Subject: - New semantics for BASIC_INFO, ADD_HOST and DEL_HOST requests. This will
X-Git-Tag: release-1.0pre3~164
X-Git-Url: https://tinc-vpn.org/git/browse?p=tinc;a=commitdiff_plain;h=18c85caac36f7236454deef11b9eba74328dbd96;hp=e8e7379311ca3bf6e1fdd7d0f477a43e510e2317

- New semantics for BASIC_INFO, ADD_HOST and DEL_HOST requests. This will
  improve connection list consistency, ensures the tree property, and
  allows for recovery from situations where track of connections is lost.
