Release Notes: This release adds support for hardware memory transactions. They are much faster than classic software-only ones, but require a CPU with Intel TSX (Transactional Synchronization Extensions) and currently work only on 64-bit SBCL.
Release Notes: This release added SB-TRANSACTION, a library for using Transactional Synchronization Extensions (TSX) i.e. hardware memory transactions provided by the new Intel Core i5 4570, i5 4670, and i7 4770. This library currently requires a 64-bit SBCL compiler. Support for ECL was also added, and memory allocation was reduced to the same level as SBCL on all supported systems. A rare but serious bug affecting read consistency was fixed.
Release Notes: This release adds support for ABCL (Armed Bear Common Lisp). Performance was further improved.
