Dear CHICKEN users, We are pleased to announce the immediate availability of CHICKEN 4.11.0 at the following URL: https://code.call-cc.org/releases/4.11.0/chicken-4.11.0.tar.gz
This tarball has the following SHA256 checksum: e3dc2b8f95b6a3cd59c85b5bb6bdb2bd9cefc45b5d536a20cad74e3c63f4ad89 This release introduces several large changes, the one with the most impact being a completely new calling convention for compiled CPS procedures in C code. Instead of expecting "regular" C arguments, the compiled C functions now accept a so-called "argvector" which holds the arguments. This should greatly improve the portability of CHICKEN programs, because it relies less on ill-specified parts of C. It also removes the assembly code required for manyargs, so that the limitation of 128 arguments for platforms without an "apply hack" has finally been removed. On the tooling front we've also added two new features: a statistical profiler for analysing performance, and a graphical debugger called "feathers", which allows you to inspect your Scheme programs over the network. These have both been documented in the manual. The debugger has its own chapter at https://wiki.call-cc.org/man/4/Debugging and the profiler's new -:p runtime option is documented at https://wiki.call-cc.org/man/4/Using%20the%20compiler#runtime-options As usual, many bugs have been fixed with this release, including several bugs that would cause programs to crash. All in all, this new release should be much more robust and reliable. For the complete list of changes since 4.10.0, see the NEWS file: https://code.call-cc.org/releases/4.11.0/NEWS After this release, the core team has decided to focus its efforts on CHICKEN 5. The 4.x series is still officially supported and will continue to receive bugfixes for critical bugs. If enough bugs have been fixed, there may be a 4.12 release, but new feature development is going to be exclusive to the 5 branch. Regards, The CHICKEN Team
