Version 9.1.0

## Version 9.1.0 - September 1, 2024

  - **Improved:** Use file extension arrays instead of enumerating image and documents formats so that FileManager is displayed
    faster when the page is first accessed (on application startup). Enumerating formats to find Document Viewer and Image Viewer support,
    triggered loading of native DLLs, which should be delayed to when they are actually used.

  - **Improved:** Disabling Download permission in an access control will also disable DocumentViewer's DownloadAsPdf action.
    In the past we allowed DownloadAsPdf as the user could already print the document and save as PDF but it makes more sense
    to disable it to prevent confusion as it has "Download" word in it.
    So currently;
    Disabling Download permission -> disables DocumentViewerPermissions.Download and DocumentViewerPermissions.DownloadAsPdf
    Disabling Print permission -> disables DocumentViewerPermissions.Print and DocumentViewerPermissions.SelectText

  - **Fixed:** Since v9.0.0, when clicking "Download Original" button in DocumentViewer, the download dialog prompted
    to save "SessionExpired.html" instead of the actual file. This was caused by stateId being overwritten by FileManager.

  - **Fixed:** Embedded resource overriding from App_GlobalResources folder was broken since v9.0.0.
    For example custom language files put under App_GlobalResources, were not being loaded.

  - **Improved:** Document Viewer:
    - **Improved:** PDF conversions are now faster and more accurate. Support high-load environments.
    - **Improved:** DocumentViewer will show generic subfolders for attachments that has path info in PDF portfolio files.
    - **Fixed:** Signatures in some PDF files were removed in conversions and thus were not visible in DocumentViewer.
    - **Fixed:** "Full Screen" menu item should not be visible on mobile devices just like "Presentation Mode".

  - **Improved:** Delete legacy folders and left-over temporary files under GleamTechConfiguration.TemporaryFolder on startup.
