<!-- go.dev/issue/65316 -->
The `trace` tool now better tolerates partially broken traces by attempting to
recover what trace data it can. This functionality is particularly helpful when
viewing a trace that was collected during a program crash, since the trace data
leading up to the crash will now [be recoverable](/issue/65319) under most
circumstances.

The runtime now explicitly flushes trace data when a program crashes due to an
uncaught panic. This means that more complete trace data will be available in a
trace if the program crashes while tracing is active.
