v2.3.2

2026-03-18

🆕 New — OCR & Document Extraction

FAC now supports extracting text from images and scanned PDFs directly through your AI assistant. Two backends are available out of the box:

PaddleOCR integration — high-accuracy text extraction using PaddleOCR with support for multiple languages. Runs in a subprocess with configurable memory limits and timeouts to keep your server stable.
Vision model support — use Ollama-based vision models (e.g., deepseek-ocr:latest) as an alternative OCR backend for more complex document understanding.
Configurable OCR settings — choose your preferred backend, language, timeout, and memory limits directly from Assistant Core Settings. No config files to edit.
Model warmup — optional background warmup for PaddleOCR models so the first extraction request is fast.

🚀 Improvements

Audit log cleanup — automatic retention policy (default 180 days) keeps your audit logs manageable without manual intervention. Configure the retention period in Assistant Core Settings to match your compliance requirements. Cleanup runs daily via a scheduled job.
Better report feedback — report tools now provide clear guidance when used incorrectly, instead of failing silently. Default filters are also included in generate_report responses so the AI knows what parameters were applied.
OAuth localhost support — native apps like OpenCode and MCP Inspector can now register with HTTP localhost redirect URIs without errors. This follows RFC 8252 which explicitly allows HTTP for loopback connections since the traffic never leaves your machine.
MCP 2025-06-18 spec — updated to the latest MCP authentication specification for better compatibility with newer MCP clients.
Code execution limits — the run_python_code sandbox now enforces configurable timeout, memory, CPU, and recursion limits to prevent runaway scripts. All limits are configurable from Assistant Core Settings.
Settings defaults — all settings now correctly apply their default values on fresh installs and upgrades. No more missing defaults after bench migrate.

🔒 Security Fixes

Fixed unauthorized access to protected API endpoints — non-authenticated users were able to reach endpoints that should have required authentication (#108)
Fixed sensitive credential values appearing in server logs — replaced with non-sensitive status messages so your logs are safe to share during debugging (#114)
Removed unused API endpoints (handle_assistant_request, force_test_logging, log_assistant_connection, log_assistant_audit) that were unnecessarily exposed and could be called by any authenticated user (#111, #105)
Added regression tests for admin API permissions to catch authorization issues early in CI

🐛 Bug Fixes

Fixed duplicate "Security" tabs appearing in Assistant Core Settings
Fixed PaddleOCR 3.x API incompatibility — updated constructor and call patterns to work with the latest PaddleOCR release (#107)
Fixed overly aggressive import restrictions in the Python sandbox that broke numpy/pandas internal lazy imports

🧹 Housekeeping

Removed ~1,150 lines of dead code — unused streaming manager, response builder, cache utilities, dashboard helpers, and stale constant definitions
Added code execution security documentation

🔄 Migration

After upgrading to v2.3.2, run:

bash

bench --site your-site migrate

This will:

Apply default values for all settings fields
Update MCP protocol version to 2025-06-18 spec
Set up audit log retention (180 days default)

2026-02-06

Database-backed plugin & tool management with Frappe V16 support

What's New

This release introduces a robust, database-backed system for managing plugin and tool enable/disable states and access control. It replaces the previous JSON-based approach with new DocTypes for granular, atomic, and multi-worker-safe configuration. Frappe V16 is now officially supported.

Plugin & Tool Management Architecture

FAC Plugin Configuration DocType

A new DocType for atomic, database-backed plugin enable/disable control with:

Audit trail for every state change
Automatic cache invalidation for multi-worker consistency
API functions for toggling and querying plugin states programmatically

FAC Tool Configuration DocType

A new DocType for per-tool configuration and access control with:

Enable/disable toggle for individual tools
Category assignment (read_only, write, read_write, privileged)
Role-based access control via FAC Tool Role Access child table
Automatic tool category detection via AST parsing of tool source code

Why This Matters

Before (JSON)	After (DocType)
File-based state, prone to corruption	Atomic database writes
No change history	Full audit trail with timestamps and users
Stale reads across workers	Cache invalidation ensures consistency
Race conditions under load	Database locks prevent conflicts
File I/O bottleneck	Scales with your database

Frappe V16 Support

Official support for Frappe V16 alongside V15
Conditional OAuth settings UI based on Frappe version
Full backward compatibility with V15 installations

Documentation Updates

Updated architecture docs describing the new DocType-based configuration system
Administrator guide for tool and plugin management
Developer documentation for automatic tool category detection with examples and best practices
Updated main documentation index for easier navigation

Other Improvements

Copyright and license headers added to new and updated modules
Improved state persistence flow: UI → API → DocType → Cache Invalidation → Consistent reads

Upgrade Guide

bash

cd apps/frappe_assistant_core
git pull
bench --site your-site migrate

Migration will automatically:

Create FAC Plugin Configuration records for existing plugins
Create FAC Tool Configuration records for registered tools
Auto-detect tool categories via AST parsing

v2.0.1

2025-07-26

Release Date: July 26, 2025
Version: 2.0.1
Type: Major Bug Fixes & Tool Improvements

🎯 Overview

Version 2.0.1 is a significant maintenance release that addresses critical issues in document creation, dashboard chart functionality, and custom tool discovery. This release dramatically improves the reliability and usability of AI assistant tools for Frappe Framework.

🚀 Major Improvements

📋 Document Creation Tool Overhaul

Problem Solved: The create_document tool frequently failed when creating documents with child tables (Purchase Orders, Sales Invoices, BOMs), causing LLMs to fall back to less reliable methods.

Key Fixes:

✅ Fixed Child Table Handling: Proper doc.append() usage instead of naive setattr()
✅ Automatic Field Validation: Pre-validates required fields before creation attempts
✅ Enhanced Error Messages: Specific guidance for different error types with actionable suggestions
✅ Validate-Only Mode: Test document structure before actual creation
✅ Comprehensive Examples: Updated tool descriptions with proper child table formatting

Impact: Document creation success rate increased from ~60% to ~95% for complex DocTypes.

📊 Dashboard Chart System Rebuild

Problem Solved: Dashboard charts were created but failed at runtime with empty "Time Series Based On" and "Value Based On" fields, causing blank charts in dashboard view.

Root Cause: Incorrect field mapping between tool parameters and Frappe's Dashboard Chart DocType structure.

Complete Fix:

✅ Correct Field Mapping:
- based_on = Time Series Based On (date field)
- timeseries = Time Series flag (boolean)
- group_by_based_on = Group By Based On (grouping field)
- value_based_on = Value Based On (aggregation field)
✅ Filter Format Conversion: Proper conversion from dict to Frappe's list format
✅ Smart Field Detection: Auto-detects appropriate date and grouping fields per DocType
✅ Comprehensive Validation: Pre-validates chart configuration before creation
✅ Runtime Testing: Charts are tested for functionality before being saved

Impact: Charts now work immediately in dashboard view with proper data visualization.

🔧 Custom Tool Discovery Enhancement

Problem Solved: Custom tools from external Frappe apps were not being properly discovered through the hooks system.

Fix: Enhanced tool registry to properly scan and load tools from assistant_tools hook in external apps.

Impact: Enables seamless integration of custom business-specific tools from any Frappe app.

🐛 Critical Bug Fixes

Document Creation Issues

Fixed: 'dict' object has no attribute 'is_new' error in child table creation
Fixed: Missing required field validation causing creation failures
Fixed: Poor error messages that didn't guide users to solutions

Dashboard Chart Issues

Fixed: TypeError: 'NoneType' object is not callable in chart data retrieval
Fixed: Unknown column 'tabItem.posting_date' in 'WHERE' SQL errors
Fixed: Empty time series and value fields in created charts
Fixed: Charts displaying no data despite successful creation

Tool Discovery Issues

Fixed: External app tools not being loaded through hooks system
Fixed: Inconsistent tool availability across different Frappe installations

🛠️ Technical Improvements

Enhanced Validation Framework

Smart Field Detection: Context-aware field auto-detection based on DocType metadata

🚀 Features

Automatic Artifact Streaming System

Implement comprehensive artifact streaming for all tools

We've introduced an intelligent artifact streaming system that significantly improves handling of large tool results and enhances user experience:

Key Improvements:

Smart Detection: Automatically detects large results (>5 lines or >1000 characters) and streams them appropriately
Tool Categorization: Intelligent categorization system for different tool types with specific handling logic
Flexible Display Modes:
- Preview mode for results under 10k characters
- Truncated mode for results over 10k characters
Enhanced Workflow: Mandatory streaming instructions prevent conversation length limits
Professional Deliverables: Tool-specific artifact type suggestions and section templates

Technical Enhancements:

Resolved timestamp serialization errors in analyze_frappe_data tool
Added automatic import statement removal in execute_python_code tool
Fixed NoneType startswith errors in report execution
Comprehensive streaming guidance and formatting improvements

🐛 Bug Fixes

Admin Panel API and Statistics Resolution

Resolve critical admin panel functionality and usage statistics display

Fixed multiple API-related issues that were preventing proper admin panel operation and statistics display:

API Endpoints:

Added missing API endpoints: get_usage_statistics, ping, force_test_logging
Fixed server control methods by adding required @frappe.whitelist decorators
Ensured proper response format matching frontend expectations (success/error structure)

Database and Query Fixes:

Corrected database column references (date → creation) in statistics queries
Removed unsupported ignore_permissions parameter from db.count() calls
Resolved table existence check issues in tool registry queries
Enhanced error handling with graceful fallbacks for missing data

Impact:

Admin panel now fully functional with all control methods working
Usage statistics display correctly with proper data formatting
Improved system reliability with better error handling

📋 Summary

This release focuses on improving system reliability and user experience through enhanced artifact streaming capabilities and critical admin panel fixes. The automatic streaming system ensures better handling of large datasets while the API fixes restore full admin functionality.
