145  compiling extensions in "host" mode when using a cross-compiling
146  chicken

269build process.
271Special thanks to Kon Lovett for many improvements made in the posix
277- Bugfixes
278- CHICKEN can now be built using CMake <>, in fact CMake
279  is required to built CHICKEN from sources on Windows with the Microsoft
280  tools
281- the whole build process has been cleaned up and simplified
282- the "easyffi" and "tinyclos" library units have been removed from the base
283  system and are now available as separate extensions
284- the deprecated "set-dispatch-read-syntax!" has been removed
285- Will Farr cleaned up the behaviour of number-type specific numeric operations
286  ("fx..."/"fp...") with respect to safe/unsafe mode
287- added "(finite? NUMBER)"
288- the "$" macro moved into its own separate extension
289- the values of "software-type", "software-version", "machine-type" and "machine-byte-order"

292- chicken-setup: added "-test" option
294Special thanks to Brandon Van Every, who put considerable effort into the
295CHICKEN build system and who ported it to CMake completely from scratch.
296The installation instructions and build file are extensively documented and may
297serve as a tutorial for creating non-trivial software projects with CMake.
298Thanks, Brandon! Also thanks to Bill Hoffmann and Brad King from Kitware
299for their support.
301Many thanks to Peter Bex, Toby Butzon, Thomans Chust, John Cowan, Alejandro Forero Cuervo,

308- Bugfixes galore
309- compiler:
310  * added support for the generation of "export" files through the "-emit-exports" option
311  * new option `-check-imports' (csc: `-G') checks for unimported symbols and can be quite
312    helpful in finding unbound variable errors (this requires all extensions ("eggs") to be
313    adapted to this new feature, a process which isn't complete yet)
314  * new declarations `emit-exports', `constant' and `import'
315  * new option `-disable-warning' and declaration `disable-warning'
316  * new options `-release' and `-import'

320  * added `-eval' option
321  * added parameters `setup-install-flag' and `setup-verbose-flag'

330  to `set-procedure-call-handler!'
331- The system can be configured to add an extra slot to symbol objects
332- Another configuration option enables GC of unused symbols by default
333- The extension repository is now versioned to catch binary incompatible
334  installations, this requires to either move all installed extensions to the
335  new location ("$prefix/lib/chicken/1") or reinstall them
336- Now supports SRFI-61 (extended `cond')
337- Added procedures `load-relative', `tcp-buffer-size`, `string-chomp'
338- trivial implementations of `real-part', `imag-part', `angle' and `magnitude' have
339  been added to the library to allow more portable code
340- Breakpoints and single-stepping of compiled code on the function-level, new
341  procedures `breakpoint' and `singlestep'
342- csi: new toplevel commands `,info', `,step', `,br', `,ubr', `,breakall', `,breakonly',
343  `,exn' and `,c'
344- csi: `set-describer!' allows definition of custom output for the `,d' command
345- Added `integer64' foreign type specifier
346- The environment variable "CHICKEN_PREFIX" allows (together with "CHICKEN_REPOSITORY") overriding
347  the installation path prefix in case you want to install and run multiple instances/versions
348  of CHICKEN or install on a shared network
349- csc: added `-dry-run' option
350- removed `-split...' options (and the ability to generate multiple C files from a single
351  Scheme file)
352- `crictical-section', `disable-interrupts' and `enable-interrupts' shouldn't be used from
353  now on (deprecated), use SRFI-18 mutexes instead
355Many thanks to Nico Amtsberg, Arto Bendiken, Jean-Francois Bignolles, Peter Busser, Thomas Chust,
356John Cowan, Alejandro Forero Cuervo, Jaarod Eells, Brandon van Every, Graham Fawcett, Mario Domenech

376  * if no other actions are specified and no eggs are given on the command line, then
377    all .setup scripts in the current directory are executed
378  * added `setup-build-directory' and `setup-root-directory' parameters
379  * helper procedures `copy-file', `move-file', `remove-file' and `create-directory'
380- csi commands `,s', `,l' and `,ln' accept multiple inputs, the `trace'/`untrace'
381  macros have been replaced byy the toplevel commands `,tr' and `,utr'
382- new toplevel commands in csi can be defined with the `toplevel-command' procedure
383- `extension-info' has been renamed to `extension-information'. The old name is
384  still available, but deprecated
385- `print-backtrace' has been renamed to `print-call-chain'. The old name is still
386  available (and deprecated)
387- `transcript-on' and `transcript-off' are no longer supported
388- New macro `define-for-syntax'
389- library:
390  (get-call-chain [DEPTH])
391  (current-read-table)
392  (copy-read-table READ-TABLE)
393  (current-gc-milliseconds)
394  `print-error-message' writes now to the current output-port, not the error port
395  `number-string' does now a slightly better job converting large exact integers
396  with non-decimal base
397- extras:
398  (each PROC ...)
399  `hash-table-ref' throws (exn access) on error
400- posix:

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

433suggestions and bug reports!
435Special thanks to Kon Lovett for fixing countless open issues and many useful sugestions.
440- Many bugfixes

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