Release Notes: Single-stepping of code is now supported, provided the code is compiled with the appropriate DEBUG settings. It is now possible to save a core image that has external code linked in it on the x86 and SPARC architectures. The compiler now supports stack allocation of lists declared DYNAMIC-EXTENT on x86.
Release Notes: This release included many enhancements to the user manual, including for the SB-BSD-SOCKETS, SB-GRAY, SB-SIMPLE-STREAMS, SB-PROFILE, and ASDF modules. Backtraces from the debugger should now be much more useful. The ALIEN foreign function interface now supports mutually referent structures. Many bugfixes were incorporated and optimizations were added for large number GCD and modular arithmetic shifts.
Release Notes: This version contains a major new feature, SB-PACKAGE-LOCKS. Package locks prevent users from accidentally binding or redefining symbols inside locked packages (typically the COMMON-LISP package, and implementation packages). Also, the SB-SPROF statistical profiler now works on most platforms (it does not work on Alpha, however). Several bugfixes, including thread stability improvements, are also a part of this release.
Release Notes: This release features a new profiler, a number of bugfixes, and user hooks for customizing the ed function's behavior.
Release Notes: The compiler is now 20% faster on non-x86 platforms. Support for the SLIME Lisp/Emacs IDE was enhanced. The new sb-ext:muffle-conditions declaration is available to turn down the level of compiler notes. A variety of bugs have been fixed, many for ANSI compliance.
Release Notes: Focuses for this release include bugfixes and performance improvements, particularly improving the performance of building SBCL itself.
Release Notes: This version includes many bugfixes, optimizations, and enhancements. Specific enhancements for this release include merging of the Darwin build-fix patch, a fix to RUN-PROGRAM on PowerPC, garbage collection changes, inlined SEARCH on sequences, and many bugfixes and compliance fixes.
Release Notes: A framework for allowing user-contributed packages to be managed alongside the system and third-party packages has been implemented. This release includes the ASDF defsystem utility, a sockets implementation, a custom read-eval-print loop, and some efficient 32-bit numerical code. Many bugs have been fixed, and optimizations have been made to the object system internals.
Release Notes: Bugfixes and optimization improvements were made.
