[crimaniak]

## What's New (since 2017)

hover documentation, and go-to-definition via LSP
* dub.sdl and dub.recipe support — projects using SDL or recipe 
manifest formats are now recognized
* Named argument parsing — DIP1040 / DMD 2.103+ named arguments 
parsed correctly
* LDC detection on Ubuntu/Debian (/usr/lib/ldc/\<arch>/include/d/)
* Auto-detected compiler & stdlib paths shown in the Language 
Server settings page
* Security fixes — gson (CVE-2022-25647) and junit 
(CVE-2020-15250) updated
* Modern build — Eclipse 2025-03, Tycho 4.0.13, Java 21 
toolchain, GitHub Actions CI/CD
