 # Latest Windows release
 
+## v0.6.77 — 2026-11-13
+
+The screenshot editor remembers the local pencil smoothing default across
+restarts. Adjust the slider with no pencil stroke selected, or use **Apply to
+all**, to save the value for new strokes. Adjusting a selected stroke changes
+only that stroke.
+
+**Українською.** Редактор скріншотів зберігає типове згладжування олівця на
+цьому ПК та відновлює його після перезапуску. Змініть повзунок без виділеного
+штриха олівця або натисніть **Apply to all**, щоб запам’ятати значення для
+нових штрихів. Зміна виділеного штриха впливає лише на нього.
