+### Changed
+- **The release binary is 2.5× smaller** (`curator` 42.7 → 17 MB, `tipy-dne`
+  6 → 1.8 MB): the release profile strips debug symbols, uses LTO with a single
+  codegen unit and optimises for size (`opt-level = "s"`), and the GUI renders
+  through OpenGL (`glow`) instead of `wgpu`.
+
+### Dependencies
+- `eframe` with the `glow` renderer only (default features off; `wgpu` and the
+  web screen-reader feature dropped).
