I.e. they may removed, renamed or changed without warning. + +## Suffixed protocols + +For protocols that have a version suffix, however, we will strive to not break +backwards compatibility without bumping the suffix (renaming the protocol). +E.g.: If your client sees a `zqt_key_v1` global, it can safely bind to it: +the key event will always take the same number of arguments, regardless of +compositor version. + +This is important also within a Qt-only scope if there are multiple versions of +Qt on the system. Consider for instance an application statically linked to Qt +(such as Qt Creator) running against a Qt compositor installed by the distro). +In such cases we don't want the compositor and client to disagree on the +protocol definition. |
