Bank course search field in dark mode so it uses the themed search surface instead of showing a white inner input.
- Fixed Library source browsing so normal subject, level, assessment, and navigation folders no longer appear as Source under review, while reviewed source labels such as Padlet remain attached to the actual resources they describe.
- Made Library folder headers more compact by keeping Back navigation and Browse by source together beside the folder controls, removing the awkward empty space between the folder heading and its contents.
- Refreshed What’s new with the final 16 August release highlights, an exact release date, and a new once-per-release prompt while keeping the full changelog available for detailed updates.
- Improved folder controls in the Resource Library by grouping Search this folder and Filter with the view controls, and making Filter close naturally when clicking elsewhere or pressing Escape.

- Rebuilt the Admin Library index into a live command center with real progress, current activity, throughput, ETA, safe pause and resume, and resumable refreshes.
