3.0.11a

  correctly when the message is sent immediately following a connection.

  Francis Giraldeau

  via qChecksum() (CRC-16).

• Explicit qWarning and qCritical when the library is unable to initialise
  correctly.

v3.0.10

• Removed C style casts and eliminated all clang warnings. Fixed instanceId
  reading from only one byte in the message deserialization. Cleaned up
  serialization code using QDataStream. Changed connection type to use
  quint8 enum rather than char.

  values to all ConnectionType enum cases.

  Evgeniy Bazhenov

v3.0.7a

• Fixed compilation error with Mingw32 in MXE thanks to Vitaly Tonkacheyev.
• Removed QMutex used for thread safe behaviour. The implementation now uses
  QCoreApplication::instance() to get an instance to SingleApplication for
  memory deallocation.

v3.0.6a

• Reverted GetUserName API usage on Windows. Fixed bug with missing library.
• Fixed bug in the Calculator example, preventing it's window to be raised
  on Windows.

v3.0.5a

• Fixed a memory leak in the SingleApplicationPrivate destructor.

Sergei Moiseev

v3.0.4a

• Fixed shadow and uninitialised variable warnings.

Paul Walmsley

v3.0.3a

• Removed Microsoft Windows specific code for getting username due to
  multiple problems and compiler differences on Windows platforms. On
  Windows the shared memory block in User mode now includes the user's
  home path (which contains the user's username).
• Explicitly getting absolute path of the user's home directory as on Unix
  a relative path (~) may be returned.

v3.0.2a

• Fixed bug on Windows when username containing wide characters causes the
  library to crash.
