Please send Guile bug reports to bug-guile@gnu.org.
-Changes in 2.0.1 (since 2.0.0):
+Changes in 2.0.3 (since 2.0.2):
+* Speed improvements
+** Guile has a new optimizer, `peval'.
-* New modules (see the manual for details)
+`Peval' is a partial evaluator that performs constant folding, dead code
+elimination, copy propagation, and inlining. By default it runs on
+every piece of code that Guile compiles, to fold computations that can
+happen at compile-time, so they don't have to happen at runtime.
-** `(ice-9 binary-ports)', XXX
-
-* Memory leak fixes
+If we did our job right, the only impact you would see would be your
+programs getting faster. But if you notice slowdowns or bloated code,
+please send a mail to bug-guile@gnu.org with details.
-close-port leaking iconv_t
+Thanks to William R. Cook, Oscar Waddell, and Kent Dybvig for inspiring
+peval and its implementation.
-weak hash table pumping
+You can see what peval does on a given piece of code by running the new
+`,optimize' REPL meta-command, and comparing it to the output of
+`,expand'. See "Compile Commands" in the manual, for more.
-* doc work
+** Fewer calls to `stat'.
-goops mop
+Guile now stats only the .go file and the .scm file when loading a fresh
+compiled file.
-* guile.m4 supports linking with rpath
-
- * guile.m4 (GUILE_FLAGS): Also set GUILE_LIBS and GUILE_LTLIBS. Fix
- documentation.
+* Notable changes
-* Add omitted exports from `(ice-9 vlist)'.
-
- * module/ice-9/vlist.scm: Export `vhash-delq' and `vhash-delv'.
+** New module: `(web client)', a simple synchronous web client.
-* re-enable the after-gc-hook
-
-* chi-top-sequence defines macros before expanding other exps
-
-(begin
- (define even?
- (lambda (x)
- (or (= x 0) (odd? (- x 1)))))
- (define-syntax odd?
- (syntax-rules ()
- ((odd? x) (not (even? x)))))
- (even? 10))
+See "Web Client" in the manual, for more.
-* flush all input on a read error
-
- * module/system/repl/repl.scm (flush-all-input): New helper.
- (prompting-meta-read): Flush all input on a read error, as we could be
- within some expression or a string or something.
+** Users can now install compiled `.go' files.
+
+See "Installing Site Packages" in the manual.
-* repl.scm understands comments
+** Remove Front-Cover and Back-Cover text from the manual.
- * module/system/repl/repl.scm (read-comment, read-scheme-line-comment)
- (read-scheme-datum-comment): New helpers.
- (meta-reader): Take a language instead of a reader. If we have a
- nonwhitespace char, first check to see that it's a comment, and if so,
- read it off and loop.
- (prompting-meta-read): Call meta-reader with the lang.
-
-* Add ,width meta-command to set screen width in debug output
+The manual is still under the GNU Free Documentation License, but no
+longer has any invariant sections.
+
+** More helpful `guild help'.
-terminal-width by default
+`guild' is Guile's multi-tool, for use in shell scripting. Now it has a
+nicer interface for querying the set of existing commands, and getting
+help on those commands. Try it out and see!
-* man page updates
+** New macro: `define-syntax-rule'
-Mark Harig
+`define-syntax-rule' is a shorthand to make a `syntax-rules' macro with
+one clause. See "Syntax Rules" in the manual, for more.
-* add ice-9 eval-string
-
-Fly Evaluation in the manual
+** The `,time' REPL meta-command now has more precision.
+
+The output of this command now has microsecond precision, instead of
+10-millisecond precision.
-* add scm_c_public_ref et al
+** `(ice-9 match)' can now match records.
- * libguile/modules.h:
- * libguile/modules.c (scm_public_lookup, scm_private_lookup)
- (scm_c_public_lookup, scm_c_private_lookup, scm_public_ref)
- (scm_private_ref, scm_c_public_ref, scm_c_private_ref)
- (scm_public_variable, scm_private_variable, scm_c_public_variable)
- (scm_c_private_variable): New helpers to get at variables and values
- in modules.
+See "Pattern Matching" in the manual, for more on matching records.
-"Accessing Modules from C" in the manual
+** New module: `(language tree-il debug)'.
-* add scm_call_{5,6}
-
- * doc/ref/api-evaluation.texi (Fly Evaluation): Document
- scm_call_{5,6,n}.
+This module provides a tree-il verifier. This is useful for people that
+generate tree-il, usually as part of a language compiler.
-* Add scm_from_latin1_keyword and scm_from_utf8_keyword
+** New functions: `scm_is_exact', `scm_is_inexact'.
- * doc/ref/api-data.texi: Document new functions. Remind users that
- scm_from_locale_keyword should not be used when the name is a C string
- constant. Change formal parameter from `str' to `name'.
+These provide a nice C interface for Scheme's `exact?' and `inexact?',
+respectively.
-* srfi-9 define-record-type in nested contexts
+* Bugs fixed
-* Add `get-string-n' and `get-string-n!' for binary and R6RS ports
+See the git log (or the ChangeLog) for more details on these bugs.
+
+** Fix order of importing modules and resolving duplicates handlers.
+** Fix a number of bugs involving extended (merged) generics.
+** Fix invocation of merge-generics duplicate handler.
+** Fix write beyond array end in arrays.c.
+** Fix read beyond end of hashtable size array in hashtab.c.
+** (web http): Locale-independent parsing and serialization of dates.
+** Ensure presence of Host header in HTTP/1.1 requests.
+** Fix take-right and drop-right for improper lists.
+** Fix leak in get_current_locale().
+** Fix recursive define-inlinable expansions.
+** Check that srfi-1 procedure arguments are procedures.
+** Fix r6rs `map' for multiple returns.
+** Fix scm_tmpfile leak on POSIX platforms.
+** Fix a couple of leaks (objcode->bytecode, make-boot-program).
+** Fix guile-lib back-compatibility for module-stexi-documentation.
+** Fix --listen option to allow other ports.
+** Fix scm_to_latin1_stringn for substrings.
+** Fix compilation of untyped arrays of rank not 1.
+** Fix unparse-tree-il of <dynset>.
+** Fix reading of #||||#.
+** Fix segfault in GOOPS when class fields are redefined.
+** Prefer poll(2) over select(2) to allow file descriptors above FD_SETSIZE.
-* rnrs io ports work
+\f
+Changes in 2.0.2 (since 2.0.1):
-Export `current-input-port', `current-output-port' and
-`current-error-port'.
-
- Enhance transcoder-related functionality of `(rnrs io ports)'
-
- * module/rnrs/io/ports.scm (transcoder-eol-style)
- (transcoder-error-handling-mode): Export these.
- (textual-port?): Implement this procedure and export it.
- * module/rnrs.scm: Export these here as well.
+* Notable changes
+
+** `guile-tools' renamed to `guild'
- * module/rnrs/io/ports.scm (port-transcoder): Implement this procedure.
- (binary-port?): Treat only ports without an encoding as binary ports,
- add docstring.
- (standard-input-port, standard-output-port, standard-error-port):
- Ensure these are created without an encoding.
- (eol-style): Add `none' as enumeration member.
- (native-eol-style): Switch to `none' from `lf'.
+The new name is shorter. Its intended future use is for a CPAN-like
+system for Guile wizards and journeyfolk to band together to share code;
+hence the name. `guile-tools' is provided as a backward-compatible
+symbolic link. See "Using Guile Tools" in the manual, for more.
+
+** New control operators: `shift' and `reset'
- * test-suite/tests/r6rs-ports.test (7.2.7 Input ports)
- (8.2.10 Output ports): Test binary-ness of `standard-input-port',
- `standard-output-port' and `standard-error-port'.
- (8.2.6 Input and output ports): Add test for `port-transcoder'.
+See "Shift and Reset" in the manual, for more information.
+
+** `while' as an expression
- doc: Remove "lack of support for Unicode I/O and strings".
+Previously the return value of `while' was unspecified. Now its
+values are specified both in the case of normal termination, and via
+termination by invoking `break', possibly with arguments. See "while
+do" in the manual for more.
+
+** Disallow access to handles of weak hash tables
- * doc/ref/api-io.texi (R6RS I/O Ports): Remove 1.8ish comment.
+`hash-get-handle' and `hash-create-handle!' are no longer permitted to
+be called on weak hash tables, because the fields in a weak handle could
+be nulled out by the garbage collector at any time, but yet they are
+otherwise indistinguishable from pairs. Use `hash-ref' and `hash-set!'
+instead.
-* add pointer->scm, scm->pointer
+** More precision for `get-internal-run-time', `get-internal-real-time'
- * libguile/foreign.c (scm_pointer_to_scm, scm_scm_to_pointer): New
- functions, useful to pass and receive SCM values to and from foreign
- functions.
+On 64-bit systems which support POSIX clocks, Guile's internal timing
+procedures offer nanosecond resolution instead of the 10-millisecond
+resolution previously available. 32-bit systems now use 1-millisecond
+timers.
+
+** Guile now measures time spent in GC
- * module/system/foreign.scm: Export the new functions.
+`gc-stats' now returns a meaningful value for `gc-time-taken'.
+
+** Add `gcprof'
- * doc/ref/api-foreign.texi (Foreign Variables): Add docs.
+The statprof profiler now exports a `gcprof' procedure, driven by the
+`after-gc-hook', to see which parts of your program are causing GC. Let
+us know if you find it useful.
-* gc-stats update
+** `map', `for-each' and some others now implemented in Scheme
-add heap-allocated-since-gc; fix ,stat.
-
-* allow ,option on-error report instead of debug
-
-"System Commands" in the manual.
+We would not mention this in NEWS, as it is not a user-visible change,
+if it were not for one thing: `map' and `for-each' are no longer
+primitive generics. Instead they are normal bindings, which can be
+wrapped by normal generics. This fixes some modularity issues between
+core `map', SRFI-1 `map', and GOOPS.
-* Make VM string literals immutable.
-
-* don't redirect pthread_create et al
+Also it's pretty cool that we can do this without a performance impact.
- * libguile/bdw-gc.h: Don't do pthread redirects, because we don't want
- to affect applications' pthread_* bindings.
+** Add `scm_peek_byte_or_eof'.
- * libguile/pthread-threads.h (scm_i_pthread_create)
- (scm_i_pthread_detach, scm_i_pthread_exit, scm_i_pthread_cancel)
- (scm_i_pthread_sigmask): Do pthread redirects here, in this internal
- header.
+This helper is like `scm_peek_char_or_eof', but for bytes instead of
+full characters.
-* Document SRFI-23
+** Implement #:stop-at-first-non-option option for getopt-long
- * doc/ref/srfi-modules.texi: mention that we support SRFI 23
- * module/ice-9/boot-9.scm (%cond-expand-features): add srfi-23
+See "getopt-long Reference" in the manual, for more information.
-* with-continuation-barrier calls exit(3) _after_ unwinding
+** Improve R6RS conformance for conditions in the I/O libraries
- * libguile/continuations.c (scm_handler, c_handler)
- (scm_c_with_continuation_barrier, scm_with_continuation_barrier):
- Instead of calling scm_handle_by_message_noexit in the pre-unwind
- handler, roll our own exception printing in the pre-unwind, and do to
- exit()-on-quit in the post-unwind handler. This lets the stack unwind
- at exit-time so that pending dynwinds run.
-
- * test-suite/tests/continuations.test ("continuations"): Add a test.
+The `(rnrs io simple)' module now raises the correct R6RS conditions in
+error cases. `(rnrs io ports)' is also more correct now, though it is
+still a work in progress.
-* string->pointer and pointer->string have optional encoding arg
+** All deprecated routines emit warnings
-"Void Pointers and Byte Access" in the manual.
+A few deprecated routines were lacking deprecation warnings. This has
+been fixed now.
-* Several optimizations for R6RS fixnum arithmetic
-
-* Move `define-inlinable' into the default namespace
-
- * module/ice-9/boot-9.scm (define-inlineable): Moved here from SRFI-9.
- * module/srfi/srfi-9 (define-inlinable): Removed here.
-
- * doc/ref/api-procedures.texi (Inlinable Procedures): Add subsection
- about `define-inlinable'.
+* Speed improvements
-* Implement R6RS' `fixnum?' in a smarter way
-
- * module/rnrs/arithmetic/fixnums.scm (fixnum?): Implemented using
- bit-twiddling, and using `define-inlinable'.
+** Constants in compiled code now share state better
-commit 882c89636a2a4afa26cff17c7cdbc1d8c1cb2745
-Author: Mark H Weaver <mhw@netris.org>
-Date: Wed Apr 6 15:09:42 2011 -0400
+Constants with shared state, like `("foo")' and `"foo"', now share state
+as much as possible, in the entire compilation unit. This cuts compiled
+`.go' file sizes in half, generally, and speeds startup.
- Fix the R6RS exact-integer-sqrt and import into core guile
-
- * libguile/numbers.c (scm_exact_integer_sqrt): New C procedure to
- compute exact integer square root and remainder.
- (scm_i_exact_integer_sqrt): New Scheme procedure `exact-integer-sqrt'
- from the R6RS, imported into core guile.
+** VLists: optimize `vlist-fold-right', and add `vhash-fold-right'
+
+These procedures are now twice as fast as they were.
+
+** UTF-8 ports to bypass `iconv' entirely
- * libguile/numbers.h: Add prototypes.
+This reduces memory usage in a very common case.
+
+** Compiler speedups
+
+The compiler is now about 40% faster. (Note that this is only the case
+once the compiler is itself compiled, so the build still takes as long
+as it did before.)
+
+** VM speed tuning
- * module/rnrs/base.scm: Remove broken stub implementation, which would
- fail badly when applied to large integers.
+Some assertions that were mostly useful for sanity-checks on the
+bytecode compiler are now off for both "regular" and "debug" engines.
+This together with a fix to cache a TLS access and some other tweaks
+improve the VM's performance by about 20%.
+
+** SRFI-1 list-set optimizations
+
+lset-adjoin and lset-union now have fast paths for eq? sets.
+
+** `memq', `memv' optimizations
+
+These procedures are now at least twice as fast than in 2.0.1.
+
+* Deprecations
+
+** Deprecate scm_whash API
- * doc/ref/api-data.texi: Add documentation.
+`scm_whash_get_handle', `SCM_WHASHFOUNDP', `SCM_WHASHREF',
+`SCM_WHASHSET', `scm_whash_create_handle', `scm_whash_lookup', and
+`scm_whash_insert' are now deprecated. Use the normal hash table API
+instead.
+
+** Deprecate scm_struct_table
- * doc/ref/r6rs.texi: Change documentation for `exact-integer-sqrt' to a
- stub that xrefs the core docs, as is done for other operations
- available in core.
+`SCM_STRUCT_TABLE_NAME', `SCM_SET_STRUCT_TABLE_NAME',
+`SCM_STRUCT_TABLE_CLASS', `SCM_SET_STRUCT_TABLE_CLASS',
+`scm_struct_table', and `scm_struct_create_handle' are now deprecated.
+These routines formed part of the internals of the map between structs
+and classes.
+
+** Deprecate scm_internal_dynamic_wind
- * test-suite/tests/numbers.test: Add tests.
+The `scm_t_inner' type and `scm_internal_dynamic_wind' are deprecated,
+as the `scm_dynwind' API is better, and this API encourages users to
+stuff SCM values into pointers.
+
+** Deprecate scm_immutable_cell, scm_immutable_double_cell
- * NEWS: Add news entries.
+These routines are deprecated, as the GC_STUBBORN API doesn't do
+anything any more.
+
+* Manual updates

+** Fix double-loading of script in -ds case
+** -x error message fix
+** iconveh-related cross-compilation fixes
+** Fix small integer return value packing on big endian machines.
+** Fix hash-set! in weak-value table from non-immediate to immediate
+** Fix call-with-input-file & relatives for multiple values
+** Fix `hash' for inf and nan
+** Fix libguile internal type errors caught by typing-strictness==2
+** Fix compile error in MinGW fstat socket detection
+** Fix generation of auto-compiled file names on MinGW

+** Fix unaligned accesses for bytevectors of complex numbers
+** Fix '(a #{.} b)
+** Fix erroneous VM stack overflow for canceled threads
- * module/system/repl/server.scm (run-server): Ignore SIGPIPE when we run
- a server, as otherwise a rudely disconnected client could cause the
- server to quit. Thanks to John Proctor for the report, and Detlev
- Zundel for the debugging.

+Changes in 2.0.1 (since 2.0.0):
-commit 15671c6e7fd86160b415b5373b2c1539e23556f3
-Author: Andy Wingo <wingo@pobox.com>
-Date: Mon Apr 11 11:52:35 2011 +0200
+* Notable changes
- refactor scm_i_print_symbol_name
+** guile.m4 supports linking with rpath
- * libguile/print.c (symbol_has_extended_read_syntax)
- (print_normal_symbol, print_extended_symbol, scm_i_print_symbol_name):
- Factor scm_i_print_symbol_name into separate routines. Add comments.
- There are a number of bugs here.
+The GUILE_FLAGS macro now sets GUILE_LIBS and GUILE_LTLIBS, which
+include appropriate directives to the linker to include libguile-2.0.so
+in the runtime library lookup path.
+
+** `begin' expands macros in its body before other expressions
+
+This enables support for programs like the following:
-commit d9527cfafdad1046770437a7a59d3745e7243c67
-Author: Andy Wingo <wingo@pobox.com>
-Date: Mon Apr 11 12:48:06 2011 +0200
+ (begin
+ (define even?
+ (lambda (x)
+ (or (= x 0) (odd? (- x 1)))))
+ (define-syntax odd?
+ (syntax-rules ()
+ ((odd? x) (not (even? x)))))
+ (even? 10))
- read-extended-symbol handles backslash better, including r6rs hex escapes
+** REPL reader usability enhancements
+
+The REPL now flushes input after a read error, which should prevent one
+error from causing other errors. The REPL also now interprets comments
+as whitespace.
+
+** REPL output has configurable width
+
+The REPL now defaults to output with the current terminal's width, in
+columns. See "Debug Commands" in the manual for more information on
+the ,width command.
+
+** Better C access to the module system
+
+Guile now has convenient C accessors to look up variables or values in
+modules and their public interfaces. See `scm_c_public_ref' and friends
+in "Accessing Modules from C" in the manual.
+
+** Added `scm_call_5', `scm_call_6'
- * libguile/read.c (scm_read_extended_symbol): Interpret '\' as an escape
- character. Due to some historical oddities we have to support '\'
- before any character, but since we never emitted '\' in front of
- "normal" characters like 'x' we can interpret "\x..;" to be an R6RS
- hex escape.
+See "Fly Evaluation" in the manual.
+
+** Added `scm_from_latin1_keyword', `scm_from_utf8_keyword'
- * test-suite/tests/reader.test ("#{}#"): Add tests.
+See "Keyword Procedures" in the manual, for more. Note that
+`scm_from_locale_keyword' should not be used when the name is a C string
+constant.
+
+** R6RS unicode and string I/O work
-commit 2e9fc9fc73a8157152e6b2e122ec545d96478c2a
-Author: Andy Wingo <wingo@pobox.com>
-Date: Mon Apr 11 13:38:27 2011 +0200
+Added efficient implementations of `get-string-n' and `get-string-n!'
+for binary ports. Exported `current-input-port', `current-output-port'
+and `current-error-port' from `(rnrs io ports)', and enhanced support
+for transcoders.
- symbols with odd characters print better in #{}#
+** Added `pointer->scm', `scm->pointer' to `(system foreign)'
- * libguile/print.c (symbol_has_extended_read_syntax): Use a more
- general, unicode-appropriate algorithm. Hopefully doesn't cause
- any current #{}# cases to be unescaped.
- (print_extended_symbol): Use more appropriate unicode algorithm, and
- emit unicode hex escapes instead of our own lame escapes.
+These procedure are useful if one needs to pass and receive SCM values
+to and from foreign functions. See "Foreign Variables" in the manual,
+for more.
- * test-suite/tests/symbols.test: Add tests.
+** Added `heap-allocated-since-gc' to `(gc-stats)'
-commit b9e22602bb9c7d82500e4e5612bf80e478e28b8c
-Author: Andy Wingo <wingo@pobox.com>
-Date: Mon Apr 11 13:49:29 2011 +0200
-
- regen psyntax-pp.scm
+Also fixed the long-standing bug in the REPL `,stat' command.
+
+** Add `on-error' REPL option
- * module/ice-9/psyntax-pp.scm: Regenerate, to take advantage of better
- #{}# serialization.
+This option controls what happens when an error occurs at the REPL, and
+defaults to `debug', indicating that Guile should enter the debugger.
+Other values include `report', which will simply print a backtrace
+without entering the debugger. See "System Commands" in the manual.
-commit 62ef23cbb828accf1f5b9622ff17775aa539d354
-Author: Andy Wingo <wingo@pobox.com>
-Date: Mon Apr 11 17:21:20 2011 +0200
+** Enforce immutability of string literals
- fix reader.test for --disable-deprecated
+Attempting to mutate a string literal now causes a runtime error.
- * test-suite/tests/reader.test: Fix deprecated tests; begin-deprecated
- was splicing in expression context before, which is a no-no.
+** Fix pthread redirection
+
+Guile 2.0.0 shipped with headers that, if configured with pthread
+support, would re-define `pthread_create', `pthread_join', and other API
+to redirect to the BDW-GC wrappers, `GC_pthread_create', etc. This was
+unintended, and not necessary: because threads must enter Guile with
+`scm_with_guile', Guile can handle thread registration itself, without
+needing to make the GC aware of all threads. This oversight has been
+fixed.
+
+** `with-continuation-barrier' now unwinds on `quit'
+
+A throw to `quit' in a continuation barrier will cause Guile to exit.
+Before, it would do so before unwinding to the barrier, which would
+prevent cleanup handlers from running. This has been fixed so that it
+exits only after unwinding.
+
+** `string->pointer' and `pointer->string' have optional encoding arg
+
+This allows users of the FFI to more easily deal in strings with
+particular (non-locale) encodings, like "utf-8". See "Void Pointers and
+Byte Access" in the manual, for more.
-commit cf9d4a82146556ff45d40d6eec8579082287900e
-Author: Ian Price <ianprice90@googlemail.com>
-Date: Wed Apr 6 01:53:38 2011 +0100
+** R6RS fixnum arithmetic optimizations
+
+R6RS fixnum operations are are still slower than generic arithmetic,
+however.
- Added optional second arg to R6RS log function
+** New procedure: `define-inlinable'
- * module/rnrs/base.scm (log): now takes a base argument, using the
- change of base formula for logs.
- * test-suite/tests/r6rs-base.test ("log (2nd arg)"): Add test cases.
+See "Inlinable Procedures" in the manual, for more.

-Author: Ian Price <ianprice90@googlemail.com>
-Date: Wed Apr 6 13:51:44 2011 +0100
+** New procedure: `exact-integer-sqrt'
- fix assert to return true value.
+See "Integer Operations" in the manual, for more.
- * module/rnrs/base.scm (assert): returns value instead of void.
-
- * test-suite/tests/r6rs-base.test ("assert"): add test cases.
+** "Extended read syntax" for symbols parses better
-commit c89b45299329d034875429804f18768c1ea96713
-Author: Ian Price <ianprice90@googlemail.com>
-Date: Fri Apr 8 02:49:20 2011 +0100
+In #{foo}# symbols, backslashes are now treated as escapes, as the
+symbol-printing code intended. Additionally, "\x" within #{foo}# is now
+interpreted as starting an R6RS hex escape. This is backward compatible
+because the symbol printer would never produce a "\x" before. The
+printer also works better too.
- Fix fencepost error in bip_seek
-
- * libguile/r6rs-ports.c (bip_seek): Fix to allow seeking to end of port.
-
- * test-suite/tests/r6rs-ports.test ("bytevector input port can seek to
- very end"): Add tests.
+** Added `--fresh-auto-compile' option

+This allows a user to invalidate the auto-compilation cache. It's
+usually not needed. See "Compilation" in the manual, for a discussion.
- --disable-threads fix
-
- * libguile/threads.c (do_thread_exit_trampoline, on_thread_exit):
- (scm_i_init_thread_for_guile): Only register and unregister threads
- with bdw-gc when we are building with threads support. Thanks to
- Marijn for the report.
+* Manual updates
+** GOOPS documentation updates
+** New man page
+Thanks to Mark Harig for improvements to guile.1.
+** SRFI-23 documented
-* New procedures (see the manual for details)
+The humble `error' SRFI now has an entry in the manual.
-** exact-integer-sqrt, imported into core from (rnrs base)
+* New modules
+** `(ice-9 binary-ports)': "R6RS I/O Ports", in the manual
+** `(ice-9 eval-string)': "Fly Evaluation", in the manual
+** `(ice-9 command-line)', not documented yet
+
* Bugs fixed
-** exact-integer-sqrt now handles large integers correctly
+** Fixed `iconv_t' memory leak on close-port
+** Fixed some leaks with weak hash tables
+** Export `vhash-delq' and `vhash-delv' from `(ice-9 vlist)'
+** `after-gc-hook' works again

+** Quotient, remainder and modulo accept inexact integers again
+** Fix `continue' within `while' to take zero arguments
+** Fix alignment for structures in FFI
+** Fix port-filename of stdin, stdout, stderr to match the docs
+** Fix weak hash table-related bug in `define-wrapped-pointer-type'
+** Fix partial continuation application with pending procedure calls
+** scm_{to,from}_locale_string use current locale, not current ports
+** Fix thread cleanup, by using a pthread_key destructor
+** Fix `quit' at the REPL
+** Fix a failure to sync regs in vm bytevector ops
+** Fix (texinfo reflection) to handle nested structures like syntax patterns
+** Fix stexi->html double translation
+** Fix tree-il->scheme fix for <prompt>
+** Fix compilation of <prompt> in <fix> in single-value context
+** Fix race condition in ensure-writable-dir
+** Fix error message on ,disassemble "non-procedure"
+** Fix prompt and abort with the boot evaluator
+** Fix `procedure->pointer' for functions returning `void'
+** Fix error reporting in dynamic-pointer
+** Fix problems detecting coding: in block comments
+** Fix duplicate load-path and load-compiled-path in compilation environment
+** Add fallback read(2) suppport for .go files if mmap(2) unavailable
+** Fix c32vector-set!, c64vector-set!
+** Fix mistakenly deprecated read syntax for uniform complex vectors
+** Fix parsing of exact numbers with negative exponents
+** Ignore SIGPIPE in (system repl server)
+** Fix optional second arg to R6RS log function
+** Fix R6RS `assert' to return true value.
+** Fix fencepost error when seeking in bytevector input ports
+** Gracefully handle `setlocale' errors when starting the REPL
+** Improve support of the `--disable-posix' configure option
+** Make sure R6RS binary ports pass `binary-port?' regardless of the locale
+** Gracefully handle unterminated UTF-8 sequences instead of hitting an `assert'
-exact-integer-sqrt now works correctly when applied to very large
-integers (too large to be precisely represented by a C double).
-It has also been imported into core from (rnrs base).
