325build process.
327Special thanks to Kon Lovett for many improvements made in the posix
333- Bugfixes
334- CHICKEN can now be built using CMake <>, in fact CMake
335  is required to built CHICKEN from sources on Windows with the Microsoft
336  tools
337- the whole build process has been cleaned up and simplified
338- the "easyffi" and "tinyclos" library units have been removed from the base
339  system and are now available as separate extensions
340- the deprecated "set-dispatch-read-syntax!" has been removed
341- Will Farr cleaned up the behaviour of number-type specific numeric operations
342  ("fx..."/"fp...") with respect to safe/unsafe mode
343- added "(finite? NUMBER)"
344- the "$" macro moved into its own separate extension
345- the values of "software-type", "software-version", "machine-type" and "machine-byte-order"

348- chicken-setup: added "-test" option
350Special thanks to Brandon Van Every, who put considerable effort into the
351CHICKEN build system and who ported it to CMake completely from scratch.
352The installation instructions and build file are extensively documented and may
353serve as a tutorial for creating non-trivial software projects with CMake.
354Thanks, Brandon! Also thanks to Bill Hoffmann and Brad King from Kitware
355for their support.

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

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

403  the installation path prefix in case you want to install and run multiple instances/versions
404  of CHICKEN or install on a shared network
405- csc: added `-dry-run' option
406- removed `-split...' options (and the ability to generate multiple C files from a single
407  Scheme file)
408- `crictical-section', `disable-interrupts' and `enable-interrupts' shouldn't be used from
409  now on (deprecated), use SRFI-18 mutexes instead

431  * detects whether eggs are gzipped or not and accepts ungzipped eggs
432  * if no other actions are specified and no eggs are given on the command line, then
433    all .setup scripts in the current directory are executed
434  * added `setup-build-directory' and `setup-root-directory' parameters
435  * helper procedures `copy-file', `move-file', `remove-file' and `create-directory'

437  macros have been replaced byy the toplevel commands `,tr' and `,utr'
438- new toplevel commands in csi can be defined with the `toplevel-command' procedure
439- `extension-info' has been renamed to `extension-information'. The old name is
440  still available, but deprecated
441- `print-backtrace' has been renamed to `print-call-chain'. The old name is still
442  available (and deprecated)
443- `transcript-on' and `transcript-off' are no longer supported
444- New macro `define-for-syntax'
445- library:
446  (get-call-chain [DEPTH])

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

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

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