Details

• Bugfix - Add open button to PDF viewer on iOS/iPadOS: #13797

  On iOS/iPadOS, we now display a button to open the PDF file in the browser
  instead of the native PDF viewer. This is a workaround to avoid issues with the
  native PDF viewer on iOS/iPadOS.

  #13816

• Bugfix - Fix danger filled button text color on focus: #13887

  We've fixed the OcButton danger filled variant not applying the correct text
  color when focused via keyboard.

  #13887

• Bugfix - Open external apps based on the file mime type: #13888

  We've fixed the external app redirect (/external) picking an arbitrary app
  when no app query parameter was present. It fell back to the first registered
  app provider, which might not support the file's mime type, so the following
  request to open the file failed with an "app not found" error that surfaced as a
  generic error to the user.

  The redirect now resolves the app from the file's mime type, preferring the
  configured default application, and shows an explicit error when no suitable app
  is available instead of silently redirecting to the wrong one.

  #13888

• Bugfix - Validate URL before opening password-protected folder: #13924

  We've fixed an issue where the URL stored inside a .psec file was not
  validated before being used as the source of the folder view iframe. The URL is
  now checked to ensure it uses a safe scheme and points to the configured
  ownCloud server.

  #13924

• Enhancement - OwnCloud branded login background: #13875

  The default login page background has been replaced with the ownCloud branding
  background. The background image is now applied through the CSS custom property
  --oc-login-background-image, so a future branding update only needs to change
  one value. The image itself still comes from the theme
  (loginPage.backgroundImg in theme.json) and remains fully customizable.

  #13875

• Enhancement - Add a documentation screenshot capture tool: #13894

  We added a Playwright-based tool under tests/e2e/docs that automatically
  captures end-user documentation screenshots from a live ownCloud Web instance.
  Each "tour" drives the UI through a documented flow and saves a captioned
  screenshot per step plus a manifest.json, so the screenshots used in the user
  documentation can be regenerated on demand and never drift from the product. The
  initial tours mirror the "Web for users" documentation: the top navigation, the
  file sidebars, sharing roles and contextual help.

  #13894

• Enhancement - Add an HTML editor app: #13895

  We added a new app, web-app-html-editor, that opens .html, .htm and
  .xhtml files in a CodeMirror source editor with a live preview. The file is
  loaded and saved over WebDAV by the standard app wrapper, and the document is
  rendered in a strictly sandboxed iframe (opaque origin, no network egress) with
  Editor, Split and Preview view modes. The app is registered by file extension
  and follows the same thin pattern as the text editor.

  #13895

• Enhancement - Save a copy of office documents to another format (Collabora): #13906

  Office documents opened in Collabora Online could be renamed but not saved as a
  copy or exported to another format back into oCIS storage: "Save As" silently
  did nothing. Collabora exposes "Save As" as a host-delegated operation - it
  posts a UI_SaveAs message and waits for the integration to reply with the
  target filename via Action_SaveAs - but the app-provider integration never
  opened that postMessage channel.

  The app-provider now announces itself to the editor with Host_PostmessageReady
  once the iframe has loaded, requests the grouped Save-As control via
  ui_defaults (SaveAsMode=group), and on UI_SaveAs prompts for the copy's
  name and replies with Action_SaveAs. The collaboration service already
  implements WOPI PutRelativeFile, so the copy is written into the same space,
  respecting the user's permissions. The chosen file extension selects the export
  format (e.g. docx to pdf/odt, xlsx to ods, pptx to pdf).
