rtpengine
rtpengine backports the same DTLS and socket fixes across four maintenance branches at once.
A side-by-side editorial comparison of JW Player and OpenSIPS — release velocity, themes, recent moves, and the top alternatives to consider.
JW Player is rebuilding its VOD pipeline around CMAF, one workflow fix at a time
JW Player's releases split between the CMAF VOD pipeline (automatic renditions, duration-scaled seek thumbnails, in-place source re-uploads) and player and SDK work on captions, accessibility, casting and display options. The latest entry makes Motion Thumbnails a per-player setting. Ad-serving analytics gained content and placement dimensions twice in six weeks.
OpenSIPS 4.0 is in release-candidate testing, with two RCs a month apart.
OpenSIPS, the open-source SIP proxy and server, has two tracked entries: 4.0.0-rc1 in May and 4.0.0-rc2 in June 2026. Both release notes are one-line announcements, so the specific 4.0 changes are not visible in the feed.

The latest entry makes Motion Thumbnails a per-player setting. Ad-serving analytics gained content and placement dimensions twice in six weeks.
The CMAF workflow is being brought to parity with the legacy pipeline feature by feature, which points to a migration of publishers onto it. In parallel, player UX settings, SDKs and analytics are tuned for publishers who monetize through ads and need fine control over how players present content.
More CMAF VOD parity features are the likeliest next releases, possibly followed by a deprecation notice for the older pipeline; the entries don't yet signal a date.
OpenSIPS, the open-source SIP proxy and server, has two tracked entries: 4.0.0-rc1 in May and 4.0.0-rc2 in June 2026. Both release notes are one-line announcements, so the specific 4.0 changes are not visible in the feed.
The product is moving toward a 4.0 major release through a standard RC cycle. A second RC a month after the first suggests stabilization work rather than new scope, but the entries do not say what 4.0 changes.
A 4.0.0 general release is the next expected step; what it contains cannot be read from these announcements.
