Provisional release notes below.

wlroots 0.13.0 includes the following breaking changes.

Breaking changes for compositors

These changes can affect most compositors.

• Replace wlr_key_state with wl_keyboard_key_state (Replace wlr_key_state with wl_keyboard_key_state #2446):
  enum wlr_key_state has been replaced with enum wl_keyboard_key_state
• Use uint32_t in wlr_renderer_begin signature (Use uint32_t in wlr_renderer_begin signature #2433)
• Remove unneeded includes from wlr_input_device.h (Remove unneeded includes from wlr_input_device.h #2470)
• Renderer v6, incremental version (Renderer v6, incremental version #2240): some implicit assumptions about
  wlr_renderer's EGL context no longer hold true. Compositors not using EGL
  directly shouldn't be affected.
  • wlroots' framebuffer no longer is the EGL default framebuffer
  • wlroots' framebuffer no longer has a depth attachment
• Remove wlr_create_renderer_func_t (Remove wlr_create_renderer_func_t #2561)
  • wlr_backend_autocreate, wlr_drm_backend_create, wlr_headless_backend_create, wlr_wl_backend_create, wlr_x11_backend_create no longer take a wlr_renderer_create_func_t parameter
  • The wlr_renderer_create_func_t type has been removed
• backend/noop: listen to display destroy and destroy the backend (backend/noop: listen to display destroy and destroy the backend #2583):
  the noop backend should no longer be manually destroyed after the wl_display
• xdg shell: remove wlr_xdg_surface_for_each_popup (xdg shell: remove wlr_xdg_surface_for_each_popup()  #2610)
  wlr_xdg_surface_for_each_popup has been removed, use
  wlr_xdg_surface_for_each_popup_surface instead.
• layer shell: rename popup iterator for consistency (layer shell: rename popup iterator for consistency #2617):
  wlr_layer_surface_v1_for_each_popup has been renamed to
  wlr_layer_surface_v1_for_each_popup_surface.
• Keyboard interactivity options (Keyboard interactivity options #2555):
  wlr_layer_surface_v1_state.keyboard_interactivity has now the type
  enum zwlr_layer_surface_v1_keyboard_interactivity to reflect protocol changes.
• output: remove scale/transform events (output: remove scale/transform events #2631): the scale and transform
  output events have been removed, compositors should use the commit event instead.
• output: send commit event after pending state is cleared (output: send commit event after pending state is cleared #2630):
  compositors can no longer read the to-be-committed state from wlr_output.pending in an output commit event handler. Instead, use the current state and wlr_output_event_commit.
• render/wlr_texture: clamp texture coordinates to edge by default (render/wlr_texture: clamp texture coordinates to edge by default #2476):
  the GLES2 renderer no longer wraps textures with GL_REPEAT. If you want to repeat a texture, manually change wlroots' default via glTexParameteri.
• text_input_v3: correct typo in enum field (text_input_v3: correct typo in enum field #2735): WLR_TEXT_INPUT_v3_FEATURE_CONTENT_TYPE has been renamed to WLR_TEXT_INPUT_V3_FEATURE_CONTENT_TYPE.
• Stop using wl_shm_format (Stop using wl_shm_format #2744): the renderer functions take DRM_FORMAT_* values instead of WL_SHM_FORMAT_*. Make sure you don't have any remaining WL_SHM_FORMAT_* enum value in your compositor.
  • wlr_renderer_read_pixels now takes a DRM format code instead of an enum wl_shm_format
  • wlr_renderer_get_shm_texture_formats now returns DRM format codes instead of an enum wl_shm_format
  • wlr_renderer_read_pixels now takes a DRM format code instead of an enum wl_shm_format
  • wlr_output_preferred_read_format now returns a DRM format code instead of an enum wl_shm_format

Breaking changes for custom backends and renderers

These changes are unlikely to affect compositors that don't have a custom
backend or renderer.

• render: add wlr_renderer_get_dmabuf_render_formats (render: add wlr_renderer_get_dmabuf_render_formats #2483)
  • wlr_egl_get_dmabuf_formats has been renamed to wlr_egl_get_dmabuf_texture_formats
  • wlr_renderer_get_formats has been renamed to wlr_renderer_get_shm_texture_formats
  • wlr_renderer_get_dmabuf_formats has been renamed to wlr_renderer_get_dmabuf_texture_formats
  • wlr_renderer_format_supported has been removed (instead, use wlr_renderer_get_shm_texture_formats)
• backend/session: misc. refactoring, replace CanGraphical with udev (backend/session: misc. refactoring, replace CanGraphical with udev #2465)
  • wlr_drm_backend_create takes a wlr_device instead of a DRM FD
  • wlr_device.signal has been replaced by wlr_device.events.change
  • wlr_session.session_signal has been replaced by wlr_session.events.active
  • wlr_session_open_file and wlr_session_close_file now take a wlr_device instead of a FD
  • wlr_session_find_gpus now fills an array of wlr_device pointers instead of an array of FDs
• backend/session: allow wlr_session_find_gpus to return an error (backend/session: allow wlr_session_find_gpus to return an error #2578):
  wlr_session_find_gpus now returns a ssize_t instead of a size_t
• render/egl: remove unused features, introduce create/destroy (render/egl: remove unused features, introduce create/destroy #2623)
  • The EGLint visual_id parameter of wlr_egl_init has been removed.
  • wlr_egl_swap_buffers has been removed.
  • wlr_egl_init and wlr_egl_finish have been replaced with wlr_egl_create and wlr_egl_destroy.
  • wlr_egl_make_current no longer takes the arguments EGLSurface surface, int *buffer_age.
• Remove wlr_egl from backends (Remove wlr_egl from backends #2602): wlr_renderer_autocreate no
  longer takes a struct wlr_egl * as parameter.
• Drop EGL from wlr_renderer_autocreate (Drop EGL from wlr_renderer_autocreate #2639): wlr_renderer_autocreate
  no longer takes the arguments EGLenum platform, void *remote_display.
  Instead it takes a struct wlr_backend *.
• render/egl: remove config_attribs, wlr_egl.config and wlr_egl_{create,destroy}_surface (render/egl: remove *config_attribs, wlr_egl->config and wlr_egl_(create, destroy)_surface #2666)
• region: make wlr_region_create private (region: make wlr_region_create private #2662)
• surface: make wlr_surface_create private (surface: make wlr_surface_create private #2814)
• Add static+const qualifiers (Add static+const qualifiers #2720): wlr_tablet.impl is now const
• Update output transform matrix calculation (Update output transform matrix calculation #2770): the projection has been moved from wlr_output.transform_matrix to the GLES2 renderer. Compositors using wlr_output.transform_matrix only with the GLES2 renderer don't need an update.
