 # Latest Windows release
 
-## v0.6.10 — 2026-10-29
+## v0.6.15 — 2026-10-30
 
 ## Changes
-- Preserve typing during automatic layout correction: queue key presses and releases until replacement, clipboard restoration and layout switching finish. Preserve modifiers and Backspace; collapse temporary selection before replay when a correction is rejected.
+- Preserve typing that arrives while a snippet is being expanded.
-- Add My dictionary fields for English, Ukrainian and Russian in Auto-correction options. Enter correct words separated by commas or new lines; save them with settings without editing dictionary files, sorting entries or assigning ranks.
+- Add `{enter}` to press Enter after insertion and cursor placement, with an Insert Enter marker button. Use `{{enter}}` for literal text.
-- Accept unsorted dictionary files and duplicate entries, retaining the lowest rank for duplicates. Include Ukrainian `реліз` in the bundled vocabulary so `релыз` can be corrected when Russian and Ukrainian are enabled.
+- Suppress automatic correction during snippet expansion and buffered typing, without changing the global setting. Normal typing resumes automatic correction afterward.
+- Restore the caret when snippet verification fails and record snippet failures in diagnostic logs.
+
+Includes the earlier automatic-correction and log-viewer improvements. Existing modern releases update directly to this version without installing intermediate releases.
 
 ## Validation
-Native regression checks cover personal words, settings persistence, language validation, dictionary ordering and duplicate ranks. Input/UI checks cover personal-word entry and normalization. Native editor integration covers typing with Shift and Backspace during successful and rejected corrections. Release checks also cover screenshot UI, isolated notification registration and updater validation.
+223 native regression checks, 472 input/UI checks, screenshot editor and notification registration checks, 45 updater checks and updater progress checks. Targeted native integration checks cover continuous snippet typing, clipboard restoration, actual Enter key events, punctuation preservation, suppression of automatic correction and its resumption afterward. The updated development build was also confirmed by the user in Notepad. The broader integration suite showed intermittent failures during earlier interactive runs; it is not claimed as fully passing.
 
 **Upgrade:** choose Update in the tray menu. Legacy v0.3.0–v0.4.1 clients first receive the v0.4.2 compatibility bridge, then the current full release. v0.2.3 and earlier require manual installation.
-For manual installation, exit KSwitcher and extract the entire ZIP into its installation folder. Keep personal `data/` and customized dictionaries. Existing customized dictionary files may be preserved by the updater; use My dictionary to add missing words without replacing those files.
+For manual installation, exit KSwitcher and extract the entire ZIP into its installation folder. Keep personal `data/` and customized dictionaries.
 
 Download **KSwitcher-win-x64.zip** with **SHA256SUMS.txt**. The package contains all three executables, a release manifest, offline dictionaries, documentation and license notices. It contains no personal settings, clipboard history, Tesseract installation or language models.
