  * Fix SIGSEGV in protobuf_c_message_check() on messages with unpopulated
    oneof members (#358).

  [ Italo Guerrieri ]
  * Do not allow tag values of 0 in protobuf messages, as these are not
    allowed by proto2 or proto3 (#299).

protobuf-c (1.3.1)

  [ Robert Edmonds ]
  * Release 1.3.1.

  * Restore protobuf-2.x compatibility (#284, #285).

  * Use xenial and protobuf 3.6.1 in the Travis-CI environment (#332).

    to compile against protobuf 3.6.1 (#320, #333).

  * Use AX_CXX_COMPILE_STDCXX macro to enable C++11 support in old compilers
    (#312, #317, #327, #334).

  [ Fredrik Gustafsson ]
  * Add std:: to some types (#294, #305, #309).

  [ Sam Collinson ]
  * Check the return value of int_range_lookup before using as an array index;
    it can return -1 (#315).

  [ Matthias Dittrich ]
  * Fix compilation on mingw by using explicit protoc --plugin=NAME=PATH syntax
    in Makefile.am (#289, #290).

  [ Adnan ]
  * Fix cmake build if built as part of an external project (#231).

  [ Gregory Detal ]
  * Remove .pb.{cc,h} in distdir instead of top_distdir in order to prevent
    removing files from other projects when protobuf-c is included as an
    autotools subproject (#232).

  [ Ben Farnham ]

  * Skip test suite when cross-compiling (#184).

protobuf-c (1.1.1)

  [ Robert Edmonds ]
  * Release 1.1.1.

  * Use protobuf 2.6.1 in the Travis-CI environment.

  [ Ilya Lipnitskiy ]
  * Munge C block comment delimiters in protobuf comments, preventing syntax
    errors in generated header files (Issue #180, #185).

  * Add static qualifier to ProtobufCEnumValue and ProtobufCEnumValueIndex
    variables in generated output.

  [ Oleg Efimov ]
  * Fix -Wpointer-sign compiler diagnostics in the test suite.

  * Check for NULL pointers in protobuf_c_message_free_unpacked()
    (Issue #177).

  * Exclude protoc-c and downloaded protobuf sources from Coveralls report.

  * Always define PROTOBUF_C__DEPRECATED, even on compilers that are not GCC
    (Issue #167).

  * Work around the lack of the 'inline' keyword in Microsoft compilers
    (Issue #167).

  * Add a CMakeLists.txt file as a fallback build system for Windows
    (Issue #168).

  [ Natanael Copa ]
  * Fix a build failure in the test suite that occurred with a parallel make
    running on a system with a large number of CPUs (Issue #156, #169).

protobuf-c (1.0.1)

  [ Robert Edmonds ]
  * Explicitly set the .data field of ProtobufCBinaryData's to NULL when
    unpacking a zero length byte string (Issue #157).

protobuf-c (1.0.0)

  [ Andrei Nigmatulin ]
  * Append "u", "ull", and "ll" integer literal suffixes for uint32, uint64,
    and int64 default values in generated code, in order to avoid "integer
    constant is so large that it is unsigned" compiler warnings.
    (Issue #136.)

  * Revert the problematic hash-based required field detection.
    (Related to Issue #60, #79, #137.)

  * Replace the 'packed' member of ProtobufCFieldDescriptor with a 'flags'
    word. Define flags for packed and deprecated fields. (Issue #138.)

  [ Dave Benson ]
  * Treat a "length-prefixed" wire-type message for a repeated field as
    packed-repeated whenever it makes sense (for all types other than
    messages, strings, and bytes).

  * Switch to New BSD license.

  * Add protobuf_c_message_check().

  * Compile error in packing 64-bit versions on some platforms
    (srobbins99: Issue #68 Comment 1).

  * Fix for memory error if the required-field check fails. See Issue #63
    for demo (w/ nice test case by dror.harari).

  * Add PROTOBUF_C_{MAJOR,MINOR} for compile-time checks and
    protobuf_c_{major,minor} for checks about the running library
    (Issue #53).

  * Use a small constant-size hash-table instead of alloca() for detecting
    required fields, and it also prevents us from using too much stack, etc.
    (Related to Issue #60, #79).

  * Add a macro to ensure enums are the size of ints (Issue #69).

  [ Ilya Lipnitskiy ]
  * Travis-CI integration.

  * Add source .proto filename to generated files.

  * Add protobuf-c version to protoc-c --version output (Issue #52).

  * For embedded submessage fields, merge multiple instances of the same
    field, per the protobuf documentation (Issue #91).

  * Don't print unpack errors by default.

  * Optionally allow running the test suite under valgrind with ./configure
    --enable-valgrind-tests. (Based on valgrind-tests.m4 from gnulib.)

  [ Kevin Lyda ]
  * Autoconf portability fixes.

  * Add doxygen detection and make targets to the build system.

  * Doxygen documentation for the libprotobuf-c public API (Issue #132).

  [ Nick Galbreath ]
  * Prevent possible overflow on 64-bit systems (Issue #106).

  [ Robert Edmonds ]
  * Remove CMake (Issue #87).

  * Modernize the build system.
    - Don't generate any diagnostics when building the build system with
      modern autotools (Issue #89).

    - Use the PKG_CHECK_MODULES macro to locate protobuf.

    - Use the AC_C_BIGENDIAN macro to detect endianness, rather than custom
      code.

    - Use the automake silent-rules option so the build output is actually
      readable.

    - Generate our own pkg-config .pc files.

  * Reorganize the source tree. This affects the public protobuf-c header
    path, which is now <protobuf-c/protobuf-c.h>. A compatibility symlink from
    <google/protobuf-c/> to <protobuf-c/> has been installed so that existing
    code will continue to compile. New code should at some point begin using
    the new include path, i.e., "#include <protobuf-c/protobuf-c.h>" rather
    than "#include <google/protobuf-c/protobuf-c.h>".

  * The RPC code has been split out into a separate project, protobuf-c-rpc.

  * Fix a potential use of an unitialized value in protobuf_c_message_unpack()
    and several memory leaks in protoc-c, discovered by a commercial static code
    analysis tool.

  * Bump the libprotobuf-c SONAME.

  * Begin versioning the library's symbols. (Based on ld-version-script.m4
    from gnulib.)

  * Preserve case in enum value names generated by protoc-c (Issue #129).
    Reported by Oleg Efimov.

  * Add library functions protobuf_c_version() and protobuf_c_version_string()
    for retrieving the version of the compiled library, and header macros
    PROTOBUF_C_VERSION and PROTOBUF_C_VERSION_STRING for retrieving the
    version of the header file. This replaces the interfaces for retrieving
    the protobuf-c version numbers in Issue #53.

  * Add a version guard that ensures that the output of protoc-c is only
    compiled against a protobuf-c header file from the exact same protobuf-c
    release.

  * Add a --enable-code-coverage option to configure, which enables a
    "make check-code-coverage" build target. This generates a code coverage
    report and requires the lcov tool to be installed.

  * Remove the old DocBook documentation in doc/c-code-generator.{html,xml}.
    Relevant material has been updated and incorporated into the Doxygen
    documentation in the protobuf-c header file.

  * Remove the protobuf_c_default_allocator and protobuf_c_system_allocator
    global variables from the exported library interface. All exported library
    functions that need to perform dynamic memory allocation receive a
    user-provided ProtobufCAllocator* parameter. If this parameter is NULL,
    the system's default memory allocator will be used.

    Client code that previously passed "&protobuf_c_system_allocator" to
    protobuf-c library functions taking a ProtobufCAllocator* argument should
    be updated to pass "NULL" instead.

    Client code that previously overrode protobuf_c_default_allocator with
    custom allocation functions and passed NULL as the ProtobufCAllocator*
    argument to protobuf-c library functions should be updated to instead
    enclose the custom allocation functions in a ProtobufCAllocator struct and
    pass this object to protobuf-c library functions taking a
    ProtobufCAllocator* parameter.

  * Update copyright and license statements throughout. The original
    protobuf code released by Google was relicensed from Apache-2.0 to
    BSD-3-Clause. Dave Benson also converted his license from BSD-3-Clause
    to BSD-2-Clause.

  [ Tomasz Wasilczyk ]
  * Don't export protobuf_c_message_init_generic() as an external symbol.

  * Don't use C++ style comments in C code.

  * Fix -Wcast-align warnings when compiled with clang.

      - bug in protobuf_c_dispatch_close_fd(), which usually only
        showed up in later function calls.
      - support for deprecated fields -- enable a GCC warning
        if a field has the "deprecated" option enabled. (Andrei Nigmatulin)
      - hackery to try to avoid touching inttypes.h on windows (Issue #41)
      - fix for protobuf_c_message_unpack() to issue error if any
        "required" field is missing in input stream. (Andrei Nigmatulin)

protobuf-c (0.13)
      - Fix for when the number of connections gets too great in RPC.
        (Leszek Swirski) (issue #32)
      - Add --disable-protoc to only build libprotobuf-c (daveb)
      - Bug fixes for protobuf_c_enum_descriptor_get_value_by_name()
        and protobuf_c_service_descriptor_get_method_by_name()
      - if descriptor->message_init != NULL, use it from unpack()
        as an optimization (daveb)
      - implement protobuf_c_{client,server}_set_error_handler()

protobuf-c (0.12)
      - for field names which are reserved words, use the real name
        given in the protobuf-c file, not the mangled name which
        is the name of the member in the C structure.  (Andrei Nigmatulin)
      - add protobuf_c_message_init() function; add virtual function
        that implements it efficiently.  (Andrei Nigmatulin)
      - bug fix for sfixed32, fixed32, float wire-types on
        big-endian platforms (Robert Edmonds)

        is now wire_format.h) (Robert Edmonds)

protobuf-c (0.11)
      - allow CFLAGS=-DPRINT_UNPACK_ERRORS=0 to suppress
        unpack warnings from being printed at compile time (Andrei Nigmatulin)
      - give error if an unknown wire-type is encountered (Andrei Nigmatulin)

protobuf-c (0.10)
      - build issue on platforms which don't compute library dependencies
        automatically.
      - fix for certain types of corrupt messages (Landon Fuller) (issue 16)

protobuf-c (0.9)
      - build issue: needed $(EXEEXT) in dependency lists for cygwin
      - bug fix:  protobuf_c_service_get_method_by_name() was not correct b/c
        the service's methods were not sorted by name (the header file
        used to incorrectly state that they were).
        Now we correctly implement protobuf_c_service_get_method_by_name()
        (using a bsearch indexed by separate array).
      - generated source incompatibility:  we added a new
        member to ProtobufCServiceDescriptor (method_indices_by_name).
        You will have to run the latest protobuf
        to generate those structures.
      - rename rpc-client's "autoretry" mechanism to "autoreconnect".

      - add RPC system (BETA)
      - don't segfault when packing NULL strings and messages. (issue 13)

protobuf-c (0.7)
      - memory leak:  unknown fields were not being freed by free_unpacked()
      - lowercase field names consistently when composing
        default_value names. (issue 11)
      - remove spurious semicolon (issue 10)

protobuf-c (0.6)
      - Warning suppression for -Wcast-qual and -Wshadow.
      - Support for default values of all types allowed by core protobuf.
      - Generate message__init functions, for when the static initializer
        isn't convenient.
      - add some reserved fields at the end of the various descriptors
