What is Feedly?
Feedly's reader roots recede as threat-intel agents take over the changelog
Feedly's changelog is now almost entirely a cyber threat intelligence product log. The last three months added models tuned for insider threats and threat actor campaigns, Suricata rule extraction, SPL queries alongside KQL, GreyNoise and VirusTotal enrichment, and a Vulnerability Agent. The August release extends Custom Intel Agents with Analyze and Research actions and adds a Censys lookup to IP cards.
What is Zipkin?
Zipkin's last release was January 2025 — a dependency bump, and then nothing.
The recent history is three consecutive maintenance releases whose entire content is dependency and base-image updates: 3.4.3 aligned Maven versions with the Docker images, 3.4.2 and 3.4.1 moved Spring Boot, Netty, Micrometer, Armeria, Alpine and the JRE forward to clear CVEs. The last release carrying a feature was 3.4 in May 2024, which added OpenSearch v2 as a storage backend using the existing ES_-prefixed environment variables.

Feedly's reader roots recede as threat-intel agents take over the changelog
◆ Current state
Feedly's changelog is now almost entirely a cyber threat intelligence product log. The last three months added models tuned for insider threats and threat actor campaigns, Suricata rule extraction, SPL queries alongside KQL, GreyNoise and VirusTotal enrichment, and a Vulnerability Agent. The August release extends Custom Intel Agents with Analyze and Research actions and adds a Censys lookup to IP cards.
◆ Where it's heading
The arc runs from retrieval toward analysis: earlier releases broadened what Feedly could collect, recent ones give analysts agents that reason over it and emit artifacts their existing tools accept. Report Builder citations that trace a claim to its source passage target the trust problem gating generated intelligence in a SOC. Coverage has become table stakes; the contest is over whether analysts accept the machine's conclusions.
◆ Prediction
Expect the agent surface to keep gaining verbs rather than new data sources, with more export formats aimed at the SIEM and detection tooling analysts already run.
Zipkin
0.0ANALYTICS
Zipkin's last release was January 2025 — a dependency bump, and then nothing.
◆ Current state
The recent history is three consecutive maintenance releases whose entire content is dependency and base-image updates: 3.4.3 aligned Maven versions with the Docker images, 3.4.2 and 3.4.1 moved Spring Boot, Netty, Micrometer, Armeria, Alpine and the JRE forward to clear CVEs. The last release carrying a feature was 3.4 in May 2024, which added OpenSearch v2 as a storage backend using the existing ES_-prefixed environment variables.
◆ Where it's heading
This is a project in preservation rather than development. The pattern across the window — feature in May 2024, then three releases of purely defensive dependency work, then silence since January 2025 — describes a mature tracing server being kept safe to run rather than extended. The distributed-tracing work that would once have landed here now largely happens in OpenTelemetry, which Zipkin interoperates with rather than competes against.
◆ Prediction
The feed has produced nothing for nineteen months, so the honest read is that no next release is scheduled. If one comes, the shape of the last three says it will be another dependency and base-image refresh rather than new capability.
