3.0.0

0f954a7

Release 3.0.0 – AI Functionality

🚀 Highlights

AI-powered Study Plan Generation
The bot uses OpenAI and Groq LLMs to generate detailed, personalized study plans for any topic. If both APIs are unavailable, a local fallback generator is used.
Multilingual Support
All bot messages, study plans, and reminders are automatically translated to the user's selected language (English, Russian, or Spanish) using LLMs (OpenAI or Groq fallback). If translation is not possible, the original English text is sent.
Robust Telegram UX
All messages and buttons always contain non-empty text, eliminating Telegram errors.
Keyboards (format selection, next actions) are always accompanied by a short message to ensure buttons are displayed reliably.
Language Selection Improvements
Language selection buttons are not translated, ensuring the language filter works correctly and the user experience is seamless.
File Export
Study plans can be exported to PDF or TXT files, with proper Unicode and font support.
Reminders
The bot can schedule Telegram reminders for each step of your study plan.
Error Handling & Fallbacks
If OpenAI is unavailable, the bot automatically falls back to Groq for both generation and translation. If both are unavailable, a local generator is used. All errors are logged and handled gracefully.
Full English Documentation & Comments
All code comments, docstrings, and documentation are in English for international collaboration and clarity.
Simplified, Maintainable Codebase
The logic is maximally simplified, with no unnecessary conditions; all stages work reliably and predictably.
TinyDB Storage
All data is stored using TinyDB (no support for other databases).

🆕 How to Use

/start – Greet the bot and select your language.
/plan – Generate a new study plan for any topic.
Choose file format – Save your plan as PDF or TXT.
Set reminders – Schedule Telegram reminders for your study steps.
/myplans – Retrieve your saved study plans.

🛠️ Technical Notes

Python 3.10+ and aiogram 3.x required.
All user-facing text is localized and translated in real time.
All environment variables are loaded from .env.
100% test coverage for all core logic and handlers (pytest).
Project is ready for open source and further extension.
All code and comments must be in English.

📝 Upgrade Notes

No manual migration required.
If you use a previous version, simply update and follow the new English documentation.

v1.2.0

6d617c5

🚀 Release v1.2.0 — Deep Refactor, Better Performance & Stability

✨ Overview

This release introduces a major internal refactoring that significantly improves the bot’s responsiveness, code clarity, and long-term maintainability. Unused features were removed, and core logic was streamlined, resulting in faster performance and higher reliability.

🧠 Highlights

✅ Deep codebase refactor across major handlers and services
⚡ Improved bot performance and responsiveness
🧱 Increased runtime stability and error tolerance
📦 Reduced dependency footprint for faster setup and lower memory usage

🔄 Interaction Improvements

Refactored handlers/planner.py:
- Reorganized user flow — the generated plan is now sent to the user before being saved
- Removed chart visualization as an unnecessary feature
Updated README.md:
- Removed charting feature from functionality list
- Cleaned up tech stack and updated project structure

🗂️ Dependency & File Cleanup

🗑️ Removed services/chart.py (no longer used)
🧹 Removed matplotlib from requirements.txt

🔁 Improved Retry Mechanism

Renamed RETRY_DELAY → BASE_RETRY_DELAY for clarity

Added exponential backoff calculation:

exponential_delay = BASE_RETRY_DELAY * (2 ** attempt)

Enhanced handling of OpenAI API rate limits (HTTP 429)

⚠️ Handling Frequent 429 Errors

If you're experiencing too many 429 Too Many Requests errors, consider the following:

⏱ Increase BASE_RETRY_DELAY
🔁 Increase MAX_RETRIES
🧠 Use a lighter OpenAI model (e.g., gpt-3.5-turbo instead of gpt-4)
💳 Upgrade your OpenAI plan to one with a higher request quota

📌 Migration Notes

✅ Ensure services/chart.py is deleted
🔑 Verify your OPENAI_API_KEY in the .env file
🧪 Adjust retry parameters if needed (see above)

🧪 Compatibility

✅ Tested on Python 3.10 – 3.13
📁 Fully compatible with .env-based local configurations

📍 What’s Next

This stable update lays the groundwork for:

Richer planning interactions
Smarter reminder scheduling
A leaner, more scalable codebase
