See manual for details. + * new feature: SB-EXT:MAP-DIRECTORY provides a powerful interface for + directory traversal: it is the backend used by SBCL for CL:DIRECTORY. + * enhancement: easier to use restarts for resolving name-conflicts + resulting from IMPORT, EXPORT, or USE-PACKAGE. + * enhancement: variant DEFPACKAGE forms now signal a full error with + restarts provided for resolving the situation. (lp#891351) + * enhancement: by setting SB-EXT:*ON-PACKAGE-VARIANCE* appropriately variant + DEFPACKAGE forms can now signal a full error with restarts provided for + resolving the situation. See manual for details. (lp#891351) + * enhancement: make-random-state now uses CryptGenRandom as a seed on Windows. + (Thanks to Anton Kovalenko.) (lp#1102748) + * enhancement: backtrace improvements + ** secondary CLOS dispatch functions have better debug names (lp#503081) + ** easier to read method names in backtraces. See + SB-DEBUG:*METHOD-FRAME-STYLE*. + ** SB-DEBUG:PRINT-BACKTRACE and SB-DEBUG:LIST-BACKTRACE are available as + forwards-compatible replacements for SB-DEBUG:BACKTRACE and + SB-DEBUG:BACKTRACE-AS-LIST. + ** SB-DEBUG:*SHOW-ENTRY-POINT-DETAILS** has been deprecated, as the same + information is available in less intrusive form as frame annotations. + * bug fix: deleting a package removes it from implementation-package + lists of other packages. + +changes in sbcl-1.1.4 relative to sbcl-1.1.3: + * optimization: LOOP expressions using "of-type character" have slightly + more efficient expansions. + * bug fix: very long (or infinite) constant lists in DOLIST do not result + in very long compile times or heap exhaustion anymore. (lp#1095488) + * bug fix: `#3(1) is read as #(1 1 1), not as #(1). (lp#1095918) + * bug fix: adjust-array ignored :initial-element for simple-vectors. + (lp#1096359) + * bug fix: optimizations to MAKE-INSTANCE with literal list initargs no + longer cause infinite loops (on circular data) or violate eqlity + constraints. (lp#1099708) + * bug fix: FIRST was not being open coded. (regression from 1.1.0) + +changes in sbcl-1.1.3 relative to sbcl-1.1.2: + * enhancement: warnings about bad locale settings, LANG, LC_CTYPE, etc. + (lp#727625) + * enhancement: support for C-c to interrupt the foreground thread + on Windows. (Thanks to Anton Kovalenko.) + * enhancement: STDCALL alien callbacks. (Thanks to Anton Kovalenko.) + * enhancement: Safepoint builds on POSIX platforms can now optionally be + built without pseudo-atomic sequences and their run-time overhead. + * enhancement: Threads created outside of Lisp can enter Lisp through + alien callbacks and appear as Lisp threads for the duration of that + function invocation. On safepoint builds only. + * enhancement: Miscellaneous improvements to namestrings and underlying + calls to OS functions for file system access on Windows. (Thanks to + Anton Kovalenko.) + * enhancement: The MSI installer support for Windows now uses Windows + Installer XML at least version 3.5 and includes various usability + improvements. (Thanks to Dmitry Kalyanov and Anton Kovalenko.) + * enhancement: The sb-bsd-sockets contrib now supports non-blocking-mode + on Windows. (Thanks to Anton Kovalenko.) + * enhancement: The Windows backend now supports the x86-64 platform. + (Thanks to Anton Kovalenko.) + * bug fix: fasls are now once again directly executable (on platforms + supporting shebang lines, with a suitably-installed sbcl). + * bug fix: make.sh --help no longer runs clean.sh. (lp#937001) + * bug fix: Fix CAS access to slots of direct instances of structure classes + in the presence of subclasses sharing the same conc-name. + * bug fix: Logical pathname namestrings on Windows have been changed to + be lower-case, to minimize differences between POSIX and Windows. + +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.
