NEW FEATURES
General Features
- AI Manager is added as a plugin. See more at https://www.networkoptix.com/nx-ai-manager.
Server HTTP API
Virtual Device Uploads (VMS-60188)
- Added new chunk-based upload endpoints for virtual cameras in v4, replacing the deprecated
legacy /api/downloads/... API:
- GET /rest/v4/devices/{deviceId}/virtual/uploads: list active uploads for a virtual device.
- POST /rest/v4/devices/{deviceId}/virtual/uploads: initiate one or more file uploads, providing
file metadata (startTimeMs, durationMs, sizeB, md5, container, codec). Returns upload session
details including uploadId, chunkSizeB, and fileId.
- GET /rest/v4/devices/{deviceId}/virtual/uploads/{uploadId}: get upload status including
uploadProgressPercent and archiveProgressPercent.
- PUT /rest/v4/devices/{deviceId}/virtual/uploads/{uploadId}: upload a data chunk for an
in-progress upload.
- DELETE /rest/v4/devices/{deviceId}/virtual/uploads/{uploadId}: cancel an in-progress upload.
Per-Item ETags for Resource Endpoints (VMS-60867)
- Added etag field to individual resource responses across v1–v4. This enables external systems
to check per-resource consistency without retrieving full collections. Affected resource types:
devices, event rules, layouts, layout tours (v1) / showreels (v2+), lookup lists, servers,
user groups, users, video walls, and web pages.
Server Plugin SDK
Vectorization Model Discovery (VMS-59576)
- New IUtilityProvider6::supportedVectorizationModels() method returns a comma-separated list
of supported image/text vectorization model names (e.g., "openai/clip-vit-large-patch14-336").
Plugins can specify a vectorization model from this list in the EngineManifest and use it to
generate and attach a vector to the track's best shot data.
Server Data Directory Access (VMS-60205)
- New IUtilityProvider::dataDir() method (IUtilityProvider7) returns the absolute path to the
Server's Data Directory, or an empty string if it is absent.

IMPROVEMENTS
Server HTTP API
Server Configuration
- /rest/v{1-4}/servers endpoints: added loginLabel field to portForwardingConfigurations
items, providing a custom label for the login field in UI.
Site Settings (VMS-61136)
- GET /rest/v4/site/settings and PATCH /rest/v4/site/settings: added mediaSendTimeoutS
setting to configure the socket send timeout for HTTP media streaming.
Authentication (VMS-60717)
- POST /rest/v{3-4}/login/tickets: removed incorrect _strict and _ticket query parameters
from the endpoint schema.
Site Discovery (VMS-60742)
- GET /rest/v{1-4}/site/other (and system/other in v1–v2): added _ticket query parameter.
Analytics Integrations (VMS-61073)
- DELETE /rest/v4/analytics/integrations/{id}: endpoint is now fully functional and can be used
to remove SDK integrations from the Server.
Showreels / Layout Tours (VMS-61201)
- GET /rest/v4/showreels (and layoutTours in v1): the collection now returns all showreels to
Power Users, not only those owned by the requesting user.
Cloud Service Permissions (VMS-60027)
- Cloud Service User can now read and subscribe to rest.v4.events.rules and
rest.v4.lookupLists endpoints (previously required Power User permissions).
Server Security
- (VMS-61139) Default HTTP Server response header changed from Apache-style identification to
{vmsName}/{vmsVersion}, eliminating false-positive Apache vulnerability alerts in security
scanners.
- (VMS-61202) TLS v1.1 removed from the list of supported TLS versions by default. Clients that
relied on TLS 1.1 must upgrade to TLS 1.2 or later.
- (VMS-61046) ECDSA certificates (e.g., from Let's Encrypt) are now accepted for server HTTPS.
Previously, loading an ECDSA-based cer
