Version 4.0.1 Release Notes

New Features:

• Increased the KDF iteration count to 650000, to maintain a high level of security as hardware capabilities evolve.
• Implemented a centralized error handler to manage exceptions in a consistent manner.
• Integrated logging to keep a record of unexpected events or errors for debugging purposes.
• Introduced user-friendly error messages via popups to inform users of issues during operation, such as incorrect password entry or file not found errors.

Improvements:

• Improved error handling by specifying individual except blocks for different exception types, providing more accurate diagnostics and user feedback.
• Enhanced the decrypt_note_with_key_file function for external script-based decryption of notes using a known password and the key.enc file.
• Refined the software disclaimer for clarity and conciseness.
• Updated the load_notes method to handle InvalidTag exceptions gracefully, preventing crashes and providing better user feedback.

Fixes:

• Fixed potential unhandled exception issue by catching and logging InvalidTag exceptions, which could occur when entering a wrong password.
• Addressed potential code duplication concerning encryption/decryption operations.

Security:

• Reviewed and provided recommendations for enhancing the security of the key derivation process and file handling to better protect against brute force and other types of attacks.
