The C90 edition of the ISO C standard will never be changed by
ISO.  The C90 language could be extended by some independent
party.

No, they aren't, and no, they weren't.  C90, both the language
and the document that defines it, are not obsolete, but still in
use.  The same applies to C99 and C11.

The ISO C standard doesn't say anything about making earlier
editions obsolete.  The language used in the ISO C standard is
that each edition cancels and replaces the previous edition as
being the current ISO C standard.  At any one time there is only
one ISO C standard.  But changing which edition corresponds to
the current ISO standard doesn't change the status of the earlier
documents, or of the language they describe.  And in particular,
because they are all still in use, they are not obsolete.
