- Introduce advanced mode for x86/x64 arch, it has some limitations in trial version
- Add option –advanced for command obfuscate
- Add new property advanced_mode for project
A new feature Advanced Mode is introduced in this version. In this mode the structure of PyCode_Type is changed a little to improve the security. And a hook also is injected into Python interpreter so that the modified code objects could run normally. Besides if some core Python C APIs are changed unexpectedly, the obfuscated scripts in advanced mode won’t work. Because this feature is highly depended on the machine instruction set, it’s only available for x86/x64 arch now. And pyarmor maybe makes mistake if Python interpreter is compiled by old gcc or some other C compiles. It’s welcome to report the issue if Python interpreter doesn’t work in advanced mode.
Take this into account, the advanced mode is disabled by default. In order to enable it, pass option –advanced to command obfuscate. But in next minor version, this mode may be enable by default.
Before upgrading, please estimate Python interpreter in product environments to be sure it works in advanced mode. Here is the guide
It is recommended to upgrade in the next minor version.

Pyarmor v3.4 introduces a group new commands. For a simple package, use command obfuscate to obfuscate scripts directly. For complicated package, use Project to manage obfuscated scripts.
Project includes 2 files, one configure file and one project capsule. Use manifest template string, same as MANIFEST.in of Python Distutils, to specify the files to be obfuscated.
To create a project, use command init, use command info to show project information. config to update project settings, and build to obfuscate the scripts in the project.
Other commands, benchmark to metric performance, hdinfo to show hardware information, so that command licenses can generate license bind to fixed machine.
All the old commands capsule, encrypt, license are deprecated, and will be removed from v4.
A new document [src/user-guide.md](src/user-guide.md) is written for this new version.
- Remove unused files in distribute package
In this version, new obfuscate mode 7 and 8 are introduced. The main difference is that obfuscated script now is a normal python file (.py) other than compiled script (.pyc), so it can be used as common way.

- Fix issue: All the constant, co_names include function name, variable name etc still are in clear text. Refer to https://github.com/dashingsoft/pyarmor/issues/5
From this version, a new obfuscation mode is introduced. By this way, no import hooker, no setprofile, no settrace required. The performance of running or importing obfuscation python scripts has been remarkably improved. It’s significant for Pyarmor.
- Use this new mode as default way to obfuscate python scripts.
- Add new script “benchmark.py” to check performance in target machine: python benchmark.py
