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.

v3.0.1a

• Allows the application path and version to be excluded from the server name
  hash. The following flags were added for this purpose:
• SingleApplication::Mode::ExcludeAppVersion
• SingleApplication::Mode::ExcludeAppPath
• Allow a non elevated process to connect to a local server created by an
  elevated process run by the same user on Windows
• Fixes a problem with upper case letters in paths on Windows

v3.0a

• Depricated secondary instances count.
• Added a sendMessage() method to send a message to the primary instance.
• Added a receivedMessage() signal, emitted when a message is received from a
  secondary instance.
• The SingleApplication constructor's third parameter is now a bool
  specifying if the current instance should be allowed to run as a secondary
  instance if there is already a primary instance.
• The SingleApplication constructor accept a fourth parameter specifying if
  the SingleApplication block should be User-wide or System-wide.
• SingleApplication no longer relies on applicationName and
  organizationName to be set. It instead concatenates all of the following
  data and computes a SHA256 hash which is used as the key of the
  QSharedMemory block and the QLocalServer. Since at least
  applicationFilePath is always present there is no need to explicitly set
  any of the following prior to initialising SingleApplication.
• QCoreApplication::applicationName
• QCoreApplication::applicationVersion
• QCoreApplication::applicationFilePath
• QCoreApplication::organizationName
• QCoreApplication::organizationDomain
• User name or home directory path if in User mode
• The primary instance is no longer notified when a secondary instance had
  been started by default. A Mode flag for this feature exists.
• Added instanceNumber() which represents a unique identifier for each
  secondary instance started. When called from the primary instance will
  return 0.

v2.4

• Stability improvements
• Support for secondary instances.
• The library now recovers safely after the primary process has crashed
  and the shared memory had not been deleted.

v2.3

• Improved pimpl design and inheritance safety.

Vladislav Pyatnichenko

v2.2

• The QAPPLICATION_CLASS macro can now be defined in the file including the
  Single Application header or with a DEFINES+= statement in the project file.
