+changes relative to sbcl-1.1.0:
+ * enhancement: WITH-COMPILATION-UNIT no longer grabs the world-lock.
+ (COMPILE and COMPILE-FILE still do.)
+ * optimization: the SPARC backend now supports the precise generational
+ (GENCGC) garbage collection. Enabled by default on Solaris/SPARC and
+ Linux/SPARC. Thanks to Raymond Toy (via CMUCL).
+ * enhancement: add experimental support for the SB-THREAD feature and the
+ timer facility on Windows. Thanks to Dmitry Kalyanov and Anton Kovalenko.
+ Threads are enabled by default, and this version of SBCL is considered
+ to be the last and final release to officially support building with
+ threads disabled.
+ * optimization: The compiler no longer rotates loops in some cases where
+ this transformation actually lead to worse code being generated.
+ * bug fix: SB-CLTL2:MACROEXPAND-ALL correctly handles shadowing of
+ symbol-macros by lexical bindings.
+ * bug fix: stack allocation was prevented by high DEBUG declaration in
+ several cases.
+ * bug fix: SB-EXT:GC-LOGFILE signaled an error when no logfile was set.
+ (thanks to SANO Masatoshi)
+ * bug fix: PARSE-NATIVE-NAMESTRING performed non-native parsing when
+ :JUNK-ALLOWED was true.
+ * bug fix: type derivation inferred overly conservative types for
+ unions of array types. (lp#1050768)
+
+changes in sbcl-1.1.0 relative to sbcl-1.0.58:
+ * enhancement: New variable, sb-ext:*disassemble-annotate* for controlling
+ source annotation of DISASSEMBLE output. Defaults to T.
+ * enhancement: TIMEOUT arguments added to WITH-MUTEX and WITH-RECURSIVE-LOCK, and
+ WAIT-P argument added to WITH-RECURSIVE-LOCK.
+ * enhancement: SB-EXT:ATOMIC-PUSH and SB-EXT:ATOMIC-POP allow atomic operations
+ on list heads.
+ * enhancement: Optional features (not enabled by default) allow the
+ use of signals for inter-thread synchronization to be reduced on certain
+ supported platforms (currently Linux, Solaris, and FreeBSD on x86 and
+ x86-64). Set (and :sb-thread :sb-safepoint :sb-thruption :sb-wtimer)
+ to test these experimental features. Known remaining bugs include minor
+ thread safety issues, less timely freeing of memory by GC, and certain
+ (not yet optimally low) runtime overhead. Thanks to Anton Kovalenko.
+ * optimization: CL:SORT and CL:STABLE-SORT of lists are faster and use fewer
+ comparisons, particularly on almost-sorted inputs.
+ * bug fix: Reading floats with large exponents no longer takes too much time
+ before reporting that the exponent is too large.
+ * bug fix: SB-BSD-SOCKETS:SOCKET-RECEIVE with a UDP socket now works
+ correctly when the received datagram is larger than the provided buffer.
+ (lp#1023438, thanks to Robert Uhl)
+ * bug fix: SB-EXT:GET-CAS-EXPANSION returned a bogus read-form when given
+ a SYMBOL-VALUE form with a constant symbol argument.
+ * bug fix: SB-EXT:GET-CAS-EXPANSION signaled an error when a macro expanding
+ into a DEFCAS defined place was used as the place.
+ * bug fix: FIND and POSITION signaled a type-error when non-bits where looked
+ for from bit-vectors.
+ * bug fix: a race condition around thread creation could (in SBCL 1.0.57)
+ lead to internal errors or crashes (lp#1058799).
+ * documentation: a section on random number generation has been added to the
+ manual. (lp#656839)
+
+changes in sbcl-1.0.58 relative to sbcl-1.0.57:
* enhancement: implicit generic function warnings now specify the package
in which the new generic function is being created.
* enhancement: SB-EXT:ATOMIC-UPDATE makes it easy to perform non-destructive
updates of CAS-able places (similar to Clojure's swap!).
* enhancement: run-program no longer decodes and re-encodes environment when
:environment argument is not provided. (lp#985904)
+ * enhancement: errors during compiler-macro expansion no longer cause
+ runtime errors, only a compile-time warning, otherwise behaving as if
+ the compiler macro had declined to expand.
* optimization: On x86-64, code alignment of block headers is done with
multi-byte NOPs now instead of repetitions of the single-byte NOP.
* optimization: MAP-INTO is substantially faster when the target sequence is
- of unknown type; mapping into lists is no longer O(N^2). (thanks to James
- M. Lawrence)
+ of unknown type; mapping into lists is no longer O(N^2). (lp#1001043,
+ thanks to James M. Lawrence)
* optimization: the compiler no longer heap-conses to check exits in cases
where the exit function is dynamic extent, or when it can prove the exit
- function cannot escape.
+ function cannot escape. (lp#1002534)
* optimization: SB-SEQUENCE:DOSEQUENCE is faster on vectors of unknown
element type, and vectors that aren't SIMPLE-ARRAYs.
+ * optimization: CL:SORT and CL:STABLE-SORT are more efficient in execution
+ speed (around 1/3 the time in some cases), and a little better in terms of
+ comparison calls. (Thanks to Takeru Ohta)
+ * bug fix: On SPARC, a limitation on the number of code constants emittable
+ by the compiler has been lifted, allowing certain long functions to
+ compiled and assembled which had previously been unsupported; fixes
+ cl-bench on this ISA (lp#1008996).
* bug fix: potential for infinite recursion during compilation of CLOS slot
typechecks when dependency graph had loops. (lp#1001799)
* bug fix: error forms reported with some program-errors were not escaped
method combinations. (lp#936513)
* bug fix: run-program no longer unconditionally uses /tmp/ for temporary
files. (lp#968837).
+ * bug fix: restore build on solaris/sparc. (lp#1008506)
+ * bug fix: an issue with LDB in the PowerPC backend has been resolved;
+ this fixes an issue found with cl-postgres (thanks to Tomas Hlavaty).
+ * bug fix: compiler-macro lambda-lists specifying non-keyword symbols
+ as keyword arguments no longer accidentally match unevaluated symbols
+ against them.
+ * bug fix: FORMAT used to loop infinitely in some cases when a COLINC
+ parameter was zero, now it signals an error. (lp#905817, fixed since
+ 1.0.56.19)
+ * bug fix: run-program with :pty t no longer makes the pty as the process's
+ controling terminal.
+ * bug fix: spawning threads on OS X 10.8 no longer crashes the process
+ (lp#1012811).
