+- [zebra] "no link-detect" is no longer the default.
+
+ The previous release of Quagga always explicitly writes-out the
+ link-detect configuration state. Therefore, to retain current behavior
+ save your config with the prior release before updating.
+
+ Otherwise, review your configuration. Note, most users will generally
+ want to have link-detect enabled, and so can just remove 'no
+ link-detect' from their interface configuration.
+
+ This release also adds a global configuration to specify the default,
+ which can be specified in the zebra configuration as:
+
+ default link-detect (on|off)
+
+ This will then apply to any interface which does not have link-detect
+ explicitly configured.
