Steel Bank Common Lisp version 2.6.7
Steel Bank Common Lisp (SBCL) has released version 2.6.7, featuring improvements to documentation, SIMD instruction support for ARM64 and X86-64, and various compiler bug fixes. The update focuses on performance optimizations and better interactive documentation support.
Why it matters
As a foundational tool for Lisp developers, these updates improve the performance and maintainability of high-performance computing applications.
New SBCL versions are usually released at the end of each month: check the Sourceforge File List to see the current version. The new features of all SBCL releases are listed below.
new contrib module: SB-MANUAL contains the SBCL manual in docstrings of
section definitions, which tie together the docstrings of normal Lisp
definitions. The manual can thus be explored interactively in the usual
way (e.g. with Slime's M-.), and it is browsable with the MGL-PAX library
(out of tree). Also, https://fixnum.com/ (similarly unrelated to the SBCL
project) provides alternative renderings of the SBCL manual as heavily
linked PDF and HTML documents as well as Markdown and plain text.
new feature: DOCUMENTATION supports DOC-TYPE DECLARATION.
