[!WARNING] Deprecated methods will be removed in glog 0.8.0. Please make sure to update your code.

• google::LogMessage::getMessageTime has been superseded by google::LogMessage::time.
• google::LogMessageTime::timestamp has been superseded by google::LogMessageTime::when.
• google::LogMessageTime::gmtoff has been superseded by google::LogMessageTime::gmtoffset.
• google::EnableLogCleaner(unsigned) has been superseded by google::EnableLogCleaner(std::chrono::minutes).
• google::LogSink::send accepting std::tm (deprecated since glog 0.6.0) has been superseded by google::LogSink::send to accept google::LogMessageTime instead.
• google::LogMessageInfo and the custom prefix callback accepting this type have been superseded by google::LogMessage. To customize the log line prefix use the google::InstallPrefixFormatter function instead of the google::InitGoogleLogging overload.

Further changes

• google::LogSeverity has been converted to an unscoped enum. This can result in compilation issues if implicit conversion between an int and google::LogSeverity was erroneously assumed.
• By default, CMake no longer generates the undocumented and untested pkg-config files. The support is now opt in which requires the CMake option WITH_PKGCONFIG to be explicitly set to ON.
