Steel Bank Common Lisp is a development environment for Common Lisp, with excellent support for the ANSI standard: garbage collection, lexical closures, powerful macros, strong dynamic typing, incremental compilation, and the famous Common Lisp Object System (multimethods and all). It also includes many extensions, such as native threads, socket support, a statistical profiler, programmable streams, and more. These are all available through an integrated, interactive native compiler which feels like an interpreter. SBCL is unique in being a multiplatform native compiler which bootstraps itself completely from source, using a C compiler and any other ANSI Common Lisp implementation.

Changes: This release adds two new ports for OpenBSD and Solaris on x86-64, one improvement, and three bugfixes.


Changes: Bugfixes, enhancements, and optimizations. Some incompatible changes were introduced in this release.


Changes: SAVE-LISP-AND-DIE can now save current values of --dynamic-space-size and --control-stack-size in the executable core, causing it to skip normal runtime option processing. This allows saved executables to fully customize their own commandline processing. A new commandline argument --script has been added, which supports shebang lines.

Unfortunately, the Trove categories aren't quite as flexible as we want.
