Release History of Ruflo: From v1.0.1 to v3.5.0
Ruflo evolved from an initial AI-agent orchestration tool in January 2025 through three major architectural iterations to a stable, production-ready platform released as v3.5.0 in February 2026.
The release history of Ruflo (formerly developed under the claude-flow namespace) is documented across multiple changelog files in the ruvnet/ruflo repository. This timeline tracks the project's rapid evolution from a monolithic CLI tool to a modular, MCP-first agentic orchestration system.

V3 Alpha Series: Architecture Overhaul (October 2025–January 2026)
The V3 series represented a complete architectural rewrite, introducing a modular monorepo structure, MCP-first APIs, and the @claude-flow/* package ecosystem. Development occurred in the v3/ directory with its own v3/CHANGELOG.md.
v3.0.0-alpha.1 (October 1, 2025)
Split the monorepo into 10 independent @claude-flow/* packages, introduced 215 MCP tools, and implemented a 15-agent hierarchical mesh. Added Flash-Attention and SONA integration for hardware-accelerated inference.

Introduced the @claude-flow/guidance control plane, a Rust-WASM policy kernel, the ContinueGate safety gate, and a 22-benchmark performance suite.
v3.0.0-alpha.150 (November 30, 2025)
Added SONA & SemanticRouter integration, memory-namespace support, and MCP-tool naming fixes for Claude Desktop compatibility.
v3.0.0-alpha.170 (December 10, 2025)
Launched the Plugin Marketplace with 8 official plugins and IPFS registry support, the Gas Town bridge, and 10 RuVector WASM plugins.
v3.0.0-alpha.184 (December 25, 2025)
Overhauled CLI help categorization, introduced a curl-style installer script, and optimized packages for SEO.
v3.0.0-alpha.1 (January 4, 2026)
A major architecture overhaul with 10 ADRs (Architecture Decision Records), Flash-Attention speed-ups (2.49–7.47×), HNSW search improvements (150–12,500×), and 83% memory reduction. Included major security hardening.
Rebranding to Ruflo: Stable Release (February 2026)
The project officially rebranded from claude-flow to Ruflo, consolidating the V3 architecture into a stable, production-ready release.
v3.5.0 (February 27, 2026)
The first stable Ruflo release marked the completion of the rebrand, integrating agentic-flow v3, 215 MCP tools, and comprehensive security hardening (CVE-1/2/3 patches). This version introduced the health-check doctor and reported zero known vulnerabilities.
v3.1.0-alpha.55 (February 27, 2026)
Integrated AgentDB v3.0.0-alpha.9 with 8 controllers and a mutation-guard proof engine, added new MCP tools, and fixed a GNN crash.
v3.1.0-alpha.43 (February 15, 2026)
Fixed CLI branding to use ruflo instead of claude-flow and resolved a Windows ESM import crash.
v3.1.0-alpha.36 (February 10, 2026)
Ensured hook backward-compatibility, fixed Windows npm install crashes, and bumped agentdb.
v3.1.0-alpha.29 (February 1, 2026)
Applied security fixes, introduced Agent Teams hooks, and added a settings flag for the upgrade command.
