Library Mobile 2026 May Release Notes

Developments

Home Page and Web App upgraded to React 19

The Library Mobile Home Page and Library Mobile Web App has been upgraded from React 18.3 to React 19.2, which is currently the latest version of React. This change fixes some outstanding accessibility issues, and generally brings infrastructure up-to-date, making the Library Mobile more stable, easier to maintain, and quicker to develop.

Customers using custom CSS and Javascript on the Home Page are strongly advised to test for regressions in the May 2026 Preview environment, with a special emphasis on sidebar behavior, as the sidebar has been significantly restructured. No action is required for customers who do not use customer CSS and Javascript on the Home page, and no UI change is expected for end-users, aside from accessibility improvements.

For more information on React versions, see the Versions page on the official React website.

Bug Fixes

SF number	Platform	Description
N/A	All	In certain scenarios, favoriting a subtile from inside an admin container sometimes did not behave as expected. This was fixed.

N/A	Android	The heading in the Biometric Lock screen was not formatted as such, making it difficult for users with screen readers to read. This was fixed.
N/A	Android	Upon login, after a user chose to enable a biometric lock for the app, but then canceled before completion of the flow, the Try Again button appeared overlaying an image, making it unreadable. This was fixed.
N/A	Mobile	Accessibility for campusM Maps was improved on mobile for screen-reader users.
08269387	iOS	In some cases, users on the iOS app had to reauthenticate when viewing content through the campusM browser. This was fixed.

N/A	Mobile	The accessibility of the search bar component in the Events PI was impoved for screen-reader users.
N/A	Mobile	In some cases, subtile text inside of tile containers was truncated after one line when the tile container was 2 tiles high, which is unexpected. Now, this will only happen in certain cases when a container is 1 tile high, as designed.
N/A	Mobile	In List View of the Arrange functionality, disabled buttons were focusable, and some buttons were not announced correctly when using a screen-reader. This was fixed.
