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
** Duplicate bindings among used modules are resolved lazily.
This slightly improves program startup times.
+** New thread cancellation and thread cleanup API
+See `cancel-thread', `set-thread-cleanup!', and `thread-cleanup'.
+
* 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.
+\f
+Changes in 1.8.7 (since 1.8.6)
+
+* Bugs fixed
+
+** Fix %fast-slot-ref/set!, to avoid possible segmentation fault
+
+\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+** `ChangeLog' files are no longer updated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)
+** Fixed `(ice-9 match)' for patterns like `((_ ...) ...)'
+
+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 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)
* Bugs fixed
** CR (ASCII 0x0d) is (again) recognized as a token delimiter by the reader
+** Fixed a segmentation fault which occurred when displaying the
+backtrace of a stack with a promise object (made by `delay') in it.
+** Make `accept' leave guile mode while blocking
+** `scm_c_read ()' and `scm_c_write ()' now type-check their port argument
+** Fixed a build problem on AIX (use of func_data identifier)
+** Fixed a segmentation fault which occurred when hashx-ref or hashx-set! was
+called with an associator proc that returns neither a pair nor #f.
+** Secondary threads now always return a valid module for (current-module).
+** Avoid MacOS build problems caused by incorrect combination of "64"
+system and library calls.
+** `guile-snarf' now honors `$TMPDIR'
+** `guile-config compile' now reports CPPFLAGS used at compile-time
+** Fixed build with Sun Studio (Solaris 9)
+** Fixed wrong-type-arg errors when creating zero length SRFI-4
+uniform vectors on AIX.
+** Fixed a deadlock that occurs upon GC with multiple threads.
+** Fixed compile problem with GCC on Solaris and AIX (use of _Complex_I)
+** Fixed autotool-derived build problems on AIX 6.1.
+** Fixed NetBSD/alpha support
+** Fixed MacOS build problem caused by use of rl_get_keymap(_name)
+
+* New modules (see the manual for details)
+
+** `(srfi srfi-69)'
+
+* Documentation fixes and improvements
+
+** Removed premature breakpoint documentation
+
+The features described are not available in the series of 1.8.x
+releases, so the documentation was misleading and has been removed.
+
+** More about Guile's default *random-state* variable
+
+** GOOPS: more about how to use `next-method'
+
+* Changes to the distribution
+
+** Corrected a few files that referred incorrectly to the old GPL + special exception licence
+
+In fact Guile since 1.8.0 has been licensed with the GNU Lesser
+General Public License, and the few incorrect files have now been
+fixed to agree with the rest of the Guile distribution.
+
+** Removed unnecessary extra copies of COPYING*
+
+The distribution now contains a single COPYING.LESSER at its top level.
\f
Changes in 1.8.3 (since 1.8.2)
** 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.
