Changes in 1.9.0:
* New modules (see the manual for details)
+** `(srfi srfi-18)', multithreading support
** The `(ice-9 i18n)' module provides internationalization support
* Changes to the distribution
* Changes to the C interface
+** The GH interface (deprecated in version 1.6, 2001) was removed.
+
+** Internal `scm_i_' functions now have "hidden" linkage with GCC/ELF
+
+This makes these internal functions technically not callable from
+application code.
+
** Functions for handling `scm_option' now no longer require an argument
indicating length of the `scm_t_option' array.
+** Primitive procedures (aka. "subrs") are now stored in double cells
+This removes the subr table and simplifies the code.
+
+** Primitive procedures with more than 3 arguments (aka. "gsubrs") are
+no longer implemented using the "compiled closure" mechanism. This
+simplifies code and reduces both the storage and run-time overhead.
+

+Changes in 1.8.7 (since 1.8.6)
+
+* Bugs fixed
+
+** Fix compilation with `--disable-deprecated'
+** Fix %fast-slot-ref/set!, to avoid possible segmentation fault
+** Fix MinGW build problem caused by HAVE_STRUCT_TIMESPEC confusion
+** Fix build problem when scm_t_timespec is different from struct timespec
+** Fix build when compiled with -Wundef -Werror
+
+** Allow @ macro to work with (ice-9 syncase)
+
+Previously, use of the @ macro in a module whose code is being
+transformed by (ice-9 syncase) would cause an "Invalid syntax" error.
+Now it works as you would expect (giving the value of the specified
+module binding).
+
+** Have `scm_take_locale_symbol ()' return an interned symbol (bug #25865)
+
+\f
+Changes in 1.8.6 (since 1.8.5)
+
+* New features (see the manual for details)
+
+** New convenience function `scm_c_symbol_length ()'
+
+** Single stepping through code from Emacs
+
+When you use GDS to evaluate Scheme code from Emacs, you can now use
+`C-u' to indicate that you want to single step through that code. See
+`Evaluating Scheme Code' in the manual for more details.
+
+** New "guile(1)" man page!
+
+* Changes to the distribution
+
+** Automake's `AM_MAINTAINER_MODE' is no longer used
+
+Thus, the `--enable-maintainer-mode' configure option is no longer
+available: Guile is now always configured in "maintainer mode".
+
+** `ChangeLog' files are no longer updated
+
+Instead, changes are detailed in the version control system's logs. See
+the top-level `ChangeLog' files for details.
+
+
+* Bugs fixed
+
+** `symbol->string' now returns a read-only string, as per R5RS
+** Fix incorrect handling of the FLAGS argument of `fold-matches'
+** `guile-config link' now prints `-L$libdir' before `-lguile'
+** Fix memory corruption involving GOOPS' `class-redefinition'
+** Fix possible deadlock in `mutex-lock'
+** Fix build issue on Tru64 and ia64-hp-hpux11.23 (`SCM_UNPACK' macro)
+** Fix build issue on mips, mipsel, powerpc and ia64 (stack direction)
+** Fix build issue on hppa2.0w-hp-hpux11.11 (`dirent64' and `readdir64_r')
+** Fix build issue on i386-unknown-freebsd7.0 ("break strict-aliasing rules")
+** Fix misleading output from `(help rationalize)'
+** Fix build failure on Debian hppa architecture (bad stack growth detection)
+** Fix `gcd' when called with a single, negative argument.
+** Fix `Stack overflow' errors seen when building on some platforms
+** Fix bug when `scm_with_guile ()' was called several times from the
+ same thread
+** The handler of SRFI-34 `with-exception-handler' is now invoked in the
+ dynamic environment of the call to `raise'
+** Fix potential deadlock in `make-struct'
+** Fix compilation problem with libltdl from Libtool 2.2.x
+** Fix sloppy bound checking in `string-{ref,set!}' with the empty string
\f
Changes in 1.8.5 (since 1.8.4)
+* Infrastructure changes
+
+** Guile repository switched from CVS to Git
+
+The new repository can be accessed using
+"git-clone git://git.sv.gnu.org/guile.git", or can be browsed on-line at
+http://git.sv.gnu.org/gitweb/?p=guile.git . See `README' for details.
+
+** Add support for `pkg-config'
+
+See "Autoconf Support" in the manual for details.
+
+* New modules (see the manual for details)
+
+** `(srfi srfi-88)'
+
+* New features (see the manual for details)
+
+** New `postfix' read option, for SRFI-88 keyword syntax
+** Some I/O primitives have been inlined, which improves I/O performance
+** New object-based traps infrastructure
+
+This is a GOOPS-based infrastructure that builds on Guile's low-level
+evaluator trap calls and facilitates the development of debugging
+features like single-stepping, breakpoints, tracing and profiling.
+See the `Traps' node of the manual for details.
+
+** New support for working on Guile code from within Emacs
+
+Guile now incorporates the `GDS' library (previously distributed
+separately) for working on Guile code from within Emacs. See the
+`Using Guile In Emacs' node of the manual for details.
+
* Bugs fixed
** `scm_add_slot ()' no longer segfaults (fixes bug #22369)
Previously, expressions like `(match '((foo) (bar)) (((_ ...) ...) #t))'
would trigger an unbound variable error for `match:andmap'.
+** `(oop goops describe)' now properly provides the `describe' feature
+** Fixed `args-fold' from `(srfi srfi-37)'
+
+Previously, parsing short option names of argument-less options would
+lead to a stack overflow.
+
+** `(srfi srfi-35)' is now visible through `cond-expand'
+** Fixed type-checking for the second argument of `eval'
+** Fixed type-checking for SRFI-1 `partition'
+** Fixed `struct-ref' and `struct-set!' on "light structs"
+** Honor struct field access rights in GOOPS
+** Changed the storage strategy of source properties, which fixes a deadlock
+** Allow compilation of Guile-using programs in C99 mode with GCC 4.3 and later
** Fixed build issue for GNU/Linux on IA64
-** Fixed build issue on NetBSD 1.6
+** Fixed build issues on NetBSD 1.6
+** Fixed build issue on Solaris 2.10 x86_64
+** Fixed build issue with DEC/Compaq/HP's compiler
+** Fixed `scm_from_complex_double' build issue on FreeBSD
+** Fixed `alloca' build issue on FreeBSD 6
+** Removed use of non-portable makefile constructs
+** Fixed shadowing of libc's <random.h> on Tru64, which broke compilation
+** Make sure all tests honor `$TMPDIR'
+
+* Changes to the distribution
+
+** New FAQ
+
+We've started collecting Frequently Asked Questions (FAQ), and will
+distribute these (with answers!) in future Guile releases.

Changes in 1.8.4 (since 1.8.3)
** The reader is now faster, which reduces startup time
** Procedures returned by `record-accessor' and `record-modifier' are faster
-
\f
Changes in 1.8.2 (since 1.8.1):
** set-program-arguments
** make-vtable
+* Incompatible changes
+
+** The body of a top-level `define' no longer sees the binding being created
+
+In a top-level `define', the binding being created is no longer visible
+from the `define' body. This breaks code like
+"(define foo (begin (set! foo 1) (+ foo 1)))", where `foo' is now
+unbound in the body. However, such code was not R5RS-compliant anyway,
+per Section 5.2.1.
+
* Bugs fixed
** Fractions were not `equal?' if stored in unreduced form.
** scm_exp - [C]
** scm_sqrt - [C]
-* New `(ice-9 i18n)' module (see the manual for details)
-
* Bugs fixed
** Build problems have been fixed on MacOS, SunOS, and QNX.
