@ -8,86 +8,7 @@ Please send Guile bug reports to bug-guile@gnu.org.
(During the 1.9 series, we will keep an incremental NEWS for the latest
prerelease, and a full NEWS corresponding to 1.8 -> 2.0.)
Changes in 1.9.9 (since the 1.9.8 prerelease):
** Faster dynamic binding with fluids
`fluid-ref' and `fluid-set' now have dedicated bytecode instructions.
Dynamic binding via `with-fluids' or `with-fluids*' no longer causes
recursive VM invocations, nor closure allocation of the body. Unused
fluid numbers are now garbage-collected.
** Incompatible Tree-IL changes
There were a number of incompatible changes made in the last cycle
regarding Tree-IL, Guile's high-level intermediate language. See the
change logs for details. If these affected you, clearly you need to
submit your compiler patches upstream!
** Prompts: Delimited, composable continuations
Guile now has prompts as part of its primitive language. See "Prompts"
in the manual, for more information.
Expressions entered in at the REPL, or from the command line, are
surrounded by a prompt with the default prompt tag.
** Deprecated: `lazy-catch'
`lazy-catch' was a form that captured the stack at the point of a
`throw', but the dynamic state at the point of the `catch'. It was a bit
crazy. Please change to use `catch', possibly with a throw-handler, or
`with-throw-handler'.
** `catch', `throw', `with-throw-handler' implemented in Scheme
This doesn't have any end-user impact, but we're so proud of being able
to implement these constructs in terms of prompts and fluids, while not
changing the user API, that we need to mention it in the NEWS. Thanks
for reading!
** Current-module tracking in the syntax expander
Expanding a `begin' expression that changed the current module via an
`eval-when' wasn't working, due to a bug. This was fixed.
** Backtraces at the REPL don't show REPL frames
The 1.9 series has had overly verbose backtraces, which showed frames
internal to the implementation of the REPL. This has been mostly fixed.
Please report bugs to bug-guile@gnu.org.
** Additions to the foreign function interface (FFI)
The `(system foreign)' module now provides additional foreign types
corresponding to C's `int', `long', `size_t', etc.
In addition, the `dynamic-link' procedure can now be called without any
argument, in which case it returns a "global symbol handle", allowing
symbols currently available to the program to be looked up.
** Documentation of `syntax-rules' macros
The documentation of macros in the manual is now separate from that of
procedures. A new section on `syntax-rules' macros has been added.
** Effective version bump to 2.0
Guile has had an "effective version" for some time, typically generated
as "MAJOR-VERSION.MINOR-VERSION". This release decouples the effective
version from the actual version, setting it prematurely to 2.0. This
should shake out any version-related distribution bugs.
** Parallel installability fixes
Guile now installs its header files to a effective-version-specific
directory, and includes the effective version (e.g. 2.0) in the library
name (e.g. libguile-2.0.so).
This change should be transparent to users, who should detect Guile via
the guile.m4 macro, or the guile-2.0.pc pkg-config file. It will allow
parallel installs for multiple versions of Guile development
environments.
Changes in 1.9.10 (since the 1.9.9 prerelease):
** And of course, the usual collection of bugfixes
@ -642,6 +563,11 @@ environment as well: `syntax->datum', `datum->syntax',
`bound-identifier=?', `free-identifier=?', `generate-temporaries',
`identifier?', and `syntax-violation'. See the R6RS for documentation.
** Documentation of `syntax-rules' and `syntax-case' macros
The documentation of macros in the manual is now separate from that of
procedures. A new section on hygienic macros has been added.
** Tail patterns in syntax-case
Guile has pulled in some more recent changes from the psyntax portable
