138  compiling extensions in "host" mode when using a cross-compiling
139  chicken

262build process.
264Special thanks to Kon Lovett for many improvements made in the posix
270- Bugfixes
271- CHICKEN can now be built using CMake <>, in fact CMake
272  is required to built CHICKEN from sources on Windows with the Microsoft
273  tools
274- the whole build process has been cleaned up and simplified
275- the "easyffi" and "tinyclos" library units have been removed from the base
276  system and are now available as separate extensions
277- the deprecated "set-dispatch-read-syntax!" has been removed
278- Will Farr cleaned up the behaviour of number-type specific numeric operations
279  ("fx..."/"fp...") with respect to safe/unsafe mode
280- added "(finite? NUMBER)"
281- the "$" macro moved into its own separate extension
282- the values of "software-type", "software-version", "machine-type" and "machine-byte-order"

285- chicken-setup: added "-test" option
287Special thanks to Brandon Van Every, who put considerable effort into the
288CHICKEN build system and who ported it to CMake completely from scratch.
289The installation instructions and build file are extensively documented and may
290serve as a tutorial for creating non-trivial software projects with CMake.
291Thanks, Brandon! Also thanks to Bill Hoffmann and Brad King from Kitware
292for their support.
294Many thanks to Peter Bex, Toby Butzon, Thomans Chust, John Cowan, Alejandro Forero Cuervo,

301- Bugfixes galore
302- compiler:
303  * added support for the generation of "export" files through the "-emit-exports" option
304  * new option `-check-imports' (csc: `-G') checks for unimported symbols and can be quite
305    helpful in finding unbound variable errors (this requires all extensions ("eggs") to be
306    adapted to this new feature, a process which isn't complete yet)
307  * new declarations `emit-exports', `constant' and `import'
308  * new option `-disable-warning' and declaration `disable-warning'
309  * new options `-release' and `-import'
310- chicken-setup:
311  * new `exports' extension property
312  * option `-check' checks for extension upgrades
313  * added `-eval' option
314  * added parameters `setup-install-flag' and `setup-verbose-flag'

319  * `foreign-safe-wrapper' has been deprecated
320- Slight reorganization of TinyCLOS and match macros and support code

323  to `set-procedure-call-handler!'
324- The system can be configured to add an extra slot to symbol objects
325- Another configuration option enables GC of unused symbols by default
326- The extension repository is now versioned to catch binary incompatible
327  installations, this requires to either move all installed extensions to the
328  new location ("$prefix/lib/chicken/1") or reinstall them
329- Now supports SRFI-61 (extended `cond')
330- Added procedures `load-relative', `tcp-buffer-size`, `string-chomp'
331- trivial implementations of `real-part', `imag-part', `angle' and `magnitude' have
332  been added to the library to allow more portable code
333- Breakpoints and single-stepping of compiled code on the function-level, new
334  procedures `breakpoint' and `singlestep'
335- csi: new toplevel commands `,info', `,step', `,br', `,ubr', `,breakall', `,breakonly',
336  `,exn' and `,c'
337- csi: `set-describer!' allows definition of custom output for the `,d' command
338- Added `integer64' foreign type specifier
339- The environment variable "CHICKEN_PREFIX" allows (together with "CHICKEN_REPOSITORY") overriding
340  the installation path prefix in case you want to install and run multiple instances/versions
341  of CHICKEN or install on a shared network
342- csc: added `-dry-run' option
343- removed `-split...' options (and the ability to generate multiple C files from a single
344  Scheme file)
345- `crictical-section', `disable-interrupts' and `enable-interrupts' shouldn't be used from
346  now on (deprecated), use SRFI-18 mutexes instead
348Many thanks to Nico Amtsberg, Arto Bendiken, Jean-Francois Bignolles, Peter Busser, Thomas Chust,

360- the `chicken-config' script has been removed, identical functionality can be provided
361  by `csc'

366  * options `-home', `-cflags', `-ldflags', `-libs', `-cc-name' and `-ld-name'
367- chicken-setup:
368  * detects whether eggs are gzipped or not and accepts ungzipped eggs
369  * if no other actions are specified and no eggs are given on the command line, then
370    all .setup scripts in the current directory are executed
371  * added `setup-build-directory' and `setup-root-directory' parameters
372  * helper procedures `copy-file', `move-file', `remove-file' and `create-directory'
373- csi commands `,s', `,l' and `,ln' accept multiple inputs, the `trace'/`untrace'
374  macros have been replaced byy the toplevel commands `,tr' and `,utr'
375- new toplevel commands in csi can be defined with the `toplevel-command' procedure
376- `extension-info' has been renamed to `extension-information'. The old name is
377  still available, but deprecated
378- `print-backtrace' has been renamed to `print-call-chain'. The old name is still
379  available (and deprecated)
380- `transcript-on' and `transcript-off' are no longer supported
381- New macro `define-for-syntax'
382- library:
383  (get-call-chain [DEPTH])
384  (current-read-table)
385  (copy-read-table READ-TABLE)
386  (current-gc-milliseconds)
387  `print-error-message' writes now to the current output-port, not the error port
388  `number-string' does now a slightly better job converting large exact integers
389  with non-decimal base
390- extras:
391  (each PROC ...)
392  `hash-table-ref' throws (exn access) on error
393- posix:
394  (local-time->seconds TIME)
395  (utc-time->seconds TIME)
396  (local-timezone-abbreviation)
397  `directory' takes optional path and dotfiles arguments

401- `set-dispatch-read-syntax!' has been renamed to `set-sharp-read-syntax!' (the old
402  name is still available but deprecated)
403- evaluated code generates call-trace information (as compiled code does), which
404  results in much better back-traces.
405- new foreign types `[unsigned-]int32' and `[unsigned-]integer32'
406- added SRFI-17 setters for many accessors of the core libraries
407- tinyclos: added a couple of missing classes for core library structures
408- `let[*]-values' is now SRFI-11 compliant
409- the finalizer-table is now resized dynamically, which speeds up code that uses
410  very many finalizers [Thanks to Zbigniew Szadkowski]
411- reloading compiled code dynamically does basically work (but still leaks memory)
412- the manual contains a section on pattern matching
413- libffi is used by default, when available
414- CHICKEN has now experimental support for the "CMake" build system <>
415  Many thanks to Bill Hoffmann from Kitware and Brandon van Every for helping with this

420Thanks, Sergey!
422Many thanks Jean-Francois Bignolles, Patrick Brannan, Adam Buchbinder, Hans Bulfone, Category 5,
423John Cowan, datrus, Guillaume Germaine, Mario Domenech Goulart, Daniel B. Faken, Andrey Fomichev,
424Jarod Eells, Sven Hartrumpf, David Janssens, Daishi Kato, Levi Pearson, Pupeno, Eric Raible, Benedikt
425Rosenau, Reed Sheridan, Zbigniew Szadkowski and Mark Wutka for their helpful contributions,
426suggestions and bug reports!
428Special thanks to Kon Lovett for fixing countless open issues and many useful sugestions.
433- Many bugfixes
434- The read-syntax `#+X Y' is provided as a shorthand for `(cond-expand (X Y) (else))'
435- `foreign-parse' and `foreign-parse/spec' have been removed
436- lolevel: Executable byte-vector stuff has been removed
437- SRFIs 28, 31, 62 and 69 are now officially supported
438- New compiler option `-extension' simplifies static compilation of eggs
439- csc: changed `-E' to `-P', `-E' is now an alias for `-extension'
440- Embedding:
441  * All the `entry-point' related things have been removed, as has been `define-embedded',
442    calling Scheme from C is now exclusively done with callbacks
443  * Integrated boilerplate embedding API into the `eval' unit
444  * Added `CHICKEN_continue' API function
445  * Default "stub" toplevel (`CHICKEN_default_toplevel') allows embedding without a
446    separate Scheme file
447  * Different stack-levels during invocation of CHICKEN_run or callbacks could result
448    in crashes - this is now detected (or can be checked manually)
449- Added extension-specifier `(version ...)'
450- New FFI macros `foreign-declare', `foreign-parse' and `foreign-parse/declare' replace
451  the declaration-specifiers of the same name
452- Hash-table resizing was ridiculously slow, and should now be much faster
453- `define-foreign-record' handles recursive structures
454- `require-extension' is now available by default, and so can be used with the
455  plain Scheme evaluator
456- Procedures now contain some basic debug information, unless a file was compiled
457  with `-no-lambda-info'
458- compiler: `-debug-level 2' is now the default (enables trace- and lambda-info)
459- chicken-setup:
460  * handles direct downloads from arbitrary URLs
461  * HTML documentation for eggs can now be included into the egg and will be installed
462    in the repository (using the `documentation' info-property)
463  * `chicken-setup -docindex' shows path of generated documentation index for all
464    installed eggs
465- extras:
466  * SRFI-69 is now fully supported, note that THIS WILL BREAK EXISTING CODE, since
467    the API is not compatible to the previous one
468  * `clear-hash-table!', `get' and `put!' are gone
469  * `read-file' accepts optional reader procedure and max count
470  * `read-lines' accepts filename instead of port
471- library:
472  * `signum' is now exactness-preserving
473  * `procedure-information' returns some basic debug info for a given procedure
474  * Added `(warning MESSAGE ARGUMENTS ...)'
475  * `(promise? X)'
476- posix:
477  * `(current-directory DIR)' is equivalent to `(change-directory DIR)'
478- regex:
479  * `pattern->regexp' has been renamed to `glob->regexp'
480- The `format' library unit has been removed from the base system and is noww available
481  separately
482- SRFI-17, on the other hand has been moved into the base system
483- String literals and the print-names of symbol literals are now allocated in static
484  (non-GC'd) memory
485- If static or shared build is disabled, no `...-static' executables will be generated
488Many thanks to Ashley Bone, Thomas Chust, John Cowan, Alejandro Forero Cuervo, Daniel Faken, Sven
489Hartrumpf, Daishi Kato, Sergey Khorev, Kon Lovett, Gene Pavlovsky, Reed Sheridan and Ed Watkeys for
490their helpful contributions, suggestions and bug reports!
495- Many bugfixes
496- Loads of minor improvements (better error messages, more warnings, more error
497  checks, etc.)
498- On systems supported by the "libffi" library, the 128-argument limit can
499  be exceeded (currently to an arbitrary maximum of 1000). To take advantage
500  of this, add `--with-libffi' to the configuration options when building
501  chicken
502- The `libsrfi-chicken' and `libstuffed-chicken' libraries have been folded
503  into `libchicken', so only a single library is linked with generated
504  executables, which greatly simplifies and speeds up the build process.
505  It is recommended to remove any traced of `libstuffed-chicken.*' and
506  `libsrfi-chicken.*' before installing a new release. This requires also
507  to reinstall all eggs (extension libraries).
508- The compiler is able to inline more procedure calls
509- Implicit non-multival continuations (like in `begin' or 'let') accept multiple
510  values and discard all but the first value
511- finalization should actually work now and is much more efficient (unless
512  used excessively)
513- csi:
514  `advise' has been removed
515  `-eval' implies `-batch' and `-quiet'
516  added `-require-extension'
517  short option names are now supported and may be collapsed, if unambigous
518- New runtime options:
519  -:b (enter REPL on error)
520  -:B (ring bell on every major GC)
521  -:fNNN (set pending finalizer maximum limit)
522- New compiler options:
523  -accumulate-profile
524  -inline
525  -inline-limit
526  -emit-external-prototypes-first
527- The compiler-option `-require-for-syntax' has been renamed to `-require-extension'
528  and is the same as putting a `(require-extension ...)' form directly into the code
529- Removed compiler- and interpreter option `-no-feature'
530- New declarations:
531  (lambda-lift)
532  ([not] inline)
533  (inline-limit LIMIT)
534  (emit-external-prototypes-first)
535  ([not] check-c-syntax)
536- `foreign-callback-lambda[*]' has been renamed to `foreign-safe-lambda[*]' - the
537  old names are still valid but deprecated
538- New foreign type specifier `scheme-pointer' (the same as `pointer', which is
539  deprecated now)
540- Easy FFI:
541  `___scheme_pointer' and `___byte_vector' pseudo types
542  `___pointer' and `___length' markers
543  `default_renaming' and `opaque' pseudo declarations
544  `___inout' and `___out' argument markers work also for C++ reference types
545  Recognizes `C_word' and `size_t'
546- The reader supports selective case sensitive/insensitive reading using the
547  `#cs...' and `#ci...' syntax (as supported in PLT Scheme)
548- `\uXXXX' and `\UXXXXXXXX' escape-sequences for string literals
549- `#\UXXXXXXXX' character literal syntax
550- `\v', `\a' and `\f' escape sequences and `#\delete', `#\esc', `#\alarm', `#\vtab'
551  and `#\nul' character literals
552- `chicken-setup' supports proxy connections via the `-proxy' option
553- library:
554  (set-dynamic-load-mode! MODE)
555  `(end-of-file)' has been removed (use `#!eof' instead)
556- The alternative continuation API described in Marc Feeley's paper
557  "A better API for first class continuations" is supported natively:
558  (continuation-capture PROC)
559  (continuation-graft K THUNK)
560  (continuation-return K VALUE ...)
561  (continuation? X)
562- `foreign-primitive' and `define-extension' macros
563- tinyclos:
564  (instance-of? X)
565  `define-method' specializes on all arguments and allows DSSSL keyword argument lists
566- eval:
567  (set-dispatch-read-syntax! CHAR PROC)
568- extras:
569  (hash-table-update! HT KEY PROC INIT)
570  (hash-table-exists? HT KEY)
571  (hash-table-values HT)
572  (hash-table-keys HT)
573  (alist->hash-table ALIST [TEST SIZE])
574  `hash-table->list' has been renamed to `hash-table->alist
575  `hash-table-for-each' takes the arguments in reversed order (the old order is still
576  valid but deprecated)
577  Hash-tables support now user-defined hash functions
578- posix:
579  (file-link OLD NEW)
580  (symbolic-link? FILENAME)
581  (regular-file? FILENAME)
582  errno/exist
583  `process' and `process-execute' allow passing an environment
584- regex:
585  (regexp-escape STR)
586- tcp:
587  (tcp-listener-fileno LISTENER)
588- utils:
589  (port-for-each FN THUNK)
590  (port-map FN THUNK)
591- On Windows, the batch file `win-install.bat' can be used to install the system
592  into the desired location
593- Building Chicken on Windows with the free development tools from Microsoft (VCToolkit,
594  Platform Core SDK) has been tested and is documented in the file `vctk-install.txt'
595- The `-script-meta' option has been removed
596- The srfi-25 and srfi-37 library units and the test-infrastructure facility have been
597  removed from the core system and is now separately available as an extensions (eggs)
598- The syntax-case macro and module system has been removed and also available as an
599  extension. This implies that all compiler- and interpreter options related to hygienic
600  macros and syntax-case are gone as well.
601- All strictness compiler- and interpreter options (and the `strict-reader' parameter)
602  have been removed
603- the `examples' directory and its contents have been removed from the distribution
