Saved views from two people are both kept. When you and a teammate each save a view of the same 3D model in a deck, both views stay, even if you save them at the same moment. A view one of you deletes stays deleted. A view a teammate saves while your new view's picture is still uploading is no longer lost when that upload finishes, and teammates see each view's picture once it has uploaded.
Play and Pause keep your deck saving. Pressing Play on a 3D model's saved views used to stop the deck from saving anything you did afterwards, so teammates stopped seeing your changes. Play and Pause now work, and everything you do after them saves as usual.
A clear notice when changes aren't saving. If your changes can't be saved, for example because you're offline, you no longer have permission to edit, or the deck has grown too big, a notice now says so and why, with a Retry button. The top of the editor reads Not saved instead of Saving… until your changes save again. A brief hiccup that the next try fixes shows nothing.
A heads-up before a deck gets too big. When a deck gets close to the most a single deck can hold, a notice tells you once, rather than on every save, and says what is taking up most of the space, so you can make room before changes stop saving.
Dropped files appear for teammates when they're ready. When you drop or paste an image, video or 3D model onto a slide, teammates now see it once it has finished uploading, instead of an empty frame in the meantime. You can still move it while it uploads. If you close the tab before it finishes, nothing is left behind, and if an upload fails, its placeholder is removed and you're told.
Splat files open in the splat viewer. A .ply or .spz file dropped onto a slide, or swapped in with Change model, now opens in the splat viewer, in the editor, when presenting and on share links. 3D widgets added this way before now open correctly too.
Embed links apply when you've finished typing. A link typed or pasted into an embed's link field now takes effect when you press Enter or click away, instead of reloading the embed with every keystroke, for you and for teammates. Esc puts the previous link back.
Viewing without edit access stays quiet. In a deck you can only view, an embedded Foveate file loading its preview no longer shows Saving… or asks you to confirm before you leave the page. A 3D model's Play button works for you without changing the deck, and saving views is left to people who can edit.
