+### Crash Handling
+
+On Linux, the Swift runtime will now catch program crashes and Swift runtime errors and display a backtrace on the program's output.  The backtracer is out-of-process and includes support for `async` functions.
+
+This feature is also available on macOS, although there it is disabled by default (it can be enabled by setting `SWIFT_BACKTRACE=enable=yes`) and you need to ensure that your program is signed with the `com.apple.security.get-task-allow` entitlement.
+
+A more detailed blog covering this feature will be published soon.

 ### Debugging
 
 In Swift 5.9, we introduced a couple of new features to [LLDB](https://lldb.llvm.org/) and the Swift compiler aimed at making Swift debugging faster and more reliable.
