If you are still on R3, here is a comparison with current versions (Delphi 12 Athens, 2024–2025):
| Feature | Delphi 2017 R3 | Delphi 12 Athens |
|---------|----------------|------------------|
| Windows 11 support | Basic (Win10 SDK) | Full (Win11 SDK, dark title bars, rounded corners) |
| macOS ARM (M1/M2) | No (Intel only) | Native macOS ARM64 |
| Linux 64-bit | Yes (experimental) | Full production (including GUI apps) |
| Inline variables | No | Yes |
| Custom managed records | No | Yes |
| Android API level | Up to API 26 (Android 8) | API 33+ (Android 13/14) |
| iOS version | Up to iOS 11 | iOS 16/17 |
| Language syntax | Classic Pascal (no [Result] attribute, no for..in with dictionaries directly) | Modern Pascal with [Disable], [Unsafe], volatile |
| IDE memory footprint | ~500 MB | ~1.2 GB (but with faster indexing) |
| Community support | Declining (mostly StackOverflow archives) | Active (Embarcadero forums, YouTube, blogs) | delphi 2017 r3
Verdict: R3 is perfectly adequate for maintaining existing Windows VCL or Android 7–8 apps. But for new development targeting modern OS versions, you need at least Delphi 11 or 12.
