Improved audio decoder stability. - Improved coded packet handling with single-path receive. - Coded receive path B max jitter statistic now displays correctly. - Data channel decoder "Tx bytes" statistic now counts correctly. ## 1.3.0-6-rc ### New Features & Enhancements - Statistics page now refreshes automatically. - Reduced internal latency. - Web UI access can be enabled on more than 3 Ethernet interfaces using the IFACE_WEBUI_HTTP environment variable. - Ping and traceroute utilities in the Web UI, which can run at the same time. - Improved licensing user interface. - Statistics for data channels on the Web page. - Automatic log rotation. - Multiple data channels on a single decoder. - Setting to configure the number of active codec slots. - PTP two-step operation support. - Codec slot receive buffer extended to support up to 20 seconds. - New "Minimal Jitter Buffer Fill" field on the Web statistics page. - 8 MODI instances included with the base license. - Dynamic network interface support: IP address changes on Ethernet interfaces are detected and applied to Web access automatically. - Ethernet port status changes (link up/down, IP address changes) are now written to the start log. - Background process health monitoring for improved long-term reliability. - Warning on the AoIP and Options pages when the TAI/UTC time offset is not configured. - Quick-start guide updated with Reverse Path Filtering configuration. - Removed the User Manual link from the Web UI. ### Improvements & Fixes - Improved audio high-frequency response for all codecs. - Improved audio quality for AAC-HE at 24 kbps in Dual Mono. - Reduced CPU usage for AAC-LC and aptX encoders at 32 kHz sample rate. - Improved AAC-LD decoder reliability, including when receiving AAC-LD over TCP. - Decoder continues running when encoder settings are changed. - Decoded audio continues smoothly during synchronization changes. - Improved decoder handling when an incoming stream changes from a 32 kHz codec to No Audio (GPIO only). - Decoders no longer report lost samples when receiving No Audio (GPIO only) streams. - Improved stream recovery after network link changes. - Improved Sample Rate Converter stabilization. - AES67 stream timestamps now correctly account for the TAI/UTC offset. - AES67 synchronization mode selection now works as expected. - Improved synchronization stability when a PowerStation set to clock priority 3 joins the network. - Improved data channel message delivery, including with No Audio decoders and Content Delay, and on codecs 2–8. - Improved data channel configuration reliability. - Stream statistics now display jitter values correctly. - GPIO messages now work with all receive buffer sizes when Content Delay is enabled. - Content Delay playback offset can now be set below 2 minutes. - Improved Content Delay storage maintenance. - Input validation prevents incompatible Receive Buffer and Playback Offset settings. - Codec input/output states are kept when the effective codec count changes. - Decoders keep their previous settings after a license is removed and reactivated. - Licenses remain visible in the Web UI without an internet connection. - Improved license service communication. - Configuration backup/restore now includes all receive buffer and internal jitter buffer settings. - Improved configuration restore/reset reliability. - Internal jitter buffer size defaults to 35 ms if not set. - MODI output streams resume correctly after a restart, with improved MODI audio processing. - MIXI outputs are available in the MODI input selector. - LW backfeed channels now appear in the advertisement list. - V-mode unicast port numbers are validated when configured through LWRP. - LWRP DST now reports the correct address for each path. - LWRP logins are accepted once the service is fully started. - Improved LWCP message handling robustness. - Improved syslog stream event messages. - Improved Web access when the interface uses DHCP or has multiple IP addresses. - Improved long-term container health reporting. - Improved stability when enabling/disabling decoders. - iProbe now shows only the correct update packages. - Removed the restart button from the software update page. - Added info text to the network info page. - Decoder bitrate change notifications are reported only when needed. - Removed unnecessary warnings at container start-up and for the http/https option. - Web UI text and cosmetic improvements. ## 1.1.0 ### New Features & Enhancements - Product name updated to Telos Zephyr Connect. - vMix and vMode renamed to MIXI and MODI. - Phase inverter and Pan controls on each of the 5 inputs of every MIXI. - Docker image based on Ubuntu 22.04 LTS. - Codec slot receive buffer increased to 10,000 ms in user-defined increments. - TCP streams now survive connection interruptions of up to 9 seconds, with improved TCP receive performance. - Codec channel enabled status and configuration are kept through license renewal, removal, and restoration. - Transit Points accept the full port range. - Web access configured using the IFACE_WEBUI_HTTP environment variable. - Field names added to SRC/DST status and Audio indications on the Codecs Web page. - Ping utility added to the container. - Updated licensing component. - Updated User Manual link. - Smaller container image with unused libraries removed. ### Improvements & Fixes - General stability improvements. - Improved license persistence. - Improved Content Delay audio when the far-end encoder type or the stream sample rate changes, and after license restoration. - Improved decoder initialization with silent or sine-wave input. - Coded streams are received independently of the host's NTP synchronization. - Improved timestamp correction precision in synchronization. - Improved AES67/LW output stream timestamp accuracy. - AES67 RTP stream signaling now includes both GMID and PTP domain. - SDP TTL value now matches the RTP packets. - Multicast traffic is now kept on the correct network interface. - Improved LW/AES67 stream receiver robustness. - MODI instances switch to AES67 correctly. - MODI output configuration changes are applied smoothly. - MIXI phase uses the correct default value. - GPIO configuration sent through LWRP is saved. - Improved input source configuration reliability. - LWRP MTR level reporting improvements, including inactive decoder outputs. - MTR ICH accepts all meter channels. - LW input stream statistics session counter now updates. - SNMP trap uptime matches the Web UI system time. - Web server starts reliably after a cold boot and when WAN access is disabled. - Status page now displays Content Delay license info correctly. - Syslog and Web UI cosmetic improvements. ## 1.0.0 - Initial release.
