5.1.2

-----

5.1.1 insecure

-----
* Refine the procedure of encrypt script
* Reform module `pytransform.py`
* Fix issue: it will raise exception if no entry script when obfuscating scripts
* Fix issue: 'gbk' codec can't decode byte 0xa1 in position 28 (51)
* Add option `--upgrade` for command `capsule`
* Merge runtime files `pyshield.key`, `pyshield.lic` and `product.key` into `pytransform.key`

**Upgrade notes**

The capsule created in this version will include a new file
`pytransform.key` which is a replacement for 3 old runtime files:
`pyshield.key`, `pyshield.lic` and `product.key`.

The old capsule which created in the earlier version still works, it
stills use the old runtime files. But it's recommended to upgrade the
old capsule to new version. Just run this command::

pyarmor capsule --upgrade

All the license files generated for obfuscated scripts by old capsule
still work, but all the scripts need to be obfuscated again to take
new capsule effects.

Thanks to GNU lightning, from this version, the core routines are
protected by JIT technicals. That is to say, there is no binary code
in static file for core routines, they're generated in runtime.

Besides, the pre-built dynamic library for linux arm32/64 are packed
into the source package.

Fixed issues:

`AttributeError: '__main__' object has no attribute 'f'`

-----
This patch mainly changes webui, make it simple more:

* WebUI Packer: remove setup script, add output path, only support PyInstaller

4.4.1 insecure

-----
* Support Py2Installer by a simple way

* Set no restrict mode as default for new project and command `obfuscate`, `licenses`

4.4.0 insecure

-----

* Pack obfuscated scripts by command `pack`

In this version, introduces a new command `pack` used to pack
obfuscated scripts with `py2exe` and `cx_Freeze`. Once the setup
script of `py2exe` or `cx_Freeze` can bundle clear python scripts,
`pack` could pack obfuscated scripts by single command: `pyarmor
pack --type cx_Freeze /path/to/src/main.py`

* Pack obfuscated scripts by WebUI packer

WebUI is well reformed, simple and easy to use.

3.4

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.
