+\f
+Changes in 2.0.10 (since 2.0.9):
+
+* Notable changes
+
+** New GDB extension to support Guile
+
+Guile now comes with an extension for GDB 7.8 or later (unreleased at
+the time of writing) that simplifies debugging of C code that uses
+Guile. See "GDB Support" in the manual.
+
+** Improved integration between R6RS and native Guile exceptions
+
+R6RS exception handlers, established using 'with-exception-handler' or
+'guard', are now able to catch native Guile exceptions, which are
+automatically converted into appropriate R6RS condition objects.
+
+** Support for HTTP proxies
+
+Guile's built-in web client now honors the 'http_proxy' environment
+variable, as well as the new 'current-http-proxy' parameter. See
+"Web Client" in the manual for details.
+
+** Lexical syntax improvements
+
+*** Support |...| symbol notation.
+
+Guile's core reader and printer now support the R7RS |...| notation
+for writing symbols with arbitrary characters, as a more portable and
+attractive alternative to Guile's native #{...}# notation. To enable
+this notation by default, put one or both of the following in your
+~/.guile:
+
+ (read-enable 'r7rs-symbols)
+ (print-enable 'r7rs-symbols)
+
+*** Support '#true' and '#false' notation for booleans.
+
+The booleans '#t' and '#f' may now be written as '#true' and '#false'
+for improved readability, per R7RS.
+
+*** Recognize '#\escape' character name.
+
+The escape character '#\esc' may now be written as '#\escape', per R7RS.
+
+*** Accept "\|" in string literals.
+
+The pipe character may now be preceded by a backslash, per R7RS.
+
+** Custom binary input ports now support 'setvbuf'.
+
+Until now, ports returned by 'make-custom-binary-input-port' were always
+full-buffered. Now, their buffering mode can be changed using 'setvbuf'.
+
+** SRFI-4 predicates and length accessors no longer accept arrays.
+
+Given that the SRFI-4 accessors don't work for arrays, the fact that the
+predicates and length accessors returned true for arrays was a bug.
+
+** GUILE_PROGS now supports specifying a minimum required version.
+
+The 'GUILE_PROGS' autoconf macro in guile.m4 now allows an optional
+argument to specify a minimum required Guile version. By default, it
+requires Guile >= 2.0. A micro version can also be specified, e.g.:
+GUILE_PROGS([2.0.10])
+
+** Error reporting improvements
+
+*** Improved run-time error reporting in (ice-9 match).
+
+If no pattern matches in a 'match' form, the datum that failed to match
+is printed along with the location of the failed 'match' invocation.
+
+*** Print the faulty object upon invalid-keyword errors.
+*** Improved error reporting of procedures defined by define-inlinable.
+*** Improved error reporting for misplaced ellipses in macro definitions.
+*** Improved error checking in 'define-public' and 'module-add!'.
+*** Improved error when 'include' form with relative path is not in a file.
+
+** Speed improvements
+
+*** 'scm_c_read' on ISO-8859-1 (e.g. binary) unbuffered ports is faster.
+*** New inline asm for VM fixnum multiply, for faster overflow checking.
+*** New inline asm for VM fixnum operations on ARM and 32-bit x86.
+*** 'positive?' and 'negative?' are now compiled to VM primitives.
+*** Numerical comparisons with more than 2 arguments are compiled to VM code.
+*** Several R6RS bitwise operators have been optimized.
+
+** Miscellaneous
+
+*** Web: 'content-disposition' headers are now supported.
+*** Web: 'uri-encode' hexadecimal percent-encoding is now uppercase.
+*** Size argument to 'make-doubly-weak-hash-table' is now optional.
+*** Timeout for 'unlock-mutex' and SRFI-18 'mutex-unlock!' may now be #f.
+
+** Gnulib update
+
+Guile's copy of Gnulib was updated to v0.1-92-g546ff82. The following
+modules were imported from Gnulib: copysign, fsync, isfinite, link,
+lstat, mkdir, mkstemp, readlink, rename, rmdir, and unistd.
+
+* New interfaces
+
+** Cooperative REPL servers
+
+This new facility supports REPLs that run at specified times within an
+existing thread, for example in programs utilizing an event loop or in
+single-threaded programs. This allows for safe access and mutation of
+a program's data structures from the REPL without concern for thread
+synchronization. See "Cooperative REPL Servers" in the manual for
+details.
+
+** SRFI-43 (Vector Library)
+
+Guile now includes SRFI-43, a comprehensive library of vector operations
+analogous to the SRFI-1 list library. See "SRFI-43" in the manual for
+details.
+
+** SRFI-64 (A Scheme API for test suites)
+
+Guile now includes SRFI-64, a flexible framework for creating test
+suites. The reference implementation of SRFI-64 has also been updated
+to fully support earlier versions of Guile.
+
+** SRFI-111 (Boxes)
+
+See "SRFI-111" in the manual.
+
+** 'define-values'
+
+See "Binding multiple return values" in the manual.
+
+** Custom ellipsis identifiers using 'with-ellipsis' or SRFI-46.
+
+Guile now allows macro definitions to use identifiers other than '...'
+as the ellipsis. This is convenient when writing macros that generate
+macro definitions. The desired ellipsis identifier can be given as the
+first operand to 'syntax-rules', as specified in SRFI-46 and R7RS, or by
+using the new 'with-ellipsis' special form in procedural macros. With
+this addition, Guile now fully supports SRFI-46.
+
+See "Specifying a Custom Ellipsis Identifier" and "Custom Ellipsis
+Identifiers for syntax-case Macros" in the manual for details.
+
+** R7RS 'syntax-error'
+
+Guile now supports 'syntax-error', as specified by R7RS, allowing for
+improved compile-time error reporting from 'syntax-rules' macros. See
+"Reporting Syntax Errors in Macros" in the manual for details.
+
+** New procedures to convert association lists into hash tables
+
+Guile now includes the convenience procedures 'alist->hash-table',
+'alist->hashq-table', 'alist->hashv-table', and 'alist->hashx-table'.
+See "Hash Table Reference" in the manual.
+
+** New predicates: 'exact-integer?' and 'scm_is_exact_integer'
+
+See "Integers" in the manual.
+
+** 'weak-vector-length', 'weak-vector-ref', and 'weak-vector-set!'
+
+These should now be used to access weak vectors, instead of
+'vector-length', 'vector-ref', and 'vector-set!'.
+
+* Manual updates
+
+** Improve docs for 'eval-when'.
+
+Each 'eval-when' condition is now explained in detail, including
+'expand' which was previously undocumented. (expand load eval) is now
+the recommended set of conditions, instead of (compile load eval).
+See "Eval When" in the manual, for details.
+
+** Update the section on SMOBs and memory management.
+
+See "Defining New Types (Smobs)" in the manual.
+
+** Fixes
+
+*** GOOPS: #:dsupers is the init keyword for the dsupers slot.
+*** 'unfold-right' takes a tail, not a tail generator.
+*** Clarify that 'append!' and 'reverse!' might not mutate.
+*** Fix doc that incorrectly claimed (integer? +inf.0) => #t.
+ (http://bugs.gnu.org/16356)
+*** Document that we support SRFI-62 (S-expression comments).
+*** Document that we support SRFI-87 (=> in case clauses).
+*** Document 'equal?' in the list of R6RS incompatibilities.
+*** Remove outdated documentation of LTDL_LIBRARY_PATH.
+*** Fix 'weak-vector?' doc: Weak hash tables are not weak vectors.
+*** Fix 'my-or' examples to use let-bound variable.
+ (http://bugs.gnu.org/14203)
+
+* New deprecations
+
+** General 'uniform-vector' interface
+
+This interface lacked both generality and specificity. The general
+replacements are 'array-length', 'array-ref', and friends on the scheme
+side, and the array handle interface on the C side. On the specific
+side of things, there are the specific bytevector, SRFI-4, and bitvector
+interfaces.
+
+** Use of the vector interface on arrays
+** 'vector-length', 'vector-ref', and 'vector-set!' on weak vectors
+** 'vector-length', 'vector-ref', and 'vector-set!' as primitive-generics
+
+Making the vector interface operate only on a single representation will
+allow future versions of Guile to compile loops involving vectors to
+more efficient native code.
+
+** 'htons', 'htonl', 'ntohs', 'ntohl'
+
+These procedures, like their C counterpart, were used to convert numbers
+to/from network byte order, typically in conjunction with the
+now-deprecated uniform vector API.
+
+This functionality is now covered by the bytevector and binary I/O APIs.
+See "Interpreting Bytevector Contents as Integers" in the manual.
+
+** 'gc-live-object-stats'
+
+It hasn't worked in the whole 2.0 series. There is no replacement,
+unfortunately.
+
+** 'scm_c_program_source'
+
+This internal VM function was not meant to be public. Use
+'scm_procedure_source' instead.
+
+* Build fixes
+
+** Fix build with Clang 3.4.
+
+** MinGW build fixes
+*** Do not add $(EXEEXT) to guild or guile-tools.
+*** tests: Use double quotes around shell arguments, for Windows.
+*** tests: Don't rely on $TMPDIR and /tmp on Windows.
+*** tests: Skip FFI tests that use `qsort' when it's not accessible.
+*** tests: Remove symlink only when it exists.
+*** tests: Don't rely on `scm_call_2' being visible.
+
+** Fix computation of LIBLOBJS so dependencies work properly.

+Changes in 2.0.9 (since 2.0.7):
---language docs
+Note: 2.0.8 was a brown paper bag release that was never announced, but
+some mirrors may have picked it up. Please do not use it.
* Notable changes
-** New guile.m4.
+** New keyword arguments for procedures that open files
+
+The following procedures that open files now support keyword arguments
+to request binary I/O or to specify the character encoding for text
+files: `open-file', `open-input-file', `open-output-file',
+`call-with-input-file', `call-with-output-file', `with-input-from-file',
+`with-output-to-file', and `with-error-to-file'.
+
+It is also now possible to specify whether Guile should scan files for
+Emacs-style coding declarations. This scan was done by default in
+versions 2.0.0 through 2.0.7, but now must be explicitly requested.
+
+See "File Ports" in the manual for details.
+
+** Rewritten guile.m4
The `guile.m4' autoconf macros have been rewritten to use `guild' and
`pkg-config' instead of the deprecated `guile-config' (which itself
the version of Guile that they want to compile against. See "Autoconf
Macros" in the manual, for more information.
-** Better Windows support.
+** Better Windows support
Guile now correctly identifies absolute paths on Windows (MinGW), and
creates files on that platform according to its path conventions. See
-XXX in the manual, for all details.
+"File System" in the manual, for all details.
In addition, the new Gnulib imports provide `select' and `poll' on
Windows builds.
As an incompatible change, systems that are missing <sys/select.h> were
previously provided a public `scm_std_select' C function that defined a
version of `select', but unhappily it also provided its own incompatible
-definitions for FD_SET, FD_ZERO, and other system interface. Guile
+definitions for FD_SET, FD_ZERO, and other system interfaces. Guile
should not be setting these macros in public API, so this interface was
removed on those plaforms (basically only MinGW).
-** Gnulib update.
+** Numerics improvements
-Guile's copy of Gnulib was updated to v0.0-7865-ga828bb2. The following
-modules were imported from Gnulib: select, times, pipe-posix, fstat,
-getlogin, and poll.
+`number->string' now reliably outputs enough digits to produce the same
+number when read back in. Previously, it mishandled subnormal numbers
+(printing them as "#.#"), and failed to distinguish between some
+distinct inexact numbers, e.g. 1.0 and (+ 1.0 (expt 2.0 -52)). These
+problems had far-reaching implications, since the compiler uses
+`number->string' to serialize numeric constants into .go files.
+
+`sqrt' now produces exact rational results when possible, and handles
+very large or very small numbers more robustly.
+
+A number (ahem) of operations involving exact rationals have been
+optimized, most notably `integer-expt' and `expt'.
-** New optimizations.
+`exact->inexact' now performs correct IEEE rounding.
+
+** New optimizations
There were a number of improvements to the partial evaluator, allowing
complete reduction of forms such as:
((lambda _ _))
- (apply (lambda _) 1 2 3 4)
+ (apply (lambda _ _) 1 2 3 '(4))
(call-with-values (lambda () (values 1 2)) (lambda _ _))
-A number (ahem) of numeric operations on have been made faster, among
-them GCD and logarithms.
+`string-join' now handles huge lists efficiently.
+
+`get-bytevector-some' now uses buffered input, which is much faster.
+
+Finally, `array-ref', `array-set!' on arrays of rank 1 or 2 is now
+faster, because it avoids building a rest list. Similarly, the
+one-argument case of `array-for-each' and `array-map!' has been
+optimized, and `array-copy!' and `array-fill!' are faster.
-Finally, `array-ref' and `array-set!' on arrays of rank 1 or 2 is now
-faster, because it avoids building a rest list.
+** `peek-char' no longer consumes EOF
-** `include' resolves relative file names relative to including file.
+As required by the R5RS, if `peek-char' returns EOF, then the next read
+will also return EOF. Previously `peek-char' would consume the EOF.
+This makes a difference for terminal devices where it is possible to
+read past an EOF.
+
+** Gnulib update
+
+Guile's copy of Gnulib was updated to v0.0-7865-ga828bb2. The following
+modules were imported from Gnulib: select, times, pipe-posix, fstat,
+getlogin, poll, and c-strcase.
+
+** `include' resolves relative file names relative to including file
Given a relative file name, `include' will look for it relative to the
directory of the including file. This harmonizes the behavior of
`include' with that of `load'.
-** SLIB compatibility restored.
+** SLIB compatibility restored
Guile 2.0.8 is now compatible with SLIB. You will have to use a
development version of SLIB, however, until a new version of SLIB is
released.
-** Better ,trace REPL command.
+** Better ,trace REPL command
Sometimes the ,trace output for nested function calls could overflow the
terminal width, which wasn't useful. Now there is a limit to the amount
of space the prefix will take. See the documentation for ",trace" for
more information.
-** Update predefined character sets to Unicode 6.2.
+** Better docstring syntax supported for `case-lambda'
+
+Docstrings can now be placed immediately after the `case-lambda' or
+`case-lambda*' keyword. See "Case-lambda" in the manual.
+
+** Improved handling of Unicode byte order marks
+
+See "BOM Handling" in the manual for details.
+
+** Update predefined character sets to Unicode 6.2
+
+** GMP 4.2 or later required
+
+Guile used to require GMP at least version 4.1 (released in May 2002),
+and now requires at least version 4.2 (released in March 2006).
* Manual updates
-** Better SXML documentation.
+** Better SXML documentation
The documentation for SXML modules was much improved, though there is
still far to go. See "SXML" in manual.
-** Style updates.
+** Style updates
Use of "iff" was replaced with standard English. Keyword arguments are
now documented consistently, along with their default values.
-** An end to the generated-documentation experiment.
+** An end to the generated-documentation experiment
When Guile 2.0 imported some modules from Guile-Lib, they came with a
system that generated documentation from docstrings and module
improving them manually over time, as is the case with SXML. Help is
appreciated.
-** New documentation.
+** New documentation
There is now documentation for `scm_array_type', and `scm_array_ref', as
well as for the new `array-length' / 'scm_c_array_length' /
`scm_array_length' functions. `array-in-bounds?' has better
documentation as well. The `program-arguments-alist' and
-`program-lambda-list' functions are now documented. Finally, the GOOPS
-class hierarchy diagram has been regenerated for the web and print
-output formats.
+`program-lambda-list' functions are now documented, as well as `and=>',
+`exit', and `quit'. The (system repl server) module is now documented
+(see REPL Servers). Finally, the GOOPS class hierarchy diagram has been
+regenerated for the web and print output formats.
* New deprecations
-** Deprecate generalized vector interface.
+** Deprecate generalized vector interface
The generalized vector interface, introduced in 1.8.0, is simply a
redundant, verbose interface to arrays of rank 1. `array-ref' and
`scm_generalized_vector_ref', `scm_generalized_vector_set_x', and
`scm_generalized_vector_to_list' are now deprecated.
-** Deprecate SCM_CHAR_CODE_LIMIT and char-code-limit.
+** Deprecate SCM_CHAR_CODE_LIMIT and char-code-limit
These constants were defined to 256, which is not the highest codepoint
supported by Guile. Given that they were useless and incorrect, they
have been deprecated.
-** Deprecate `http-get*'.
+** Deprecate `http-get*'
The new `#:streaming?' argument to `http-get' subsumes the functionality
of `http-get*' (introduced in 2.0.7). Also, the `#:extra-headers'
argument is deprecated in favor of `#:headers'.
-** Deprecate (ice-9 mapping).
+** Deprecate (ice-9 mapping)
This module, present in Guile since 1996 but never used or documented,
has never worked in Guile 2.0. It has now been deprecated and will be
removed in Guile 2.2.
+** Deprecate undocumented array-related C functions
+
+These are `scm_array_fill_int', `scm_ra_eqp', `scm_ra_lessp',
+`scm_ra_leqp', `scm_ra_grp', `scm_ra_greqp', `scm_ra_sum',
+`scm_ra_product', `scm_ra_difference', `scm_ra_divide', and
+`scm_array_identity'.
+
* New interfaces
-** `round-ash', a bit-shifting operator that rounds on right-shift.
+** SRFI-41 Streams
-See "Bitwise Operations".
+See "SRFI-41" in the manual.
-** New environment variables: `GUILE_STACK_SIZE', `GUILE_INSTALL_LOCALE'.
+** SRFI-45 exports `promise?'
-See "Environment Variables".
+SRFI-45 now exports a `promise?' procedure that works with its promises.
+Also, its promises now print more nicely.
+
+** New HTTP client procedures
+
+See "Web Client" for documentation on the new `http-head', `http-post',
+`http-put', `http-delete', `http-trace', and `http-options' procedures,
+and also for more options to `http-get'.
-** New procedure `sendfile'.
+** Much more capable `xml->sxml'
+
+See "Reading and Writing XML" for information on how the `xml->sxml'
+parser deals with namespaces, processed entities, doctypes, and literal
+strings. Incidentally, `current-ssax-error-port' is now a parameter
+object.
+
+** New procedures for converting strings to and from bytevectors
+
+See "Representing Strings as Bytes" for documention on the new `(ice-9
+iconv)' module and its `bytevector->string' and `string->bytevector'
+procedures.
+
+** Escape continuations with `call/ec' and `let/ec'
+
+See "Prompt Primitives".
+
+** New procedures to read all characters from a port
+
+See "Line/Delimited" in the manual for documentation on `read-string'
+ and `read-string!'.
+
+** New procedure `sendfile'
See "File System".
-** New procedures for dealing with file names.
+** New procedure `unget-bytevector'
+
+See "R6RS Binary Input".
+
+** New C helper: `scm_c_bind_keyword_arguments'
-See XXX for documentation on `system-file-name-convention',
+See "Keyword Procedures".
+
