SochDB v0.3.3 Release Notes

Release Date: January 5, 2026

🎉 New Features​

🕸️ Graph Overlay System​

A lightweight graph layer built on top of SochDB's KV storage for agent memory management:

Features:

  • Node operations: Add, Get, Update, Delete with typed nodes
  • Edge operations: Add, Get, Delete with relationship tracking
  • Graph traversal: BFS, DFS, Shortest Path algorithms
  • Neighbor queries: Get incoming/outgoing neighbors with filters
  • Subgraph extraction: Extract connected components
  • Namespace isolation: Multi-tenant graph support

Use Cases:

  • Agent conversation history with causal chains
  • Entity relationship tracking across sessions
  • Action dependency graphs for planning
  • Knowledge graph construction

SDKs: Python, Go, Node.js/TypeScript

📊 Context Query Enhancements​

Improved token-aware context retrieval:

  • Better token estimation for GPT-4, Claude models
  • Enhanced deduplication strategies
  • Multi-format support (text, JSON, markdown)
  • Relevance scoring improvements

🛡️ Policy & Safety Improvements​

Enhanced agent safety controls:

  • Additional pre-built policy templates
  • Better audit trail generation
  • Performance optimizations for high-throughput scenarios

🔀 Tool Routing Enhancements​

Multi-agent coordination improvements:

  • Dynamic agent discovery
  • Better load balancing strategies
  • Failover improvements
  • Agent health monitoring

🐛 Bug Fixes​

  • Fixed edge case in BFS traversal with cyclic graphs
  • Resolved context query token counting for very long documents
  • Fixed policy hook execution order in nested transactions
  • Corrected tool routing priority when multiple agents match

🚀 Performance Improvements​

  • 15% faster graph traversal algorithms
  • Reduced memory usage for large graph structures
  • Optimized prefix scanning for graph edges
  • Improved context query compilation time

  • Architecture docs updated with graph storage model
  • Examples added for all new features

🔄 Breaking Changes​

None. This is a fully backward-compatible release.

📝 Migration Guide​

No migration needed. All existing code continues to work.

To use new features:

Python:

from sochdb import Database, GraphOverlay
db = Database.open("./db")
graph = GraphOverlay(db, namespace="demo")

Go:

import sochdb "github.com/sochdb/sochdb-go"
db, _ := sochdb.Open("./db")
graph := sochdb.NewGraphOverlay(db, "demo")

Node.js:

import { Database, GraphOverlay } from '@sochdb/sochdb';
const db = await Database.open('./db');
const graph = new GraphOverlay(db, 'demo');

🙏 Acknowledgments​

Special thanks to all contributors who helped make this release possible!
