Other changes include a generally available goroutine leak profiler, faster small memory allocations (~1% overall improvement), removal of bzr version control support in the go command, permanent removal of several GODEBUG settings (asynctimerchan, gotypesalias, and multiple crypto/tls settings), macOS 13 Ventura as the new minimum requirement, and ELFv2 ABI support for big-endian PowerPC on Linux. ## Full article daily.dev links to this article rather than hosting it.
