* Noteworthy changes in release ?.? (????-??-??) [?]
A new mailing list was created, Bison Announce. It is low traffic, and is
only about announcing new releases and important messages (e.g., polls about
major decisions to make).
* Noteworthy changes in release 3.2.91 (2019-01-19) [beta]
https://lists.gnu.org/mailman/listinfo/bison-announce
** Backward incompatible changes
Support for DJGPP, which has been unmaintained and untested for years, is
removed.
** Deprecated features
A new feature, --update (see below) helps adjusting existing grammars to
deprecations.
*** Deprecated directives
The %error-verbose directive is deprecated in favor of '%define
parse.error verbose' since Bison 3.0, but no warning was issued.
The '%name-prefix "xx"' directive is deprecated in favor of '%define
api.prefix {xx}' since Bison 3.0, but no warning was issued. These
directives are slightly different, you might need to adjust your code.
%name-prefix renames only symbols with external linkage, while api.prefix
also renames types and macros, including YYDEBUG, YYTOKENTYPE,
yytokentype, YYSTYPE, YYLTYPE, etc.
Users of Flex that move from '%name-prefix "xx"' to '%define api.prefix
{xx}' will typically have to update YY_DECL from
#define YY_DECL int xxlex (YYSTYPE *yylval, YYLTYPE *yylloc)
to
#define YY_DECL int xxlex (XXSTYPE *yylval, XXLTYPE *yylloc)
*** Deprecated %define variable names
The following variables, mostly related to parsers in Java, have been
renamed for consistency. Backward compatibility is ensured, but upgrading
is recommended.
abstract -> api.parser.abstract
annotations -> api.parser.annotations
extends -> api.parser.extends
final -> api.parser.final
implements -> api.parser.implements
parser_class_name -> api.parser.class
public -> api.parser.public
strictfp -> api.parser.strictfp

*** Bison is now relocatable
If you pass '--enable-relocatable' to 'configure', Bison is relocatable.
A relocatable program can be moved or copied to a different location on
the file system. It can also be used through mount points for network
sharing. It is possible to make symlinks to the installed and moved
programs, and invoke them through the symlink.
