+      "Dictation now keeps a space between segments spoken with a pause in between, so words no longer run together after a silence (PR #464)",
+      "Keyboard shortcuts now work on keyboards hotplugged after Vocalinux starts, with the evdev backend rescanning for new devices and recovering from disconnects (PR #467)",
+      "Vocalinux now detects KDE Plasma Wayland sessions and points you to enable IBus Wayland for reliable text injection, surfaced during install and when wtype injection fails (PR #466)",
+      "Wayland: fixed garbled text on non-US keyboard layouts (AZERTY/QWERTZ/Dvorak) and a clipboard-copy hang; ydotool now pastes through the clipboard, which is layout-independent (PR #480)",
+      "Wayland: use wtype/ydotool instead of IBus on compositors that don't bridge it to native apps like COSMIC, Sway, and Hyprland, fixing silent text drops (PR #486)",
+      "Wayland/IBus: require a real IM engine before using IBus, so a bare xkb layout no longer causes silent text drops on GNOME/Mutter and other compositors (#478)",
+      "Wayland: keep the keyboard layout intact by not running setxkbmap, which was flipping XWayland apps to us after dictation (#474)",
+      "Faster ydotool text injection via an explicit --key-delay (PR #488)",
+      "Settings dialog height capped on high-resolution displays (PR #465)",
