 ## [Unreleased]
 
+### Added
+- Resolved value annotations: nondeterministic words (`rand`, `choose`, `cycle`, `bounce`, `wchoose`, `coin`, `chance`, `prob`, `exprand`, `logrand`) now display their resolved value inline (e.g., `choose [sine]`, `rand [7]`, `chance [yes]`) during playback in both Preview and Editor modals.
+
+## [0.0.9] - 2026-02-08
+
+### Website
+- Compressed screenshot images: resized to 1600px and converted PNG to WebP (8MB → 538KB).
+- Version number displayed in subtitle, read automatically from `Cargo.toml` at build time.
+
 ### Added
 - Inline sample finder in the editor: press `Ctrl+B` to open a fuzzy-search popup of all sample folder names. Type to filter, `Ctrl+N`/`Ctrl+P` to navigate, `Tab`/`Enter` to insert the folder name at cursor, `Esc` to dismiss. Mutually exclusive with word completion.
 - Sample browser now displays the 0-based file index next to each sample name, making it easy to reference samples by index in Forth scripts (e.g., `"drums" bank 0 n`).
@@ -12,6 +21,9 @@ All notable changes to this project will be documented in this file.
 - Header bar stats block (CPU/voices/Link peers) is now centered like all other header sections.
 - CPU percentage changes color when load is high: accent color at 50%+, error color at 80%+.
 
+### Fixed
+- Soundless emits (e.g., `1 gain .`) no longer stack infinite voices. All emitted commands now receive a default duration of one beat unless the user explicitly sets `dur`. Use `0 dur` for intentionally infinite voices.
+
 ## [0.0.8] - 2026-02-07
