292Special thanks to Kon Lovett for many improvements made in the posix
298- Bugfixes
299- CHICKEN can now be built using CMake <>, in fact CMake
300  is required to built CHICKEN from sources on Windows with the Microsoft
301  tools
302- the whole build process has been cleaned up and simplified
303- the "easyffi" and "tinyclos" library units have been removed from the base
304  system and are now available as separate extensions
305- the deprecated "set-dispatch-read-syntax!" has been removed
306- Will Farr cleaned up the behaviour of number-type specific numeric operations
307  ("fx..."/"fp...") with respect to safe/unsafe mode
308- added "(finite? NUMBER)"
309- the "$" macro moved into its own separate extension
310- the values of "software-type", "software-version", "machine-type" and "machine-byte-order"
311  are now registered as features and can be tested using "cond-expand" or "#+"

313- chicken-setup: added "-test" option
315Special thanks to Brandon Van Every, who put considerable effort into the
316CHICKEN build system and who ported it to CMake completely from scratch.
317The installation instructions and build file are extensively documented and may
318serve as a tutorial for creating non-trivial software projects with CMake.
319Thanks, Brandon! Also thanks to Bill Hoffmann and Brad King from Kitware
320for their support.
322Many thanks to Peter Bex, Toby Butzon, Thomans Chust, John Cowan, Alejandro Forero Cuervo,

329- Bugfixes galore
330- compiler:
331  * added support for the generation of "export" files through the "-emit-exports" option
332  * new option `-check-imports' (csc: `-G') checks for unimported symbols and can be quite
333    helpful in finding unbound variable errors (this requires all extensions ("eggs") to be
334    adapted to this new feature, a process which isn't complete yet)
335  * new declarations `emit-exports', `constant' and `import'
336  * new option `-disable-warning' and declaration `disable-warning'

347  * `foreign-safe-wrapper' has been deprecated
348- Slight reorganization of TinyCLOS and match macros and support code
349- `thread-join!' has been generalized to allow a thread to have multiple results
350- Renamed `thread-deliver-signal!' to `thread-signal!' and `invalid-procedure-call-handler'
351  to `set-procedure-call-handler!'
352- The system can be configured to add an extra slot to symbol objects
353- Another configuration option enables GC of unused symbols by default
354- The extension repository is now versioned to catch binary incompatible
355  installations, this requires to either move all installed extensions to the
356  new location ("$prefix/lib/chicken/1") or reinstall them
357- Now supports SRFI-61 (extended `cond')
358- Added procedures `load-relative', `tcp-buffer-size`, `string-chomp'
359- trivial implementations of `real-part', `imag-part', `angle' and `magnitude' have
360  been added to the library to allow more portable code
361- Breakpoints and single-stepping of compiled code on the function-level, new
362  procedures `breakpoint' and `singlestep'

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

398    all .setup scripts in the current directory are executed
399  * added `setup-build-directory' and `setup-root-directory' parameters
400  * helper procedures `copy-file', `move-file', `remove-file' and `create-directory'

403- new toplevel commands in csi can be defined with the `toplevel-command' procedure
404- `extension-info' has been renamed to `extension-information'. The old name is
405  still available, but deprecated
406- `print-backtrace' has been renamed to `print-call-chain'. The old name is still

433- new foreign types `[unsigned-]int32' and `[unsigned-]integer32'
434- added SRFI-17 setters for many accessors of the core libraries
435- tinyclos: added a couple of missing classes for core library structures
436- `let[*]-values' is now SRFI-11 compliant
437- the finalizer-table is now resized dynamically, which speeds up code that uses
438  very many finalizers [Thanks to Zbigniew Szadkowski]
439- reloading compiled code dynamically does basically work (but still leaks memory)
440- the manual contains a section on pattern matching

470    calling Scheme from C is now exclusively done with callbacks
471  * Integrated boilerplate embedding API into the `eval' unit
472  * Added `CHICKEN_continue' API function
473  * Default "stub" toplevel (`CHICKEN_default_toplevel') allows embedding without a
474    separate Scheme file
475  * Different stack-levels during invocation of CHICKEN_run or callbacks could result
476    in crashes - this is now detected (or can be checked manually)

483  plain Scheme evaluator
484- Procedures now contain some basic debug information, unless a file was compiled
485  with `-no-lambda-info'
486- compiler: `-debug-level 2' is now the default (enables trace- and lambda-info)
487- chicken-setup:
488  * handles direct downloads from arbitrary URLs
489  * HTML documentation for eggs can now be included into the egg and will be installed
490    in the repository (using the `documentation' info-property)
491  * `chicken-setup -docindex' shows path of generated documentation index for all
492    installed eggs
493- extras:
494  * SRFI-69 is now fully supported, note that THIS WILL BREAK EXISTING CODE, since

509  separately
510- SRFI-17, on the other hand has been moved into the base system
511- String literals and the print-names of symbol literals are now allocated in static
512  (non-GC'd) memory
513- If static or shared build is disabled, no `...-static' executables will be generated
516Many thanks to Ashley Bone, Thomas Chust, John Cowan, Alejandro Forero Cuervo, Daniel Faken, Sven
517Hartrumpf, Daishi Kato, Sergey Khorev, Kon Lovett, Gene Pavlovsky, Reed Sheridan and Ed Watkeys for
518their helpful contributions, suggestions and bug reports!
523- Many bugfixes
524- Loads of minor improvements (better error messages, more warnings, more error
525  checks, etc.)
526- On systems supported by the "libffi" library, the 128-argument limit can
527  be exceeded (currently to an arbitrary maximum of 1000). To take advantage
528  of this, add `--with-libffi' to the configuration options when building
529  chicken
530- The `libsrfi-chicken' and `libstuffed-chicken' libraries have been folded
531  into `libchicken', so only a single library is linked with generated
532  executables, which greatly simplifies and speeds up the build process.
533  It is recommended to remove any traced of `libstuffed-chicken.*' and
534  `libsrfi-chicken.*' before installing a new release. This requires also
535  to reinstall all eggs (extension libraries).
536- The compiler is able to inline more procedure calls
537- Implicit non-multival continuations (like in `begin' or 'let') accept multiple
538  values and discard all but the first value
539- finalization should actually work now and is much more efficient (unless
540  used excessively)
541- csi:
542  `advise' has been removed
543  `-eval' implies `-batch' and `-quiet'
544  added `-require-extension'
545  short option names are now supported and may be collapsed, if unambigous
546- New runtime options:
547  -:b (enter REPL on error)
548  -:B (ring bell on every major GC)
549  -:fNNN (set pending finalizer maximum limit)
550- New compiler options:
551  -accumulate-profile
552  -inline
553  -inline-limit
554  -emit-external-prototypes-first
555- The compiler-option `-require-for-syntax' has been renamed to `-require-extension'
556  and is the same as putting a `(require-extension ...)' form directly into the code
557- Removed compiler- and interpreter option `-no-feature'
558- New declarations:
559  (lambda-lift)
560  ([not] inline)
561  (inline-limit LIMIT)
562  (emit-external-prototypes-first)
563  ([not] check-c-syntax)
564- `foreign-callback-lambda[*]' has been renamed to `foreign-safe-lambda[*]' - the
565  old names are still valid but deprecated
566- New foreign type specifier `scheme-pointer' (the same as `pointer', which is
567  deprecated now)
568- Easy FFI:
569  `___scheme_pointer' and `___byte_vector' pseudo types
570  `___pointer' and `___length' markers
571  `default_renaming' and `opaque' pseudo declarations
572  `___inout' and `___out' argument markers work also for C++ reference types
573  Recognizes `C_word' and `size_t'
574- The reader supports selective case sensitive/insensitive reading using the
575  `#cs...' and `#ci...' syntax (as supported in PLT Scheme)
576- `\uXXXX' and `\UXXXXXXXX' escape-sequences for string literals
577- `#\UXXXXXXXX' character literal syntax
578- `\v', `\a' and `\f' escape sequences and `#\delete', `#\esc', `#\alarm', `#\vtab'
579  and `#\nul' character literals
580- `chicken-setup' supports proxy connections via the `-proxy' option
581- library:
582  (set-dynamic-load-mode! MODE)
583  `(end-of-file)' has been removed (use `#!eof' instead)
584- The alternative continuation API described in Marc Feeley's paper
585  "A better API for first class continuations" is supported natively:
586  (continuation-capture PROC)
587  (continuation-graft K THUNK)
588  (continuation-return K VALUE ...)
589  (continuation? X)
590- `foreign-primitive' and `define-extension' macros
591- tinyclos:
592  (instance-of? X)
593  `define-method' specializes on all arguments and allows DSSSL keyword argument lists
594- eval:
595  (set-dispatch-read-syntax! CHAR PROC)
596- extras:
597  (hash-table-update! HT KEY PROC INIT)
598  (hash-table-exists? HT KEY)
599  (hash-table-values HT)
600  (hash-table-keys HT)
601  (alist->hash-table ALIST [TEST SIZE])
602  `hash-table->list' has been renamed to `hash-table->alist
603  `hash-table-for-each' takes the arguments in reversed order (the old order is still
604  valid but deprecated)
605  Hash-tables support now user-defined hash functions
606- posix:
607  (file-link OLD NEW)
608  (symbolic-link? FILENAME)
609  (regular-file? FILENAME)
610  errno/exist
611  `process' and `process-execute' allow passing an environment
612- regex:
613  (regexp-escape STR)
614- tcp:
615  (tcp-listener-fileno LISTENER)
616- utils:
617  (port-for-each FN THUNK)
618  (port-map FN THUNK)
619- On Windows, the batch file `win-install.bat' can be used to install the system
620  into the desired location
621- Building Chicken on Windows with the free development tools from Microsoft (VCToolkit,
622  Platform Core SDK) has been tested and is documented in the file `vctk-install.txt'
623- The `-script-meta' option has been removed
624- The srfi-25 and srfi-37 library units and the test-infrastructure facility have been
625  removed from the core system and is now separately available as an extensions (eggs)
626- The syntax-case macro and module system has been removed and also available as an
627  extension. This implies that all compiler- and interpreter options related to hygienic
628  macros and syntax-case are gone as well.
629- All strictness compiler- and interpreter options (and the `strict-reader' parameter)
630  have been removed
631- the `examples' directory and its contents have been removed from the distribution
