- Improved error handling for version checks and command execution, enhancing usability and flexibility in Docker environments.
- Default Python version is set to 3.12, with the option to specify a different version during installation.
- Changed the installation script for pyenv to create a user-specific environment file at $HOME/.pyenv-env.sh instead of a system-wide file in /etc/profile.d/.
