Changelog
=========
__v3.0a__
--------
* Depricated secondary instances count.
* Added a sendMessage() method to send a message to the primary instance.
* Added a receivedMessage() signal, emmited 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 of 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 uses as the key for the
`QSharedMemory` block and the `QLocalServer`. Since at least
`applicationFilePath` is always present there is no need to explicitly set
any of these 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. An setting 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.
__v2.1__
--------
* A race condition can no longer occur when starting two processes nearly
simultaneously.
Fix issue [#3](https://github.com/itay-grudev/SingleApplication/issues/3)
__v2.0__
--------
* SingleApplication is now being passed a reference to `argc` instead of a
copy.
Fix issue [#1](https://github.com/itay-grudev/SingleApplication/issues/1)
* Improved documentation.
