0.13 (stable)
    1) Fix bug - sometimes generated warnging for trigger time (was undefined)
    2) Now a compute code can catch die with CHI::Cascade::Value object - this value
       will be returned from run method but value will not be saved in cache as
       computed value
    3) Improved a behavior with some buggy situations with cache (cache doesn't
       save a value by some reasons for example)
