# Version 2.2.0

### v2.2.0 30-July-2026

**Added**

1. **360° Virtual Tour (Pano) APIs.** New read APIs serve navigable 360° panoramic tours built from your maps. List pano-enabled maps, fetch a viewer-ready manifest of every node, or request a local navigation "window" around a node or a world position. Including continuous tours that span map versions and MapSets. [360° Virtual Tour (Pano)](/multiset/basics/rest-api-docs/pano-360-virtual-tour.md)
2. **Camera Intrinsics API.** Estimate a camera's intrinsic parameters (focal length and principal point) from one to five images, with an optional lens-distortion model. Useful as a prior when calibration data isn't available. [Camera Intrinsics](/multiset/basics/rest-api-docs/camera-intrinsics.md)
3. **Map Scale API.** Apply a metric scale factor to a standalone 360 (Insta360) map to correct its real-world scale. Runs asynchronously and updates the map in place. [Map Scale](/multiset/basics/rest-api-docs/map-scale.md)
4. **Object upload as a zip package.** Object (3D model) uploads are now packaged and uploaded as a `.zip`, aligning the object upload flow with map uploads. [Object Upload](/multiset/basics/rest-api-docs/modelset-upload.md)
5. **Resumable large-map uploads.** Large map uploads can now be paused and resumed instead of restarting from scratch. Create the map with `?resumable=true`, and if an upload is interrupted you can list the parts already uploaded, request fresh signed URLs for the remaining parts, and complete the upload, or abort it cleanly. Ideal for large scans on slow or unstable connections. [Map Upload](/multiset/basics/rest-api-docs/map-upload.md)

**Fixed**

1. **Faster, more accurate multi-frame query.** The multi-frame query is now more accurate and up to 50% faster. [Map Query](/multiset/basics/rest-api-docs/map-query.md)
2. More reliable large-file map uploads: interrupted multipart uploads no longer have to be restarted from the beginning. [Map Upload](/multiset/basics/rest-api-docs/map-upload.md)

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://multiset.gitbook.io/multiset/quick-access/changelog/version-2.2.0.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
