FYI: master: NEWS: update

[Akim Demaille]

Pushed in master.

I’m quite tempted to say that this is 3.1.  Sure, there is still
plenty more we can do, but there are other releases to come.

If you have a different opinion, please say it!

+  Support for DJGPP, which have been unmaintained and untested for years, is

   Currently only GCC and Clang are supported.
 
+** Documentation
+
+*** A demonstration of variants
+
+  A new example was added (installed in .../share/doc/bison/examples),
+  'variant.yy', which shows how to use (Bison) variants in C++.
+
+  The other examples were made nicer to read.
+
+*** Some features are no longer 'experimental'
+
+  The following features, mature enough, are no longer flagged as
+  experimental in the documentation: push parsers, default %printer and
+  %destructor (typed: <*> and untyped: <>), %define api.value.type union and
+  variant, Java parsers, XML output, LR family (lr, ielr, lalr), and
+  semantic predicates (%?).

   The Intel compiler claims compatibility with GCC, yet rejects its _Pragma.
   Generated parsers now work around this.
 
+*** Various
+
+  There were several small fixes in the test suite and in the build system,
+  many warnings in bison and in the generated parsers were eliminated.  The
+  documentation also received its share of minor improvements.
+
+  Useless code was removed from C++ parsers, and some of the generated
+  constructors are more 'natural'.
