Version compatibility

TRIQS version numbering

The TRIQS library has three-digit release numbers (e.g. 1.0.5) and two-digit version numbers (e.g. 1.0). The first two digits of the release number always correspond to the version number.

New releases within the same version correspond to bug fixes and improvements that do not change the API of the library. In other words, applications based on the TRIQS library do not need to be changed between such releases of the TRIQS library. Instead, a modification of the version number, say from 1.0 to 1.1, indicates deeper modifications of the library with possible breaks of the API. In that case, the source codes of the applications might need to be modified.

TRIQS applications version numbering

In order to easily identify which versions of an application are compatible with given versions of TRIQS, the applications follow a similar version numbering: three-digit release numbers and two-digit version numbers. The compatibility rule is then simply that an application is compatible with the TRIQS library if it has the same version number.

How to determine the version of the installed TRIQS library

In order to determine the version of an installed TRIQS library, you can either:

  • Read the content of the version.hpp file which is in the path_to_install_directory/include/triqs/ diretory.

  • Run pytriqs and type the following commands:

    from pytriqs.version import *
