-changes relative to sbcl-1.0.48:
+changes relative to sbcl-1.0.51:
+ * enhancement: ASDF has been updated to version 2.017.
+ * enhancement: the --core command line option now accepts binaries with
+ an embedded core.
+ * enhancement: when built with :sb-core-compression, core files (regular
+ or executable) can be compressed with zlib. Use the :COMPRESSION
+ argument to SAVE-LISP-AND-DIE to specify a compression level.
+ * enhancement: --[no-]merge-core-pages determines whether the runtime
+ hints the operating system that identical core pages between SBCL
+ processes should share the same physical memory. Default is to only
+ enable this for compressed cores.
+ * optimization: SLEEP no longer conses.
+ * optimization: *PRINT-PRETTY* no longer slows down printing of strings
+ or bit-vectors when using the standard pretty-print dispatch table.
+ * bug fix: non-function FTYPE declarations no longer cause a compiler-error.
+ (lp#738464)
+ * bug fix: compiler-errors causes by MEMBER types in conjunction with with
+ AREF, CHAR, etc. (lp#826971)
+ * bug fix: compiler-errors causes by integer arguments with composed of
+ multiple ranges to ARRAY-IN-BOUNDS-P. (lp#826970)
+ * bug fix: ,@ and ,. now signal a read-time error for certain non-list
+ expressions. (lp#770184)
+ * bug fix: complex single float literals are correctly aligned when used
+ as arguments of arithmetic operators.
+ * bug fix: on 32-bit platforms, rounding of double floats larger than a
+ fixnum is correct. (reported by Peter Keller)
+ * bug fix: stray FD-HANDLERs are no longer left lying around after unwinds
+ from RUN-PROGRAM. (lp#840190, reported by Dominic Pearson; fix from Max
+ Mikhanosha)
+
+changes in sbcl-1.0.51 relative to sbcl-1.0.50:
+ * minor incompatible change: SB-BSD-SOCKET socket streams no longer
+ participate in SERVE-EVENT by default: pass :SERVE-EVENTS T to
+ MAKE-SOCKET-STREAM if using SERVE-EVENT.
+ * enhancement: added support for socket keepalive timeout intervals
+ and probe counts on Linux.
+ * enhancement: building 32-bit SBCL on Linux/x86-64 now works without a
+ chroot. (Use "SBCL_ARCH=x86 sh make.sh" to build.)
+ * enhancement: added new toplevel options --quit and --non-interactive
+ (lp#822712).
+ * enhancement: the Windows port of SBCL now builds and runs on Wine
+ (thanks to Anton Kovalenko).
+ * enhancement: more, and more correct, SSE instruction definitions on
+ x86-64 (thanks to Alexander Gavrilov).
+ * enhancement: SB-EXT:SPIN-LOOP-HINT assembles to an instruction designed
+ to help the processor execute spin loops, when applicable. Currently
+ implemented for x86 and x86-64.
+ * optimization: unsigned integer divisions by a constant are implemented
+ using multiplication (affects CEILING, FLOOR, TRUNCATE, MOD, and REM.)
+ * optimization: improved type-derivation for LOAD-TIME-VALUE.
+ * bug fix: correct RIP offset calculation in SSE comparison and shuffle
+ instructions. (lp#814688)
+ * bug fix: COERCE to unfinalized extended sequence classes now works.
+ (reported by Jan Moringen; lp#815155)
+ * bug fix: a compiler error during typecheck generation, reported by Eric
+ Marsden. (lp#816564)
+ * bug fix: obsolete instance protocol fires when shared slots are added
+ or removed.
+ * bug fix: fixed-format floating point printing with scaling factors.
+ (lp#811386)
+ * bug fix: using GCC >= 4.6 to build SBCL on x86 no longer breaks
+ backtraces. (lp#818460)
+ * bug fix: better backtraces for interrupted syscall frames on x86.
+ (lp#549673)
+ * bug fix: SSE comparison instructions can be disassembled even when one
+ operand is in memory. (lp#814702)
+ * bug fix: incomplete writes when not using SERVE-EVENTS. (lp#820599)
+ * bug fix: MULTIPLE-VALUE-BIND + VALUES -> LET conversion could lose derived
+ type information associated with the VALUES form.
+ * bug fix: broken warnings/errors for type-errors involving LOAD-TIME-VALUE
+ forms. (lp#823014)
+ * bug fix: OPEN :IF-EXISTS :APPEND now returns correct FILE-POSITION before
+ first write (lp#561642).
+ * bug fix: compiled closures from EVAL could not be DESCRIBEd. (lp#824974)
+ * bug fix: bound propagation involving conversion of large bignums to
+ floats no longer signals a SIMPLE-TYPE-ERROR, reported by Lutz Euler.
+ (lp#819269)
+ * bug fix: &REST to &MORE conversion still works in unsafe call to known
+ functions; reported by Lutz Euler (lp#826459).
+ * bug fix: bogus deadlocks from interrupts and GCs. (lp#807475, regression
+ since 1.0.48)
+
+changes in sbcl-1.0.50 relative to sbcl-1.0.49:
+ * enhancement: errors from FD handlers now provide a restart to remove
+ the offending handler.
+ * enhancement: SB-INTROSPECT:FIND-DEFINITION-SOURCE now works on structure
+ copiers as well.
+ * enhancement: location of user or system initialization file can now easily
+ be customized for saved cores. See: SB-EXT:*USERINIT-PATHNAME-FUNCTION*
+ and SB-EXT:*SYSINIT-PATHNAME-FUNCTION*.
+ * enhancement: SB-EXT:MAKE-THREAD accepts an argument list designator for
+ the thunk, as a keyword argument, :arguments.
+ * enhancement: constraint propagation is simplified (and sped up) when
+ COMPILATION-SPEED > SPEED.
+ * enhancement: SB-ALIEN exports alien type specifiers SIZE-T and OFF-T.
+ * enhancement: debugger understands &MORE arguments better.
+ * optimization: extracting bits of a single-float on x86-64 has been
+ optimized. (lp#555201)
+ * optimization: MAP and MAP-INTO are more efficient for non-simple vectors,
+ when (> SPEED SPACE).
+ * optimization: local call trampolines (x86 and x86-64) are emitted
+ inline.
+ * optimization: implicit value cells for dynamic-extent closed-over bindings
+ on x86 and x86-64 can hold unboxed values as well.
+ * meta-optimization: improved compilation speed, especially for large
+ functions. (lp#792363 and lp#394206)
+ * bug fix: bound derivation for floating point operations is now more
+ careful about rounding possibly closing open bounds. (lp#793771)
+ * bug fix: SB-POSIX:SYSCALL-ERROR's argument is now optional. (accidental
+ backwards incompatible change in 1.0.48.27)
+ * bug fix: occasional debugger errors in when a type-error occured in a
+ function with dynamic-extent &rest list.
+ * bug fix: &optional and &key supplied-p arguments in DEFSTRUCT
+ boa-construtors can be used to initialized structure slots.
+ * bug fix: FMAKUNBOUND removes the MACRO-FUNCTION, should one exist.
+ (lp#795705, regression)
+ * bug fix: DIRECTORY works better on logical pathnames.
+ * bug fix: RUN-PROGRAM no longer fails spuriously when argument strings
+ are of the order of ARRAY-TOTAL-SIZE-LIMIT. (lp#787237)
+ * bug fix: the compiler no longer constant-folds NaNs in
+ MAKE-{SINGLE,DOUBLE}-FLOAT. (lp#486812)
+ * bug fix: FORMAT now handles floating point rounding correct, eg.
+ (format nil "~,1F" 0.01) => "0.0" instead of "0.01" as previously.
+ (lp#308961)
+ * bug fix: style warning during lambda-list introspection of generic
+ functions with both optional and key argments.
+ * bug fix: regalloc doesn't barf on unused TNs due to type-directed constant
+ folding. (lp#729765)
+ * bug fix: Fixed an off-by-one in MAP-ALLOCATED-OBJECTS that might have caused
+ infinite loops.
+
+changes in sbcl-1.0.49 relative to sbcl-1.0.48:
* minor incompatible change: WITH-LOCKED-HASH-TABLE no longer disables
interrupts for its body.
* enhancement: source locations are now available for files loaded as
terminal even if one is available.
** --script can be an argument, causing the script to be loaded from
standard input.
+ * enhancement: MAKE-ALIEN-STRING provides an easy way to transport lisp
+ strings to foreign memory.
+ * enhancement: (SETF GC-LOGFILE) allows logging garbage collections to
+ a file, making it easier to understand heap dynamics.
* optimization: using a &REST argument only in APPLY or VALUES-LIST calls
allows the compiler to automatically elide rest-list allocation so long as
the call sites are in functions that the compiler knows cannot escape.
