Changelog

All notable changes to DevDiff are documented here.

DevDiff uses Semantic Versioning. Every published version is immutable — it works exactly as released, forever. See the Version Policy for details.

[1.0.3] — 2026-06-30 · Hardening Release

Production-grade stability, a fully functional local playground, create-devdiff-app scaffolding, and the immutable versioning contract.

🔐 Immutable Version Guarantee

• VERSION_GUARANTEE constant published in @eldrex/core — the full immutability contract in code.
• checkConfigCompatibility() validates your config against the running CLI version.
• devdiff version --check — checks npm with graceful offline fallback.
• devdiff version --changelog — prints release history in your terminal.

🎮 Local Playground

• devdiff playground — starts an HTTP + WebSocket server on port 3737.
• REST endpoints: /api/workspace, /api/stats, /api/changelog, /api/personas.
• Real-time file-change notifications via WebSocket.
• Dark glassmorphism UI with persona pills, format switcher, and session timer.

🏗️ create-devdiff-app

• npx create-devdiff-app scaffolds a new project with 4 templates: enterprise-dashboard, startup-changelog, ci-integration, minimal.

🌐 Public Demo

• Self-contained playground-demo/index.html — zero server, open in any browser.

🧪 Testing

• 12-phase pre-release verification matrix covering 1000-file stress tests, concurrent dev storms, checkpoint recovery, playground API checks, and security audits.
• 15/15 build tasks, 100 tests passing.

🐛 Bug Fixes

• Fixed ws package bundling issue in @eldrex/cli.
• Exported playground helpers from @eldrex/core index — fixes runtime import error.
• Fixed YAML frontmatter syntax error in docs/index.md.

[1.0.2] — 2026-06-28 · Sentinel Release

Enterprise-grade security hardening, compliance frameworks, multi-agent swarms, and hardware-accelerated local inference.

🔒 Security & Privacy

• Regex-based PrivacyEnforcer — blocks API keys, credentials, and private key structures before any AI provider sees them.
• CVE fixes for webhook path traversal (CVSS 9.1) and prompt injection via commit messages.

🌍 Compliance (10 Frameworks)

• GDPR, CCPA, HIPAA, SOC 2, FedRAMP, ISO 27001, PIPEDA, LGPD, PDPA, Australia Privacy Act.
• devdiff compliance list|apply|status|validate|report

⚡ Local Inference & WebGPU

• WebGPU provider via ONNX Runtime Web.
• Resilient fallback chain: WebGPU → WebAssembly → CPU → Ollama.

🤖 Multi-Agent Swarms

• MultiAgentOrchestrator — 4 agents (Architect, Security, Performance, Docs) collaborate in 4 phases.

🛡️ Vibe-Coder Guardian

• Pre-AI checkpoint snapshots + automatic fallback recovery.
• devdiff recover --checkpoint <id> for manual rollback.

🎭 Personas & VS Code

• 8 built-in personas: Developer, CEO, Educator, PM, Compliance, Journalist, Data Analyst, Robot.
• VS Code extension v1.0.2 with PNG icon support and offline guides.

[1.0.1] — 2026-06-20 · Stability Release

Hardened the core diff engine, fixed post-launch edge cases, and expanded AI provider compatibility.

🐛 Bug Fixes

• Fixed silent failure on repos with no prior commits (empty HEAD).
• Fixed ENOENT crash when .devdiff.config.js is absent — defaults gracefully.
• Fixed incorrect token estimates for Unicode-heavy diffs.
• Fixed devdiff watch not re-attaching after git reset --hard.

⚡ Performance

• AST trimmer improvements — 18% additional token size reduction.
• Batch window tuned from 500ms → 250ms for faster changelog generation.
• Caching now correctly invalidates on config file changes.

🤖 AI Providers

• Ollama health check on startup — clear error if not running.
• Added Anthropic Claude 3.5 Sonnet and Claude 3 Haiku support.
• Improved JSON response parsing — handles trailing commas and extra whitespace.

🎭 New Personas

• robot — machine-readable structured JSON, no prose.
• data-analyst — change metrics, file size deltas, complexity scores.
• journalist — narrative-style changelog for release blog posts.

🔌 Integration Fixes

• GitHub Actions: fixed step ordering for devdiff generate.
• Vite Plugin: HMR overlay now dismisses correctly after generation.
• @eldrex/gateway: fixed Mermaid classDiagram label stripping.
