https://go.dev/cl/742580 updated the goroutine label format in tracebacks to only quote the values under some circumstances, and use a more broadly acceptable format. Flip the GODEBUG=tracebacklabels default for go 1.27+ modules. Notably, tracebacklabels is marked as Opaque to avoid some diciness in maintaining a usage metric in signal handlers, etc. (where mutex acquisition may be problematic) Also, update the go 1.27 release notes to call out the new feature.

<!-- CL 742580 -->
|
|
|
|
Tracebacks for modules with `go` directives configuring Go 1.27 or later will now
|
|
include [runtime/pprof](https://pkg.go.dev/runtime/pprof) goroutine labels in
|
|
the header line. This behavior can be disabled with `GODEBUG=tracebacklabels=0`
|
|
(added in [Go 1.26](/doc/godebug#go-126)). This opt-out is expected to be
|
|
kept indefinitely in case goroutine labels acquire sensitive information that
|
|
shouldn't be made available in tracebacks.
