changes in sbcl-1.4.4 relative to sbcl-1.4.3:
  * bug fix: pathname accessors such as PATHNAME-DIRECTORY work on
    SYNONYM-STREAMs.
  * bug fix: (pathname-{device,directory,name,type} ... :case :common) works
    as expected. In particular MAKE-PATHNAME composed with the accessors
    roundtrips properly when both use the same :case. (lp#1739906)
  * bug fix: DIRECTORY no longer gets confused when the value of
    *DEFAULT-PATHNAME-DEFAULTS* has a name or type component. (lp#1740563)
  * bug fix: pattern pieces in pathname components are correctly escaped
    during unparsing.
  * bug fix: DELETE-DIRECTORY no longer signals an error when the directory is
    supplied as a pathname with name and/or type components containing escaped
    characters. (lp#1740624)
  * bug fix: weak hash-tables no longer cause GC time to scale superlinearly
    (lp#1241771)
  * bug fix: CANCEL-FINALIZATION operates in approximately constant time
    per operation (lp#1587983)
  * bug fix: big-endian MIPS systems now (mostly) work again (broken since
    1.3.14.x).
  * bug fix: backtrace from arg-count errors on systems other than x86, x86-64,
    ARM, and ARM64 now works again.
  * bug fix: backtrace from asynchronous interrupts on non-x86, non-x86-64
    systems should now be more reliable.
  * enhancement: warnings and errors referring to bindings established by LET,
    LET*, FLET and LABELS point to the offending form more accurately.
  * enhancement: backtrace for invalid argument count produces the exact
    supplied arguments including the extra ones on all platforms (no longer
    just x86, x86-64, ARM, and ARM64).

sbcl Debian release 2:1.4.3-1

Upstream version 1.4.3

changes in sbcl-1.4.3 relative to sbcl-1.4.2:
  * enhancement: SLEEP respects deadlines established by SB-SYS:WITH-DEADLINE.
  * bug fix: DECODE-TIMEOUT and operators accepting a timeout no longer signal
    an error when called with an argument that is of type (real 0) but not
    (unsigned-byte 62) (lp#1727789)
  * bug fix: fixed heap exhaustion bug when consing millions of small objects
  * bug fix: sb-safepoint builds are now a lot less prone to deadlocks and odd
    crashes (lp#1424031, lp#1268710)
  * bug fix: argumentless CALL-NEXT-METHOD where specialized-to-T or
    unspecialized parameters are mutated now uses the original (non-mutated)
    parameter values (lp#1734771)
  * bug fix: memory faults from lisp no longer use (thread-and-interrupt
    unsafe) global storage for fault addresses (everywhere), and now have
    cleaner backtraces (on x86 and x86-64). (lp#309068)
  * bug fix: pathnames with a directory component of the form
    (:absolute {:up,:wild,:wild-inferiors}) no longer fail to unparse.
    (lp#1738775)
  * bug fix: more reliable signal handling on macOS.

sbcl Debian release 2:1.4.2-1

changes in sbcl-1.4.2 relative to sbcl-1.4.1:
  * minor incompatible change: SB-EXT:QUIT is no longer marked as deprecated
    and behaves like SB-EXT:EXIT.
  * enhancement: ASDF updated to 3.3.1. The ASDF release is dedicated to
    the late Elias Pipping who put enormous amounts of work into it despite
    his terminal illness. Thank you and rest in peace.  (lp#1681201)
  * enhancement: alien routines compiled with '-fsanitize=thread' and/or
    '-fsanitize=memory' cause fewer false positives in error reporting.
  * optimization: fewer instances of consing float constants at runtime.
  * bug fix: a number of compiler bugs detected by Paul F. Dietz' randomized
    tester.  (lp#1731503, lp#1730699, lp#1723993, lp#1730434, lp#1661911,
    lp#1729639, lp#1729471, lp#1728692)
  * bug fix: better errors from NAMESTRING and friends on pathnames with no
    namestrings.  (lp#792154)
  * bug fix: EQUAL and EQUALP compiler transforms were too confident in
    deriving a result.  (lp#1732277, lp#1732225)
  * bug fix: FILL sometimes returned the underlying data vector rather than
    the given array.  (lp#1732553)
  * bug fix: SEARCH returned the wrong answer in some cases.  (lp#1732952)
  * bug fix: the type (COMPLEX INTEGER) behaves more as specified by Function
    TYPEP, which has stronger constraints than System Class COMPLEX.
    (Reported by Eric Marsden, lp#1733400)

sbcl Debian release 2:1.4.1-1

sbcl Debian release 2:1.3.14-2

changes in sbcl-1.4.1 relative to sbcl-1.4.0:
  * optimization: faster foreign callbacks.
  * enhancement: complex arrays can be stack allocated.
  * enhancement: PROCESS-KILL now exists on win32 and PROCESS-PID actually
    returns the PID.
  * optimization: the register allocation method used by the compiler when
    optimizing for speed is now faster for functions with large bodies.
  * bug fix: SB-INTROSPECT:ALLOCATION-INFORMATION works on big-endian CPUs
    (fixes lp#490490 for real rather than by disabling a test)
  * bug fix: code objects and bignums of large enough size to be placed
    on GC pages without any other object no longer cause accidental copying
    during garbage collection. (gencgc only)
  * bug fix: sb-fasteval failure with 0-argument lambdas (lp#1722715)
  * bug fix: RUN-PROGRAM doesn't leak handles on win32 and PROCESS-CLOSE
    doesn't crash. (lp#1724472)

changes in sbcl-1.4.0 relative to sbcl-1.3.21:
  * minor incompatible change: DESTRUCTURING-BIND treats non-toplevel () as
    nested empty pattern. This seems to be what the standard mandates, so
    conforming code should not be affected.
  * ehancement: (GC :GEN 7) with gencgc will zero-fill dead pseudo-static
    objects so that they do not spuriously cause reachability of objects that
    would have been otherwise dead.
  * enhancement: PROCESS-STATUS now tracks stopped and continued processes
    properly (also fixes lp#1624941, based on patch by Elias Pipping).
  * bug fix: INSPECT handles errors signaled while printing slot
    values. (lp#454682)
  * bug fix: DESCRIBE works on classes like it used to.
  * bug fix: *LOAD-PATHNAME* and *LOAD-TRUENAME* are bound to pathnames
    when processing a sysinit or userinit file
  * bug fix: save-lisp-and-die is able to collect more garbage on non-x86oid
    gencgc targets.
  * bug fix: fixed out-of-bounds array read in optimized POSITION on bit-vectors
  * bug fix: signal emulation respects the 128-byte stack red zone on x86-64
    macOS.

changes in sbcl-1.3.21 relative to sbcl-1.3.20:
  * minor incompatible change: the CLOBBER-IT restart for defstruct redefintion
    has been removed after a 15 year deprecation cycle. Use the new name,
    RECKLESSLY-CONTINUE. Note also that this restart is hidden if deemed unsafe
    due to altered placement of untagged slots in the structure.
  * enhancement: the assignment of -DSBCL_PREFIX= in src/runtime/GNUmakefile
    can be removed as a local patch, which results in an sbcl executable
    that finds its core file relative to itself by looking in "../lib/sbcl".
  * enhancement: backends using the generational GC are able to relocate
    dynamic space anywhere the operating system places it.
    This feature can be disabled by removing :relocatable-heap from the
    build configuration. Not supported on Windows.
  * enhancement: DEFMETHOD no longer signals IMPLICIT-GENERIC-FUNCTION-WARNING.
  * enhancement: better type conflict detection for high order functions, e.g.
    (find x "123" :test #'=)
  * enhancement: the tabular output of ROOM is aligned dynamically, preventing
    misaligned tables for larger sizes or counts.
  * enhancement: ROOM reports on immobile space if applicable.
  * optimization: optimized external-format routines.
  * bug fix: SB-INTROSPECT:ALLOCATION-INFORMATION returns :IMMOBILE
    instead of :FOREIGN for objects in immobile space.
  * bug fix: dotted lists in special forms and function call forms signal
    an appropriate error
  * bug fix: EQUALP hash tables with pathname keys now ignore internal slots.
    (lp#1712944, reported by Jason Miller)

changes in sbcl-1.3.20 relative to sbcl-1.3.19:
  * minor incompatible change: DEF{GENERIC,METHOD} no longer accept some
    illegal lambda lists such as (defgeneric bar (foo &key foo)) or
    (defgeneric baz (t)) that were accepted before.
  * optimization: a valueless &AUX binding in a BOA constructor does not
    force all slots reads in safe code to perform a full type check.
  * optimization: ATOMIC-PUSH and ATOMIC-POP generate better code
  * bug fix: the low-level debugger would erroneously print - or not print
    as the case may be - "(bad-address)" for some objects depending whether
    the --dynamic-space-size argument was used at Lisp startup
  * bug fix: a DEFCONSTANT with a non non-eql-comparable object as the value
    could cause miscompilation if that constant appeared as the default
    expression for an &OPTIONAL binding
  * bug fix: generic function lambda lists are now checked for repeated
    and otherwise illegal entries. (lp#1704114)
  * bug fix: setting gencgc_verbose = 1 could cause deadlock in fprintf()
    depending on the platform's stdio implementation. The relevant code
    has been changed to use snprintf() and write() instead.

changes in sbcl-1.3.19 relative to sbcl-1.3.18:
  * enhancement: specialized arrays can be printed readably without using
    *read-eval*
  * enhancement: SB-DEBUG:PRINT-BACKTRACE truncates huge string arguments.
    The full string remains available for inspection via (SB-DEBUG:ARG).
  * bug fix: backtracing from several threads at once could fail
  * bug fix: floating-point infinities could not be used as keys
    in EQUALP hash tables. (lp#1696274)
  * bug fix: random sb-fasteval failures. (lp#1642708)
  * bug fix: align the stack in callback wrappers to defend against C
    compiler over-aggressive use of SIMD.  (lp#1697528)
  * bug fix: don't try to find the class when reporting that a class does
    not exist for a primitive type.  (lp#1697226)

changes in sbcl-1.3.18 relative to sbcl-1.3.17:
  * minor incompatible change: existing values of CFLAGS, ASFLAGS,
    CPPFLAGS, and LINKFLAGS will be incorporated into C compiler
    invocations when building from source.
  * minor incompatible change: the result of WRITE-TO-STRING may be
    a BASE-STRING if all characters written are of type BASE-CHAR.
  * minor incompatible change: the broadcast stream with no output
    streams is a singleton object. That object satisfies OPEN-STREAM-P
    regardless of how many times CLOSE is invoked on it.
  * enhancement: x86[-64] backends contain an experimental feature
    which aids in demonstrating reachability of any object starting
    from a tenured object or a thread stack by producing a proof
    as a sequence of pointers to follow.
    The file "tests/traceroot.test.sh" contains an example usage.
  * enhancement: if the alien symbol "gc_coalesce_string_literals" is
    set to 1 prior to SAVE-LISP-AND-DIE, then similar string constants
    loaded from different fasl files may be collapsed to one object.
    If the variable is set to 2, then additionally strings which are
    STRING= in code resulting from COMPILE can be coalesced.
    For instance, two functions returning the literal string "HI"
    might return EQ strings after collapsing, which may be undesired
    in a particular use. The flag pertains to gencgc only.
  * enhancement: SXHASH values on pathnames are better distributed
  * bug fix: MAKE-PATHNAME removes empty strings as components of a
    directory, as is permitted: "Whenever a pathname is constructed
    the components may be canonicalized if appropriate."
  * optimization: various printer and FORMAT performance enhancements.
  * bug fix: GET-FOREGROUND no longer fails in case all other interactive
    threads exit (lp#1682671, reported by Syll)
  * bug fix: RELEASE-FOREGROUND always removes the current thread from the
    list of interactive threads. (lp#1682867, reported by Syll)

changes in sbcl-1.3.17 relative to sbcl-1.3.16:
  * enhancement: memory overhead from the garbage collector's metadata
    is reduced on 64-bit architectures; no change for 32-bit.
  * enhancement: further garbage collector speedups affecting
    pinned objects on conservative backends, and simple-vectors.
  * enhancement: on Linux a custom handler for SIGSEGV can be called
    for page faults outside of dynamic space by changing the C symbol
    "sbcl_fallback_sigsegv_handler".
  * bug fix: sb-cover does not lose source positions for AND/OR/COND.
  * bug fix: random disassembler failures. (lp#1527931)
  * The bundled sb-md5 contrib has been updated to release 2.0.4
    which is licensed under Creative Commons CC0 per author's statement
    https://github.com/pmai/md5/commit/fd134e71b71a10ab78905833a7cb9d4d6817c589
    (Refer to NEWS and COPYING in the contrib/sb-md5 subdirectory)

changes in sbcl-1.3.16 relative to sbcl-1.3.15:
  * optimization: various small tweaks give around 5% faster garbage
    collection
  * bug fix: better detection of when an impossible code path does
    not need a warning.  (lp#1668619)
  * bug fix: stronger attempts to disable position-independent
    executable building.  (lp#1668986, patch from Mark Wright)
  * bug fix: OPEN :IF-EXISTS NIL signalled a condition on Windows.
    (lp#1674437, reported by Jan Idzikowski)

changes in sbcl-1.3.15 relative to sbcl-1.3.14:
  * minor incompatible change: the reader will when feasible create
    new symbols using a BASE-STRING for the print name.  Additionally,
    string literals can favor the base-string type if desired, though
    the default is to always return UTF-32 strings for compatibility.
    A preference for base-string does not disable reading Unicode.
    The choice is controlled via (SETF READTABLE-BASE-CHAR-PREFERENCE).
    If Unicode was disabled at build time, this setting does nothing.
  * enhancement: SBCL generates more debug information by default.
  * enhancement: type errors provide context information, such as which
    variable is being bound, which slot of which structure is being set.
  * enhancement: if #+immobile-symbols is in build-time *FEATURES* (not
    enabled by default), then symbols will never be moved in memory
    except by SAVE-LISP-AND-DIE. Immobility has helpful implications for
    code generation as well as interaction with foreign routines.
    This feature can only be enabled if #+immobile-space is enabled.
  * enhancement: undefined function errors can be restarted on x86-64, to
    either retry calling the function again or call a user supplied function.
  * enhancement: sb-ext:restrict-compiler-policy accepts an upper bound in
    addition to a lower bound.
  * enhancement: #+immobile-code improves the speed of function calling.
    Some delay may be noticed when redefining an existing function
    from a saved core file however.
  * defaults change: sb-ext:*disassemble-annotate* default to NIL, due to its
    poor reliability.
  * new feature: SB-LINKABLE-RUNTIME, allowing linking with extra object
    files to help with delivery of executables.  (Thanks to François-René
    Rideau)
  * bug fix: data race in GENTEMP fixed - it can no longer return the
    same interned symbol to multiple threads if called concurrently
  * bug fix: interrupting LOADing of FASLs does not leave functions without
    source locations. (lp#540276)
  * bug fix: DYNAMIC-EXTENT-declared results of NOTINLINE local functions were
    treated as if they were actually stack allocated (lp#1659964)
  * bug fix: correctly handle the case of a non-local exit within a function
    terminating the extent of dynamic-extent, dynamic-bound variables in the
    presence of multiple-values (lp#1655011)
  * bug fix: handling of SB-SYS:WITH-PINNED-OBJECTS in the interpreters (both
    sb-eval and sb-fasteval) now actually pins objects on gencgc.
  * bug fix: AVX registers are preserved during exceptions on x86-64 macOS.
  * bug fix: (directory "SOMETHING/*/**/MORE") is no longer equivalent to
    (directory "SOMETHING/**/MORE")
  * bug fix: better console IO on Windows (lp#1660906)

changes in sbcl-1.3.14 relative to sbcl-1.3.13:
  * minor incompatible change: the SB-PCL walker no longer recognizes
    macros expanding into a DECLARE expression. This is not a language change,
    since ANSI forbids such usage (X3J13 issue DECLARE-MACROS:FLUSH).
  * enhancement: for several macros such as MULTIPLE-VALUE-{BIND,SETQ}, COND,
    DO{,*,LIST}, {RESTART,HANDLER}-{BIND,CASE}, *CASE, conditions signaled
    during macroexpansion point to the form that caused the problem more
    accurately.
  * enhancement: the "--noinform" command-line option inhibits output from
    save-lisp-and-die in addition to removing the startup banner.
  * bug fix: PROCESS-KILL failed to return errno if the system call failed
  * optimization: slightly more comprehensive treatment of the keyword
    arguments to MAKE-ARRAY in compiler transformations.

changes in sbcl-1.3.13 relative to sbcl-1.3.12:
  * enhancement: SET triggers package locks on undefined variables.
    (lp#1645152)
  * enhancement: new Windows specific option to run-program, :escape-arguments
    (lp#1503496)
  * enhancement: recompiling a MAKE-INSTANCE form with an initarg :INITARG
    CONSTANT where CONSTANT names a constant variable picks up the new value
    of CONSTANT in case it has been redefined. (lp#1644944)
  * optimization: faster TYPEP on undefined at compile-time types and upcoming
    class definitions. (lp#1082967)
  * optimization: memory consumption of each STANDARD-OBJECT instance is
    reduced by 2 words if the compact-instance-header feature is enabled.
  * optimization: CONDITION instances are quicker to allocate.
  * optimization: unoptimized calls to FILL on specialized vectors are now
    just as fast as T vectors.
  * bug fix: get-timezone returns corret DST on 64-bit Windows. (lp#1641058)
  * bug fix: cross reference information in fasls is no longer incompatible
    between different cores (lp#1648186)

changes in sbcl-1.3.12 relative to sbcl-1.3.11:
  * enhancement: on x86-64, compiled functions loaded from fasl files
    can not be moved, but can be freed, by GC. Additionally, COMPILE will
    produce immobile code if SB-C::*COMPILE-TO-MEMORY-SPACE* is set to
    :IMMOBILE. (Caution: the flag is experimental and subject to change.)
    The benefits are better physical separation of code from data,
    and potentially easier examination of live images by external tools.
  * enhancement: the docstring for SAVE-LISP-AND-DIE has been amended to
    say that the :ROOT-STRUCTURES parameter is not meaningless on gencgc,
    depending on the platform.
  * bug fix: calling a named function (e.g. a DEFUN) concurrently with
    redefining that same function could lead to execution of random bytes.
  * bug fix: yes-or-no-p accepts formatter functions (lp#1639490)
  * bug fix: better handling of exceptions on macOS.
