Chicken

Multiple fixes and improvements to the compiler scrutinizer and optimizer have been made. Extensive fixes in the foreign function interface and the runtime system have been made. Many deprecated procedures in the core libraries have been removed. The build system makefiles have been cleaned up heavily, and several bug fixes have been made for BSD and mingw/msys platforms.

Some compiler optimizations have been significantly improved. Several built-in procedures and the allocation procedures for lists, vectors, and structures generate faster code. Units srfi-4 and srfi-18 have been heavily cleaned up and optimized. Several bugs have been fixed in the thread scheduler. chicken-install has been extended, and its cross compilation support has been significantly upgraded. The build system now supports more platforms and compilers. The various infrastructure scripts have been overhauled to reflect the structure of the new Web site infrastructure.

A number of fixes have been made in the regex and posix units, in the command-line option handling of csc and chicken-install, and in the build process for Windows and Mac OS X. The performance of the syntax expander has been improved and hard-coded special forms have been replaced with proper syntax definitions that expand into internal forms. A number of other small fixes in the library functions and chicken-install have been made.

The Chicken compiler and build tools have been extended to build fully self-contained application bundles and Mac OS X GUI applications. The compiler has been extended with an unboxing pass and the math functions have been heavily cleaned up, resulting in significant performance improvements for floating-point-intensive code in unsafe mode. The chicken-install program can now install extensions from private repositories and is capable of selecting between development and release versions. Many deprecated functions and the HTML documenation have been removed.

The Chicken trace facility has been removed from core and a replacement has been provided in the extension repository. The benchmark suite has been removed and Emacs support files have been removed from the core distribution. Multiple bugfixes and improvements were made in the compiler, the module system, and chicken-install.
