-changes relative to sbcl-1.0.57:
+changes relative to sbcl-1.1.2:
+ * bug fix: fasls are now once again directly executable (on platforms
+ supporting shebang lines, with a suitably-installed sbcl).
+
+changes in sbcl-1.1.2 relative to sbcl-1.1.1:
+ * notice: System requirements for SBCL on Microsoft Windows: Windows NT 5.1
+ or newer (Windows XP, Server 2003) is required. Support for Windows 2000
+ (NT 5.0) is no longer being maintained.
+ * notice: Starting with this version, SBCL on Windows no longer supports
+ building with disabled thread support.
+ * enhancement: frlocks have been added to SB-CONCURRENCY contrib module.
+ * enhancement: New feature sb-dynamic-core allows the runtime to be
+ rebuilt or relocated without requiring changes to the core file on
+ all linkage table platforms. Required on Windows. (Thanks to Anton
+ Kovalenko.)
+ * enhancement: Console I/O streams use UCS-2. (Thanks to Anton Kovalenko.)
+ * enhancement: I/O on Windows unnamed pipes is interruptible
+ asynchronously using interrupt-thread, timers when running on Windows NT
+ version 6.1 or newer (Windows 7, Server 2008 R2). (Thanks to Anton
+ Kovalenko.)
+ * enhancement: Support for the experimental safepoint-based stop-the-world
+ protocol on the PowerPC platform.
+ * bug fix: Non-blocking reads from the Windows console were not necessarily
+ non-blocking. Thanks to Anton Kovalenko. (lp#308923)
+ * bug fix: stability of threads on Windows has been improved upon through
+ an updated stop-the-world protocol (thanks to Anton Kovalenko).
+
+changes in sbcl-1.1.1 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
* 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
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).
