1.1 KiB
Compiler
The compiler already disallowed defining new methods with receiver types that were cgo-generated, but it was possible to circumvent that restriction via an alias type. Go 1.24 now always reports an error if a receiver denotes a cgo-generated type, whether directly or indirectly (through an alias type).
Assembler
Linker
The linker now generates a GNU build ID (the ELF NT_GNU_BUILD_ID note) on ELF platforms
and a UUID (the Mach-O LC_UUID load command) on macOS by default.
The build ID or UUID is derived from the Go build ID.
It can be disabled by the -B none linker flag, or overridden by the -B 0xNNNN linker
flag with a user-specified hexadecimal value.
Bootstrap
As mentioned in the Go 1.22 release notes, Go 1.24 now requires Go 1.22.6 or later for bootstrap. We expect that Go 1.26 will require a point release of Go 1.24 or later for bootstrap.
