 ## [Unreleased]
 
+## [0.3.0] - 2026-07-05
+
+### Added
+- `--tee` flag to mirror input through stdout while copying, so termcopy can
+  sit inside a pipeline like tee(1) with the clipboard as a second destination
+- `--output <stdout|tty>` flag to pin the escape-sequence destination explicitly
+- Output cascade: the escape sequence goes to stdout when it is a terminal,
+  otherwise to the controlling tty, otherwise falls back to stdout so remote
+  copies over ssh without a tty still reach the local terminal
+
+### Fixed
+- Nix docker image no longer pulls the Rust toolchain into its closure,
+  shrinking it from over 2GB to 17MB
+
+### Changed
+- Simplified code, tests, and build tooling; hardened the release pipeline
+  and nix builds
