<ul>

<li><p class="first">Created a completely new Visual Studio 2008 solution from scratch.</p>

</li>
|

<li><p class="first">Added 64 new source files and removed the following deleted files

|

</li>

<li><p class="first">Created a single <span class="filesystem">libtesseract</span> library and removed generation of the

twelve sub-libraries.</p>

<li><p class="first">Used references to <span class="filesystem">leptonica_versionnumbers.vsprops</span> and

<span class="filesystem">tesseract_versionnumbers.vsprops</span> Property Sheets, which define

||
version number “user macros”, in all Visual Studio Projects. These are

also copied to <span class="filesystem">C:\BuildFolder\include</span>, so you can refer to them in

your own projects. By using the new <tt class="docutils literal"><span class="pre">*_VERSION</span></tt> macros, you’ll be

isolated from worrying about version number changes in the library

filenames.</p>
