--
--2.5
--
--- Bugfixes
--- CHICKEN can now be built using CMake <http://www.cmake.org>, in fact CMake
--  is required to built CHICKEN from sources on Windows with the Microsoft 
--  tools
--- the whole build process has been cleaned up and simplified
--- the "easyffi" and "tinyclos" library units have been removed from the base
--  system and are now available as separate extensions
--- the deprecated "set-dispatch-read-syntax!" has been removed
--- Will Farr cleaned up the behaviour of number-type specific numeric operations
--  ("fx..."/"fp...") with respect to safe/unsafe mode
--- added "(finite? NUMBER)"
--- the "$" macro moved into its own separate extension
--- the values of "software-type", "software-version", "machine-type" and "machine-byte-order"
--  are now registered as features and can be tested using "cond-expand" or "#+"
--- all tools now support the "-release" option
--- chicken-setup: added "-test" option
--
--Special thanks to Brandon Van Every, who put considerable effort into the
--CHICKEN build system and who ported it to CMake completely from scratch.
--The installation instructions and build file are extensively documented and may
--serve as a tutorial for creating non-trivial software projects with CMake.
--Thanks, Brandon! Also thanks to Bill Hoffmann and Brad King from Kitware
--for their support.

--
--
--2.41
--
--- Bugfixes galore
--- compiler: 
--  * added support for the generation of "export" files through the "-emit-exports" option
--  * new option `-check-imports' (csc: `-G') checks for unimported symbols and can be quite
--    helpful in finding unbound variable errors (this requires all extensions ("eggs") to be
--    adapted to this new feature, a process which isn't complete yet)
--  * new declarations `emit-exports', `constant' and `import'
--  * new option `-disable-warning' and declaration `disable-warning'
--  * new options `-release' and `-import'
--- chicken-setup:

--  * option `-check' checks for extension upgrades
--  * added `-eval' option
--  * added parameters `setup-install-flag' and `setup-verbose-flag'
--- FFI: 
--  * added the handy `$' macro, which lets you do foreign calls directly without declaring
--    a placeholder procedure
--  * `define-foreign-enum' for treating C enums as symbol-sets
--  * `foreign-safe-wrapper' has been deprecated
--- Slight reorganization of TinyCLOS and match macros and support code
--- `thread-join!' has been generalized to allow a thread to have multiple results
--- Renamed `thread-deliver-signal!' to `thread-signal!' and `invalid-procedure-call-handler'
--  to `set-procedure-call-handler!' 
--- The system can be configured to add an extra slot to symbol objects
--- Another configuration option enables GC of unused symbols by default
--- The extension repository is now versioned to catch binary incompatible
--  installations, this requires to either move all installed extensions to the
--  new location ("$prefix/lib/chicken/1") or reinstall them
--- Now supports SRFI-61 (extended `cond')
--- Added procedures `load-relative', `tcp-buffer-size`, `string-chomp'
--- trivial implementations of `real-part', `imag-part', `angle' and `magnitude' have 
--  been added to the library to allow more portable code
--- Breakpoints and single-stepping of compiled code on the function-level, new
--  procedures `breakpoint' and `singlestep'
--- csi: new toplevel commands `,info', `,step', `,br', `,ubr', `,breakall', `,breakonly',
--  `,exn' and `,c'
--- csi: `set-describer!' allows definition of custom output for the `,d' command
--- Added `integer64' foreign type specifier
--- The environment variable "CHICKEN_PREFIX" allows (together with "CHICKEN_REPOSITORY") overriding
--  the installation path prefix in case you want to install and run multiple instances/versions 
--  of CHICKEN or install on a shared network
--- csc: added `-dry-run' option
--- removed `-split...' options (and the ability to generate multiple C files from a single
--  Scheme file)
--- `crictical-section', `disable-interrupts' and `enable-interrupts' shouldn't be used from
--  now on (deprecated), use SRFI-18 mutexes instead

--  * added `setup-build-directory' and `setup-root-directory' parameters
--  * helper procedures `copy-file', `move-file', `remove-file' and `create-directory'

--- added SRFI-17 setters for many accessors of the core libraries
--- tinyclos: added a couple of missing classes for core library structures

--
--2.2

--- lolevel: Executable byte-vector stuff has been removed
--- SRFIs 28, 31, 62 and 69 are now officially supported
--- New compiler option `-extension' simplifies static compilation of eggs
--- csc: changed `-E' to `-P', `-E' is now an alias for `-extension'
--- Embedding:
--  * All the `entry-point' related things have been removed, as has been `define-embedded',
--    calling Scheme from C is now exclusively done with callbacks
--  * Integrated boilerplate embedding API into the `eval' unit
--  * Added `CHICKEN_continue' API function
--  * Default "stub" toplevel (`CHICKEN_default_toplevel') allows embedding without a
--    separate Scheme file 
--  * Different stack-levels during invocation of CHICKEN_run or callbacks could result
--    in crashes - this is now detected (or can be checked manually)
--- Added extension-specifier `(version ...)'
--- New FFI macros `foreign-declare', `foreign-parse' and `foreign-parse/declare' replace
--  the declaration-specifiers of the same name
--- Hash-table resizing was ridiculously slow, and should now be much faster
--- `define-foreign-record' handles recursive structures
--- `require-extension' is now available by default, and so can be used with the
--  plain Scheme evaluator
--- Procedures now contain some basic debug information, unless a file was compiled
--  with `-no-lambda-info'
--- compiler: `-debug-level 2' is now the default (enables trace- and lambda-info)
--- chicken-setup: 
--  * handles direct downloads from arbitrary URLs
--  * HTML documentation for eggs can now be included into the egg and will be installed
--    in the repository (using the `documentation' info-property)
--  * `chicken-setup -docindex' shows path of generated documentation index for all 
--    installed eggs
--- extras: 
--  * SRFI-69 is now fully supported, note that THIS WILL BREAK EXISTING CODE, since
--    the API is not compatible to the previous one
--  * `clear-hash-table!', `get' and `put!' are gone

--
--
--2.0
--
--- Many bugfixes 
--- Loads of minor improvements (better error messages, more warnings, more error 
--  checks, etc.)
--- On systems supported by the "libffi" library, the 128-argument limit can
--  be exceeded (currently to an arbitrary maximum of 1000). To take advantage
--  of this, add `--with-libffi' to the configuration options when building
--  chicken
--- The `libsrfi-chicken' and `libstuffed-chicken' libraries have been folded
--  into `libchicken', so only a single library is linked with generated
--  executables, which greatly simplifies and speeds up the build process.
--  It is recommended to remove any traced of `libstuffed-chicken.*' and 
--  `libsrfi-chicken.*' before installing a new release. This requires also
--  to reinstall all eggs (extension libraries).
--- The compiler is able to inline more procedure calls
--- Implicit non-multival continuations (like in `begin' or 'let') accept multiple 
--  values and discard all but the first value
--- finalization should actually work now and is much more efficient (unless
--  used excessively)
--- csi: 
--  `advise' has been removed
--  `-eval' implies `-batch' and `-quiet'
--  added `-require-extension'
--  short option names are now supported and may be collapsed, if unambigous
--- New runtime options:
--  -:b (enter REPL on error)
--  -:B (ring bell on every major GC)
--  -:fNNN (set pending finalizer maximum limit)
--- New compiler options:
--  -accumulate-profile
--  -inline
--  -inline-limit
--  -emit-external-prototypes-first
--- The compiler-option `-require-for-syntax' has been renamed to `-require-extension'
--  and is the same as putting a `(require-extension ...)' form directly into the code
--- Removed compiler- and interpreter option `-no-feature'
--- New declarations:
--  (lambda-lift)
--  ([not] inline)
--  (inline-limit LIMIT)
--  (emit-external-prototypes-first)
--  ([not] check-c-syntax)
--- `foreign-callback-lambda[*]' has been renamed to `foreign-safe-lambda[*]' - the
--  old names are still valid but deprecated
--- New foreign type specifier `scheme-pointer' (the same as `pointer', which is 
--  deprecated now)
--- Easy FFI: 
--  `___scheme_pointer' and `___byte_vector' pseudo types
--  `___pointer' and `___length' markers
--  `default_renaming' and `opaque' pseudo declarations
--  `___inout' and `___out' argument markers work also for C++ reference types
--  Recognizes `C_word' and `size_t'
--- The reader supports selective case sensitive/insensitive reading using the 
--  `#cs...' and `#ci...' syntax (as supported in PLT Scheme)
--- `\uXXXX' and `\UXXXXXXXX' escape-sequences for string literals
--- `#\UXXXXXXXX' character literal syntax
--- `\v', `\a' and `\f' escape sequences and `#\delete', `#\esc', `#\alarm', `#\vtab' 
--  and `#\nul' character literals
--- `chicken-setup' supports proxy connections via the `-proxy' option
--- library:
--  (set-dynamic-load-mode! MODE)
--  `(end-of-file)' has been removed (use `#!eof' instead)
--- The alternative continuation API described in Marc Feeley's paper
--  "A better API for first class continuations" is supported natively:
--  (continuation-capture PROC)
--  (continuation-graft K THUNK)
--  (continuation-return K VALUE ...)
--  (continuation? X)
--- `foreign-primitive' and `define-extension' macros
--- tinyclos:
--  (instance-of? X)
--  `define-method' specializes on all arguments and allows DSSSL keyword argument lists
--- eval:
--  (set-dispatch-read-syntax! CHAR PROC)
--- extras:
--  (hash-table-update! HT KEY PROC INIT)
--  (hash-table-exists? HT KEY) 
--  (hash-table-values HT)
--  (hash-table-keys HT)
--  (alist->hash-table ALIST [TEST SIZE])
--  `hash-table->list' has been renamed to `hash-table->alist
--  `hash-table-for-each' takes the arguments in reversed order (the old order is still
--  valid but deprecated)
--  Hash-tables support now user-defined hash functions
--- posix:
--  (file-link OLD NEW)
--  (symbolic-link? FILENAME)
--  (regular-file? FILENAME)
--  errno/exist
