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 + 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). (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. (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.
