Software Update: Inno Setup 5.5.6

Jordan Russell Software has released version 5.5.6 of Inno Setup. This program makes it easy to create installation packages for Windows. The program provides the ability to add information to the registry, provides ini files to create shortcuts, and has the ability to compress the installation files. Furthermore, an uninstaller can of course be added and different languages ​​can be selected during installation. Since version 5.5.4, the following changes and improvements have been made:

Changes in version 5.5.6:

• Added the Windows 10 “compatibility” section to the various manifest resources used by Inno Setup. This enables any check for the operating system version to get the real version number (10.0) instead of getting the same version number as it did in Windows 8.1 (6.3).
• Added new [Setup] section directive: SignToolRetryCount, which defaults to 2. Specifies the number of times the Setup Compiler should automatically retry digital signing on any errors.
• Added new [Setup] section directive: SetupMutex. Can be used to prevent Setup from running while Setup is already running.
• Fix: Console-mode compiler (ISCC) change: Renamed /DO and /EO command line parameters to /O- and /O+ to avoid possible conflicts with /D.
• Pascal Scripting change: Unicode Inno Setup: Added new functions VarIsClear and UnpinShellLink.
• Inno Setup Preprocessor (ISPP) change: Added new function ForceDirectories.
• Unicode [Code] based on RemObjects Pascal Script Git commit db0d6f521113a31b34a76aeefd79fb148a9c4bfd.
• Various documentation improvements. Contributed by yoga through GitHub.
• Minor tweaks.

Changes in version 5.5.5:

• /LOG: Now logs INI entries. Also improved logging or icon entries.
• Added new [Setup] section directive: Output, which defaults to yes. If set to no the Setup Compiler will only check the script for errors and skip creating setup files.
• Console-mode compiler (ISCC) changes:
  • Added new command line parameters /DO and /EO. These can be used to disable or enable output, overriding the Output directive.
  • Added new command line parameter /Qp. Can be used to enable quiet compile while still displaying progress. Contributed by KngStr through GitHub.
  • ISCC now automatically specifies any Sign Tools configured using the IDE, eliminating the need to specify these using the /S command line parameter. Also contributed by KngStr through GitHub.
• Pascal Scripting changes:
  • Added new function CurrentSourceFileName, which returns the source file name of the [Files] entry that is currently being processed. The returned name may include constants. Note: Do not attempt to call this function from outside a Check, BeforeInstall or AfterInstall event function belonging to a [Files] entry with the external flag.
  • The already-existing StrToFloat and FloatToStr functions are now documented.
  • Strings and numbers are now highlighted. Based on contribution by maldoinc through GitHub.
  • Unicode Inno Setup: Added new class TStringStream.
• Inno Setup Preprocessor (ISPP) changes:
  • Added new function DeleteFileNow.
  • Added 64-bit support to function ReadReg.
• Added official Scottish Gaelic and Turkish translations.
• Fix: [Setup] section directive UsePreviousLanguage was not working when Setup was running in 64-bit mode.
• Unicode [Code] based on RemObjects Pascal Script Git commit 97eefc260b41ba51328d95b4ed43669f38655720.
• Various documentation improvements. Contributed by yoga through GitHub.
