commit 878a7c6d7e4a731a0da6f2fd8255e55b2cacbfe7

    Enable comparing versions containing git hashes and more
    
    Distributions like SLES, use time stamps and git hashes between
    version and release, e.g.: 2.0.3+20200128.df6c286d9-1.281. To support
    such patterns and keep compatibility with other formats, a new regex
    is used in osc_is_ver() and the 'awk' built-in functions were
    deprecated (ocf_ver2num(), ocf_ver_level(), ocf_ver_complete_level())
    in favor of sort(1) using keydef in ocf_version_cmp()
