Version 0.21, but yes.  Since then a couple new architectures came out 
that aren't covered by that document (aarch64, risc-v, ppc64le come to 
mind), but they all use one of the two models from therein, and are 
usually described in their respective psABI documents.  But the basic 
handling of all TLS on Linux is fairly similar on all these architectures 
(also because these models are what gcc and glibc implements, and 
therefore is the easiest path to success for new architectures).


Ciao,
