What's new in this version:

# Windows 7 change:

- Added new [Setup] section directive: UninstallDisplaySize. On Windows 7 and newer, Setup uses this directive to set the EstimatedSize value in the Uninstall registry key when possible since the Windows 7 Add/Remove Programs Control Panel (called Program and Features) no longer automatically calculates it. If an UninstallDisplaySize is not set, Setup estimates the size itself by taking the size of all files installed and adding any ExtraDiskSpaceRequired values set. Note: Windows 7 only supports the display of values smaller than 4 GB.

# Pascal Scripting now supports IUnknown based COM. Previously it only supported IDispatch based COM but a growing number of Windows API functions are COM based without implementing the IDispatch interface, and you can now use these as well. See the new CodeAutomation2.iss example script for an example. Note: this is only supported by Unicode Inno Setup at the moment, because of Delphi 2's limitations (Delphi 2 is used to compile Non Unicode Inno Setup):

- Added StringToGUID, CreateComObject, and OleCheck support functions.
- Added HResult, TGUID, TCLSID, and TIID support types.

# The compiler no longer allows a single LanguageCodePage directive to be applied to multiple languages at once. If you were using this to force Non Unicode Setup to allow the user to select any language regardless of the system code page, set [Setup] section directive ShowUndisplayableLanguages to yes instead.

# Added new CodePrepareToInstall.iss example script.

# Fix: Unicode Pascal scripting: passing a very long string to Format caused an error.

# Minor tweaks.
