| |
| 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](/doc/godebug) |
| `decoratemappings=0`. |
