<ul>
<li>Pascal Scripting changes/improvements:
  <ul>
  <li>New <tt>GetUILanguage</tt> support function.</li>
  </ul>
</li>
<li>Compiler IDE: When a file has been modified outside the editor, offer to reload it.</li>
<li><i>Fix:</i> The per-page event functions introduced in 5.0.1 that returned Boolean values didn't work properly.</li>
<li><i>Fix:</i> When the <tt>overwritereadonly</tt> [Files] section flag was used and Setup was unable to remove the read-only attribute from a file (e.g. due to ACL restrictions), it would get stuck in an infinite loop.</li>
<li>Based on RemObjects Pascal Script SVN code revision 947.</li>

<p><a name="5.0.1"></a><span class="ver">5.0.1-beta </span><span class="date">(2004-08-02)</span></p>
<ul>
<li>Compiler IDE: the toolbar now uses a modern looking set of images kindly donated by <a href="http://www.glyfx.com/" target="_blank">glyFX</a>.</li>
<li>Setup/Uninstall can now wait on processes spawned using [Run]/[UninstallRun] entries that have the <tt>shellexec</tt> flag. Combine <tt>shellexec</tt> with either the new <tt>waituntilterminated</tt> flag (the default behavior when <tt>shellexec</tt> <i>isn't</i> specified) or the <tt>waituntilidle</tt> flag.</li>
<li>When Setup is running on Windows NT 4.0, Service Pack 6 is now required. This change shouldn't impact any significant number of users; SP6 was released five years ago, and almost all other programs that still support NT 4.0 nowadays have the same requirement.</li>
<li>Pascal Scripting changes/improvements:
  <ul>
  <li>Added new supported event function <tt>CancelButtonClick</tt>, which is called when the user clicks the Cancel button.</li>
  <li>The prototype of the <tt>CurStepChanged</tt> function has changed, as has the names of the CurStep values passed to it. See the help file for details.</li>
  <li>The names of the values passed to the <tt>CurUninstallStepChanged</tt> function have changed. See the help file for details.</li>
  <li>Per-page event functions are now supported. TWizardPage and its descendants now include these properties: <tt>OnActivate</tt>, <tt>OnBackButtonClick</tt>, <tt>OnCancelButtonClick</tt>, <tt>OnNextButtonClick</tt>, <tt>OnShouldSkipPage</tt>. See the <i>Support Classes Reference</i> topic in the help file for the prototypes of these event functions.</li>
  <li>Replaced the <tt>InstExec</tt> function with a new function named <tt>Exec</tt>. The new function offers the same functionality as the old one, but uses a slightly different prototype. The <tt>WaitUntilTerminated</tt> and <tt>WaitUntilIdle</tt> parameters have been replaced with a single <tt>Wait</tt> parameter.</li>
  <li>Replaced the <tt>InstShellExec</tt> function with a new function named <tt>ShellExec</tt>. The new function adds <tt>Verb</tt> and <tt>Wait</tt> parameters. To get <tt>ShellExec</tt> to behave the same way as the old function, specify <tt>'open'</tt> in the <tt>Verb</tt> parameter and <tt>ewNoWait</tt> in the <tt>Wait</tt> parameter.</li>
  <li>Replaced the <tt>FindFirst</tt> and <tt>FindNext</tt> support functions with new versions that return more information about found files and can handle nested searches. Any existing scripts that called these functions will need updating. There is also a new <tt>FindClose</tt> function that you should call at the end of a find sequence.</li>
  <li>Replaced the confusingly-named <tt>ShouldProcessEntry</tt> support function with new functions named <tt>IsComponentSelected</tt> and <tt>IsTaskSelected</tt>.</li>
  <li>The <tt>Wizard*</tt> support functions now raise exceptions if you call them before the wizard has been initialized, instead of returning empty strings.</li>
  </ul>
</li>
<li>On a file that has the <tt>uninsrestartdelete</tt> flag the containing directory will now also be removed at uninstall time.</li>
<li>When extracting files, Setup now sets just the modification times instead of the creation and modification times.</li>
<li>/LOG improvement: Now logs permission setting on files/directories/registry keys.</li>
<li>The compiler now flags UXTHEME.DLL as an "unsafe" file.</li>
<li>Dropped the obsolete WizModernImage2.bmp and WizModernSmallImage2.bmp images.</li>
<li>Based on RemObjects Pascal Script SVN code revision 945.</li>
<li>The uninstall program's version is now 51.31.0.0.</li>
<li>Minor tweaks.</li>
</ul>

<p><a name="5.0.0"></a><span class="ver">5.0.0-beta </span><span class="date">(2004-07-14)</span></p>
<ul>
<li>The size of compiled installations has decreased by 22-26 KB from Inno Setup 4.2.7, primarily due to the merging of Setup and Uninstall into a single binary.<br /><br /></li>
<li>Pascal Scripting can now be used to customize Uninstall:<br />
  <br />
  <ul>
    <li>Added Uninstall specific event functions <tt>InitializeUninstall</tt>, <tt>DeinitializeUninstall</tt>, <tt>CurUninstallStepChanged</tt> and <tt>UninstallNeedRestart</tt>.</li>
    <li>Added support functions <tt>IsUninstaller</tt> and <tt>UninstallSilent</tt>.</li>
  </ul>
  <br />
  Furthermore, the compiler IDE now supports Uninstall debugging. To debug Uninstall, first run Setup from the IDE, install your application, select <i>Target Uninstall</i> in the <i>Run</i> menu and finally use the debugger functions as normal.<br />
  See the help file and the <i>UninstallCodeExample1.iss</i> example script for more information.<br />
  <br />
</li>
<li>The custom wizard page support has been completely redesigned from the ground up. The new design uses an event-driven model just like standard wizard pages; no longer do you have to write complicated loops to handle sequences of custom pages.<br />
Any existing code utilizing custom wizard pages will need updating; all of the old functions have been replaced. Please see the new <i>Using Custom Wizard Pages</i> topic in the help file and the <i>CodeDlg.iss</i> and <i>CodeClasses.iss</i> example scripts for examples of how to use the new custom wizard page model.<br />
<br />
</li>
<li>Besides space separated lists, you may now also use boolean expressions as <tt>Components</tt>, <tt>Tasks</tt>, <tt>Languages</tt> and <tt>Check</tt> parameters. Supported operators include <tt>not</tt>, <tt>and</tt>, and <tt>or</tt>. For example:
<blockquote><div><tt>
[Components]<br />
Name: a; Description: a<br />
Name: b; Description: b<br />
<br />
[Tasks]<br />
Name: p; Description: a or b; Components: a or b<br />
Name: q; Description: a and b; Components: a and b<br />
Name: r; Description: not a or b; Components: not a or b<br />
Name: s; Description: not (a or b); Components: not (a or b)<br />
Name: t; Description: a or b - old style; Components: a b
</tt></div></blockquote>
</li>
<li>This syntax of function parameters in <tt>Check</tt>, <tt>BeforeInstall</tt> and <tt>AfterInstall</tt> parameters has changed to allow a list of multiple, comma separated, parameters and the use of Integer and Boolean parameter types besides String types. For example, you may now use:
<blockquote><div><tt>
[Files]<br />
Source: MyProg.exe; DestDir: {app}; Check: MyCheck(1, True, 'Some text')<br />
<br />
[Code]<br />
function MyCheck(I: Integer; B: Boolean; S: String): Boolean;<br />
begin<br />
&nbsp;&nbsp;Result := (I &gt; 0) and B and (S &lt;&gt; '');<br />
end;<br />
</tt></div></blockquote>
Also, there's one support function that may be called from within a parameter list: <tt>ExpandConstant</tt>. For example:
<blockquote><div><tt>
[Files]<br />
Source: MyProg.exe; DestDir: {app}; Check: MyCheck(1, True, ExpandConstant('{app}'))<br />
</tt></div></blockquote>
Existing scripts using function parameters will need to be updated.<br />
<br />
</li>
<li>The functions specified by <tt>{code:...}</tt> constants and by <tt>Check</tt>, <tt>BeforeInstall</tt> and <tt>AfterInstall</tt> parameters may now refer to support functions too, for example:
<blockquote><div><tt>
[Components]<br />
Name: adminonly; Description: My Admin Only Component; Check: IsAdminLoggedOn<br />
<br />
[Files]<br />
Source: MyProg.exe; DestDir: {app}; BeforeInstall: Log('About to install MyProg.exe')<br />
Source: MyProg.hlp; DestDir: {app}\Help; Check: DirExists(ExpandConstant('{app}\Help'))<br />
<br />
[INI]<br />
FileName: {app}\MyIni.ini; Section: MySettings; Key: ShortApp; String: {code:GetShortName|{app}}<br />
FileName: {app}\MyIni.ini; Section: MySettings; Key: AppDrive; String: {code:ExtractFileDrive|{app}}
</tt></div></blockquote>
</li>
<li>Wizard-related event functions such as <tt>NextButtonClick</tt> are now called on silent installs as well. In fact, silent installs now function almost identically to non-silent ones with the exception that the Next button is automatically "clicked".</li>
<li>Logging improvements:
  <ul>
    <li>The filenames of programs spawned in the [Run] section are now logged.</li>
    <li>The /LOG parameter is now also supported by Uninstall, which causes Uninstall to create a log file in the user's TEMP directory detailing file uninstallation and [UninstallRun] actions taken during the uninstallation process. This can be a helpful debugging aid. See the <i>Uninstall Command Line Parameters</i> topic in the help file for further details.</li>
  </ul>
</li>
<li>A new <tt>ShouldSkipPage</tt> event function has been added, which replaces <tt>SkipCurPage</tt>. Existing scripts that contain a <tt>SkipCurPage</tt> function will need to be updated. Note that unlike the old <tt>SkipCurPage</tt> event function, the page passed to the <tt>ShouldSkipPage</tt> function is not the current page.</li>
<li>Added support function <tt>Abort</tt>. Calling <tt>Abort</tt> throws an exception to abort the current operation. It does not terminate Setup or Uninstall unless it's still starting up.</li>
<li>When extracting a file, Setup now pre-allocates all of the bytes in the destination file on disk. This allows the system to know what the final size of the file will be before extraction begins, and avoid fragmenting it.</li>
<li>The compiler now fully supports script files that use Unix-style line breaks (LF only).</li>
<li>The Setup section directive <tt>UninstallIconFile</tt> is now deprecated and ignored. As Setup and Uninstall have been merged into a single executable, setting a custom icon for Uninstall is no longer possible.</li>
<li>The Setup section directive <tt>UninstallStyle</tt> is now deprecated and ignored. Only the "modern" uninstaller style is supported now.</li>
<li>Based on RemObjects Pascal Script SVN code revision 933.</li>
<li>The uninstall program's version is now 51.30.0.0.</li>
<li>A very large number of minor tweaks.</li>
<li>This version is derived from Inno Setup 4.2.7, and therefore includes all of the features and fixes from that version.</li>
</ul>
