Changelog

Every release, every feature, every fix. Aura ships fast and breaks nothing.

v0.8.1

Latest
March 16, 2026 | Sentinel Auto-Reply & Cloud Production

Highlights

  • Agents auto-reply to unread messages when their session ends
  • Snapshot guard — warns when files are modified without a snapshot
  • Unread messages shown inline at session start (BLOCKING)
  • AI-powered memory compaction (open-source)
  • Cloud: trial periods, usage metering, Stripe idempotency

Feature Sentinel auto-reply: agents send "[AUTO]" status when session ends with unread messages
Feature Snapshot guard: 🛡️ SNAPSHOT MISSING warning injected when files modified without snapshot
Feature Session-start message surfacing: aura_status shows full message previews with BLOCKING instruction
Feature aura_memory_compact MCP tool ported to open-source (AI-powered entry compression)
Feature Cloud: 14-day trial period on org creation with effective_plan logic
Feature Cloud: usage metering with plan limits (free=100/mo, team=10K, enterprise=unlimited)
Feature Cloud: Stripe webhook idempotency via processed_webhooks table
Feature Cloud: presence stale cleanup (5min TTL, 30min hard delete)
Fix Cloud: CORS restricted to auravcs.com + localhost dev origins only
Fix Cloud: JWT secret panics if unset in production (no more hardcoded fallback)

v0.5.0

March 7, 2026 | Duo Mode & Symphony

Highlights

  • Multi-agent orchestration — run Claude Code and Gemini CLI in parallel
  • Linear-driven AI development workflows
  • TOON encoder for 30-60% token savings on MCP responses
  • Durable file snapshots — your work is never lost

Feature Duo Mode: parallel multi-agent relay engine with dependency-aware scheduling
Feature Smart assignment: complex refactors to Claude, everything else to Gemini (free tier)
Feature Inter-agent relay messages — agents see what the other did between rounds
Feature Claude session resumption across waves (saves 50% context tokens)
Feature 3-strike failure handling with automatic agent swapping
Feature Symphony: connect Linear issues directly to AI agent execution
Feature WORKFLOW.md config for Symphony pipelines
Feature TOON (Token-Oriented Object Notation) encoder for MCP tool responses
Feature Durable file snapshots in .aura/snapshots/ — survives without git commits
Feature aura_snapshot MCP tool — AI agents call before editing files
Feature aura_snapshot_list MCP tool — list all recoverable snapshots
Feature Watcher daemon auto-snapshots on every file change
Feature Dev metrics dashboard (React + Vite) — visualize orchestration, checkpoints, reviews
Fix Rewind now searches durable snapshots first, then walks 50 commits of git history
Fix Auto-snapshot before rewind for safety net recovery
Performance Snapshot auto-prune: 50 per file, 500 total max (2.5MB ceiling)
Performance TOON reduces token count by 30-60% for structured MCP responses

v0.4.0

  • Rename-proof logical node identity and diffing
  • 148 features across CLI, MCP, API, and Dashboard

Feature Semantic PR review: detects logical renames, layer violations, cross-branch conflicts
Feature Rename-proof Structural Skeleton Hashing — identity persists regardless of name
Feature Dev Metrics dashboard with checkpoint timeline and logic graph
Feature Policy packs: security, payments, web-app architectural invariant templates
Feature aura prove — mathematically verify behavioral goals via AST path tracing
Feature aura fix — autonomous shadow-branch violation resolution
Feature TypeScript and JavaScript tree-sitter parser support
Feature REST API with 42 endpoints for IDE and CI/CD integration
Fix Non-destructive hook installation — preserves existing git hooks
Performance Handover context compression: 90%+ token reduction for agent relay

v0.3.0

January 18, 2026 | The Intelligence Update

Highlights

  • MCP Server with 16 tools for AI agent integration
  • GSD Orchestrator for wave-based execution
  • Continuous semantic tracker daemon

Feature MCP Server (JSON-RPC 2.0 over stdio) with 16 semantic tools
