Darkness & Light HDR photos now show their full brightness on supported displays. A rebuilt histogram reveals more detail, and new warnings mark blown highlights, blocked shadows, and HDR highlights beyond your display. Live Photos stay together as one item through browsing and file operations, with motion playback in the viewer. Animated GIF, PNG, WebP and HEICS play too. Keep culling: jump straight to the next unflagged or unrated photo. Also: multipage TIFF and MPO page browsing, focus peaking in cyan and magenta, clearer settings and image info. Under the hood: faster folder opening, 5× faster HEIC navigation, metadata read once and shared across views, and dozens of fixes.

Stacks in the Viewer: A burst now reads as a pile in the viewer too. Command-Down opens a stack, Command-Up closes it, everywhere. A closed stack behaves as a single photo, so stars, color labels, picks, rejects, and rotation apply to every frame. Smarter Burst Detection: Grouping now compares the images themselves, not just capture time and camera, so more real bursts are found. Survey Upgrades: Visible pick and reject buttons on every tile, adjustable tile size, and an animated step in from the viewer. Pick Up Where You Left Off: Seula reopens the folder, the photo, and the view you were last in. A photo opened from Finder lands straight in the viewer, with its folder behind it. Faster and Lighter: A large photo releases its memory when you leave it, scrolling no longer touches the disk for every tile, and refreshing a folder skips the metadata re-read. Also in this update: - The rating bar can be always visible, shown on hover, or hidden. - The info panel now works in Compare. - Arrow keys navigate the grid, and Shift extends the selection. - Double-click a filmstrip thumbnail to swap the focused pane in Compare. - An unreadable folder now says so and offers to retry instead of looking empty. - Dozens of smaller fixes, including a long freeze when opening the first photo in a large folder.

Stacks: Seula now groups burst shots together automatically by capture time and camera, collapsing them into a single stack card in the browser. Expand, split, merge, or dissolve a stack anytime, and every correction is undoable. Jump into a stack from the viewer, or open one straight into Survey or Compare. Burst Review: Work through every stack in a folder one at a time. Pick your keepers with one tap and the rest are marked rejected automatically. Undo anytime, even mid-save. Blink Compare: Press B in the viewer to instantly flip between a photo and its nearest neighbor at the same zoom and position, great for spotting the sharper frame in a series. Metadata Filters: Filter by camera, lens, file type, orientation, or ISO, with a live count for every option, right alongside your star, color, and flag filters. Mouse Button Shortcuts: Bind your mouse's side and middle buttons to any command, just like keyboard shortcuts. Also in this update: - Color and flag filters are now multi-select, so you can combine picks and unflagged, or yellow and red, in one view. - Survey mode gets a full-window peek with the spacebar, and bigger, clearer action buttons. - Opening several selected photos now scopes the viewer to just that selection. - Removable drives get a one-click eject button in the sidebar. - Faster perceived RAW loading, with no more staring at the previous photo while a RAW decodes. - Dozens of smaller fixes, including a bug where thumbnails could permanently vanish from the browser for certain photos.
