Core Updates#

1. New Features

   • [Web Client] Added initial device flyover tour on the solo map: on first page entry, the map flies over valid GPS devices one by one, dwelling on each for about one second; any map operation immediately takes over and ends the tour.
   • [Web Client] Device group-join notification adds group name, sample rate and audio encoding fields, so devices obtain the complete group audio configuration upon joining a group.

2. Feature Optimization

   • [Web Client] Overall optimization of intercom UI text and status presentation: business language replaces protocol jargon and internal identifiers; connection failures are now presented categorized by source (timeout, service communication, session confirmation, audio, call settings); wording for online count, reference capacity, audio preset naming, etc. is calibrated; multilingual text completed and consolidated.
   • [Web Client] Performance optimization for large-scale device scenarios: the multi-stream live view device tree, solo map markers and global UI rendering are significantly lightened at the 500-device scale, with smoother operation and input response.
   • [Web Client] Location and address query results are persistently cached locally, making map positioning and country/reverse address lookups faster; cached results remain usable on weak networks.
   • [Web Client] Report log queries switched to month/day partitioned retrieval with merged sorting, making queries over large time ranges more stable, with scroll loading support.
   • [Web Client] Excel import/export entries on report pages unified; the Excel component now loads on demand, making pages open faster.
   • [Web Client] Map fly animation arrival is now determined by the actual landing point, and the animation is safely cancelled when switching targets or leaving the page, making positioning flights more precise and stable.
   • [Web Client] Intercom signaling handling consolidated; late or irrelevant replies no longer incorrectly advance room state, making room entry and configuration flows more reliable.
   • [Web Client] Form error messages and intercom status text are uniformly translated at the presentation layer, making multilingual presentation more complete and accurate.
   • [Web Client] The captcha automatically refreshes after a failed login, with no manual replacement needed.
   • [Backend] Optimized database connection pool configuration and idle recycling strategy, reducing resident and peak resource usage; connection lifecycle management is more reliable and better suited to small-spec server deployments.
   • [Backend] Display and recomputation of tree data such as organizations, tenants, user groups and device categories are uniformly consolidated, automatically correcting duplicate nodes and broken relationship loops, making hierarchical display more reliable.

3. Bug Fixes

   • [Web Client] Fixed intercom member list still showing stale online status after a device goes offline.
   • [Web Client] Fixed feature failures caused by incorrect request parameter formats for device room-entry compensation and PTT configuration delivery.
   • [Backend] Restored legacy compatibility for authentication and permission error responses of existing clients (HTTP 200 transport with the original error codes and messages), preventing legacy devices and the Web client from failing to authenticate.
   • [Backend] Fixed noticeable audio delay in intercom speaking (room creation audio parameters optimized based on field integration feedback).
   • [Backend] Fixed initialization flow failures caused by missing message tenant scope in the first administrator login scenario.
   • [Backend] Added the missing Janus management page entry and configuration update permission for the team management default role; roles initialized from the template can directly enter the page to edit configuration.
   • [Backend] Fixed data consistency issues during device ownership transfer; transfers are finalized as an atomic transaction, eliminating half-transferred states.
   • [Backend] Fixed callback exceptions after transaction commit causing already-successful operations to be falsely reported as failed.
   • [Backend] Fixed operation logs missing in transactional scenarios, making audit log records more complete.
   • [Backend] Unified the determination and query condition source of the 'created by me only' data permission; client-supplied permission fields are no longer trusted, preventing unauthorized queries.

4. Policy Adjustment

   • [Backend] PTT default intercom group mechanism adjusted: the platform no longer maintains the default group flag on device-group relationships; the default group is now retained on the device side, and when a change is needed, the current default group is explicitly delivered per single device from the management interface. The PTT configuration refresh and query contracts are updated accordingly — the configuration refresh request can carry the current default group, and the device query returns the currently selected default group together with the complete group list (the default flag field is no longer returned), with group-join notification fields adjusted in sync. Access endpoints still reading the default flag field or the legacy refresh payload should complete their adaptation.

Core Updates#

1. New Features

   • [Web Client] Added intercom group device request-to-leave functionality: initiate a request-to-leave for in-room devices from the member list; after confirmation, a request-to-leave notification is delivered and it waits for the device to leave.
   • [Web Client] Added microphone level segmented bar and speaking status ring, visualizing speech volume and transmission status in real time, with animations rising and falling with the volume.
   • [Web Client] Added automatic collection and batch reporting of missing UI translations, automatically sending missing entries back to improve multilingual completeness.
   • [Backend] Added BMC device binding lifecycle query, returning binding lifecycle fields and supporting filtering by creation/modification/deletion time ranges.

2. Feature Optimization

   • [Web Client] Intercom room entry acceleration: streamlined signaling interactions and parallelized room entry steps, significantly reducing room entry time; ICE configuration cached locally, making room entry more stable on weak networks.
   • [Web Client] Optimized error message presentation: business failure messages accurately presented locally and internationalized, eliminating duplicate global and local notifications.
   • [Web Client] UI text standardization: unified casing and terminology spelling, bringing existing hardcoded text into multilingual management.
   • [Web Client] Intercom group editor added a leave confirmation prompt, preventing unsaved configuration loss from accidental refresh or tab closure.
   • [Web Client] Added English-version build profiles and mistake-proofing for version information injection, supporting international edition deployment and release. ❓ (Build capability for international edition deployment with no direct visibility for domestic integrators — pending decision on whether to include)
   • [Backend] Multi-tenant write boundary hardening: write operations across employees, organizations, dictionaries, permissions, messages, translations and other domains uniformly receive the tenant from the server side, preventing unauthorized cross-tenant data writes.
   • [Backend] Security hardening: uploaded file path containment, sensitive log masking, strict validation of Janus upstream messages, and tenant boundaries for Janus server management.
   • [Backend] Protocol error response standardization: parameter validation failures, request method/media type mismatches, missing resources, etc. now uniformly return 4xx instead of falling into 500, making it easier to handle errors by status code.
   • [Backend] Optimized device online status determination; client activity events immediately refresh online status, preventing devices from being incorrectly marked offline.
   • [Backend] Unified tenant context assembly across the four login entry points, making tenant restoration behavior consistent after login from any entry point.
   • [Backend] Dictionary query supports business-tenant custom entries overriding public defaults.

3. Bug Fixes

   • [Web Client] Fixed live view freezing for extended periods during device P2P transition states, and improved signaling message delivery reliability.
   • [Web Client] Fixed report menu not displaying under certain role combinations; permission-related UI is hidden immediately after account deactivation.
   • [Web Client] Fixed page entry incorrectly blocked due to intercom group read permission determination being inconsistent with backend permission identifiers.
   • [Backend] Fixed legacy WebRTC firmware devices getting no response when retrieving ICE configuration (webrtc topic replies disappearing).
   • [Backend] Fixed device list and detail interfaces missing the binding authorization code field.
   • [Backend] Fixed platform-side simulated retrieval incorrectly marking disconnected devices as online.
   • [Backend] Fixed device message handling failures causing duplicate response sending or echoing internal exceptions back to devices.
   • [Backend] Fixed database snapshot triggers failing to create history tables or incorrectly deleting cross-tenant history data in abnormal scenarios.
   • [Backend] Fixed duplicate consumption caused by message loops between Janus forwarding and retrieval responses.
   • [Backend] Fixed All-family semantics in permission determination (previously any matching permission granted access); multi-permission combination validation restored to strict matching.
   • [Backend] Fixed the generic firmware save interface binaryHeader field losing its object structure.
   • [Backend] Fixed imprecise verification email translation matching, so the verification emails received by multi-language users now match their interface language.
   • [Backend] Fixed role updates being able to overwrite the built-in administrator role, preventing the built-in administrator role from being modified and the permission system from failing.

4. Policy Adjustment

   • [Backend] Retired deprecated public interfaces (cache read/write, intercom group counting); if still in use, please migrate to the replacement interfaces.
   • [Backend] Retired legacy MQTT channel families (the server/center/ prefixed channel family and the legacy Web UI Janus forwarding channel); the transition period has ended, and access endpoints still using legacy channels should complete the switch.
   • [Web Client] WebRTC status event topic unified to the canonical format device/{deviceNo}/webrtc/status. ❓ (Internal event topic migrated in sync across frontend and backend; uncertain whether it constitutes a contract commitment to integrators — pending decision on inclusion)
