To avoid a major bug, you must rebuild your multi-folio apps to a minimum of v30 and submit an update to Apple as soon as possible, before iOS 8 is released. Failure to update apps will likely result in DPS apps not functioning properly when iOS 8 is released publicly. If you currently have a v30 or v31 multi-folio app, your app must have been built after August 18.
The v31.3 August 18 release included an update to the v30 and v31 multi-issue viewers that addressed the following major problem with DPS running on iOS 8:
On iOS 8 beta cover icons do not appear, downloaded folios are lost and cannot be viewed, and folios cannot be downloaded after the user launches the app for the first time, quits the app, and restarts it.
This issue does not affect single-folio apps.

Before building the app, please be aware of a bug related to auto-hiding scrollbars that was introduced with the v31.3 release on August 18. Normally, when the “Enable auto hiding of the vertical folio scrollbar” option is selected, the feature is enabled. The bug reverses this behavior, meaning that selecting the option disables it. Thus, to enable this feature, you must deselect the “Enable auto hiding of the vertical folio scrollbar” option. This bug will be corrected with the upcoming v32 release of DPS. Please remember to enable this option again, if desired, when you next build your app.
