     <li>The Unicode compiler sees type 'String' as a Unicode string, and 'Char' as a Unicode character. Its 'AnsiString' type hasn't changed and still is an ANSI string. Its 'PChar' type has been renamed to 'PAnsiChar'.</li>
     <li>The Unicode compiler is more strict about correct ';' usage: it no longer accepts certain missing ';' characters.</li>
-    <li>The new RemObjects PascalScript version used by the Unicode compiler supports Unicode, but not for its input source. This means it does use Unicode string types as said, but any literal Unicode characters in the script will be converted to ANSI. This doesn't mean you can't display Unicode strings: you can for example instead use encoded Unicode characters to build Unicode strings (like <tt>S := #$0100 + #$0101 + 'Aa';</tt>), or load the string from a file using <tt>LoadStringsFromFile</tt>, or use a <tt>{cm:...}</tt> constant.</li>
     <li>Some support functions had their prototype changed: some parameters of <tt>CreateOutputMsgMemoPage</tt>, <tt>RegQueryBinaryValue</tt>, <tt>RegWriteBinaryValue</tt>, <tt>OemToCharBuff</tt>, <tt>CharToOemBuff</tt>, <tt>LoadStringFromfile</tt>, <tt>SaveStringToFile</tt>, and <tt>GetMD5OfString</tt> are of type AnsiString now instead of String.</li>
     <li>Added new <tt>SaveStringsToUTF8File</tt>, and <tt>GetMD5OfUnicodeString</tt> support functions.</li>
     <li>Added new 'Int64' type, supported by <tt>IntToStr</tt>. Also added new <tt>StrToInt64</tt>, <tt>StrToInt64Def</tt>, and <tt>GetSpaceOnDisk64</tt> support functions.</li>

 <li>Added new [Setup] section directive: <tt>SignToolRetryDelay</tt>, which defaults to 500. Specifies the number of milliseconds the Setup Compiler should wait before any automatic digital signing retries specified by <tt>SignToolRetryCount</tt>.</li>
 <li>Added new [Setup] section directive: <tt>SignToolMinimumTimeBetween</tt>, which defaults to 0. If not set to 0, specifies the minimum number of milliseconds that should have elapsed between consecutive digital signing actions by the Setup Compiler. For example, if set to 5000 then the Setup Compiler will perform 1 digital signing per 5 seconds at most. Can be used to avoid being rejected by rate limiting timestamp services.</li>
 <li>Added new [Setup] section directive <tt>ArchitecturesAllowed</tt> value: <tt>arm64</tt>. This can be used to not allow Setup to run on Windows 10 on ARM64. Note that Windows 10 on ARM64 only supports 32-bit (x86) binaries and therefore Setup (even in older 3s) will never install in 64-bit mode on Windows 10 on ARM64.</li>
