+changes in sbcl-1.0.28 relative to 1.0.27:
+ * bug fix: timers could go off in the wrong order, be delayed indefinitely
+ (thanks to Ole Arndt for the patch)
+ * bug fix: RESTART-FRAME and RETURN-FROM-FRAME stack corruption
+ * bug fix: the discriminating function for PRINT-OBJECT no longer preserves
+ potentially-invalid effective methods in its cache.
+
+changes in sbcl-1.0.27 relative to 1.0.26:
+ * new port: support added for x86-64 OpenBSD. (thanks to Josh Elsasser)
+ * new port: support added for x86-64 Solaris. (thanks to Alex Viskovatoff)
+ * improvement: the system either recovers from stack exhaustion or dies
+ properly as opposed to leaving the user uncertain of whether the handler
+ trampled on some random memory next to the stack or having to rely on
+ --lose-on-corruption (which is still a good idea to use in production
+ because stack exhaustion can happen in signal handlers which will likely
+ lead to hangs.)
+ * bug fix: fix gc related interrupt handling bug on ppc (regression from
+ 1.0.25.37, reported by Harald Hanche-Olsen)
+ * bug fix: work around signal delivery bug in darwin (regression from
+ 1.0.25.44, reported by Sidney Markowitz)
+ * bug fix: fix ERROR leaking memory (reported by David Thompson)
+
+changes in sbcl-1.0.26 relative to 1.0.25:
+ * incompatible change: an interruption (be it a function passed to
+ INTERRUPT-THREAD or a timer function) runs in an environment where
+ interrupts can be enabled. The interruption can use
+ WITH-INTERRUPTS or WITHOUT-INTERRUPTS as it sees fit. Use
+ WITHOUT-INTERRUPTS to avoid nesting of interruptions and
+ potentially running out of stack. Keep in mind that in the absence
+ of WITHOUT-INTERRUPTS some potentially blocking operation such as
+ acquiring a lock can enable interrupts.
+ * incompatible change: GC-OFF and GC-ON are removed, as they were
+ always unsafe. Use WITHOUT-GCING instead.
+ * new feature: runtime option --disable-ldb
+ * new feature: runtime option --lose-on-corruption to die at the
+ slightest hint of possibly non-recoverable errors: running out of
+ memory, stack, alien stack, binding stack, encountering a memory
+ fault, etc. In the absence of --lose-on-corruption a warning is
+ printed to stderr.
+ * enhancement: detect binding stack exhaustion
+ * enhancement: detect alien stack exhaustion on x86/x86-64
+ * improvement: generally more stable and reliable interrupt handling
+ * improvement: there is a per thread interruption queue,
+ interruptions are executed in order of arrival
+ * improvement: a repeating timer reschedules itself when the it has
+ finished, but expiration times are spaced equally. If an
+ expiration time is in the past it will trigger after a short grace
+ period that may give a chance to other things to run.
+ * optimization: slightly faster gc on multithreaded builds
+ * optimization: faster WITHOUT-GCING
+ * bug fix: when JOIN-THREAD signals an error, do it when not holding
+ important locks so that the debugger/handler doesn't produce
+ recursive errors or deadlock.
+ * bug fix: real-time signals are not used anymore, so no more
+ hanging when the system wide real-time signal queue gets full.
+ * bug fix: INTERRUPT-THREAD on a dying thread could produce memory
+ fault.
+ * bug fix: finalizers, gc hooks never run in a WITHOUT-INTERRUPTS
+ * bug fix: fix random memory faults related to interrupts on alpha
+ * bug fix: fix random memory faults related to interrupts on sparc
+ * bug fix: fix deadlocks related to starting threads
+ * bug fix: fix deadlines on locks on futex platforms
+ * bug fix: restore errno in signal handlers
+ * bug fix: fix deadlocks related to hash tables
+ * bug fix: fix deadlocks in pcl
+
changes in sbcl-1.0.25 relative to 1.0.24:
* incompatible change: SB-INTROSPECT:FUNCTION-ARGLIST is deprecated, to be
removed later. Please use SB-INTROSPECT:FUNCTION-LAMBDA-LIST instead.
computes the right offset for the memory copy.
* bug fix: compilation problem involving inlined calls to aliens with
result type VOID. (reported by Ken Olum)
+ * bug fix: #235a; sequential inline expasion in different policies no
+ longer reuses the functional from the previous expansion site.
+ * bug fix: DEFTYPE no longer breaks on bodies consisting of a single
+ unquoted symbol. Regression from 1.0.22.8. (reported by Ariel Badichi)
+ * bug fix: named ENUMs in multiply-referenced alien record types no longer
+ cause an implied type redefinition. Regression from 1.0.21.29.
+ * bug fix: sign-extension of small signed return values now works with C
+ code compiled with gcc 4.3 or newer. (reported by Liam Healy)
+ * improvements to the Windows port:
+ ** SB-BSD-SOCKETS now works from saved cores as well. (reported by Stephen
+ Westfold, thanks to Rudi Schlatte)
changes in sbcl-1.0.24 relative to 1.0.23:
* new feature: ARRAY-STORAGE-VECTOR provides access to the underlying data
