4.3.5

- on Windows loading of code compiled with [non-]GUI runtime libraries
  will fail and produce an error message when the loading executable
  is linked with a different runtime system
- on Windows, GUI libraries were not correctly linked by `csc'
- unit posix: added setter for `file-modification-time'

4.3.4

- the banner shows the branchname of the build, unless it's "master"
- the `-no-install' option to `chicken-install' is ignored when
  building/installing dependencies
- `chicken-uninstall' takes a glob instead of a regular expression as
  argument
- fixed bug that caused the `unboxing' optimization to generate incorrect
  C code
- the rename and compare functions for low-level macro-definitions 
  accept now arbitrary s-expressions and renames/compares them recursively
- `number->string' handles negative-numbers with bases different from 10
  correctly (thanks to Peter Danenberg)
- removed deprecated `setup-install-flag' and `setup-verbose-flag' from
  the `setup-api' module

4.3.3

- various mingw Makefile fixes (Thanks to Jim Ursetto)
- added new option `-repository' to `chicken-install' (Thanks to Christian
  Kellermann)
- removed `chicken-setup' stub program
- fix to `csc' to use the correct library when fixing dynamic load paths
  (Thanks to Derrell Piper)
- removed html documentation from distribution (the wiki manual will
  now be installed)
- fixed bug in `reexport' which caused syntax not to be correctly
  reexported
- previous assignments to a toplevel variable that are separated by
  side effect free expressions are removed
- fixed windows version of `find-files' (thanks to Jim Ursetto)
- documentation for extensions is not installed automatically by
  `chicken-install' anymore

4.3.2

- changed binary version from "4" to "5", because the new runtime
  libraries are not binary-compatible with previous releases; this
  means all eggs have to be reinstalled and existing programs be
  recompiled!
- added unboxing pass to compiler which results in partially dramatical
  performance improvements for unsafe floating-point-intensive code;
  unboxing is enabled on optimization levels 4 and 5
- removed rest-argument-vector optimization as it could conflict
  with inlining (thanks to Sven Hartrumpf)
- added `slatex' to tests
- renamed `pointer-offset' to `pointer+' and deprecated `pointer-offset'
- toplevel assignments that have no other side-effects can be eliminated
  if it can be shown that the value is not used (the compiler will
  generate a warning in this case)
- removed deprecated `-quiet' option in `chicken' program
- removed deprecated `run-time-macros' declaration
- removed deprecated `-v2' and `-v3' options in `csc' program
- removed deprecated `list-of' function (it is exclusively available
  as `list-of?' now)
- removed deprecated `stat-...' functions in posix library unit
- removed deprecated `for-each-line' and `for-each-argv-line' procedures
  in utils library unit

- fixes in types.db by Jim Ursetto
- `move-memory!' catches negative offsets now (Thanks to Jim Ursetto)
- deprecated `define-compiled-syntax'
- added new floating-point primitives `fpsin', `fpcos', `fptan',
  `fpasin', `fpacos', `fpatan', `fpatan2', `fpexp', `fplog', 
  `fpexpt' and `fpsqrt'
- heavy cleanup of floating math functions which gives much better performance
- calling `assert' with a single argument shows the tested expression
  on failure

4.3.0

- removed tracing facility and apply-hook (see the "trace" egg
  for a replacement for tracing and breakpoints)
- chicken-install(1): renamed `-host-extension' option to `-host'
- added support for a make(1) configuration file ("config.make")
- `chicken-install' now allows specifiying a proxy for retrieving
  extensions over HTTP (thanks to Nicolas Pelletier)
- fixed bug in `cond-expand' that incorrectly renamed feature-identifiers
  if the form was the product of a syntax expansion (reported by Thomas
  Bushnell)
- import-libraries are only generated by the compiler if they don't exist
  yet and if the content has actually changed (this simplifies makefile-
  rules in some cases)
- it is now possible to pass a config-file to `make(1)' instead of specifying
  all build-options as variables on the command-line (see README)
- removed compiler options for "benchmark-mode" and replaced them with a
  new optimization level (5) (note that `-O5' does not imply fixnum mode
  anymore)
- `hen.el' and `scheme-complete.el' are not bundled with the core system
  anymore - `hen.el' is currently not maintained, and `scheme-complete.el'
  has its own release cycle; both files are available, see
  http://chicken.wiki.br/emacs
- removed meaningless benchmark suite and cleaned up
- added optional argument to `grep' that allows applying a function
  to each matched item (contributed by Tony Sidaway)
- added extension-property `import-only', which makes it possible to
  create extensions that have no runtime part
- the argument to `seconds->string', `seconds->utc-time' and 
  `seconds->local-time' is now optional and defaults to the value
  of `(current-seconds)' (suggested by Mario Goulart)
- removed read-syntax for `syntax' form
- fixed bug in `get-condition-property'
- fixed bug in windows version of `process-execute'
- TCP timeouts throw exception of kind `timeout' to allow
  distinguishing between timeouts and other errors
- removed some internal functions that manipulate environments
- fixed bugs in `standard-extension' (`setup-api' module) and added keyword 
  arguments for building static extensions and adding custom properties
- when cross-compiling, `chicken-install(1)' doesn't pass `-setup-mode'
  (the host tools should not attempt to load target binaries)
- `installation-prefix' in the `setup-api' module was not always correctly
  set
- the `-force' option in `chicken-install(1)' overrides the CHICKEN version
  check
- disabled e-mail feature in `chicken-bug(1)', since it doesn't work
  anyway, in the moment
- fixed bug in `reexport' that made it impossible to reexport core library
  definitions
- fix in optimizer that sometimes caused C functions for inlined
  procedures to be emitted multiple times (Thanks to Joerg Wittenberger)
- documented `define-compiler-syntax' and `let-compiler-syntax'
- printer for hash-tables shows current number of stores items
- when upgrading during installation of a dependency `chicken-install'
  shows the version to upgrade to (Thanks to Christian Kellermann)
- Updated scheme-complete (Thanks to Alex Shinn)
- fix for pathnames with whitespace in 'runtests.sh' on Windows
- fix for 'normalize-pathname' with absolute pathname argument
- added 'decompose-directory' to unit files

  so tz-name constant
- deprecated 'make-pathname' separator argument

4.2.0

- added compiler option `-emit-all-import-libraries'
- added `reexport'
- added compiler and interpreter option `-setup-mode'

- `for-each-line' and `for-each-argv-line' have been deprecated
- chicken-install tries alternative servers if server responds with error
- fixed load bug (ticket #72)
- new library procedure `get-condition-property'
- many mingw build fixes (thanks tp Fadi Moukayed)
- setup-api: deprecated `cross-chicken' (use `cond-expand' or
  `feature?' instead)
- added topological-sort to data-structures unit; chicken-install
  sorts dependencies before installing them
- "-optimize-level 2" enables inlining by default
- disable executable stack in assembly code modules (patch by
  Zbigniew, reported by Marijn Schouten)
- csc now always exits with a status code of 1 on errors (patch by Zbigniew)

4.1.0

- The new parameter "parantheses-synonyms" and the command-line
  option "-no-parantheses-synonyms" allow disabling list-like behaviour
  of "{ ... }" and "[ ... ]" tokens

  this tool (which has been replaced in 4.0.0 with "chicken-install")
- Changed "setup-install-flag" and "setup-verbose-flag" to
  "setup-install-mode" and "setup-verbose-mode" in "setup-api" module,
  the old names are still available but deprecated
- Posix unit:
  added "socket?", "block-device?" and "character-device?", deprecated
  redundant "stat-..." procedures
- Added "directory-exists?"
- "(for-each (lambda ...) X)" is compiled as a loop
- The argument-count check for format-strings for "[sf]printf" with a constant 
  string argument is done at compile-time
