140  the need for a pre-installed "chicken" executable
141- literals are compiled in a platform-independent binary encoding into
142  the executable which results in faster C compile times and moe compact
143  binaries. This also makes the "compress-literals" option and declaration
144  unnecessary
145- the "-compress-literals" compiler option and the "compress-literals"

172  compiling extensions in "host" mode when using a cross-compiling
173  chicken

3022.5
303
304- Bugfixes
305- CHICKEN can now be built using CMake <http://www.cmake.org>, in fact CMake
306  is required to built CHICKEN from sources on Windows with the Microsoft
307  tools
308- the whole build process has been cleaned up and simplified
309- the "easyffi" and "tinyclos" library units have been removed from the base
310  system and are now available as separate extensions
311- the deprecated "set-dispatch-read-syntax!" has been removed

313  ("fx..."/"fp...") with respect to safe/unsafe mode
314- added "(finite? NUMBER)"
315- the "$" macro moved into its own separate extension
316- the values of "software-type", "software-version", "machine-type" and "machine-byte-order"
317  are now registered as features and can be tested using "cond-expand" or "#+"

319- chicken-setup: added "-test" option
320
321Special thanks to Brandon Van Every, who put considerable effort into the
322CHICKEN build system and who ported it to CMake completely from scratch.
323The installation instructions and build file are extensively documented and may
324serve as a tutorial for creating non-trivial software projects with CMake.
325Thanks, Brandon! Also thanks to Bill Hoffmann and Brad King from Kitware
326for their support.

3332.41
334
335- Bugfixes galore
336- compiler:
337  * added support for the generation of "export" files through the "-emit-exports" option
338  * new option `-check-imports' (csc: `-G') checks for unimported symbols and can be quite
339    helpful in finding unbound variable errors (this requires all extensions ("eggs") to be
340    adapted to this new feature, a process which isn't complete yet)
341  * new declarations `emit-exports', `constant' and `import'
342  * new option `-disable-warning' and declaration `disable-warning'
343  * new options `-release' and `-import'
344- chicken-setup:
345  * new `exports' extension property
346  * option `-check' checks for extension upgrades
347  * added `-eval' option
348  * added parameters `setup-install-flag' and `setup-verbose-flag'
349- FFI:
350  * added the handy `$' macro, which lets you do foreign calls directly without declaring
351    a placeholder procedure
352  * `define-foreign-enum' for treating C enums as symbol-sets
353  * `foreign-safe-wrapper' has been deprecated
354- Slight reorganization of TinyCLOS and match macros and support code
355- `thread-join!' has been generalized to allow a thread to have multiple results
356- Renamed `thread-deliver-signal!' to `thread-signal!' and `invalid-procedure-call-handler'
357  to `set-procedure-call-handler!'
358- The system can be configured to add an extra slot to symbol objects
359- Another configuration option enables GC of unused symbols by default
360- The extension repository is now versioned to catch binary incompatible
361  installations, this requires to either move all installed extensions to the
362  new location ("$prefix/lib/chicken/1") or reinstall them
363- Now supports SRFI-61 (extended `cond')
364- Added procedures `load-relative', `tcp-buffer-size`, `string-chomp'
365- trivial implementations of `real-part', `imag-part', `angle' and `magnitude' have
366  been added to the library to allow more portable code
367- Breakpoints and single-stepping of compiled code on the function-level, new
368  procedures `breakpoint' and `singlestep'
369- csi: new toplevel commands `,info', `,step', `,br', `,ubr', `,breakall', `,breakonly',
370  `,exn' and `,c'
371- csi: `set-describer!' allows definition of custom output for the `,d' command
372- Added `integer64' foreign type specifier
373- The environment variable "CHICKEN_PREFIX" allows (together with "CHICKEN_REPOSITORY") overriding
374  the installation path prefix in case you want to install and run multiple instances/versions
375  of CHICKEN or install on a shared network
376- csc: added `-dry-run' option
377- removed `-split...' options (and the ability to generate multiple C files from a single
378  Scheme file)
379- `crictical-section', `disable-interrupts' and `enable-interrupts' shouldn't be used from
380  now on (deprecated), use SRFI-18 mutexes instead
381

400  * options `-home', `-cflags', `-ldflags', `-libs', `-cc-name' and `-ld-name'
401- chicken-setup:
402  * detects whether eggs are gzipped or not and accepts ungzipped eggs
403  * if no other actions are specified and no eggs are given on the command line, then
404    all .setup scripts in the current directory are executed
405  * added `setup-build-directory' and `setup-root-directory' parameters
406  * helper procedures `copy-file', `move-file', `remove-file' and `create-directory'
407- csi commands `,s', `,l' and `,ln' accept multiple inputs, the `trace'/`untrace'
408  macros have been replaced byy the toplevel commands `,tr' and `,utr'
409- new toplevel commands in csi can be defined with the `toplevel-command' procedure
410- `extension-info' has been renamed to `extension-information'. The old name is
411  still available, but deprecated
412- `print-backtrace' has been renamed to `print-call-chain'. The old name is still
413  available (and deprecated)
414- `transcript-on' and `transcript-off' are no longer supported
415- New macro `define-for-syntax'
416- library:

420  (current-gc-milliseconds)
421  `print-error-message' writes now to the current output-port, not the error port
422  `number-string' does now a slightly better job converting large exact integers
423  with non-decimal base
424- extras:
425  (each PROC ...)
426  `hash-table-ref' throws (exn access) on error
427- posix:

435- `set-dispatch-read-syntax!' has been renamed to `set-sharp-read-syntax!' (the old
436  name is still available but deprecated)
437- evaluated code generates call-trace information (as compiled code does), which
438  results in much better back-traces.
439- new foreign types `[unsigned-]int32' and `[unsigned-]integer32'
440- added SRFI-17 setters for many accessors of the core libraries
441- tinyclos: added a couple of missing classes for core library structures
442- `let[*]-values' is now SRFI-11 compliant
443- the finalizer-table is now resized dynamically, which speeds up code that uses
444  very many finalizers [Thanks to Zbigniew Szadkowski]
445- reloading compiled code dynamically does basically work (but still leaks memory)
446- the manual contains a section on pattern matching
447- libffi is used by default, when available
448- CHICKEN has now experimental support for the "CMake" build system <http://www.cmake.org>

4652.2
466
467- Many bugfixes
468- The read-syntax `#+X Y' is provided as a shorthand for `(cond-expand (X Y) (else))'
469- `foreign-parse' and `foreign-parse/spec' have been removed
470- lolevel: Executable byte-vector stuff has been removed
471- SRFIs 28, 31, 62 and 69 are now officially supported
472- New compiler option `-extension' simplifies static compilation of eggs
473- csc: changed `-E' to `-P', `-E' is now an alias for `-extension'
474- Embedding:
475  * All the `entry-point' related things have been removed, as has been `define-embedded',
476    calling Scheme from C is now exclusively done with callbacks
477  * Integrated boilerplate embedding API into the `eval' unit
478  * Added `CHICKEN_continue' API function
479  * Default "stub" toplevel (`CHICKEN_default_toplevel') allows embedding without a
480    separate Scheme file
481  * Different stack-levels during invocation of CHICKEN_run or callbacks could result
482    in crashes - this is now detected (or can be checked manually)
483- Added extension-specifier `(version ...)'
484- New FFI macros `foreign-declare', `foreign-parse' and `foreign-parse/declare' replace
485  the declaration-specifiers of the same name
486- Hash-table resizing was ridiculously slow, and should now be much faster
487- `define-foreign-record' handles recursive structures
488- `require-extension' is now available by default, and so can be used with the
489  plain Scheme evaluator
490- Procedures now contain some basic debug information, unless a file was compiled
491  with `-no-lambda-info'
492- compiler: `-debug-level 2' is now the default (enables trace- and lambda-info)
493- chicken-setup:
494  * handles direct downloads from arbitrary URLs
495  * HTML documentation for eggs can now be included into the egg and will be installed
496    in the repository (using the `documentation' info-property)
497  * `chicken-setup -docindex' shows path of generated documentation index for all
498    installed eggs
499- extras:
500  * SRFI-69 is now fully supported, note that THIS WILL BREAK EXISTING CODE, since
501    the API is not compatible to the previous one
502  * `clear-hash-table!', `get' and `put!' are gone
503  * `read-file' accepts optional reader procedure and max count
504  * `read-lines' accepts filename instead of port
505- library:
506  * `signum' is now exactness-preserving
507  * `procedure-information' returns some basic debug info for a given procedure
508  * Added `(warning MESSAGE ARGUMENTS ...)'
509  * `(promise? X)'
510- posix:
511  * `(current-directory DIR)' is equivalent to `(change-directory DIR)'
512- regex:
513  * `pattern->regexp' has been renamed to `glob->regexp'
514- The `format' library unit has been removed from the base system and is noww available
515  separately
516- SRFI-17, on the other hand has been moved into the base system
517- String literals and the print-names of symbol literals are now allocated in static
518  (non-GC'd) memory
519- If static or shared build is disabled, no `...-static' executables will be generated

5272.0
528
529- Many bugfixes
530- Loads of minor improvements (better error messages, more warnings, more error
531  checks, etc.)
532- On systems supported by the "libffi" library, the 128-argument limit can
533  be exceeded (currently to an arbitrary maximum of 1000). To take advantage
534  of this, add `--with-libffi' to the configuration options when building
535  chicken
536- The `libsrfi-chicken' and `libstuffed-chicken' libraries have been folded
537  into `libchicken', so only a single library is linked with generated
538  executables, which greatly simplifies and speeds up the build process.
539  It is recommended to remove any traced of `libstuffed-chicken.*' and
540  `libsrfi-chicken.*' before installing a new release. This requires also
541  to reinstall all eggs (extension libraries).
542- The compiler is able to inline more procedure calls
543- Implicit non-multival continuations (like in `begin' or 'let') accept multiple
544  values and discard all but the first value
545- finalization should actually work now and is much more efficient (unless
546  used excessively)
547- csi:
548  `advise' has been removed
549  `-eval' implies `-batch' and `-quiet'
550  added `-require-extension'
551  short option names are now supported and may be collapsed, if unambigous
552- New runtime options:
553  -:b (enter REPL on error)
554  -:B (ring bell on every major GC)
555  -:fNNN (set pending finalizer maximum limit)
556- New compiler options:
557  -accumulate-profile
558  -inline
559  -inline-limit
560  -emit-external-prototypes-first
561- The compiler-option `-require-for-syntax' has been renamed to `-require-extension'
562  and is the same as putting a `(require-extension ...)' form directly into the code
563- Removed compiler- and interpreter option `-no-feature'
564- New declarations:
565  (lambda-lift)
566  ([not] inline)
567  (inline-limit LIMIT)
568  (emit-external-prototypes-first)
569  ([not] check-c-syntax)
570- `foreign-callback-lambda[*]' has been renamed to `foreign-safe-lambda[*]' - the
571  old names are still valid but deprecated
572- New foreign type specifier `scheme-pointer' (the same as `pointer', which is
573  deprecated now)
574- Easy FFI:
575  `___scheme_pointer' and `___byte_vector' pseudo types
576  `___pointer' and `___length' markers
577  `default_renaming' and `opaque' pseudo declarations
578  `___inout' and `___out' argument markers work also for C++ reference types
579  Recognizes `C_word' and `size_t'
580- The reader supports selective case sensitive/insensitive reading using the
581  `#cs...' and `#ci...' syntax (as supported in PLT Scheme)
582- `\uXXXX' and `\UXXXXXXXX' escape-sequences for string literals
583- `#\UXXXXXXXX' character literal syntax
584- `\v', `\a' and `\f' escape sequences and `#\delete', `#\esc', `#\alarm', `#\vtab'
585  and `#\nul' character literals
586- `chicken-setup' supports proxy connections via the `-proxy' option
587- library:
588  (set-dynamic-load-mode! MODE)
589  `(end-of-file)' has been removed (use `#!eof' instead)
590- The alternative continuation API described in Marc Feeley's paper
591  "A better API for first class continuations" is supported natively:
592  (continuation-capture PROC)
593  (continuation-graft K THUNK)
594  (continuation-return K VALUE ...)
595  (continuation? X)
596- `foreign-primitive' and `define-extension' macros
597- tinyclos:
598  (instance-of? X)
599  `define-method' specializes on all arguments and allows DSSSL keyword argument lists
600- eval:
601  (set-dispatch-read-syntax! CHAR PROC)
602- extras:
603  (hash-table-update! HT KEY PROC INIT)
604  (hash-table-exists? HT KEY)
605  (hash-table-values HT)
606  (hash-table-keys HT)
607  (alist->hash-table ALIST [TEST SIZE])
608  `hash-table->list' has been renamed to `hash-table->alist
609  `hash-table-for-each' takes the arguments in reversed order (the old order is still
610  valid but deprecated)
611  Hash-tables support now user-defined hash functions
612- posix:
613  (file-link OLD NEW)
614  (symbolic-link? FILENAME)
615  (regular-file? FILENAME)
616  errno/exist
617  `process' and `process-execute' allow passing an environment
618- regex:
619  (regexp-escape STR)
620- tcp:
621  (tcp-listener-fileno LISTENER)
622- utils:
623  (port-for-each FN THUNK)
624  (port-map FN THUNK)
625- On Windows, the batch file `win-install.bat' can be used to install the system
626  into the desired location
627- Building Chicken on Windows with the free development tools from Microsoft (VCToolkit,
628  Platform Core SDK) has been tested and is documented in the file `vctk-install.txt'
629- The `-script-meta' option has been removed
630- The srfi-25 and srfi-37 library units and the test-infrastructure facility have been
631  removed from the core system and is now separately available as an extensions (eggs)
632- The syntax-case macro and module system has been removed and also available as an
633  extension. This implies that all compiler- and interpreter options related to hygienic
634  macros and syntax-case are gone as well.
635- All strictness compiler- and interpreter options (and the `strict-reader' parameter)
636  have been removed
637- the `examples' directory and its contents have been removed from the distribution
638
