Key Highlights

Messaging

QUIC is enabled by default, falling back to TCP when it stalls (#4337).

Messaging

The REST Messaging API is ready for DST — correct status codes (#4329), a configurable cache that reports overflow (#4330), and endpoint tests and docs (#4331).

Messaging

Rate-limit admission now driven by RLN’s remaining epoch budget (#4309), and the Mix integration gained an end-to-end transport suite (#4324).

Blockchain

Blend connection management per the revised RFC merged (#3510, #3539, #3615), with Node 0.3.0-rc.4/rc.5 and Logos Execution Zone v0.3.0-rc1 published.
