Changelog

Sourced from hjkl-clipboard's changelog.

[0.5.3] - 2026-05-05

Fixed

• Wayland self-paste no longer deadlocks. When the consumer owns the clipboard data_source and then calls get(Clipboard, …) (e.g. CEF reading the system clipboard during a Ctrl+V into a contentEditable), the bg thread previously issued offer.receive(write_fd) and blocked in read_fd_to_end(read_fd), but the matching data_source.send event for our own source could not be dispatched while the bg thread was stuck in that read. do_get now short-circuits when state.clipboard_source is Some and returns the cached payload directly, bypassing the pipe round-trip entirely. Same for Selection::Primary via state.primary_source. Closes kryptic-sh/buffr#34 (issue #4 follow-up — 0.5.2 only fixed the inverse direction where an external app pasted from us).

[0.5.2] - 2026-05-05

Fixed

• Wayland data_source.send callback no longer performs a blocking write() on the bg thread. The write fd received via SCM_RIGHTS is immediately set to O_NONBLOCK; if the pipe buffer is full (EAGAIN) the write is deferred as a PendingWrite entry and drained on the next poll(2) iteration via POLLOUT. A 5-second deadline closes abandoned fds to prevent leaks. Both the ext_data_control_source_v1.send and zwp_primary_selection_source_v1.send paths are fixed. Previously, a slow paste receiver (e.g. CEF 147 OSR on Wayland, kryptic-sh/buffr#34) could stall the bg thread indefinitely, causing any subsequent set_text() call from the UI thread to block on a Condvar for 7+ seconds until the watchdog killed the process (issue #4).

[0.5.1] - 2026-05-04

Docs

• Internal CHANGELOG hygiene: backfilled missing release entries and added reference link definitions for all version headings. No functional changes.

[0.5.0] - 2026-05-03

Added

• Public Backend trait. Promoted from pub(crate) to pub, with new kind() and capabilities() methods plus async variants (set_async / get_async / clear_async / available_async) defaulted to ClipboardError::UnsupportedAsync. Downstream crates can now implement custom backends, decorators, or mocks.
• BackendKind enum for stable backend identification (Wayland, X11, MacOs, Windows, Osc52, Mock, SshAware).
• Capabilities bitflags (bitflags = "2"): WRITE, READ, CLEAR,
