The message printed when a program exits due to an unhandled panic that was recovered and re-raised no longer repeats the text of the panic value.
Previously, a program which panicked with panic("PANIC"), recovered the panic, and then re-panicked with the original value would print:
panic: PANIC [recovered] panic: PANIC
This program will now print:
panic: PANIC [recovered, reraised]
On Linux systems with kernel support for anonymous VMA names (CONFIG_ANON_VMA_NAME), the Go runtime will annotate anonymous memory mappings with context about their purpose. e.g., [anon: Go: heap] for heap memory. This can be disabled with the GODEBUG setting decoratemappings=0.
