 ## [Unreleased]
 
+## [1.6.3] - 2026-10-20
+
+### Fixed
+- `SIGSEGV` while resizing the window. The GTK embedder's OpenGL compositor uploaded the frame using
+  the window's new dimensions while its pixel buffer still held the previous size, so `memcpy` read
+  past the end of the buffer (`engine/.../linux/fl_compositor_opengl.cc`). Fixed upstream in
+  flutter#187626, which is not part of Flutter 3.44.7 — the Linux build now uses Flutter 3.47.7,
+  where the compositor derives the texture size from the framebuffer itself.
+
 ## [1.6.2] - 2026-10-14
