 ## [Unreleased]
 
+## [1.4.0] - 2026-05-16
+
+### Added
+
+- **Inline WYSIWYG edit mode**: clicking a slice now opens a slim inline editor (no more chunky textarea). Bold / italic / strikethrough / inline code / link are toggled directly via shortcuts or a floating toolbar.
+- **Notion-style block flow**: `Enter` splits the current slice into two paragraphs (the new one gets focus); `Shift+Enter` inserts a soft line break inside the slice.
+- **Cross-slice arrow navigation**: `ArrowUp` at the top of a slice moves to the previous slice; `ArrowDown` at the bottom moves to the next.
+- **Raw-markdown escape hatch**: `Cmd+/` or the handle menu's "Edit as markdown" item toggles a slice to a slim raw-markdown editor. Slices containing unsupported inline content (e.g. inline `<img>`, `<sup>`) automatically open in raw mode.
+- **Floating format toolbar**: `Cmd+Shift+F` reveals a small toolbar above the active slice with buttons for the five inline marks.
+
+### Changed
+
+- Edit-mode layout now matches view-mode exactly — no horizontal shift, identical vertical rhythm between blocks.
+- Slice handle is positioned per block type so it aligns with the first line of text instead of the slice's top edge.
