* 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 in the release notes and follow a 1-year
|
|
* deprecation schedule.
