* ==================== OTHER CHANGES ====================
-* Unwinding through inlined function calls. By default, stack
- unwinding now makes use of Dwarf3 inlined-unwind information if it
- is available. The practical effect is that inlined calls become
- visible in stack traces. The suppression matching machinery has
- been adjusted accordingly. This is controlled by the new option
- --read-inline-info=yes|no [yes].
-
- In the 3.10.0 beta release(s), inlined unwinding is only enabled for
- Memcheck and Helgrind. It is hoped to enable it for all tools in
- the 3.10.0 final release.
