<!-- --------------------------------------------- -->
<p>
Changes introduced in 3.4.2 were mostly to get networking
code working in mingw environment. The naming collition
of ASSA::ERROR logging mask was resolved by renaming it to
ASSA::ASSAERR.
</p>
<p>
<table border="1" frame="border" cellpadding="3" cellspacing="1">
<caption>Logging Mask name change</caption>
<tr bgcolor="#E9967A">
<th>3.4.1</th>
<th>3.4.2</th>
</tr>
<tr>
<td>ASSA::ERROR</td>
<td>ASSA::ASSAERR</td>
</tr>
</table>
</p>
<p>It was discovered by trial-and-error
that you cannot set Socket into <b>blocking</b> mode.
Instead, a Socket can either have O_NONBLOCK flag set or cleared.
Therefore, <b>Socket::blocking</b> option was removed.
Use <tt>Socket::turnOptionOn (nonblocking)</tt> and
<tt>Socket::turnOptionOff (nonblocking)</tt> respectively
to manipulate the flag.

<p>
The interface changes intruduced in version 3.4.0 break backward
compatability with the previous versions of the library. This is
mostly due to the *feature* of cygwin development tools that fail
to differentiate between <tt>Assert.h</tt> in your build directory and
system-wide <tt>/usr/include/assert.h</tt> file.
</p>
<p>The file <tt>assa/Assert.h</tt>, therefore, has been renamed
to <tt>assa/Assure.h</tt>.
</p>

<!-- --------------------------------------------- -->
<p>
Also, a whole lot of function and data member names has been
*normalized* in two classes, <tt>GenServer</tt> and <tt>Singleton</tt>
in order to improve code readability and consistency. The complete
list of changes is listed in the tables below.

<!-- --------------------------------------------- -->
<p>
In case of <tt>stopServer()</tt> member function, the event processing
loop typical for ver. 3.3.x or prior should be modified in the
following fashion:
</p>
<pre>
// ver. 3.3.x and prior
while (!stopServer()) {
m_reactor.waitForEvents ();
}
// ver. 3.4.x
while (service_is_active ()) {
m_reactor.waitForEvents ();
}
</pre>
<hr></hr>
<!-- --------------------------------------------- -->
<p>
To accommodate a certain way of initializing applications written
with <tt>libassa</tt>, the way <tt>BOOL</tt> command-line arguments
are parsed and interpreted was changed. In the previous versions,
a whole group of options was used as flags. For example,
<tt>--daemon</tt> option was used to tell <tt>libassa</tt> to deamonize
the process. This has been changed to <tt>--daemon=BOOL</tt> format
where <font color="brown">BOOL</font> is either "<tt>yes</tt>" or
"<tt>no</tt>" (any other combinations are invalid and would result
in the value being interpreted as "<tt>no</tt>").
</p>
<p>
<tt>libassa</tt> still supports flag options (i.e. <tt>--help</tt>),
but they should be rather an exception then a commonplace practice.
</p>
<p>
This change is driven by the desire to give an application writer
the fullest level of initialization control. The order of initialization
is as follows:
<ol>
<li>
The command-line arguments are assigned values in the
constructor of the class derived from <tt>GenServer</tt> class.
</li>
<li>
The arguments are later can be overwritten by the INI configuration
file using a new function,
<font color="brown">CmdLineOpts::parse_config_file(IniFile&)</font>
introduced by this release.
</li>
<li>
At last, the arguments can be changed by the values given
on a command-line.
</li>
</ol>
</p>
<p>
<b>NOTE:</b> This change has sudden sude-effect. If you forget to
adjust the way you pass your old *flag* command-line argument to your
program, the value assigned to it would be "<tt>no</tt>" by default!
So, say what you mean with "<tt>yes</tt>"!
