SDK changelog

Every SDK release. /sdk/v1/<file> always serves the latest; /sdk/v<version>/<file> serves exactly that release, cached for a year, and the hashes below pin it with Subresource Integrity.

1.0.0-alpha.22

• SeatPreevue.show(document.body, seat) now opens the view in Seat Preevue's own dialog: a modal with a close button (Escape and a click outside also close it), a loading state, "No view for this seat yet." when there's none, and "Try again" when it fails. In the dialog, show() never rejects; the unavailable and error events still fire. Pass { inline: false } to use the dialog for any target. Unchanged: show(element, seat) still draws inside your element, as { inline: true } always does.
• New: SeatPreevue.previewUrl(seat) (the seat's signed preview image, or null), SeatPreevue.isAvailable(seat) (true when our manifest lists a view for the seat) and SeatPreevue.resolveSeatKey(tokens) ({ key, candidates, matched }). "No view" is an answer, never an error; they share one request with a later show() of the same seat.
• New init() options: locale (a language tag such as cy-GB, for the words the SDK shows) and onReady(session), called once the session is ready.
• An ES module build of the SDK: seatpreevue-core-esm.js, with the same names as window.SeatPreevue as named exports.
• Views keep working however long they stay open: the SDK renews its access every 15 minutes, and a view whose images stop loading, or that's touched after a computer wakes from sleep, renews and redraws itself at the same position.
• The Criterion script's dialog and the hosted embed's messages use the words the session carries, so they can follow the venue's language.

1.0.0-alpha.21

• The Spektrix script needs one URL and no flags: https://assets.seatpreevue.com/sdk/v1/seatpreevue-spektrix.js, in your page header and in the new Seat Picker's view-from-seat setting. In the header it starts as the page loads and hides the Seat Picker's view button wherever the space, or that seating plan, has no views. On the old seating plan, on pages without a picker, or when the Seat Picker loads it on a click, it behaves exactly as before.
• We can switch that start-up check off for a space from our side, with nothing for you to change; the button then shows as the Seat Picker made it.

1.0.0-alpha.20

• New: SeatPreevue.track(event, props) lets your page report a conversion (seat_selected, seat_added or checkout_reached), sent with the viewer's other events. Pass ids and codes only, never personal data: values that look personal are dropped.

1.0.0-alpha.19

• The old Spektrix seating plan's view window is now a proper modal dialog: it's announced to screen readers by name, takes focus when it opens, keeps it inside while open, and returns it to the seat when it closes.
• The Viadukt script's view is reachable by keyboard and labelled for screen readers.

1.0.0-alpha.18

• Smaller fixes to the viewer's first open: the stylesheet is applied before the view is sized, in every case.

1.0.0-alpha.17

• A new, opt-in way for the Spektrix script to start: it can check, as the page loads, whether the space has views, and hide the Seat Picker's view button where there are none. Off unless the script URL asks for it; nothing else changes.

1.0.0-alpha.16

• Dragging the view works on every page: the viewer's input layer can no longer be hidden by a page's own styles.

1.0.0-alpha.15

• Spektrix's new Seat Picker: a seat in a space that has no views now says "Seat views aren't available for this space." (information, not an error, so no "Try again").

1.0.0-alpha.14

• The view no longer opens zoomed in the first time: the viewer waits for its stylesheet and the final layout, and resizes when it's shown.

1.0.0-alpha.13

• Spektrix's new Seat Picker: the view window closes on a click outside only when the press started outside it (so dragging the view to its edge no longer closes it).

1.0.0-alpha.12

• New: seatpreevue-viadukt.js, for Viadukt sites (Viadukt).

1.0.0-alpha.11

• New: seatpreevue-criterion.js, for Criterion booking sites (Criterion).

1.0.0-alpha.10

• Spektrix's new Seat Picker: closing the view returns focus to the seat, reliably.

1.0.0-alpha.9

• Spektrix's new Seat Picker: focus returns to the seat when the page had nothing focused before the view opened.

1.0.0-alpha.8

• Spektrix's new Seat Picker: a seat in a venue we don't know yet says "No view for this seat yet." instead of an error; closing the view returns focus to the seat.

1.0.0-alpha.7

• New: the hosted view, /embed/v1/ (The hosted view): a page for an <iframe>, with messages to the page around it.

1.0.0-alpha.6

• New: seatpreevue-tnew.js, for Tessitura TNEW sites (TNEW).

1.0.0-alpha.5

• Security hardening: the viewer accepts only the configuration fields it needs, every script and stylesheet it loads is pinned with Subresource Integrity, and errors are never cached.

1.0.0-alpha.4

• New: seatpreevue-legacy-shim.js, which keeps initSeatPreevue(…) working on v1 and falls back to the old way while a venue isn't on v1 yet (the shim).

1.0.0-alpha.3

• New: seatpreevue-spektrix.js, for Spektrix's old seating plan and new Seat Picker, keyless or with a key (Spektrix).
• The core can show adverts in the view for venues that have them.

1.0.0-alpha.2

• The viewer's stylesheet is served from our assets host with the release, pinned with Subresource Integrity.

1.0.0-alpha.1

• The first release of the core (seatpreevue-core.js): sessions (keyless or with a key), seat resolution, showing a seat's 360° view in your element with signed imagery, and events.
