129  the need for a pre-installed "chicken" executable
130- literals are compiled in a platform-independent binary encoding into
131  the executable which results in faster C compile times and moe compact

159  SVN checkout of egg repository
160- chicken-setup has the new option "-host-extension" to force
161  compiling extensions in "host" mode when using a cross-compiling
162  chicken
163- Better cross-development support for the build system (the
164  Makefile accepts various variables for customizing the build)

281Tony Sideaway, Minh Thu for reporting bugs, suggesting improvements
282and contributing fixes.
284Thanks again to Brandon Van Every for his extensive work on the CMake
285build process.
287Special thanks to Kon Lovett for many improvements made in the posix
293- Bugfixes
294- CHICKEN can now be built using CMake <>, in fact CMake
295  is required to built CHICKEN from sources on Windows with the Microsoft
296  tools
297- the whole build process has been cleaned up and simplified
298- the "easyffi" and "tinyclos" library units have been removed from the base
299  system and are now available as separate extensions
300- the deprecated "set-dispatch-read-syntax!" has been removed
301- Will Farr cleaned up the behaviour of number-type specific numeric operations
302  ("fx..."/"fp...") with respect to safe/unsafe mode
303- added "(finite? NUMBER)"
304- the "$" macro moved into its own separate extension
305- the values of "software-type", "software-version", "machine-type" and "machine-byte-order"
306  are now registered as features and can be tested using "cond-expand" or "#+"
307- all tools now support the "-release" option
308- chicken-setup: added "-test" option
310Special thanks to Brandon Van Every, who put considerable effort into the
311CHICKEN build system and who ported it to CMake completely from scratch.
312The installation instructions and build file are extensively documented and may
313serve as a tutorial for creating non-trivial software projects with CMake.
314Thanks, Brandon! Also thanks to Bill Hoffmann and Brad King from Kitware
315for their support.
317Many thanks to Peter Bex, Toby Butzon, Thomans Chust, John Cowan, Alejandro Forero Cuervo,
318dgym, Alex Drummond, Mario Domenech Goulart, Kon Lovett, Benedikt Rosenau and Zbigniew
319Szadkowski for reporting bugs, suggesting improvements and contributing fixes.
324- Bugfixes galore
325- compiler:
326  * added support for the generation of "export" files through the "-emit-exports" option
327  * new option `-check-imports' (csc: `-G') checks for unimported symbols and can be quite
328    helpful in finding unbound variable errors (this requires all extensions ("eggs") to be
329    adapted to this new feature, a process which isn't complete yet)
330  * new declarations `emit-exports', `constant' and `import'
331  * new option `-disable-warning' and declaration `disable-warning'
332  * new options `-release' and `-import'
333- chicken-setup:
334  * new `exports' extension property
335  * option `-check' checks for extension upgrades
336  * added `-eval' option
337  * added parameters `setup-install-flag' and `setup-verbose-flag'

339  * added the handy `$' macro, which lets you do foreign calls directly without declaring
340    a placeholder procedure
341  * `define-foreign-enum' for treating C enums as symbol-sets
342  * `foreign-safe-wrapper' has been deprecated
343- Slight reorganization of TinyCLOS and match macros and support code
344- `thread-join!' has been generalized to allow a thread to have multiple results
345- Renamed `thread-deliver-signal!' to `thread-signal!' and `invalid-procedure-call-handler'
346  to `set-procedure-call-handler!'
347- The system can be configured to add an extra slot to symbol objects
348- Another configuration option enables GC of unused symbols by default
349- The extension repository is now versioned to catch binary incompatible
350  installations, this requires to either move all installed extensions to the
351  new location ("$prefix/lib/chicken/1") or reinstall them
352- Now supports SRFI-61 (extended `cond')
353- Added procedures `load-relative', `tcp-buffer-size`, `string-chomp'
354- trivial implementations of `real-part', `imag-part', `angle' and `magnitude' have
355  been added to the library to allow more portable code
356- Breakpoints and single-stepping of compiled code on the function-level, new
357  procedures `breakpoint' and `singlestep'
358- csi: new toplevel commands `,info', `,step', `,br', `,ubr', `,breakall', `,breakonly',
359  `,exn' and `,c'
360- csi: `set-describer!' allows definition of custom output for the `,d' command
361- Added `integer64' foreign type specifier
362- The environment variable "CHICKEN_PREFIX" allows (together with "CHICKEN_REPOSITORY") overriding
363  the installation path prefix in case you want to install and run multiple instances/versions
364  of CHICKEN or install on a shared network
365- csc: added `-dry-run' option
366- removed `-split...' options (and the ability to generate multiple C files from a single
367  Scheme file)
368- `crictical-section', `disable-interrupts' and `enable-interrupts' shouldn't be used from
369  now on (deprecated), use SRFI-18 mutexes instead
371Many thanks to Nico Amtsberg, Arto Bendiken, Jean-Francois Bignolles, Peter Busser, Thomas Chust,
372John Cowan, Alejandro Forero Cuervo, Jaarod Eells, Brandon van Every, Graham Fawcett, Mario Domenech

380- Many many bugfixes
381- compiler:
382  * new option `-profile-name FILENAME'
383- the `chicken-config' script has been removed, identical functionality can be provided
384  by `csc'
385- csc:
386  * new option `-objc' compiles generated C files in Objective-C mode
387  * accepts .m files and handles the case when only object files are given

389  * options `-home', `-cflags', `-ldflags', `-libs', `-cc-name' and `-ld-name'
390- chicken-setup:
391  * detects whether eggs are gzipped or not and accepts ungzipped eggs
392  * if no other actions are specified and no eggs are given on the command line, then
393    all .setup scripts in the current directory are executed
394  * added `setup-build-directory' and `setup-root-directory' parameters
395  * helper procedures `copy-file', `move-file', `remove-file' and `create-directory'
396- csi commands `,s', `,l' and `,ln' accept multiple inputs, the `trace'/`untrace'
397  macros have been replaced byy the toplevel commands `,tr' and `,utr'
398- new toplevel commands in csi can be defined with the `toplevel-command' procedure
399- `extension-info' has been renamed to `extension-information'. The old name is
400  still available, but deprecated
401- `print-backtrace' has been renamed to `print-call-chain'. The old name is still
402  available (and deprecated)
403- `transcript-on' and `transcript-off' are no longer supported
404- New macro `define-for-syntax'
405- library:
406  (get-call-chain [DEPTH])
407  (current-read-table)
408  (copy-read-table READ-TABLE)
409  (current-gc-milliseconds)
410  `print-error-message' writes now to the current output-port, not the error port
411  `number-string' does now a slightly better job converting large exact integers
412  with non-decimal base
413- extras:
414  (each PROC ...)
415  `hash-table-ref' throws (exn access) on error
416- posix:
417  (local-time->seconds TIME)
418  (utc-time->seconds TIME)
419  (local-timezone-abbreviation)
420  `directory' takes optional path and dotfiles arguments
421  `[group|system]-information' return lists instead of multiple values
422- tcp:
423  (tcp-port-numbers PORT)
424- `set-dispatch-read-syntax!' has been renamed to `set-sharp-read-syntax!' (the old
425  name is still available but deprecated)
426- evaluated code generates call-trace information (as compiled code does), which
427  results in much better back-traces.
428- new foreign types `[unsigned-]int32' and `[unsigned-]integer32'
429- added SRFI-17 setters for many accessors of the core libraries
430- tinyclos: added a couple of missing classes for core library structures
431- `let[*]-values' is now SRFI-11 compliant
432- the finalizer-table is now resized dynamically, which speeds up code that uses
433  very many finalizers [Thanks to Zbigniew Szadkowski]
434- reloading compiled code dynamically does basically work (but still leaks memory)
435- the manual contains a section on pattern matching
436- libffi is used by default, when available
437- CHICKEN has now experimental support for the "CMake" build system <>
438  Many thanks to Bill Hoffmann from Kitware and Brandon van Every for helping with this
439- added compiler/runtime support for object serialization via the `s11n' extension
440  (see <>)

443Thanks, Sergey!
445Many thanks Jean-Francois Bignolles, Patrick Brannan, Adam Buchbinder, Hans Bulfone, Category 5,
446John Cowan, datrus, Guillaume Germaine, Mario Domenech Goulart, Daniel B. Faken, Andrey Fomichev,
447Jarod Eells, Sven Hartrumpf, David Janssens, Daishi Kato, Levi Pearson, Pupeno, Eric Raible, Benedikt
448Rosenau, Reed Sheridan, Zbigniew Szadkowski and Mark Wutka for their helpful contributions,
449suggestions and bug reports!
451Special thanks to Kon Lovett for fixing countless open issues and many useful sugestions.
456- Many bugfixes

458- `foreign-parse' and `foreign-parse/spec' have been removed
459- lolevel: Executable byte-vector stuff has been removed
460- SRFIs 28, 31, 62 and 69 are now officially supported
461- New compiler option `-extension' simplifies static compilation of eggs
462- csc: changed `-E' to `-P', `-E' is now an alias for `-extension'
463- Embedding:
464  * All the `entry-point' related things have been removed, as has been `define-embedded',
465    calling Scheme from C is now exclusively done with callbacks
466  * Integrated boilerplate embedding API into the `eval' unit
467  * Added `CHICKEN_continue' API function
468  * Default "stub" toplevel (`CHICKEN_default_toplevel') allows embedding without a
469    separate Scheme file
470  * Different stack-levels during invocation of CHICKEN_run or callbacks could result
471    in crashes - this is now detected (or can be checked manually)
472- Added extension-specifier `(version ...)'
473- New FFI macros `foreign-declare', `foreign-parse' and `foreign-parse/declare' replace
474  the declaration-specifiers of the same name
475- Hash-table resizing was ridiculously slow, and should now be much faster
476- `define-foreign-record' handles recursive structures
477- `require-extension' is now available by default, and so can be used with the
478  plain Scheme evaluator
479- Procedures now contain some basic debug information, unless a file was compiled
480  with `-no-lambda-info'
481- compiler: `-debug-level 2' is now the default (enables trace- and lambda-info)
482- chicken-setup:
483  * handles direct downloads from arbitrary URLs
484  * HTML documentation for eggs can now be included into the egg and will be installed
485    in the repository (using the `documentation' info-property)
486  * `chicken-setup -docindex' shows path of generated documentation index for all
487    installed eggs
488- extras:
489  * SRFI-69 is now fully supported, note that THIS WILL BREAK EXISTING CODE, since
490    the API is not compatible to the previous one
491  * `clear-hash-table!', `get' and `put!' are gone
492  * `read-file' accepts optional reader procedure and max count
493  * `read-lines' accepts filename instead of port
494- library:
495  * `signum' is now exactness-preserving
496  * `procedure-information' returns some basic debug info for a given procedure
497  * Added `(warning MESSAGE ARGUMENTS ...)'
498  * `(promise? X)'
499- posix:
500  * `(current-directory DIR)' is equivalent to `(change-directory DIR)'
501- regex:
502  * `pattern->regexp' has been renamed to `glob->regexp'
503- The `format' library unit has been removed from the base system and is noww available
504  separately
505- SRFI-17, on the other hand has been moved into the base system
506- String literals and the print-names of symbol literals are now allocated in static
507  (non-GC'd) memory
508- If static or shared build is disabled, no `...-static' executables will be generated
511Many thanks to Ashley Bone, Thomas Chust, John Cowan, Alejandro Forero Cuervo, Daniel Faken, Sven
512Hartrumpf, Daishi Kato, Sergey Khorev, Kon Lovett, Gene Pavlovsky, Reed Sheridan and Ed Watkeys for
513their helpful contributions, suggestions and bug reports!
518- Many bugfixes
519- Loads of minor improvements (better error messages, more warnings, more error
520  checks, etc.)
521- On systems supported by the "libffi" library, the 128-argument limit can
522  be exceeded (currently to an arbitrary maximum of 1000). To take advantage
523  of this, add `--with-libffi' to the configuration options when building
524  chicken
525- The `libsrfi-chicken' and `libstuffed-chicken' libraries have been folded
526  into `libchicken', so only a single library is linked with generated
527  executables, which greatly simplifies and speeds up the build process.
528  It is recommended to remove any traced of `libstuffed-chicken.*' and
529  `libsrfi-chicken.*' before installing a new release. This requires also
530  to reinstall all eggs (extension libraries).
531- The compiler is able to inline more procedure calls
532- Implicit non-multival continuations (like in `begin' or 'let') accept multiple
533  values and discard all but the first value
534- finalization should actually work now and is much more efficient (unless
535  used excessively)
536- csi:
537  `advise' has been removed
538  `-eval' implies `-batch' and `-quiet'
539  added `-require-extension'
540  short option names are now supported and may be collapsed, if unambigous
541- New runtime options:
542  -:b (enter REPL on error)
543  -:B (ring bell on every major GC)
544  -:fNNN (set pending finalizer maximum limit)
545- New compiler options:
546  -accumulate-profile
547  -inline
548  -inline-limit
549  -emit-external-prototypes-first
550- The compiler-option `-require-for-syntax' has been renamed to `-require-extension'
551  and is the same as putting a `(require-extension ...)' form directly into the code
552- Removed compiler- and interpreter option `-no-feature'
553- New declarations:
554  (lambda-lift)
555  ([not] inline)
556  (inline-limit LIMIT)
557  (emit-external-prototypes-first)
558  ([not] check-c-syntax)
559- `foreign-callback-lambda[*]' has been renamed to `foreign-safe-lambda[*]' - the
560  old names are still valid but deprecated
561- New foreign type specifier `scheme-pointer' (the same as `pointer', which is
562  deprecated now)
563- Easy FFI:
564  `___scheme_pointer' and `___byte_vector' pseudo types
565  `___pointer' and `___length' markers
566  `default_renaming' and `opaque' pseudo declarations
567  `___inout' and `___out' argument markers work also for C++ reference types
568  Recognizes `C_word' and `size_t'
569- The reader supports selective case sensitive/insensitive reading using the
570  `#cs...' and `#ci...' syntax (as supported in PLT Scheme)
571- `\uXXXX' and `\UXXXXXXXX' escape-sequences for string literals
572- `#\UXXXXXXXX' character literal syntax
573- `\v', `\a' and `\f' escape sequences and `#\delete', `#\esc', `#\alarm', `#\vtab'
574  and `#\nul' character literals
575- `chicken-setup' supports proxy connections via the `-proxy' option
576- library:
577  (set-dynamic-load-mode! MODE)
578  `(end-of-file)' has been removed (use `#!eof' instead)
579- The alternative continuation API described in Marc Feeley's paper
580  "A better API for first class continuations" is supported natively:
581  (continuation-capture PROC)
582  (continuation-graft K THUNK)
583  (continuation-return K VALUE ...)
584  (continuation? X)
585- `foreign-primitive' and `define-extension' macros
586- tinyclos:
587  (instance-of? X)
588  `define-method' specializes on all arguments and allows DSSSL keyword argument lists
589- eval:
590  (set-dispatch-read-syntax! CHAR PROC)
591- extras:
592  (hash-table-update! HT KEY PROC INIT)
593  (hash-table-exists? HT KEY)
594  (hash-table-values HT)
595  (hash-table-keys HT)
596  (alist->hash-table ALIST [TEST SIZE])
597  `hash-table->list' has been renamed to `hash-table->alist
598  `hash-table-for-each' takes the arguments in reversed order (the old order is still
599  valid but deprecated)
600  Hash-tables support now user-defined hash functions
601- posix:
602  (file-link OLD NEW)
603  (symbolic-link? FILENAME)
604  (regular-file? FILENAME)
605  errno/exist
606  `process' and `process-execute' allow passing an environment
607- regex:
608  (regexp-escape STR)
609- tcp:
610  (tcp-listener-fileno LISTENER)
611- utils:
612  (port-for-each FN THUNK)
613  (port-map FN THUNK)
614- On Windows, the batch file `win-install.bat' can be used to install the system
615  into the desired location
616- Building Chicken on Windows with the free development tools from Microsoft (VCToolkit,
617  Platform Core SDK) has been tested and is documented in the file `vctk-install.txt'
618- The `-script-meta' option has been removed
619- The srfi-25 and srfi-37 library units and the test-infrastructure facility have been
620  removed from the core system and is now separately available as an extensions (eggs)
621- The syntax-case macro and module system has been removed and also available as an
622  extension. This implies that all compiler- and interpreter options related to hygienic
623  macros and syntax-case are gone as well.
624- All strictness compiler- and interpreter options (and the `strict-reader' parameter)
625  have been removed
626- the `examples' directory and its contents have been removed from the distribution
