 # Changelog
 
+## 0.5.0
+
+### New Features
+
+- **Java debugging via DAP** — launch and attach to JVM programs using Microsoft's `java-debug.core` adapter
+  - `dbg launch --runtime java Hello.java` — launch with breakpoints, stepping, variable inspection, eval
+  - `dbg attach localhost:5005 --runtime java` — attach to a running JVM via JDWP
+  - `dbg install java` — managed install (~3.5MB from Maven Central, compiled locally)
+  - Conditional breakpoints, exception pause, function breakpoints (registration only without JDT)
+  - Auto-detect `mvn`, `gradle`, `gradlew`, `mvnw`, `mvnDebug` as Java runtimes
+
+### Internal
+
+- **Adapter installer registry** — `src/dap/adapters/` with `AdapterInstaller` interface; adding a new adapter = one file + one registry entry
+- **DapSession runtime strategy pattern** — replaced if/else chain with `DapRuntimeConfig` per runtime for launch args, attach parsing, and adapter resolution
+- **Build-time asset bundling** — Java adapter sources tarball generated by `build.ts`, bundled as Bun file asset, lazy-imported at install time
+- Extracted lldb installer from monolithic `install.ts` into `adapters/lldb.ts`
+- Fixed lldb installer bug: liblldb extraction from already-deleted tarball
+- `Bun.$` shell syntax replaces `Bun.spawnSync` in adapter installers
+- `Bun.which()` replaces `which` shell command for adapter resolution
+- `path.delimiter` for cross-platform classpath separator
+- Attach-mode disconnect preserves debuggee (`terminateDebuggee: false`)
