What was most recent year AdaCore removed the “-gnat95” compiler switch?

And where to obtain for free?

The FSF GCC 14 compiler supports (gnatmake -h)

  -gnat83   Ada 83 mode
  -gnat95   Ada 95 mode
  -gnat2005 Ada 2005 mode
  -gnat2012 Ada 2012 mode (default)
  -gnat2022 Ada 2022 mode

Thanks Simon, good info for me,
