Subtitle Edit 4 is now in bug-fix-only mode.
I don’t have time to actively maintain both SE4 and develop the new SE5, so focus will be on the SE5 rewrite.

---

SE4 (Current Version)

• Built with WinForms on .NET Framework 4
• Will continue to receive bug fixes and third-party component updates for some time
• Still stable and recommended for production use

---

SE5 (Next Generation)

• UI rewritten using Avalonia UI and .NET 10
• Designed to be cross-platform (Windows, macOS, and Linux)
• Aims for a modern, maintainable architecture

---

Why the Rewrite?

• Modern tech stack for better performance, maintainability, and developer contributions
• True cross-platform support
• Future-proofing as WinForms/.NET 4 become increasingly hard to maintain — especially on Linux

---

Current Status

SE5 is not ready for beta testing yet, but early preview builds are available here:

Do you have approximate ETA for SE5 beta?

[niksedk]

Hard to say, hopefully around February.
The TODO list is mainly "Batch convert", OCR, ASSA, and translation stuff - and bug fixes.

SE-Avalonia looks nice on my 4K desktop, sharp and clean. Menu and Settings are well organized. For improvement, users could give feedback when they use it. To me it looks quite promising and I'm really looking forwards to a beta version with all those features on V4.

"UI rewritten using Avalonia UI", but will it also work via Web browser? "Cross-platform" sounds nice, but it would be way better if it also supports client/server. If Im too late with my request, maybe at least the UI can be decoupled? See #10045
