321build process.
323Special thanks to Kon Lovett for many improvements made in the posix
329- Bugfixes
330- CHICKEN can now be built using CMake <>, in fact CMake
331  is required to built CHICKEN from sources on Windows with the Microsoft
332  tools
333- the whole build process has been cleaned up and simplified
334- the "easyffi" and "tinyclos" library units have been removed from the base
335  system and are now available as separate extensions
336- the deprecated "set-dispatch-read-syntax!" has been removed
337- Will Farr cleaned up the behaviour of number-type specific numeric operations
338  ("fx..."/"fp...") with respect to safe/unsafe mode
339- added "(finite? NUMBER)"
340- the "$" macro moved into its own separate extension
341- the values of "software-type", "software-version", "machine-type" and "machine-byte-order"
342  are now registered as features and can be tested using "cond-expand" or "#+"

344- chicken-setup: added "-test" option
346Special thanks to Brandon Van Every, who put considerable effort into the
347CHICKEN build system and who ported it to CMake completely from scratch.
348The installation instructions and build file are extensively documented and may
349serve as a tutorial for creating non-trivial software projects with CMake.
350Thanks, Brandon! Also thanks to Bill Hoffmann and Brad King from Kitware
351for their support.
353Many thanks to Peter Bex, Toby Butzon, Thomans Chust, John Cowan, Alejandro Forero Cuervo,

360- Bugfixes galore
361- compiler:
362  * added support for the generation of "export" files through the "-emit-exports" option
363  * new option `-check-imports' (csc: `-G') checks for unimported symbols and can be quite
364    helpful in finding unbound variable errors (this requires all extensions ("eggs") to be
365    adapted to this new feature, a process which isn't complete yet)
366  * new declarations `emit-exports', `constant' and `import'
367  * new option `-disable-warning' and declaration `disable-warning'

382  to `set-procedure-call-handler!'
383- The system can be configured to add an extra slot to symbol objects
384- Another configuration option enables GC of unused symbols by default
385- The extension repository is now versioned to catch binary incompatible
386  installations, this requires to either move all installed extensions to the
387  new location ("$prefix/lib/chicken/1") or reinstall them
388- Now supports SRFI-61 (extended `cond')
389- Added procedures `load-relative', `tcp-buffer-size`, `string-chomp'
390- trivial implementations of `real-part', `imag-part', `angle' and `magnitude' have
391  been added to the library to allow more portable code
392- Breakpoints and single-stepping of compiled code on the function-level, new
393  procedures `breakpoint' and `singlestep'

397- Added `integer64' foreign type specifier
398- The environment variable "CHICKEN_PREFIX" allows (together with "CHICKEN_REPOSITORY") overriding
399  the installation path prefix in case you want to install and run multiple instances/versions
400  of CHICKEN or install on a shared network
401- csc: added `-dry-run' option
402- removed `-split...' options (and the ability to generate multiple C files from a single
403  Scheme file)
404- `crictical-section', `disable-interrupts' and `enable-interrupts' shouldn't be used from
405  now on (deprecated), use SRFI-18 mutexes instead

426- chicken-setup:
427  * detects whether eggs are gzipped or not and accepts ungzipped eggs
428  * if no other actions are specified and no eggs are given on the command line, then
429    all .setup scripts in the current directory are executed
430  * added `setup-build-directory' and `setup-root-directory' parameters
431  * helper procedures `copy-file', `move-file', `remove-file' and `create-directory'
432- csi commands `,s', `,l' and `,ln' accept multiple inputs, the `trace'/`untrace'
433  macros have been replaced byy the toplevel commands `,tr' and `,utr'
434- new toplevel commands in csi can be defined with the `toplevel-command' procedure
435- `extension-info' has been renamed to `extension-information'. The old name is
436  still available, but deprecated
437- `print-backtrace' has been renamed to `print-call-chain'. The old name is still
438  available (and deprecated)
439- `transcript-on' and `transcript-off' are no longer supported
440- New macro `define-for-syntax'
441- library:
442  (get-call-chain [DEPTH])

445  (current-gc-milliseconds)
446  `print-error-message' writes now to the current output-port, not the error port
447  `number-string' does now a slightly better job converting large exact integers
448  with non-decimal base
449- extras:
450  (each PROC ...)
451  `hash-table-ref' throws (exn access) on error
452- posix:

460- `set-dispatch-read-syntax!' has been renamed to `set-sharp-read-syntax!' (the old
461  name is still available but deprecated)
462- evaluated code generates call-trace information (as compiled code does), which
463  results in much better back-traces.
464- new foreign types `[unsigned-]int32' and `[unsigned-]integer32'
465- added SRFI-17 setters for many accessors of the core libraries
466- tinyclos: added a couple of missing classes for core library structures
467- `let[*]-values' is now SRFI-11 compliant
468- the finalizer-table is now resized dynamically, which speeds up code that uses
469  very many finalizers [Thanks to Zbigniew Szadkowski]
470- reloading compiled code dynamically does basically work (but still leaks memory)
471- the manual contains a section on pattern matching
472- libffi is used by default, when available

485suggestions and bug reports!
487Special thanks to Kon Lovett for fixing countless open issues and many useful sugestions.

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