## [0.9.9] - 2025-12-22

### 🔧 Improvements

#### Changed

- **Rate Limiting: API Key-Based** - Rate limiting now uses API key instead of IP address
  - Fairer distribution for robots behind NAT/proxy (multiple robots sharing same IP)
  - Each API key gets its own rate limit bucket per endpoint

  - No more hardcoded token addresses in JavaScript
  - Change token via single environment variable: `ACTO_TOKEN_GATING_MINT`

- **CLI Access Check** - Now uses configured defaults
  - `--mint`, `--minimum`, and `--rpc` are now optional
  - Falls back to configured ACTO token if not specified
  - Simpler usage: `acto access check --owner WALLET_ADDRESS`

---

## [0.9.8] - 2025-12-22

### 🚀 Performance Optimization

This release includes major SQL performance improvements that eliminate memory-intensive data loading patterns.

#### Added

- **Optimized SQL Aggregation Methods** for `ProofRegistry`:
  - `count()` - Count proofs using SQL COUNT instead of len(list())
  - `count_by_robot()` - Group counts by robot_id using SQL GROUP BY
  - `count_by_task()` - Group counts by task_id using SQL GROUP BY
  - `count_by_date()` - Timeline aggregation for the last N days
  - `get_activity_range()` - First/last activity using SQL MIN/MAX
  - `exists_by_robot()` - Efficient existence check
  - `get_unique_robot_ids()` - Distinct robot IDs via SQL
  - `get_unique_task_ids()` - Distinct task IDs via SQL
  - `get_device_stats()` - Aggregated device statistics in one query

- **Optimized Fleet Store Method**:
  - `get_fleet_data_optimized()` - Uses SQL aggregations instead of loading all proofs

#### Changed

- **Wallet Stats Endpoint** (`/v1/stats/wallet/{address}`): Now uses SQL aggregations instead of loading up to 10,000 proof records into memory
- **Fleet Endpoints** (`/v1/fleet`, `/v1/fleet/devices/{id}`, `/v1/fleet/devices/{id}/name`): Now use optimized SQL queries
- **Stats Router**: Updated to use new aggregation methods

#### Performance Impact

| Metric | Before | After | Improvement |
|--------|--------|-------|-------------|
| Memory per request | ~10MB+ (10K records) | ~1KB (aggregates only) | **99.99%** reduction |
| Network I/O | All record data | Counts/aggregates only | **~99%** reduction |
| Query time (10K proofs) | O(n) Python iteration | O(1) SQL aggregation | **~100x** faster |

---

## [0.9.7] - 2025-12-22

### 🔧 Improvements & Bug Fixes

This release includes several stability improvements and bug fixes.

#### Fixed

- **Tests**: Updated test suite to use internal verification function (`_verify_proof_internal`) instead of deprecated `verify_proof()`
- **User-Agent Version**: SDK clients now use dynamic version from `__version__` instead of hardcoded value

#### Changed

- **Rate Limiter Memory Leak Fix**: The rate limiter now automatically cleans up stale bucket entries to prevent unbounded memory growth
  - New `bucket_ttl` setting: Bucket expiry time (default: 1 hour)
  - New `cleanup_interval` setting: Cleanup frequency (default: every 1000 requests)
  - Buckets that haven't been accessed within TTL are automatically removed

#### New Configuration Options

| Environment Variable | Default | Description |
|---------------------|---------|-------------|
| `ACTO_RATE_LIMIT_BUCKET_TTL` | `3600.0` | Time in seconds before inactive buckets expire |
| `ACTO_RATE_LIMIT_CLEANUP_INTERVAL` | `1000` | Run cleanup every N requests |

## [0.9.6] - 2025-12-22

### 🔒 Security Cleanup

This release removes unused legacy authentication endpoints that were never integrated into the production authentication flow.

#### Removed

- **`POST /v1/auth/token`** - Unused username/password endpoint (security risk)
- **`POST /v1/auth/refresh`** - Unused refresh token endpoint

These endpoints were placeholder code from early development and were never used by the SDK, CLI, dashboard, or any client. The actual authentication uses Solana wallet-based authentication via `/v1/auth/wallet/connect` and `/v1/auth/wallet/verify`.

#### Changed

- Updated `docs/SECURITY.md` to document the actual wallet-based authentication flow
- Added Token Gating documentation
- Cleaned up unused imports (`OAuth2TokenResponse`, `create_jwt_dependency_optional`, `require_api_key`)

#### Security

- Removed potential security vulnerability from unverified token creation endpoint
- All authentication now properly uses wallet signature verification + token gating

---

## [0.9.5] - 2025-12-21

### 🐛 SDK Client Fix

#### Fixed

- `client.get_proof()` now correctly parses API response format
- API returns `{"proof_id": ..., "envelope": ...}` - client now extracts envelope

---

## [0.9.4] - 2025-12-21

### 🐛 CI/CD Fix

#### Fixed

- Updated GitHub Actions test to not import removed `verify_proof`
- Test now validates `ACTOClient` import instead

---

## [0.9.3] - 2025-12-21

### 🐛 Server Hotfix

#### Fixed

- Server now uses internal verification function (`_verify_proof_internal`)
- SDK continues to block local verification (requires API)
- Fixed Vercel deployment crash due to missing import

---

## [0.9.2] - 2025-12-21

### 🔧 Helius RPC Integration

This release ensures all token balance checks use the backend's configured RPC (Helius) instead of public endpoints.

#### Changed

- Backend uses Helius RPC for all token balance checks when configured
- `rpc_url` is now optional in `/v1/access/check` - defaults to backend config
- SDK clients default to empty `rpc_url` (backend uses Helius)
- Removed hardcoded public RPC from dashboard and playground
- Updated all documentation to reflect Helius integration

#### Fixed

- Dashboard and playground no longer send public RPC URL
- Consistent RPC usage across all token gating checks

---

## [0.9.1] - 2025-12-21

### 🔒 API-Only Verification

This release removes local proof verification. All proofs must now be verified through the ACTO API to ensure integrity, compliance, and fleet tracking.

#### Breaking Changes

- **`verify_proof()` removed** - Local verification is no longer available
- **`verify_proof_async()` removed** - Use `AsyncACTOClient.verify()` instead
- **`ProofChain.verify_chain()`** - Now requires an `ACTOClient` parameter

#### Migration Guide

**Before (0.9.0):**
```python
from acto.proof import verify_proof
is_valid = verify_proof(envelope)  # ❌ No longer works
```

**After (0.9.1):**
```python
from acto.client import ACTOClient
client = ACTOClient(api_key="...", wallet_address="...")
result = client.verify(envelope)  # ✅ Use API verification
print(result.valid)
```

#### Changed

- `verify_proof()` now raises `ProofError` with migration instructions
- `verify_proof_async()` now raises `ProofError` with migration instructions
- `ProofChain.verify_chain(client)` now requires ACTOClient parameter
- Updated all documentation to reflect API-only verification
- Updated README.md, docs/API.md, examples/, and Jupyter notebooks
- Updated dashboard documentation

#### Why This Change?

- **Integrity**: Centralized verification ensures all proofs go through the official API
- **Compliance**: Enables audit trails and compliance reporting
- **Fleet Tracking**: Enables automatic device discovery and fleet management
- **Token Gating**: Ensures only authorized users can verify proofs

## [0.7.3] - 2025-12-21

### 🔧 Dashboard Key Management Fixes

This release fixes critical issues with API key management in the dashboard.

#### Fixed

- **Key Actions via Event Delegation** - Rename, toggle, and delete buttons now work reliably using event delegation instead of inline onclick handlers with JSON.stringify (prevents HTML attribute parsing issues)
- **Delete Keys Permanently** - Delete button now permanently removes keys from the database instead of just deactivating them
- **Toggle vs Delete Distinction** - Toggle (on/off switch) deactivates keys but keeps them visible; Delete removes them completely
- **Key Statistics Loading** - Fixed 401 errors when viewing key statistics (requires `ACTO_JWT_SECRET_KEY` environment variable on Vercel)

#### Changed

- Improved success checking for delete operations
- Keys list now loads with `include_inactive=true` to show toggled-off keys

#### Important

- **Vercel Users**: Set `ACTO_JWT_SECRET_KEY` environment variable with a fixed secret to prevent JWT validation issues across serverless instances
