• #34554 Supported the conversion of already set deprecated streamer_hostname to the required tag for backward compatibility.
• #34612 Supported the conversion of streamer_hostname in a newly created/updated/deleted stream to the required tag to allow the use of streamer hostname by Watcher until switching to tags.
• #34706 When Central is installed with Watcher, the default password for accessing Central Admin UI is now generated randomly to ensure security; the previously set default password is replaced with a randomly generated one at update to Watcher 23.12 or later. You can check and change the password in the /etc/central/central.conf config file. Note that the password you set in the EDIT_AUTH environment variable will not be affected.

Improved

• #34187 Improved GET /streams/{name}/layouts request to support cursor, limit, and filtering by layout creation date.
• #34743 Improved the display of the status of connection between Central and vision or identification nodes with a green indicator and the number of provisioned streams.

• #34719 Fixed the issue with stream tags disappearing after Central restart.
• #34733 Supported _is_null and _is_not_null filters for the fingerprint field to filter out the episodes generated by the old analytics module that are not supported by the identification service.
• #34790 The cluster_key parameter is no longer required for streamers with vision and identification types because analytics nodes do not have cluster keys.

• #34836 Fixed the issue with thumbnail_quality parameter taking values greater than one in the responses from Central while the schema states the range of [0..1]. The episodes with invalid values will not be returned any more.
• #35245 Fixed the issue with disconnecting agents from the Central.

New

• #27152 (Flussonic) Supported the use of ?filter.tracks parameter with LL-HLS playback URLs (/index.ll.m3u8). You can use it to filter only the tracks that are required on the end-user’s device (for example, you may not want to deliver 360p to TVs or 4K to mobile devices).
