Planned Next Release:
- v2.1.x (Stable): Dedicated to maximum stability and reliability, this series will remain in maintenance mode with regular releases every two months. The focus is strictly on bug fixes and security updates, with no new major features or breaking changes planned.
- v2.2.0+ (Mainline): Expected in the next 4–6 months, this version introduces an optional rpgp backend for OpenPGPv6 (RFC 9580) support. While this branch may be less stable due to its experimental nature, GnuPG remains our primary, long-term strategic backend and will continue as the default, fully-supported choice across all versions.

Although the GpgFrontend's UI looks simple, architecture and design behind it are actually not easy for beginners, especially for developers who are not familiar with C++, Qt, and multithreading. I was struggling hard in these areas since the beginning of the project as well. An AI-assisted Wiki has been created through analysis of the GpgFrontend source code. I've glanced through it and I would say that it can be of great help, but for some details, it's not entirely accurate. Therefore, I would recommend developers to read the source code with the help of the wiki, but not to rely on it completely. If you have any questions about the code, feel free to ask me directly or open an issue on GitHub.
For setting up the development environment, please refer to the Development Environment Setup Guide.
GpgFrontend inherits the codebase from the discontinued but easy-to-use gpg4usb. As described in my blog post "The Past and Present of GpgFrontend: My Journey with an Open-Source Encryption Tool", the project began with a simple question:
"What if everyone could have a small, reliable, and secure 'crypto machine'. A tool that makes encryption as tangible and trustworthy as turning a key in a lock?"
