• Activity-based extension: Extends validation when recent API calls succeed
• Graceful degradation: Safe fallback when validation fails
• 20-30% reduction in validation overhead

📊 Real-World Performance Impact

Dashboard Loading

• Before: 4 separate API calls (accounts + categories + merchants + transactions)
• After: 1 preload + 1 combined query = 3-4x faster dashboard

Investment Portfolio

• Before: 1 + N API calls (get accounts, then holdings for each)
• After: 1 batch API call = 5-8x faster for users with multiple investment accounts

Category/Merchant Access

• Before: API call every time
• After: 1-hour cache + preloading = Near-instant response

🔧 New API Methods

# Optimized account queries
accounts_basic = await mm.get_accounts_basic()        # 70% less data
accounts_balance = await mm.get_accounts_balance_only()  # Balance-focused

# Intelligent cache preloading
await mm.preload_cache("dashboard")     # Smart dashboard preload  
await mm.preload_cache("investments")   # Investment data preload
await mm.preload_cache("transactions")  # Transaction-focused preload

# Performance monitoring
stats = mm._graphql_client.get_performance_stats()
print(f"Cache hit rate: {stats['cache']['hit_rate_percent']}%")
print(f"Requests deduplicated: {stats['deduplication']['requests_deduplicated']}")

# Batch operations (eliminates N+1 patterns)
all_holdings = await mm._investment_service.get_all_holdings_batch()
accounts_with_transactions = await mm._account_service.get_accounts_with_recent_transactions()

v0.10.1 - Session Persistence Fix

🐛 Critical Session Persistence Fix

This release resolves the session persistence issues reported in Discussion #34.

Issue Resolved

Problem: Sessions saved with save_session() couldn't be loaded in new processes, failing with:

Session file corrupted (invalid JSON)
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

Root Cause:

1. Default encryption password was generated using hostname/username, which could vary between processes
2. Legacy load_session() method only handled tokens, not CSRF tokens and headers

Solution ✅

1. Stable Encryption Keys

   • Default password now uses home directory instead of hostname/username
   • Ensures consistent encryption/decryption across processes
   • Sessions can now be reliably saved and loaded between different processes

2. Enhanced Session Handling

   • save_session() now saves comprehensive session data (tokens, CSRF, headers)
   • load_session() properly restores all session components
   • Maintains full backward compatibility with existing code

3. Improved Security

   • Sessions continue to use AES-256 encryption
   • Better documentation about secure session storage

Example Usage

# Save session in one process
mm1 = MonarchMoney(session_file="my_session.json", use_encryption=True)
await mm1.login(email, password)
mm1.save_session()  # ✅ Now works reliably

# Load session in different process  
mm2 = MonarchMoney(session_file="my_session.json", use_encryption=True)
mm2.load_session()  # ✅ Now works across processes!
await mm2.get_accounts()  # ✅ Ready to use

👏 Thanks

Special thanks to @matthewdavis for the detailed bug report and investigation in Discussion #34. The root cause analysis was spot-on!

Other Improvements

• Enhanced documentation about session persistence
• Better error handling for edge cases
• Maintained backward compatibility

v0.10.0 - Fix Duplicate get_recent_account_balances Methods

🐛 Bug Fixes

Fixed AccountService.get_recent_account_balances GraphQL Error (#37)

Issue: The AccountService.get_recent_account_balances() method was using a non-existent accountBalanceHistory GraphQL field, causing the error:

{'message': 'Something went wrong while processing: None on request_id: None.', 'locations': [{'line': 2, 'column': 3}]}

Solution:

• Updated to use the correct recentBalances field from the MonarchMoney GraphQL schema
• Added client-side filtering for account_id parameter
• Documented that end_date parameter is not supported by the API

Method Clarification

There are two get_recent_account_balances methods available:

1. MonarchMoney.get_recent_account_balances(start_date)

   • Original method from the base package
   • Gets balance history for all accounts
   • Only supports start_date parameter

2. AccountService.get_recent_account_balances(account_id, start_date, end_date)

   • Enhanced service method (now fixed)
   • Supports filtering by specific account_id
   • end_date parameter ignored with warning (API limitation)
   • Uses same underlying GraphQL query as the original method

🔧 Improvements

• Added daily backwards compatibility checks (previously weekly)
• Fixed compatibility check workflow to match existing test files
• Added manual workflow dispatch trigger for easier testing

👏 Thanks

Special thanks to @bmcdonough for reporting the duplicate methods confusion and GraphQL error in issue #37!

v0.9.5: Fix for update_holding_quantity GraphQL Schema Issues

🐛 Critical Fix: update_holding_quantity GraphQL Schema Issues

Problem Solved

This release fixes the "Something went wrong while processing: None" error in update_holding_quantity that was identified through the new debug logging feature in v0.9.4.

Root Cause

Monarch Money updated their GraphQL API schema, removing several response fields from the updateHolding mutation:

• quantity, costBasisPerShare, currentValue, totalReturn, totalReturnPercent
• Changed errors.messages to PayloadErrorFields format

What's Fixed

• ✅ Updated GraphQL schema to only request fields that still exist
• ✅ Enhanced error handling with new PayloadErrorFields format
• ✅ Simplified response returns {"id": "...", "updated": true} on success
• ✅ Better error messages from improved error parsing

For Issue #27 Users

# Upgrade to get the fix
pip install --upgrade monarchmoney-enhanced

# Should now work!
result = await svc.update_holding_quantity(holding_id, quantity)
print(result)  # {"id": "...", "updated": true}

Debug Logging Success Story

The v0.9.4 debug feature (MonarchMoney(debug=True)) was instrumental in identifying this issue. The detailed GraphQL request/response logs showed exactly which fields were causing the API errors.

Breaking Change Note

The update_holding_quantity response format has changed from detailed holding information to a simple success confirmation, as the detailed fields are no longer available from Monarch Money's API.

Resolves: #27
