* [Setup] section directives VersionInfoProductVersion now sets the binary product version value instead of the textual product version value.
* Added new [Setup] section directive: VersionInfoProductTextVersion, which sets the textual product version value. Its default value is VersionInfoProductVersion if set, else VersionInfoVersion.
* [Setup] section directives DisableDirPage and DisableProgramGroupPage can now be set to auto. If they are, at startup Setup will look in the registry to see if the same application is already installed, and if so, it will hide the pages automatically.
* Pascal Scripting changes:
o WizardForm.PrevAppDir is now available and returns the directory of the previous installation. Returns an empty string if there's no previous installation or if UsePreviousAppDir is set to no or if Uninstallable was previously set to no.
o While running any PrepareToInstall event function Setup now displays the Preparing to Install wizard page instead of the Ready to Install page and disables itself.
* Added the Windows 7 "compatibility" section to the various manifest resources used by Inno Setup.
* Documentation improvements.
