+<p><strong>[Changed in 2.5.3.x]</strong></p>
+<p>wx.TaskbarIcon now works on all three platforms, although for wxGTK it
+depends on support from the Window Manager. On OS X the icon replaces
+the application's icon on the dock and when you right click on it the
+app's default popup menu is merged with the wx.TaskBarIcon's menu.
+Because of how it is implemented on the Mac using the Dock most of the
+TaskBarIcon events will _not_ be emitted on that platform, but since
+98% of the time you simply want to display an icon and have a popup
+menu it shouldn't be much of a problem. You can still use the other
+events on the other platforms, you'll just want to be sure that you
+can do everything you want via the menu too.</p>
+<p>Since popping up a menu is the most common thing to do with a
+TaskBarIcon the class has some new built in functionality to
+facilitate that. To use the TaskBarIcon in this new way, simply
+derive a new class from TaskBarIcon and implement a CreatePopupMenu
+method that creates and returns the menu. That's all there is to it,
+besides binding event handlers for the menu items of course. Take a
+look at the DemoTaskBarIcon class in the demo/Main.py module for an
+example.</p>
+<p><strong>NOTE</strong>: Unfortunately due to being able to support virtualizing
+CreatePopupMenu the C++ TaskBarIcon instance now holds a reference to
+the Python instance, and so you will need to explicitly Destroy() your
+TaskBarIcon instance when you are done with it. (Like you do with
+wx.Dialogs.) If you don't destroy it then wxWidgets will assume that
+you want the app to keep running with just the icon in the task bar
+and the MainLoop will not exit.</p>

+<p><strong>[Changed in 2.5.3.x]</strong></p>
+<p>Starting with 2.5.3.0 the Unicode versions of wxPython will no longer
+have a 'u' appended to the fourth component of the version number.
+Please check for the presence of "unicode" in the <cite>wx.PlatformInfo</cite>
+tuple instead. (This tuple of strings has been available since the
+first 2.5 version.) For example:</p>
+<pre class="literal-block">
+if "unicode" in wx.PlatformInfo:
+ # do whatever
+ ...
+</pre>

+<div class="section" id="multi-version-installs">
+<h1><a name="multi-version-installs">Multi-Version Installs</a></h1>
+<p><strong>[Changed in 2.5.3.x]</strong></p>
+<p>Starting with 2.5.3.0 the wx and wxPython package directories will be
+installed in a subdirectory of the site-packages directory, instead of
+directly in site-packages. This is done to help facilitate having
+multiple versions of wxPython installed side-by-side. Why would you
+want to do this? One possible scenario is you have an app that
+requires wxPython 2.4 but you want to use the newest 2.5 to do your
+own development with. Or perhaps you want to be able to test your app
+with several different versions of wxPython to ensure compatibility.
+Before everyone panics, rest asured that if you only install one
+version of wxPython then you should notice no difference in how things
+work.</p>
+<p>In addition to installing wxPython into a "versioned" subdirectory of
+site-packages, a file named <cite>wx.pth</cite> is optionally installed that will
+contain the name of the versioned subdirectory. This will cause that
+subdirectory to be automatically added to the sys.path and so doing an
+"import wx" will find the package in the subdirectory like it would
+have if it was still located directly in site-packages. I say
+"optionally" above because that is how you can control which install
+of wxPython is the default one. Which ever version installs the
+wx.pth file will be the one that is imported with a plain "import wx"
+statement. Of course you can always manipulate that by editing the
+wx.pth file, or by setting PYTHONPATH in the environment, or by the
+method described in the next paragraph.</p>
+<p>Finally, a new module named wxversion.py is installed to the
+site-packages directory. It can be used to manipulate the sys.path at
+runtime so your applications can select which version of wxPython they
+would like to to have imported. You use it like this:</p>
+<pre class="literal-block">
+import wxversion
+wxversion.select("2.4")
+import wx
+</pre>
+<p>Then even though a 2.5 version of wxPython may be the default the
+application that does the above the first time that wx is imported
+will actually get a 2.4 version. <strong>NOTE:</strong> There isn't actually a 2.4
+version of wxPython that supports this, but there will be.</p>
