GCC 6.1 release document sparse on Fortran details

[Damian Rouson]

All,

Did GCC 6.1 release on 2016-04-15?  I somehow missed the announcement.  

The description of the changes in the Fortran front end in 6.1 are very limited.  See https://gcc.gnu.org/gcc-6/changes.html.

Could someone please update the information there to include, for example, support for submodules and events and improved support for deferred-length character variables?
