sbcl-1.4.11
d7c94c4f · ·changes in sbcl-1.4.11 relative to sbcl-1.4.10: * minor incompatible change: changes to the (internal) assembler on x86 and x86-64 may cause problems to some low-level third-party libraries: ** new macro EA for defining an effective address, without size information; ** an explicit size modifier is now needed for MOVSX and MOVSZ instructions; ** MOVD and MOVQ move a single size of operand by definition. * enhancement: support the latest MinGW (lp#1786731, reported by il71) * enhancement: checks for modifications of constants can now be done in local (FLET/LABELS) functions. * optimization: improved type checking routines for various compound types. * optimization: array bound checks are elided on vectors when the index is known to be less than the length, including LOOP ACROSS. * optimization: the register allocator's use of temporaries is somewhat improved. * optimization: checking widetags involves fewer conditional jumps on x86 and x86-64. * bug fix: fix a number of bugs related to constant improper lists as sequence arguments (lp#1768563, lp#1768568, lp#1768652) -

sbcl-1.4.10
bc7d5266 · ·changes in sbcl-1.4.10 relative to sbcl-1.4.9: * enhancement: added SB-EXT:MAKE-WEAK-VECTOR. * enhancement: constant-modification detection warnings can be generated in the presence of conditional constructs. * optimization: better bounds-checking on x86[-64] and ARM64. * optimization: adding 1 to or subtracting 1 from a fixnum variable does not cons. * bug fixes: fix a number of bugs revealed by random testing (lp#1782826, lp#1779878, lp#1779737) -

sbcl-1.4.9
bd4bcfb4 · ·changes in sbcl-1.4.9 relative to sbcl-1.4.8: * enhancement: SB-COVER instrumentation for x86[-64] has signficantly less overhead. The performance penalty for 64-bit code has been measured at around 30% slower than uninstrumented code as contrasted with slowdowns in excess of 100% previously. * enhancement: tracing a generic function with the :METHODS T option produces output corresponding to each method called under the default :ENCAPSULATE NIL tracing implementation. * bug fix: updated TRACE documentation. (lp#574614 was actually already fixed, but there were other issues.) * bug fix: fixed x86 GC bug causing heap corruption. (lp#1749369) * bug fix: improved compatibility with macOS High Sierra and graphical applications. -

sbcl-1.4.8
6a36da10 · ·changes in sbcl-1.4.8 relative to sbcl-1.4.7: * bug fix: redefinition of method combinations now does the expected thing; generic functions using that method combination have their effective methods lazily recomputed according to the new definition of the method combination. (Reported by Didier Verna at ELS 2018) * bug fix: :arguments argument to the long form of DEFINE-METHOD-COMBINATION is now implemented more correctly, supporting suppliedp variables and &optional defaults. (Reported by Bruno Haible, lp#309084) -

sbcl-1.4.7
11202d65 · ·changes in sbcl-1.4.7 relative to sbcl-1.4.6: * enhancement: better handling of unknown keyword arguments (lp#1750466) * enhancement: namestrings can now be computed for certain pathnames that previously did not have namestrings because of #\. characters in their name and/or type components. * bug fix: compiling a SLEEP call with a float positive infinity argument no longer causes an internal error (lp#1754081) * bug fix: keyword arguments provided to a generic function with EQL-specialized methods are checked more correctly (reported by Syll, lp#1760987) -

sbcl-1.4.6
80568581 · ·changes in sbcl-1.4.6 relative to sbcl-1.4.5: * enhancement: DISASSEMBLE on a symbol naming a macro will disassemble the expander, not the code that traps attempted FUNCALL of the macro. * enhancement: The sb-sprof contrib now provides an experimental interface for accessing collected profiler data. * enhancement: The instruction-level profiling of the sb-prof contrib annotates the disassembler output more efficiently. * optimization: improved dynamic-extent handling of nested variables. -
