We discuss the “generalized fluctuation-dissipation relations (theorems)” introduced for the first time in our works of 1977–1984 as statistical-thermodynamical consequences of time symmetry (reversibility) of microscopic dynamics. It is shown, in particular, that various similar relations, including the “fluctuation theorems”, that have appeared during and since the 1990s are essentially the alternative formulations or special cases of our old results.
