New release v4.1.1, RC-1 with Build 2026092501 is ready. 

Here are the list of changes;

- Management API v2. Integrations authenticate with an API key and a signed request instead of a user session, address fields by name, discover the actions of every record from the response itself, and get a reason code with every failure. Version 1 keeps working unchanged. The core guide, the hospitality, CPE and blind-scan addenda and the reference clients are published on GitHub.

- DVB Carrier Monitor. A new product: an appliance fitted with TBS DVB-S/S2 cards that acquires the spectrum of an input, blind-tunes every carrier it finds and reports the tuning parameters and programme tables of each transponder. Delivered as the external module "DVB Blind Scan" (stabsc) for appliances on the 6.18.7-1 kernel.

- Encrypted HLS as a source. The headend's own HLS input plays AES-128 encrypted playlists, with key rotation, so an encrypted output of one headend can feed another.

- Output audit. For every output, one minute of per-second figures for bitrate, PCR interval and accuracy, delivery timing, null packets and continuity, shown as sparklines on the status page next to each stream and flagged when a figure leaves its limits. The same figures reach integrations through the stream information export.

- Smoother transcoded outputs. A "Module Buffering" setting gives transcoded and pre-processed outputs their own delivery buffer, separate from the global one, so they leave the headend as evenly as relayed streams.

- Runaway protection for external modules. A memory limit per module process, 2 GB by default, restarts a module that outgrows it and logs the event, so one misbehaving source can no longer exhaust the unit.

- Direct playback in the media portal. Besides HLS, the media portal can play transcoded outputs directly as MPEG-TS in a desktop or Android browser, with one to two seconds of latency, and hands the whole list to VLC with one button.

- Status page for the road. Full Details, Output Audit, Live Feed and a refresh interval of 1.5, 5 or 15 seconds as buttons on the streaming dashboard.

Kylone v4.1.0 is ready as RC-1 with Build 2026091802.

Here are the list of changes;

- Integration feeds: A discoverable feeds tree prepared for LG/Samsung (hospitality) platforms.

- HLS for hospitality. Multi-audio publishing modes, independent segments, keyframe-aligned chunks, and a "Hospitality TV" template that sets the codec, GOP and audio parameters TVs and HTML5 players expect.

- Subtitles on HLS: WebVTT support with language and name in the playlist; DVB bitmap subtitles can still be burnt in.

- Captions module: A new pre-processing module, bitmap subtitles (OCR) or from the speech on the audio track, in the spoken language, translated to English, or both. Speech captions are assistive captions and follow the dialogue with a short delay (6 seeconds).

- Encrypted HLS: AES-128 encryption support with keys the headend serves itself, with no DRM contract. Keys are handed only to devices the headend's peer policy allows or to applications presenting an HLS API key. Key rotation from the web UI or on a schedule without interrupting viewers.

- HTTPS-TS: The unicast HTTP-TS service can run over TLS with the same certificate the web UI uses.

- VLC-playlist for admins: Every tier and protocol of a channel opens in VLC from the Output URLs page with one click.

- Playout fixes. Looping file channels with subtitle or teletext tracks play out at a steady rate through the loop.

New release candidate RC-3 for v4.0.0 with Build 2026090102 is ready. We have some fixes and improvements in this release.

- SCTE-35 support

New release candidate RC-2 for v4.0.0 with Build 2026082401 is ready. We have some fixes and new features, here is the list;

- SCTE-35 DPI is implemented.
- SRT listener improved, multi-worker implemented to utilise more CPU cores. Number of workers can be configured from the web-ui. 
- HLS, M3U/playlist import/scan issue is fixed.
- RKOS installation issue is fixed.

The new RC-1 for major release v4.0.0 with Build 2026081620 is ready.

Herer are new features and improvements on this release;

- RTSP server improvements (Basic/Digest Authentication support added)
- Stand-In feature is fully implemented, covering scheduled park/es-graft and automatic backup-1:1/backup-1:N options.
- Stream URL's page improved to show all possible options covering Stand-In features.
- Several fixes and improvements related to core-library's v4.0 major update.

The "Stand-In” feature is; automatic, scheduled or on-demand source substitution for protected channels (1:1 and 1:N, with optional fallback), with a stable output identity so receivers never re-scan.

- Parking — hold a channel on your own filler feed for a scheduled window and return it automatically, without receivers re-scanning.
- Backup - A protected channel switches to its Stand-In source automatically the moment its own source stops, and returns on its own once the source is healthy again. No operator action in either direction.
- Fallback - A second source behind the Stand-In source. If the Stand-In itself is unavailable when it's needed, the fallback takes the slot instead, so a single dead source can't leave the channel dark.
- Guard - Watches the channel after a switch has happened. If the source currently on air goes quiet, Guard moves the channel on — to the fallback where one is defined — rather than leaving it stuck on a dead feed.
- Scheduled switching - Run any Stand-In switch from the clock: once at a given time, or daily at a fixed window. The channel returns to its own source at the end of the window automatically.
- One-to-many A single source can cover any number of protected channels at the same time, each keeping its own service identity on air. Useful for a house filler or an announcement feed during a site-wide event.
- Audio substitution (ES graft) - Replace only the audio of a protected channel, keeping its own video — across one channel or many at once, with the substituted audio time-aligned per channel. For alternate-language or commentary feeds.
- Stable output identity - Every Stand-In mode keeps the output's service ID, PMT and ES PIDs fixed across a switch. Modulated DVB-C receivers and STBs never re-scan.
