• 6.0: Optional support for a resizable wizard window.
• 6.0: New optional modern wizard style (example.)
• 6.0: Other changes for a more modern look to Setup, Uninstall, and the Compiler IDE.
• 6.0: New light and dark themes, new toolbar icons and new per-monitor DPI awareness mode for the Compiler IDE (light theme example, dark theme example.)

• 6.0: Support for 64-bit mode on Windows 10 on ARM.
• 6.0: Task dialog support for the [Code] section.
• 6.1: Many improvements to the Compiler IDE including support for editing and debugging of #include files and viewing the preprocessor output directly.
• 6.1: Support for downloading files without using a third-party tool and easily showing the download progress to the user.
• 6.1: Support for per-user fonts if Setup is running on Windows 10 Version 1803 and later.
• 6.2: Graphics modernized, including the automatic use of higher quality images (which were not available before) on higher DPI settings.
• 6.3: Support for UTF-8 encoded files without a BOM.
• 6.3: Support for Arm64 systems improved, and related enhancements.
• 6.3: Many Compiler IDE improvements, including multiple selection support.

• 6.4: Many more Compiler IDE improvements, including match selection, parameter hints, improved autocompletion, section folding, change history and optional Visual Studio Code-style shortcuts.

OS requirements change: Windows Vista and Windows Server 2008 are no longer supported. Windows 7 and Windows Server 2008 R2 are now the minimum supported operating systems. [Setup] section directive MinVersion still defaults to 6.1sp1, so by default Setup will still not run versions of Windows 7 and Windows Server 2008 R2 which have not been updated.
