The documentation for wayland-server.h says: > Use of this header file is discouraged. Prefer including > wayland-server-core.h instead, which does not include the server protocol > header and as such only defines the library PI, excluding the deprecated API > below. Replacing wayland-server.h with wayland-server-core.h allows us to drop the WL_HIDE_DEPRECATED declaration.

/*
|
|
* This is a stable interface of wlroots. Future changes will be limited to:
|
|
*
|
|
* - New functions
|
|
* - New struct members
|
|
* - New enum members
|
|
*
|
|
* Note that wlroots does not make an ABI compatibility promise - in the future,
|
|
* the layout and size of structs used by wlroots may change, requiring code
|
|
* depending on this header to be recompiled (but not edited).
|
|
*
|
|
* Breaking changes are announced by email and follow a 1-year deprecation
|
|
* schedule. Send an email to ~sircmpwn/wlroots-announce+subscribe@lists.sr.ht
|
|
* to receive these announcements.
