What is Asterisk?

Four parallel branches, one fix set — Asterisk's changelog is a backport ledger, not a feature list.

Asterisk maintains mainline 20, 22 and 23 branches alongside a certified track, and lands each fix set across all of them at once. The June 25 batch was a coordinated security release resolving roughly 20 advisories on every branch simultaneously. The August 7 batch opens the next cycle with release candidates carrying identical commit, author and issue counts across 23.5.0, 22.11.0 and 20.21.0.

What is mediasoup?

mediasoup has moved off data-channel plumbing and into the media path — timing first, now layer selection.

The Rust line spent most of this window on single-PR point releases, nearly all of them subchannel plumbing for DataConsumers over pipe transports plus the occasional crash fix. That pattern broke with 0.26.0, a seven-PR reworking of how RTCP Sender Reports are generated, moving them off RTP packet arrival time and onto an estimate of when media was captured. 0.27.0 continues in the media path with a breaking change limiting simulcast and SVC to the preferred temporal layer. The 0.24.0 release earlier in the window also carried real security work — constant-time MAC comparison plus fixes for an OOB write and an SCTP integer overflow.

Asterisk vs mediasoup: editorial side-by-side

A
Asterisk
MEETINGS
5.0

Four parallel branches, one fix set — Asterisk's changelog is a backport ledger, not a feature list.

◆ Current state

Asterisk maintains mainline 20, 22 and 23 branches alongside a certified track, and lands each fix set across all of them at once. The June 25 batch was a coordinated security release resolving roughly 20 advisories on every branch simultaneously. The August 7 batch opens the next cycle with release candidates carrying identical commit, author and issue counts across 23.5.0, 22.11.0 and 20.21.0.

◆ Where it's heading

The visible output is backport discipline rather than feature development. Release notes carry counts, tags and advisory IDs but no feature text, so the changelog reads as a stability and security ledger for a mature telephony core. The certified track deliberately lags mainline and picks up a smaller subset of each cycle.

◆ Prediction

The three release candidates should promote to final within the project's usual short RC window, with the certified branch taking the same fixes a cycle later. Nothing in these entries points to feature work in flight.

6.3

mediasoup has moved off data-channel plumbing and into the media path — timing first, now layer selection.

◆ Current state

The Rust line spent most of this window on single-PR point releases, nearly all of them subchannel plumbing for DataConsumers over pipe transports plus the occasional crash fix. That pattern broke with 0.26.0, a seven-PR reworking of how RTCP Sender Reports are generated, moving them off RTP packet arrival time and onto an estimate of when media was captured. 0.27.0 continues in the media path with a breaking change limiting simulcast and SVC to the preferred temporal layer. The 0.24.0 release earlier in the window also carried real security work — constant-time MAC comparison plus fixes for an OOB write and an SCTP integer overflow.

◆ Where it's heading

The subchannel thread that dominated July has gone quiet and the media path has taken over. First timing correctness — RemoteClockOffsetEstimator and RemoteCaptureTimeEstimator gave the worker a notion of remote capture instants it did not previously have — and now layer selection, with 0.27.0 constraining which temporal layer simulcast and SVC will actually deliver. Both are behavior changes in what an SFU sends downstream rather than additions to its API surface, and 0.27.0 is labelled breaking, so integrators are being asked to absorb them.

◆ Prediction

With two consecutive releases changing media-path behavior, the near-term releases are likely to be corrections shaking out the new timing and layer-selection paths across simulcast and pipe transports. The capture-time estimators remain unused beyond Sender Reports, which leaves them the obvious foundation for further synchronization work.
