- Update to version 2.4.3
  * enhancement: when dumping debug information to fasl files, the system
    respects the SOURCE_DATE_EPOCH environment variable (if set) as the latest
    timestamp to be used.
  * contributed module: the sb-perf contributed module, an interface
    originally by Luke Gorrie to Linux's perf, is now included by default on
    Linux.  (Thanks to Philipp Marek)
  * platform support:
    ** on Linux and BSD variants, timezone querying is now faster.
    ** Arm64/Darwin: allow configuring the system with a relocatable static
       space.
    ** PPC64: allow configuring the system with fasteval.
  * bug fix: erroneous transform of EQUALP on characters (lp#2055425)
  * bug fix: float rounders (FTRUNCATE and related functions) handle minus
    zero more consistently, returning minus zero as the primary value when
    rounding to zero from a negative value.
  * bug fix: type checks for (VECTOR T) were giving the wrong answer for
    vectors displayed to simple multi-dimensional arrays.  (reported by
    _death)
  * bug fix: do not transform away division by BIT when the BIT might still
    include 0.  (lp#2056184, reported by xizang)
  * bug fix: various errors related to imperfections in the perfect hash
    generator.  (lp#2055794, lp#2056341)
  * bug fix: respect declarations for symbol macros inside defmethod.
    (lp#2056514, reported by Jonathan Braud)
  * bug fix: failure to set structure slots to floats on Arm64.  (lp#2058148,
    reported by Bibek Panthi)
  * optimization: improvements to the implementation of CASE.
  * optimization: faster PARSE-INTEGER :radix 10/16 on word-sized integers.
  * optimization: improvements to LOGBITP.

- Update to version 2.4.2
  * bug fix: restore the ability to inherit from both SEQUENCE and
    SB-MOP:FUNCALLABLE-STANDARD-OBJECT.  (lp#2050088, reported by Christophe
    Junke)
  * bug fix: COERCE will not convert lambda forms to functions if given a type
    naming a (strict) subclass of FUNCTION.
  * bug fix: LOG with a double-float and a ratio argument (in either order) do
    not lose precision through a single-float intermediate argument.
  * bug fix: LOG to the base 2 of integer powers of 2 are more likely to get
    the mathematically precise answer.
  * bug fix: LOG on ratios very near 1 with numerator or denominator being
    near a power of 2 will use log1p and so will lose less precision.
  * bug fix: the utf-8 external format with Unix line-endings updates its
    character size information when taking the fast path for a buffer of ascii
    characters.  (lp#2054169, reported by John Carroll)
  * bug fix: don't print the contents of a possibly no-longer-valid
    dynamic-extent cons in PRINT-OBJECT method for THREAD objects.
    (lp#2026195, reported by Jake Connor)
  * bug fix: place external entry points for functions consistently before any
    local functions.  (lp#2051169, reported by Fedorov Alexander)
  * bug fix: remove unactionable optimization notes for backquoted forms and
    ordinary calls to APPEND at high speed.  (lp#2051401, reported by Robert
    Brown)
  * bug fix: infinite loop in COPY-SEQ on zero-length arrays of element-type
    NIL.  (lp#2051759, reported by Devon Sean McCullough)
  * bug fix: fix compilation of non-top-level struct constructors.
    (lp#2052329, reported by Robert Poitras)
  * bug fixes in SB-SIMD:
    ** improve bounds checking in SB-SIMD.  (lp#2012010, reported by Patrick

- Update to version 2.4.1
  * enhancement: compact instance headers are partially supported with the
    mark-region parallel garbage collector.
  * enhancement: functions with declared return types have their return values
    type-checked in optimization regimes with high SAFETY and (DEBUG 3).
  * platform support:
    ** disable ASLR on FreeBSD.  (lp#2047655, thanks to Konstantin Belousov)
    ** link to libpthread on FreeBSD.  (thanks to Konstantin Belousov)
    ** restore build on 64-bit riscv.  (lp#2034713, lp#2048869, reported by
       Guillaume LE VAILLANT)
    ** restore build on 64-bit ppc.
    ** fix case in referring to a header file.  (lp#2047726, thanks to Andrew Kravchuk)

       available on all platforms.
  * bug fix: resweep moved lines after compaction in the mark-region parallel
    garbage collector.
  * bug fix: infinite loops in the compiler on some constructs with SATISFIES
    types.  (lp#2047289, lp#2047706, lp#2049631)
  * optimization: various hash tables implementing part of the system
    (packages, Unicode data tables) have been converted to use perfect hash
    functions.
  * optimization: TYPECASE on structure class hierarchies is implemented using
    a perfect hash.
  * optimization: eliminate bound checks with relative offsets.  (lp#1830314)
  * optimization: the compiler has more knowledge of how to optimize

- Update to version 2.4.0
  * minor incompatible change: *COMPILE-VERBOSE* and *LOAD-VERBOSE* are bound
    to NIL when the system is started with the --script command-line argument.
    (reported by Hraban Luyat, thanks to Nicolas Martyanoff)
  * minor incompatible change: when looking for its core file, the system
    checks the validity of whatever is pointed to by /proc/self/exe, and
    assesses argv[0] if /proc/self/exe is invalid.  (thanks to Philipp Marek)
  * minor incompatible change: the system no longer provides type names on the
    standard (CL) symbols ARRAY-RANK, ARRAY-TOTAL-SIZE, PATHNAME-HOST,
    PATHNAME-TYPE, PATHNAME-DIRECTORY, FLOAT-RADIX or FLOAT-DIGITS.
    (lp#2045559)
  * platform support
    ** the mark-region parallel garbage collector can be enabled on arm64.
       (Thanks to Hayley Patton)
    ** fix build on modern FreeBSDs.  (lp#2046996, thanks to David J. Flander)
  * bug fix: restore compiler type inference correctness on calls to REDUCE
    with :INITIAL-VALUE but no :FROM-END.  (lp#2044856, reported by Patrick
    Poitras)
  * bug fix: compiler error when declaring SB-EXT:MUFFLE-CONDITIONS on an
    unknown type.  (lp#2045442)
  * bug fix: the disassembler provided non-pretty output for registers in some
    cases.  (lp#2046004, reported by Fedorov Alexander)
  * bug fix: the system is slightly less likely to exhaust the stack again
    when reporting a control stack exhaustion error.
  * optimization: GC write barriers are eliminated in more cases.
  * optimization: improved type derivation of iteration variables with mixed
    types.
  * optimization: remove unused initial values from LET bindings, improving
    register type selection.

John Paul Adrian Glaubitz (glaubitz) 5 months ago (revision 197)

- Update to version 2.3.11
  * minor incompatible change: streams with an external-format specified with
    :REPLACEMENT will use their replacement data once per stream unit that
    causes a decoding error (rather than, in some cases, once for a sequence
    of bytes none of which is a valid character start position for that
    external-format).
  * minor incompatible change: external-format designators with unsupported or
    unrecognized options now signal an error when used.
  * enhancement: During generic function dispatch, for a generic function
    using standard- or short-method-combination, if there are no applicable
    primary methods the system will call the generic function
    SB-PCL:NO-PRIMARY-METHOD, whose default behaviour is to signal an error.
    Users may define methods on this generic function.
  * enhancement: external formats for unibyte encodings and utf-8 now support
    newline variants.
  * enhancement: character decoding and encoding errors signalled by stream or
    octet functions now provide a USE-VALUE restart for handlers to provide
    replacement input or output.
  * enhancement: READ-SEQUENCE and WRITE-SEQUENCE support user-defined
    sequences; the default implementation proceeds element-by-element, reading
    or writing single bytes or characters to or from the stream as
    appropriate.
  * bug fix: OCTETS-TO-STRING using unibyte external formats with unallocated
    codepoints (e.g. iso-8859-3) correctly signal or use replacements rather
    than taking bits from the address of NIL and converting those bits to
    a character.
  * bug fix: FILE-STRING-LENGTH now returns NIL if the input datum is not
    encodable in the stream's external format.
  * bug fix: table-based multibyte external formats (EUC-JP, Shift-JIS, GBK)
    now honour a replacement character (in the external format or through

- Update to version 2.3.10
  * enhancement: The compiler now allows stack allocating vectors of any size
    on all safety levels, not just those which it can prove are of sub-page
    sizes. It can do this because it now inserts code to check for stack
    overflow explicitly on higher safety levels.
  * enhancements to the disassembler:
    ** on arm64, x86-64, DISASSEMBLE annotates references to static symbols.
  * bug fix: calls to generic functions now detect erroneous keywords (in the
    sense of CLHS 7.6.5) passed as arguments even when auxiliary methods are
    applicable.
  * bug fix: the standard method on SB-MOP:COMPUTE-EFFECTIVE-METHOD no longer
    inserts calls to implementation-defined local macros.  (reported by Daniel
    Kochmański)
  * bug fix: compiler error from state-machine-like LABELS forms in some
    circumstances.  (lp#2037318)
  * bug fix: fix compile-time error in constant-folding RATIONAL on literal
    float infinities.  (lp#2037455)
  * bug fix: failure on x86-64 to assemble code for EQL tests of comparisons
    with immediates.  (lp#2037456)
  * bug fix: infinite loop in the compiler for simplification of type tests of
    complicated union types.  (lp#2038112, reported by Paul M. Rodriguez)
  * bug fix: inability to dump a literal displaced array containing copies of
    its displacement target.  (lp#2038233, reported by James Kalenius)
  * bug fix: compiler error in LOGBITP type derivation.  (lp#2038241)
  * bug fix: compiler error in AREF type derivation.  (lp#2038659)
  * bug fix: compiler internal consistency failure in overflow type checks.
    (lp#2038736)
  * bug fix: work around an infinite loop in type simplification by not
    providing such types from the compiler.  (lp#2038980, reported by Richard
    Holcombe)

- Update to version 2.3.9
  * enhancement: stack allocation via DYNAMIC-EXTENT now applies to all values
    that a variable can take on (for example via SETQ), not just the initial
    binding. This permits for example building complex or recursive structures
    on the stack more easily via iteration. See the updated manual entry for
    more details.
  * minor incompatible change: some interfaces in the SB-POSIX contrib module
    adhere to the spec that a NULL result from the C library is an error if
    and only if errno was altered by the call. SYSCALL-ERROR will be signaled
    if so.
  * enhancement: the SB-POSIX contrib module provides DO-PASSWDS and DO-GROUPS
    to allow users to iterate over password and group databases safely.
  * platform support:
    ** support for Darwin on x86 and PowerPC has been restored.  (lp#2033287,
       thanks to Kirill A. Korinsky, Sergey Fedorov and barracuda156)
  * bug fix: miscompilation due to erroneous type derivation in the presence
    of multiplication of fixnums by ratios.  (lp#2033695, reported by Patrick
    Dussud)
  * bug fix: compiler error when compiling signed- and unsigned 64-bit type
    checks in some cases.  (lp#2033997, reported by Eric Smith)
  * bug fix: compiler error when the :INITIAL-CONTENTS argument to MAKE-ARRAY
    is a constant non-sequence.  (lp#2037328)
  * bug fix: compiler error when constant-folding sequence functions with
    :TEST or :KEY functions erroring on the given sequence.  (lp#2037341)
  * bug fix: compiler error when arguments to array or sequence functions
    imply a very large sequence size.  (lp#2037443, lp#2037348)
  * bug fix: compiler error when the return value of ADJUST-ARRAY is not used.
    (lp#2037450)
  * optimization: function types derived by the compiler can in some cases be
    propagated backwards through the intermediate representation.

- Update to version 2.3.8
  * enhancement: a mark-region parallel garbage collector is available as a
    build-time option; it can be enabled by adding
      `--without-gencgc --with-mark-region-gc`
    to the build command line.  (Thanks to Hayley Patton)
  * enhancement: Stack allocation via DYNAMIC-EXTENT is now possible for
    conditionals even when not all branches are stack-allocatable. Previously
    all branches needed to be stack-allocatable for the otherwise-inaccessible
    subparts to get stack allocated.
  * platform support:
    ** on Mac OS X Sonoma, loading the memory image no longer fails.
       (lp#2029430, reported by cladur)
    ** on Darwin, we no longer reimplement nanosleep().
    ** on PPC64, undefined function errors now work.
    ** on ARM64/OpenBSD, enable the GCC TLS feature. (thanks to Sébastien
       Marie)
    ** when building the system, only display a reasonable amount of timing
       precision.  (thanks to Philipp Marek)
  * bug fix: handling of inlining functions compiled to return unboxed values
    no longer crashes the compiler.  (lp#2029020, reported by Pascal
    J. Bourguignon)
  * bug fix: the source location for code executed within a top-level
    (EVAL-WHEN (:COMPILE-TOPLEVEL) ...) form is now more useful.
  * bug fix: address a race between user threads cancelling finalizers and the
    finalizer thread executing them.  (lp#2029306)
  * bug fix: complex division returns the same value when evaluated inline and
    out-of-line.  (lp#2030097)
  * bug fix: the pretty-printer no longer deletes syntactically-significant
    whitespace immediately preceding a newline.  (lp#1985814, reported by Mark
    David)

- Update to version 2.3.7
  * minor incompatible change: MACROLET macro functions are now compiled with
    (SPEED 1), leading to fewer efficiency notes being emitted when compiled
    in otherwise high-SPEED environments.
  * minor incompatible change: when coalescing list data, the file compiler
    respects substructure equality more accurately, with the side-effect of
    coalescing along CDR chains as well as CARs.  (lp#2025086)
  * minor incompatible change: FUNCTION type declarations for local variables
    generate assertions around their use when called.
  * platform support
    ** on OpenBSD, the regression test suite expectations have been updated.
       (lp#2026809, thanks to Sebastien Marie)
    ** on OpenBSD, the data limit is now 1GB.  (lp#2027536, thanks to
       Sebastien Marie)
    ** on Darwin with the SB-FUTEX feature, do not use unpaired
       mach_thread_self() syscalls, avoiding resource leaks when creating
       threads.
    ** on 64-bit RISCV, add support for some REM-by-multiplication
       optimizations.
    ** on Windows, work around a C compiler bug relating to SYSV_ABI.
  * bug fix: FILE-POSITION on string output streams no longer crashes or
    causes arbitrary memory overwrites.  (lp#1839040)
  * bug fix: the compiler no longer constant-folds POSITION to NIL if the
    START or END arguments are not valid.
  * optimization: the compiler derives types of &KEY arguments in local calls.
    (lp#655562)
  * optimization: type tests of values of known union type can be faster if
    the type being tested for has a non-trivial intersection with the known
    type.
  * optimization: the low-level implementation of NUMBERP, REALP and RATIONALP

- Update to version 2.3.6
  * platform support:
    ** restore building contribs on riscv; (lp#2002930)
    ** shorter constant-loading sequences on riscv;
    ** on OpenBSD, map the stack without executable permission (thanks to
       Sébastien Marie)
    ** Restore OpenBSD/arm64 for OpenBSD 7.3 (lp#2024003, reported by Robert
       Palm)
  * bug fix: AREF on multidimensional arrays with the wrong number of indices
    now signals an error.  (lp#2022327, reported by EU)
  * bug fix: the nature of NIL as both STRING and SEQUENCE is correctly handled
    in the compiler's handling of string functions.  (lp#2023118, reported by
    Patrick Poitras)
  * bug fix: the sb-bsd-sockets tests no longer fail on systems configured
    without IPv6.  (reported by Will Senn)
  * bug fix: the compiler no longer transforms into incompletely-known functions
    (lp#1824351)
  * optimization: better (the word-sized-type (ASH word-sized word-sized))
    when the result can overflow. For arm64 and x86-64.
  * optimization: better unoptimized calls to CEILING, FLOOR.
  * optimization: functions that involve coercing floats now cons less.
    For arm64 and x86-64.
  * optimization: array displacement to simple arrays is slightly faster.
