• Fix compilation on systems without O_CLOEXEC. This affects, e.g., Solaris 10. GitHub issue #326. (Patch by Jiangrz).

• Provide log4cplus::deinitialize() to make the API symmetric (log4cplus::initialize() already exists) and to allow de-/initialization without log4cplus::Initializer instance. GitHub issue #340.

• Deal with register keyword being generated in SWIG based bindings. The keyword is unused and reserved in C++17. Remove use of std::unary_function, it was removed in C++17.

• Add ability to define new log levels using C API. Add reconfiguration API. (Jens Rehsack)

• Add NDCMatchFilter and MDCMatchFilter. (Franck)

log4cplus 2.0.2

• Allow setting thread pool size using new function setThreadPoolSize(). Allow setting the size from log4cplus.properties using log4cplus.threadPoolSize property. Lower initial thread pool size by half to std::thread::hardware_concurrency() threads. GitHub issue #315.

• Fix Autotools based build for MinGW. GitHub issue #317.

• Add configure script option --enable-lto to allow easier LTO builds.

• Optimization of getFormattedTime(). (Alexey Vishtak)

• Introduction of LOG4CPLUS_MACRO_FILE() used in logging macros to allow users to redefine it and consequently hide source file names from their compiled executables and logging output.

log4cplus 2.0.1

• Update to Automake 1.16.1.

• Adjust spi::LoggerFactory to allow custom spi::LoggerImpl. GitHub issue #309.

• Fix MacOS X compilation. GitHub issue #312.

log4cplus 2.0

• CMake improvements: Automate export of includes if building as Cmake sub-module. (Rodion Malinovsky)

• Debian spec file improvements: Use parallel build. Fix installation path on 64bit. (Michal Marek)

• CMake improvements: Use ${CMAKE_INSTALL_LIBDIR} instead of hardcoding lib. (Radek Dostál)

• Experimental Windows 10 ARM support through CMAKE

log4cplus 2.0-RC2

• Avoid copying whole message just to prepend message length in SocketAppender. Instead, use OS specific "gather" socket write.

• Fixed GitHub issue #136.

• FileAppender classes now have TextMode property that can be set to Binary or Text (default) to specify underlying IO stream behavior with respect to end-of-line handling. (Patch by raphaelmarcucci).

• Fixed compilation issues when building log4cplus with Visual Studio and Clang toolchain.

• Fixed various shutdown and initialization related deadlocks and crashes. GitHub issues #251, #253.

• Fixed GitHub issue #243. Single-threaded build with Visual Studio and CMake were not single-threaded.

• Fixed GitHub issue #250. Creating WiX based installer using CPack does not work because of missing license file.

log4cplus 2.0-RC1

• IMPORTANT: Implementation language is now C++11. OS specific implementations have been replaced by C++11 facilities wherever possible. This lowers complexity of the library and improves maintainability but it also brings limitations to when the library can be used. Specifically, the library should not be used before main() is entered and after main() is left. Even more specifically, the library should not be used during global objects construction and destruction.

• log4cplus uses Catch unit testing framework and has unit tests.

• log4cplus supports IPv6.

• Autotools based build system is now partially generated from templates by the Autogen tool.

• Autotools based build system can build both wchar_t and plain char variants at once.
