-## [3.9.0] - 2026-01-08
-
-### Added
-
-#### Local Usage Telemetry System
-
-**Privacy-first, local-only tracking to measure your actual cost savings vs baseline.**
-
-- **UsageTracker** ([src/empathy_os/telemetry/usage_tracker.py](src/empathy_os/telemetry/usage_tracker.py))
-  - Thread-safe JSON Lines logging to `~/.empathy/telemetry/usage.jsonl`
-  - SHA256-hashed user IDs for privacy (no PII tracked)
-  - Automatic file rotation after 10 MB
-  - 90-day retention with automatic cleanup
-  - No prompts, responses, file paths, or sensitive data ever tracked
-
-- **CLI Commands** ([src/empathy_os/telemetry/cli.py](src/empathy_os/telemetry/cli.py))
-  - `empathy telemetry show` - View recent LLM calls with beautiful rich tables
-  - `empathy telemetry savings [--days 30]` - Calculate actual savings vs all-PREMIUM baseline
-  - `empathy telemetry compare --period1 7 --period2 30` - Compare time periods
-  - `empathy telemetry reset --confirm` - Clear all telemetry data
-  - `empathy telemetry export --format json|csv --output file` - Export for analysis
-
-- **BaseWorkflow Integration** ([src/empathy_os/workflows/base.py](src/empathy_os/workflows/base.py))
-  - Automatic tracking of every LLM call (tier, model, cost, tokens, duration)
-  - Cache hit/miss tracking
-  - Graceful degradation (workflows continue even if telemetry fails)
-  - Singleton tracker instance shared across all workflows
-
-#### Privacy Guarantees
-
-**What we track:**
-- Workflow name, stage, tier, model, provider
-- Cost, tokens (input/output), timing
-- Cache hit/miss status
-
-**What we NEVER track:**
-- Prompts or responses
-- File paths or code content
-- User email (only SHA256 hash)
-- API keys or credentials
-- Any PII or sensitive data
-
-#### Test Coverage
-
-- **23 unit tests** ([tests/unit/telemetry/test_usage_tracker.py](tests/unit/telemetry/test_usage_tracker.py))
-  - JSON Lines format validation
-  - Thread-safe atomic writes
-  - SHA256 hashing
-  - File rotation and retention
-  - Statistics and savings calculation
-
-- **8 integration tests** ([tests/integration/test_telemetry_integration.py](tests/integration/test_telemetry_integration.py))
-  - End-to-end workflow tracking
-  - Cache hit tracking
-  - Multi-tier tracking
-  - Error handling and graceful degradation
-
-### Changed
-
-- **BaseWorkflow**: Added `_enable_telemetry` flag (default: True)
-- **CLI**: Added telemetry subcommand with 5 commands
+## [3.8.3] - 2026-01-07
