OpenTextShield v2.7 Release Notes

Release Date: October 23, 2025 Version: 2.7.0 Status: ✅ Production Ready

Executive Summary

OpenTextShield v2.7 represents a major security and platform enhancement release. This version introduces non-root execution, multi-stage Docker optimizations, and cross-platform support (ARM64 + AMD64), reducing the security vulnerability surface by 60-80% while maintaining 100% API compatibility.

Key Metrics

  • Image Sizes: 1.9GB (ARM64) | 3.81GB (AMD64)
  • Security: 60-80% fewer vulnerabilities
  • Compatibility: 100% backward compatible with v2.6
  • Tested Platforms: Apple Silicon (M1/M2/M3/M4), Ubuntu 24.04, AWS EC2, Kubernetes
  • Performance: 172 req/s throughput (10-server deployment)

What's New

🔒 Security Enhancements

Non-Root User Execution

  • Change: Container now runs as unprivileged user (UID 1000)
  • Benefit: Prevents container escape attacks, reduces blast radius
  • Impact: Zero - fully transparent to users
  • Status: ✅ Production ready

Multi-Stage Docker Builds

  • Change: Separate build and runtime stages in Dockerfile
  • Benefit: Eliminates build tools from final image
  • Impact: Smaller image size, fewer vulnerabilities
  • Before: All build dependencies included
  • After: Only runtime dependencies (60-80% fewer CVEs)

Enhanced Security Middleware

  • IP Verification: Optional IP whitelist support
  • CORS Hardening: More restrictive default CORS settings
  • Request Validation: Stricter input validation on all endpoints
  • Status: ✅ Enabled by default, configurable

Vulnerability Reduction

  • Upgraded base image from Ubuntu 22.04 to 24.04
  • Removed unnecessary system packages
  • Updated all Python dependencies to latest secure versions
  • Security scanning: 0 critical, 0 high severity issues

📦 Image Improvements

Smaller, Optimized Images

v2.6 vs v2.7 Size Comparison:
- Default build: ~2.2GB → 1.9GB (13% reduction)
- AMD64 build: ~4.1GB → 3.81GB (7% reduction)
- Distroless: NEW → 1.4GB (35% smaller than default)

Faster Startup

  • Optimized dependency resolution
  • Pre-built wheel packages
  • Parallel installation where possible
  • Result: Startup time unchanged (~2-3 min), more reliable

Better Layer Caching

  • Build layers reorganized for better Docker caching
  • Dependency layer separated from code layer
  • Result: Faster rebuilds during development

  • Running long-lived containers (memory fixes)

Safe to Skip If

  • Running in completely isolated environment
  • Security not a concern for your use case
  • Performance is critical and stable (same latency)
