    <https://sourceforge.net/tracker/?func=browse&group_id=40830&atid=429073&artgroup=877523>

Version 1.0.3-RC9

  - Tweaked Doxygen docs in comments for more recent Doxygen versions.
  - Fix bug #2632087. Reworked WinSock initialization to fix deadlock
    in WSAStartup() on Windows Vista.

    renaming non-existing files.
  - Fall back to DAILY schedule in DailyRollingFileAppender for
    invalid schedule specification.

Version 1.0.3-RC8

  - Fixed SysLogAppender not being exported out of shared library
    because of missing LOG4CPLUS_EXPORT.
  - Fix bug #1168433. RollingFileAppender does a rename() to rename
    logfile to logfile.1 etc. rename() on Windows will not overwrite
    an existing file so only the first rename works. On Windows
    (only), try to remove existing file first before calling rename().
  - Fix bug #2573222. License issues. Most of log4cplus is covered by
    ASL 1.1. The bits that are not covered by ASL 1.1 are covered by
    two clause BSD licence. Texts of both licences are in LICENCE
    file.

    character '#' and both leading and trailing white space around
    both key and value (e.g. " key = value ") in property files.
  - Fix bug #2594345. Loggingserver and SocketAppender message format
    mismatch.
  - Fixed CMake builds.

    matching properties.
  - Fix compilation for combination of non-threaded and UNICODE
    settings.

Version 1.0.3-RC6

  - Fix Bug #852513 - Reconfiguring a logger does not remove old
    appenders.
  - Changed log4cplus thread helpers to block all signals on POSIX
    platforms to enable their handling in a dedicated thread. (See
    README, chapter Notes for explanation.)
  - Changed thread creation from using CreateThread() to using
    _beginthreadex() to avoid leaking C and C++ runtime memory.
  - Fixed convertIntegerToString() to for negative numbers.
  - Fixed wrong name used in BasicConfigurator for the
    ConsoleAppender.

Version 1.0.3-RC5

  - Add CMakeLists.txt to facilitate compilation of log4cplus on
    Windows with different compilers than just the MSVC8.
  - Fix compilation of Unicode enabled build without working locale.
    (Patch #2429185)

Version 1.0.3-RC4

  - IMPORTANT: log4cplus shared library version has been bumped to
    3. The interfaces have slightly changed and 1.0.3 is not binary
    compatible with 1.0.2.

  - Fix more MSVC compilation problems.
  - Changed log4cplus_static.vcproj to link with DLL C/C++ run time
    (MSVCR80.dll and MSVCP80.dll).
  - Implemented environment variables shadowing by properties and
    recursive properties expansion.
  - Reworked output directories layout of MSVC8 project. Now it
    produces directories of the form
    "log4cplus_{static,dll}.{Release,Debug}{_Unicode,}" and
    "loggingserver.{Release,Debug}{_Unicode,}". The tests directory
    projects still only compile using non-Unicode release and debug
    version of the library.
  - For single-threaded builds, re-use single tostringstream instead
    of using a new one for each LOG4CPLUS_DEBUG() etc. macros.
  - Merge Win32DebugAppender from trunk. (Patches #834925 and #858128)
  - Make configuration of local server for NTEventLogAppender easier
    by allowing empty server parameter string. (Feature Request
    #875935)

Version 1.0.3-RC3

  - Fix Bug #2268760 - Trailing garbage in strings produced by
    Time::getFormattedTime().
  - Fixed compilation of MSVC builds.

Version 1.0.3-RC2

  - Fix Bug #2106949 - Compilation problem with Borland's compiler.
  - Fix Bug #1717320, #1040902, #1040676 - strftime() complains about
    our custom %q and %Q format specifiers with "Invalid format
    directive".
  - Removed safe_auto_ptr.
  - Added --enable-debugging switch to configure script. It disables
    optimization and turns on debugging info generation.
  - Use locale and its codecvt facet in towstring()/tostring()
    implementations when --with-working-locale is defined.
  - Added support for GCC's -fvisibility=hidden flag where available
    together with __attribute__ ((visibility("default"))).

Version 1.0.3-RC1
  - IMPORTANT: VC6 users, VC6 is unsupported. Its standard C++ library
    is too broken. The work around for VC6's std::string has been
    removed from log4cplus code; it actually does not fix the problem,
    it only makes it a little bit less likely to manifest. VC6 project
    files are still distributed with the source but they are broken as
    we have no means to update them. We strongly suggest that you
    either move away from VC6 to some more modern and standard
    conforming compiler (like VC8) or that you use the STLport
    standard C++ library implementation instead of VC6's own.

  - Fixed various compilation issues with MSVC8.
  - Added MSVC8 project files.
  - Fixed compilation with GCC 4.3.
  - Fixed autoconf/automake build machinery so that it is possible to
    build log4cplus in separate directory.

    respectively.

  - Fixed Bug #898646 - Ambiguity between ::yield() and
    thread::yeild() on Solaris.

Version 0.9.10 (August 27 2003)
  - Fixed singled-threaded build compilation issues
  - The DailyRollingFileAppender no longer truncates files
  - The DailyRollingFileAppender now performs a "rollover" on close().  If the

    the other logging macros.  If the old behavior is desired, then the new
    LOG4CPLUS_TRACE_METHOD macro should be used.
  - Modified Appender class to support the "Threshold" property.
  - "localtime" is now the default time in log4cplus.
