<p><a name="5.0.6"></a><span class="ver">5.0.6 </span><span class="date">(2004-12-24)</span></p>
<ul>
<li>This version introduces a new Inno Setup logo, new icons for the Inno Setup IDE, and new wizard images for the Inno Setup installer, created by <a href="http://www.glyfx.com/" target="_blank">glyFX</a>.</li>
<li>New [Files] section flag: <tt>createallsubdirs</tt>. By default the compiler skips empty directories when it recurses subdirectories searching for the <tt>Source</tt> filename/wildcard. The <tt>createallsubdirs</tt> flag causes these directories to be created at install time (just like if you created [Dirs] entries for them). Must be combined with <tt>recursesubdirs</tt>.</li>
<li>New flag supported by the [Components] and [Tasks] sections: <tt>checkablealone</tt>. This flag specifies that the component/task can be checked when none of its children are. By default, if no <tt>Components</tt>/<tt>Tasks</tt> parameter directly references the component/task, unchecking all of the component/task's children will cause the component/task to become unchecked.</li>
<li>Pascal Scripting changes/improvements:
<ul>
<li>An <tt>AddEx</tt> function has been added to <tt>TInputOptionWizardPage</tt> to allow the addition of subitems.</li>
<li>Various properties have been added to the <tt>TInput...WizardPage</tt> classes to allow access to the wizard page controls.</li>
<li>Event function <tt>NeedRestart</tt> is now called near the end of the installation process instead of at the beginning.</li>
<li>In DLL function imports, new options 'setuponly' and 'uninstallonly' are supported, which cause a DLL to be loaded only when the script is running from Setup or Uninstall, respectively.</li>
<li>Added new <tt>UnloadDLL</tt> and <tt>GetShellFolderByCSIDL</tt> functions.</li>
</ul>
</li>
<li>/LOG changes:
<ul>
<li>No longer (automatically) logs when the event functions <tt>InitializeSetup</tt>, <tt>InitializeWizard</tt>, <tt>GetCustomSetupExitCode</tt>, and <tt>DeinitializeSetup</tt> are called successfully -- only if they raise exceptions, and in the case of <tt>InitializeSetup</tt>, if False is returned.</li>
<li>Now logs the function name when the <tt>NeedRestart</tt>, <tt>RegisterPreviousData</tt>, <tt>InitializeUninstall</tt>, <tt>DeinitializeUninstall</tt>, <tt>CurUninstallStepChanged</tt>, and <tt>UninstallNeedRestart</tt> event functions raise exceptions.</li>
</ul>
</li>
<li>Compiler IDE changes/improvements:
<ul>
<li>New "Debug Output" view that shows log messages from Setup/Uninstall in real time. (These are the same messages seen in the log file produced when Setup/Uninstall is run with the /LOG switch.)</li>
<li>New <i>Pause on exceptions</i> option (accessible via <i>View | Options</i>). Unchecking this will prevent the debugger from pausing when an exception is raised from [Code].</li>
<li>Now preserves the position of the splitter when you close the IDE.</li>
</ul>
</li>
<li>Console-mode compiler (ISCC.exe): A new /F switch is supported which can be used to specify a new output filename, overriding any <tt>OutputBaseFilename</tt> setting in the script.</li>
<li>Improved Setup load time on installations containing hundreds of components at varying levels.</li>
<li>Updated zlib library to version 1.2.2.</li>
<li><i>Fix:</i> When multiple patterns were specified in a [Files] section <tt>Excludes</tt> parameter, patterns that included backslashes were handled incorrectly.</li>
<li><i>Fix:</i> [Components]: If you had two child radio buttons and one had children of its own, then unchecking & rechecking the top-level item would cause both radio buttons to be checked.</li>
<li>Based on RemObjects Pascal Script SVN code revision 1000.</li>
<li>Minor tweaks.</li>
</ul>
<p><a name="5.0.5"></a><span class="ver">5.0.5-beta </span><span class="date">(2004-11-14)</span></p>
<ul>
<li>New [Setup] section directive: <tt>OutputManifestFile</tt>. When set, the compiler will create a text file detailing information about the files compiled into Setup.</li>
<li>Pascal Scripting changes/improvements:
<ul>
<li>Added new exception-related functions: <tt>GetExceptionMessage</tt>, <tt>RaiseException</tt>, and <tt>ShowExceptionMessage</tt>.</li>
<li>The <tt>ExtractTemporaryFile</tt> support function now raises an exception with a descriptive error message when it fails, instead of returning a Boolean indicating success/failure.</li>
<li><tt>GetSpaceOnDisk</tt>: Added new <tt>InMegabytes</tt> parameter. By setting it to False, you can get figures in bytes (capped at 2 GB-1).</li>
<li><tt>RegWriteMultiStringValue</tt>: When writing values, it now appends two null terminators automatically, like [Registry] does when writing <tt>multisz</tt>-type values.</li>
</ul>
</li>
<li>Console-mode compiler (ISCC.exe) improvements:
<ul>
<li>A new /O switch is supported which can be used to specify a new output path, overriding any <tt>OutputDir</tt> setting in the script.</li>
<li>A new /Q switch is supported which causes it to compile quietly, printing only error messages.</li>
<li>Error messages are now written to standard error instead of standard output.<br /><i>Note:</i> If you were previously redirecting all compiler messages to a file using <tt>>filename</tt> you will now need to use <tt>>filename 2>&1</tt> to capture standard error as well. If you wish to redirect only standard error, use <tt>2>filename</tt>.</li>
</ul>
</li>
<li>When <tt>ChangesAssociations=yes</tt> and/or <tt>ChangesEnvironment=yes</tt> are used, it now notifies Windows of the changes <i>after</i> any [Run] section entries are processed and the <tt>CurStepChanged(ssPostInstall)</tt> event function is called.</li>
<li>Reverted one of the small image placement changes in 5.0.4: horizontally centering has been restored.</li>
<li><i>Fix:</i> When the <tt>ExpandConstant</tt> support function was called at uninstall time, <tt>{common*}</tt> constants always mapped to their <tt>{user*}</tt> equivalents even if the user had administrative privileges.</li>
<li><i>Fix:</i> <tt>ChangesAssociations=yes</tt> worked on Windows NT 4.0 and 2000 but had no effect on Windows XP.</li>
<li><i>Fix:</i> When writing empty REG_MULTI_SZ values, it should only append 1 null terminator, not 2.</li>
<li>Based on RemObjects Pascal Script SVN code revision 983.</li>
<li>The uninstall program's version is now 51.34.0.0.</li>
<li>Minor tweaks.</li>
</ul>
<p><a name="5.0.4"></a><span class="ver">5.0.4-beta </span><span class="date">(2004-10-06)</span></p>
<ul>
<li>New [Setup] section directive: <tt>ChangesEnvironment</tt>. When set to <tt>yes</tt>, at the end of the installation Setup will notify other running applications (notably Windows Explorer) that they should reload their environment variables from the registry.</li>
<li>Pascal Scripting changes/improvements:
<ul>
<li>The support functions <tt>CreateCustomForm</tt>, <tt>ScaleX</tt>, and <tt>ScaleY</tt> may now be called at uninstall time.</li>
<li><tt>TRichEditViewer</tt> support class improvement: The <tt>Color</tt> property is now respected.</li>
</ul>
</li>
<li>/LOG improvements:
<ul>
<li>It's now possible to specify a fixed path/filename to use for the log file via /LOG="<i>filename</i>".</li>
<li>Now logs when various event functions are called, and in the case of <tt>InitializeSetup</tt> it also logs the return value of the function.</li>
<li>Now logs when DLL/OCX/type library registration fails, even if the <tt>noregerror</tt> flag is specified.</li>
</ul>
</li>
<li>Stretching of the small wizard image (specified by <tt>WizardSmallImage</tt>) now only occurs if the image is larger than the default size, or if the user is running larger-than-normal fonts. Previously, it always attempted to stretch the image.</li>
<li>The <tt>WizardSmallImageBackColor</tt> [Setup] section directive is now deprecated and ignored. Any unused space around the small wizard image is now filled with the standard window color (usually white).</li>
<li>Relative paths specified in [Icons] section entries are now converted into absolute paths automatically.</li>
<li><i>Fix:</i> On Windows XP, folder shortcuts (which were introduced in 5.0.3-beta) showed ".lnk" at the end of them.</li>
<li>Based on RemObjects Pascal Script SVN code revision 960.</li>
<li>The uninstall program's version is now 51.33.0.0.</li>
<li>Minor tweaks.</li>
</ul>
<p><a name="5.0.3"></a><span class="ver">5.0.3-beta </span><span class="date">(2004-08-16)</span></p>
<ul>
<li>New supported [Files] section flag <tt>uninsnosharedfileprompt</tt>, which tells the uninstaller to automatically remove the shared file when its reference count reaches zero instead of asking the user. Must be combined with the <tt>sharedfile</tt> flag to have an effect.</li>
<li>New supported [Icons] section flag <tt>foldershortcut</tt>, which creates a special type of shortcut known as a "Folder Shortcut". Normally, when a shortcut to a folder is present on the Start Menu, clicking the item causes a separate Explorer window to open showing the target folder's contents. In contrast, a "folder shortcut" will show the contents of the target folder as a submenu instead of opening a separate window.<br />
Folder shortcuts are only supported by Windows 2000, Me, and later. On earlier versions of Windows, Setup will fall back to creating a normal shortcut when this flag is used.</li>
<li>Pascal Scripting changes/improvements:
<ul>
<li>The return value of the <tt>CreateShellLink</tt> function has changed from a Boolean to a String. Now, any failure results in an exception being raised.</li>
</ul>
</li>
<li>The uninstaller is now capable of removing directories that have the read-only attribute set. (No special flags are needed; this is the default behavior.)</li>
<li>Based on RemObjects Pascal Script SVN code revision 948.</li>
<li>The uninstall program's version is now 51.32.0.0.</li>
<li>Minor tweaks.</li>
