+* Fixed bug where the message sent by the second process was not received
+  correctly when the message is sent immediately following a connection.
+
+   _Francis Giraldeau_
+
+* Refactored code and implemented shared memory block consistency checks
+  via `qChecksum()` (CRC-16).
+* Explicit `qWarning` and `qCritical` when the library is unable to initialise
+  correctly.
+
+__3.0.10__
+----------
+
+* 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`.
+* Renamed `SingleAppConnectionType` to `ConnectionType`. Added initialization
+  values to all `ConnectionType` enum cases.
+
+    _Jedidiah Buck McCready_
+
+__3.0.9__
+---------
+
+*   Added SingleApplicationPrivate::primaryPid() as a solution to allow
+    bringing the primary window of an application to the foreground on
+    Windows.
+
+    _Eelco van Dam from Peacs BV_
+
+__3.0.8__
+---------
+
+*   Bug fix - changed QApplication::instance() to QCoreApplication::instance()
+
+    _Evgeniy Bazhenov_
+
+__3.0.7a__
+----------
+
+*   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.
+
+__3.0.6a__
+----------
+
+*   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.
+
+    Special thanks to Charles Gunawan.
+
+__3.0.5a__
+----------
+
+*   Fixed a memory leak in the SingleApplicationPrivate destructor.
+
+    _Sergei Moiseev_
+
+__3.0.4a__
+----------
+
+*   Fixed shadow and uninitialised variable warnings.
+
+    _Paul Walmsley_
+
+__3.0.3a__
+----------
+
+*   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.
+
+__3.0.2a__
+----------
+
+*   Fixed bug on Windows when username containing wide characters causes the
+    library to crash.
+
+    _Le Liu_
+
+__3.0.1a__
+----------
+
+*   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
+
+    _Le Liu_
+
+__v3.0a__
+---------
+
+*   Deprecated 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.
+
+__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.
