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.

What is Fulcrum?

Fulcrum ships MCP server and AI Toolkit to let AI assistants build and query field data forms

Fulcrum is running two parallel tracks: foundational mobile stability (GPS accuracy, offline PDF, Photo FastFill across iOS and Android) and a new AI integration layer via MCP. The mobile side is a steady improvement cadence; the MCP launch is the first genuinely new capability surface the product has added in this window. Photo FastFill (AI-assisted data extraction from photos) continues to mature through early access.

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.

Fulcrum ships MCP server and AI Toolkit to let AI assistants build and query field data forms

◆ Current state

Fulcrum is running two parallel tracks: foundational mobile stability (GPS accuracy, offline PDF, Photo FastFill across iOS and Android) and a new AI integration layer via MCP. The mobile side is a steady improvement cadence; the MCP launch is the first genuinely new capability surface the product has added in this window. Photo FastFill (AI-assisted data extraction from photos) continues to mature through early access.

◆ Where it's heading

The MCP + AI Toolkit launch signals that Fulcrum sees AI-assisted configuration as a primary growth vector — letting field operations teams describe a form in plain language and have an AI build it correctly. Photo FastFill and offline PDF generation via App Extensions are part of the same arc: AI-augmented data capture for field workers who may not be technically proficient. The product is incrementally offloading form-building complexity to AI.

◆ Prediction

Fulcrum will extend the MCP toolset toward reading and writing records directly, not just building forms and schema. Photo FastFill will likely exit early access with more field types supported as the extraction model improves.
