Release: 0.12.0-alpha (#772)

### Complex Numbers, Close & Backend Options This release adds data type support for complex numbers, allows to close iterations and adds first support for backend configuration options (via JSON), which are currently implemented for ADIOS2. Further installation options have been added (homebrew and CLI tool support with pip). New free standing functions and macro defines are provided for version checks. Thanks to @ax3l, @franzpoeschel, and @LDAmorim for contributing to this release! ## Which version am I running? ### Python ```python import openpmd_api print(openpmd_api.__version__) ``` ### C++ ```C++ #include <openPMD/openPMD.hpp> #include <iostream> int main() { // query compile-time macros: std::cout << OPENPMDAPI_VERSION_MAJOR << "." << OPENPMDAPI_VERSION_MINOR << "." << OPENPMDAPI_VERSION_PATCH << std::endl; // there is also: OPENPMDAPI_VERSION_LABEL (e.g. "alpha") // or query the runtime API (new): std::cout << openPMD::getVersion() << std::endl; return 0; } ``` ### CLI ```bash # new command line option: openpmd-ls --version ```
