* New options for stack canaries have been added, providing users with finer control over stack
|
||||
protection. With this change, :kconfig:option:`CONFIG_STACK_CANARIES` no longer enables the
|
||||
compiler option ``-fstack-protector-all``. Users who wish to use this option must now enable
|
||||
:kconfig:option:`CONFIG_STACK_CANARIES_ALL`.
