Synapse vs Whereby: at a glance
What is Synapse?
Synapse 1.164 advertises Matrix v1.16 and v1.17 amid a run of dependency security patches
Synapse keeps its two-to-three-week cycle of candidates and stables. 1.164.0 went stable on 27 October with support for Matrix v1.16 and v1.17 and a dedicated endpoint for scheduling delayed events (MSC4140). The surrounding releases are security dependency bumps: certifi, a rustls-webpki update that distrusts the compromised eMudhra intermediate CAs, Pillow 13.0.0 for critical image-handling flaws, and msgpack against memory exhaustion on the public room list.
What is Whereby?
Whereby folds three months into one digest and still lists nothing specific
Whereby's latest entry covers August through October in a single round-up, again framed around developer experience and SDKs, with no concrete features in the feed text. The last specific capabilities visible are session ratings for Embedded customers in April and the native iOS SDK leaving beta in February.

Synapse 1.164 advertises Matrix v1.16 and v1.17 amid a run of dependency security patches
◆ Current state
Synapse keeps its two-to-three-week cycle of candidates and stables. 1.164.0 went stable on 27 October with support for Matrix v1.16 and v1.17 and a dedicated endpoint for scheduling delayed events (MSC4140). The surrounding releases are security dependency bumps: certifi, a rustls-webpki update that distrusts the compromised eMudhra intermediate CAs, Pillow 13.0.0 for critical image-handling flaws, and msgpack against memory exhaustion on the public room list.
◆ Where it's heading
The homeserver tracks the spec closely, stabilising MSCs as they land in Matrix releases, while backporting each security bump to the previous stable line. Sticky Events and User Status work suggest continued alignment with newer client features.
◆ Prediction
1.165 release candidates should follow within about two weeks, likely with further MSC stabilisations.

Whereby folds three months into one digest and still lists nothing specific
◆ Current state
Whereby's latest entry covers August through October in a single round-up, again framed around developer experience and SDKs, with no concrete features in the feed text. The last specific capabilities visible are session ratings for Embedded customers in April and the native iOS SDK leaving beta in February.
◆ Where it's heading
The cadence is slowing: monthly digests have become a quarterly one, and the framing remains aimed at developers embedding video rather than meeting hosts. Without specifics in the notes, the direction can only be read from the framing, which points at SDK and embedding work.
◆ Prediction
The next entry is most likely another multi-month SDK round-up; the feed gives no signal of a larger launch.
