 # Latest Windows release
 
-## v0.6.26 — 2026-11-02
+## v0.6.27 — 2026-11-02
 
 ## Changes
-- Settings → Sync… is available to everyone. Connect your own OpenBao KV v2 with a username and password; synchronization is disabled by default and no server is built in.
-- Synchronize at startup, approximately two seconds after saving settings, and every 10 minutes in the background. Local operation continues offline.
-- Merge independent settings changes and resolve conflicts individually, with local/server values shown side by side. Unresolved values stay pending while independent changes synchronize. Every server write uses CAS to protect concurrent changes.
-- Snippets have stable IDs and retained deletion records. Independent snippets, renames and text edits can merge; deletion versus editing and duplicate shortcuts/triggers receive explicit conflict handling.
-- Personal dictionaries, exclusions, shortcuts and layout preferences synchronize. Startup, history, local paths, connection details and credentials stay on the PC. Passwords use Windows Credential Manager; cached sync state uses DPAPI.
-- Existing profiles migrate to sync envelope version 2. Update every participating PC before using the new synchronization behavior.
+- Tray and clipboard context menus support underlined access keys. Press the letter while a menu is open (S for Settings, X for Exit).
+- Alt+letter activates buttons and checkboxes in Settings, Snippets, Logs, synchronization/conflict, OCR and dictionary dialogs. Selected field labels also move focus to their input.
+- Clipboard history supports Alt+letter for its actions and search while retaining Enter, Shift+Enter and Ctrl+digit shortcuts.
+- Press Alt to reveal Windows' hidden underlines. Shortcut capture still records Alt combinations; press Tab to leave the capture field before using form access keys. Captions and access keys currently use English letters.
 
 ## Validation
-91 sync/protocol/conflict checks, 423 native regressions, 510 input/UI checks, screenshot editor and PNG save regressions, shared wheel handling, notification registration, 48 updater checks and updater progress checks. Initial upload and personal-dictionary synchronization were confirmed against the user's OpenBao. Two-physical-PC production testing is still pending.
+91 sync/protocol/conflict checks, 423 native regressions, 513 input/UI checks (including Windows Alt+K dispatch and checkbox toggling), shared wheel handling, screenshot editor and PNG save regressions, notification registration, 48 updater checks and updater progress checks.
 
 ## Limitations
 OpenBao synchronization is experimental and requires a reachable HTTPS server with a trusted certificate, KV v2 and a provisioned userpass account/policy. It does not provide account registration, MFA login, non-root namespaces or reverse-proxy URL prefixes. Ordered layout/language lists are resolved as whole settings. Deletion records are retained without expiry. Missing keyboard layouts block applying a profile. Download/Upload replace a whole profile and are intended for initial setup or deliberate recovery; use Resolve individual conflicts for normal conflicts. Existing browser-selection and clipboard/accessibility limitations remain unchanged.
