wallr v0.8.4

highlights

• wallpaper engine no longer reports success while only checking file existence; source validation remains explicit before theme and hooks.
• async wallpaper entry point no longer runs blocking hook and theme work on the async executor thread.
• gpu adapter enumeration is shared between detection and selection.
• wayland unsafe handle wrappers now document their lifetime invariants.
• workspace and references bumped to 0.8.4.

validation

• formatting, workspace build, clippy, and all 72 tests passed locally.
• dependency and security audit could not run due to no network access (lol 😂).
