+ generic function call.
+ * bug fix: correct restart text for the continuable error in MAKE-PACKAGE.
+ * bug fix: a rare case of startup-time page table corruption.

+ (lp#535658)
+ * bug fix: SB-CLTL2:DECLARATION-INFORMATION did not take
+ SB-EXT:RESTRICT-COMPILER-POLICY into account. (lp#313337)

+ * bug fix: SIGNAL SB-SYS:INTERACTIVE-INTERRUPT before entering the debugger
+ due to it, so that handlers can run.
+ * bug fix: reparsing undefined types if they have become defined since
+ parsing. (lp#309128)

+ * bug fix: WHO-CALLS information for source-transformed and compiler-macro
+ expanded calls (lp#542174)
+ * bug fix: more accurate WHO-MACROEXPANDS information; point into rather
+ than just at toplevel form.
+
+changes in sbcl-1.0.36 relative to sbcl-1.0.35:
+ * new feature: SB-EXT:TYPEXPAND-1, SB-EXT:TYPEXPAND, and
+ SB-EXT:TYPEXPAND-ALL behave exactly like their MACROEXPAND counterparts
+ but work on type specifiers.
+ * new feature: SB-EXT:DEFINED-TYPE-NAME-P returns whether a symbol is known
+ to name a type specifier.
+ * new feature: SB-EXT:VALID-TYPE-SPECIFIER-P returns whether a given type
+ specifier is valid where "valid" basically means "would be accepted as
+ second argument of TYPEP".
+ * new feature: SB-INTROSPECT:FUNCTION-TYPE takes a function-designator and
+ returns the function's declared, or derived FTYPE.
+ * new feature: SB-POSIX now supports accessing the d_ino member of
+ dirent structures. (Thanks to Philipp Marek and Pierre THEIRRY)
+ * new feature: The function SB-EXT:SEED-RANDOM-STATE has been added to
+ provide for seeding a RANDOM-STATE object with user-provided data or
+ from the operating system's PRNG. Also, (MAKE-RANDOM-STATE T) will
+ attempt to initialize the returned state from the operating system's
+ PRNG where possible. (Thanks to Fare Rideau; launchpad bug lp#310116)
+ * bug fix: Fix SB-SIMPLE-STREAMS:READ-VECTOR to correctly set the
+ FILE-POSITION of the stream being read from. (launchpad bug lp#491087)

+ Bruce O'Neel.
+ * bug fix: SB-THREAD:CONDITION-WAIT sometimes signaled a deadline twice
+ in a row even though a handler defered the deadline long into the
+ future. (lp#512914)
+ * bug fix: A deadline handler was run without interrupts enabled for a
+ deadline signaled within SB-THREAD:CONDITION-WAIT. That could result
+ in infinitely spinning, non-killable threads.
+ * bug fix: Backtrace from internal-errors on x86-64 os x was truncated
+ before reaching the erring stack frame.

+ * optimization: ROUND with a single single-float or double-float argument
+ is properly inlined when possible.
+ * optimization: Slightly better code is generated for integer<->float
+ conversions and for single-float<->double-float conversions on x86-64.

+ code for 32-bit and 64-bit rotations on x86-64.
+ * bug fix: The install script changes the ownership of directories as well
+ as files for contrib modules using asdf. (thanks to Eugene Ossintsev;
+ launchpad bug lp#508485)
+ * bug fix: TRUNCATE with a single single-float or double-float argument is
+ properly inlined when possible. (launchpad bug lp#489388)
+ * bug fix: Passing a rotation count of zero to SB-ROTATE-BYTE:ROTATE-BYTE
+ no longer causes a compiler error on x86 and ppc.
+ * bug fix: GET-MACRO-CHARACTER bogusly computed its second return value
+ always relative to *READTABLE* rather than the passed argument.
+
+changes in sbcl-1.0.34 relative to sbcl-1.0.33:
+ * minor incompatible change: threading support is now enabled by default
+ on x86[-64] Linux.
+ * enhancement: SB-INTROSPECT:DEFTYPE-LAMBDA-LIST now also works on most
+ builtin types.
+ * enhancement: Errors during compile-time-too processing (i.e. EVAL-WHEN)
+ are now caught and reported just like errors during macroexpansion.
+ * enhancement: SB-POSIX now provides access to tcdrain(), tcflow(),
+ tcflush(), tcgetsid(), and tcsendbreak(). (thanks to Jerry James)
+ * enhancement: ASDF systems can now depends on SB-QUEUE.
+ * fixes and improvements related to Unicode and external formats:
+ ** bug fix: error handling and restart usage in the ucs-2 external format
+ has been improved.
+ ** there is now an implementation of the ucs-4 external format.
+ ** the utf-16 and utf-32 external formats are supported.
+ * bug fix: SB-POSIX wrapper for putenv no longer tries to put lisp strings
+ in the environment. setenv() and unsetenv() are also provided. (reported by
+ Fare Rideau; launchpad bug lp#460455)
+ * bug fix: LOAD of both .fasl and .FASL type files now forces fasl-style
+ loading. This ensures sensible errors for .FASL files from other
+ implementations on case-insensitive filesystems. (reported by Willem
+ Broekema; launchpad bug lp#489417)
+ * bug fix: #p"\\\\" can now be read without error on Win32. (reported by
+ Willem Broekema; launchpad bug lp#489698).
+ * bug fix: some minor code rearrangements to reenable warning-free building
+ from CMUCL (reported by xme@gmx.net; launchpad bug lp#491104)
+ * bug fix: PRINT-OBJECT for clos instances respects the right margin when
+ pretty printing
+ * bug fix: FIND-PACKAGE & DEFPACKAGE were not thread safe. (reported by
+ Attila Lendvai)
+
+changes in sbcl-1.0.33 relative to sbcl-1.0.32:
+ * new port: support added for x86-64 NetBSD. (thanks to Aymeric Vincent)
* improvement: support O_LARGEFILE access to files larger than 2GB on
- x86-64/linux. (thanks to Daniel Janus; launchpad bug #453080)
+ x86-64/linux. (thanks to Daniel Janus; launchpad bug lp#453080)
* new feature: SB-INTROSPECT:WHO-SPECIALIZES-DIRECTLY to get a list of
definitions for methods specializing on the passed class itself.
* new feature: SB-INTROSPECT:WHO-SPECIALIZES-GENERALLY to get a list of
definitions for methods specializing on the passed class itself, or on
subclasses of it.
+ * new build flag: :sb-xref-for-internals; SBCL will collect xref information
+ about itself during the build (e.g. for M-? in Slime), if this flag is
+ enabled in customize-target-features.lisp. This will increase the core
+ size by about 5-6mb, though, so it's mostly interesting to SBCL
+ developers.
+ * new feature: various GENCGC tuning parameters have been experimentally
+ documented and exported from SB-EXT. See documentation for details.
* fixes and improvements related to Unicode and external formats:
** the Unicode character database has been upgraded to the
Unicode 5.2 standard, giving names and properties to a number of new
(:<encoding> :replacement <character>) as an external format which will
automatically substitute <character> on encoding or decoding errors for
streams and for STRING-TO-OCTETS and its inverse. (launchpad bug
- #317072)
+ lp#317072)
** improvement: the file streams underlying the standard streams (such as
*STANDARD-INPUT*, *TERMINAL-IO*) are opened with an external format
which uses the replacement mechanism to handle encoding errors,
between #xd800 and #xdfff).
** fix a typo preventing conversion of strings into octet vectors
in the latin-2 encoding. (reported by Attila Lendvai; launchpad bug
- #471689)
+ lp#471689)
** fix a bug in the octet multibyte handling of decoding errors and the
- USE-VALUE restart. (launchpad bug #314939)
+ USE-VALUE restart. (launchpad bug lp#314939)
** fix the bug underlying the expected failure in the FORCE-END-OF-FILE
restart on fd-stream decoding errors.
** fix a bug in the ATTEMPT-RESYNC fd-stream decoding restart when the
streams after an UNREAD-CHAR.
* enhancement: SB-INTROSPECT:ALLOCATION-INFORMATION also reports if the
object is allocated in a boxed region of dynamic space.
+ * enhancement: SB-POSIX:FORK now signals an error if an attempt to
+ fork with multiple Lisp threads running is made, instead of going
+ ahead with unpredictable consequences. (reported by Leslie Polzer)
* bug fix: uses of slot accessors on specialized method parameters within
the bodies of SLOT-VALUE-USING-CLASS methods no longer triggers a type
error while finalizing the class. This fix may cause classes with slot
accessors to be finalized later than previously. (reported by Lars Rune
- Nøstdal; launchpad bug #473699)
+ Nøstdal; launchpad bug lp#473699)
* bug fix: restore buildability on the MIPS platform. (regression from
1.0.30.38, reported by Samium Gromoff)
* bug fix: inspecting closures is less likely to fail with a type error.
* bug fix: no timer starvation when setting the system clock back.
- (launchpad bug #460283)
+ (launchpad bug lp#460283)
* bug fix: WITH-STANDARD-IO-SYNTAX now binds *PRINT-PPRINT-DISPATCH* to the
standard pprint dispatch table as specified by CLHS.
* bug fix: give CLISP a hint about a type declaration to enable it to build
the cross-compiler without warnings. (thanks to Josh Elasser; launchpad
- bug #396597)
+ bug lp#396597)
* bug fix: correctly dump literal objects in defaulting forms of arglists.
- (reported by Attila Lendvai; launchpad bug #310132)
+ (reported by Attila Lendvai; launchpad bug lp#310132)
+ * bug fix: distinguish in type specifiers between arrays that might be
+ complex and arrays that are definitely complex. (launchpad bug lp#309129)
+ * bug fix: SUBTYPEP knows that the SYMBOL type is not SUBTYPEP the KEYWORD
+ type. (reported by Levente Mészáros; launchpad bug lp#485972)
+ * bug fix: setting the value of a symbol-macro within a method in the
+ presence of type declarations works properly again. (reported by Iban
+ Hatchondo; launchpad bug lp#485019)
