- the Table of Contents stickiness now covers the full height of the viewport, before it was limited to 100vh - we listen the scroll to highlight the heading in the Table of Contents only when the Table of Contents is open - We debounce the editor change to avoid excessive updates to the Table of Contents

We notices that `context.getChanges` was very greedy, on a large document with multiple users collaborating, it caused performance issues. We change the way that we track a upload by listening onUploadEnd event instead of tracking all changes in the document. When a doc opens, we check if there are any ongoing uploads and resume them. We fix as well a race condition that could happen when multiple collaborators were on a document during an upload.
