.. versionchanged:: 0.6.0
|

Rewrote recipe to support clang's build. The following changes has
|
|
been made:
|
|
|
|
- Bumped version number to 1.68.0
|
|
- Better version handling for url
|
|
- Added python 3 compatibility
|
|
- Default compiler for ndk's toolchain set to clang
|
|
- Python version will be detected via user-config.jam
|
|
- Changed stl's lib from ``gnustl_shared`` to ``c++_shared``
