name: WorldViz Lifecycle and Versioning
description: >-
  Versioning, breaking-change and support posture for WorldViz's developer surface. WorldViz
  ships desktop software (Vizard, SightLab VR Pro, Vizible) rather than a hosted API, so the
  lifecycle signals that exist are product-release signals: a version scheme, a documented
  upgrade/breaking-change guide, per-version archived documentation, and paid support tiers.
  There is no hosted service, therefore no status page, no SLA and no API deprecation policy.
subject: Vizard VR development toolkit (desktop software)
versioning:
  scheme: MAJOR.MINOR[.PATCH]
  current: 8.3.1
  documented_at: https://docs.worldviz.com/vizard/latest/highlights.htm
  in_url: true
  note: >-
    Documentation is versioned by URL path — docs.worldviz.com/vizard/<version>/ — with
    /vizard/latest/ aliasing the current release. Every archived build back to 3.18.0002 is
    still served.
breaking_changes:
  documented: true
  url: https://docs.worldviz.com/vizard/latest/Upgrade_guide.htm
  http_status: 200
  most_recent:
    version: '8.0'
    date: '2024-11-11'
    changes:
    - Bundled Python moved from 3.8 to 3.13
    - Minimum OS raised to Windows 10
    - PIL/Pillow unbundled; install via the Package Manager
  note: >-
    WorldViz publishes an upgrade guide naming what breaks between major versions. It names
    the runtime and platform changes but does not enumerate deprecated or removed commands by
    name, so a script author cannot mechanically diff their code against it.
deprecation_policy:
  published: false
  sunset_headers: false
  note: >-
    No deprecation policy, no sunset schedule, no RFC 8594 Sunset/Deprecation headers — there
    is no HTTP surface to carry them. The upgrade guide is a breaking-change narrative, not a
    deprecation policy, so no `Deprecation` pointer is emitted.
status_page:
  published: false
  probed:
  - url: https://status.worldviz.com/
    status: 000
    note: DNS does not resolve.
  note: >-
    No status page. WorldViz operates no hosted API or tenant service whose availability
    would be reported, so no `StatusPage` pointer is emitted.
sla:
  published: false
  note: No published uptime or response-time SLA.
