 * LLDB now supports RISC-V 32-bit ELF core files.
+=======
+* LLDB now supports siginfo descriptions for user-space signals. User space
+  signals will now have descriptions describing the method and sender.

+    stop reason = SIGSEGV: sent by tkill system call (sender pid=649752, uid=2667987)
+  ```
+* ELF Cores can now have their siginfo structures inspected using `thread siginfo`.
