 # Latest Windows release
 
-## v0.6.48 — 2026-11-05
+## v0.6.50 — 2026-11-06
 
 ## Changes
-- Add manually configured language subsets for Telegram Desktop and Microsoft Teams chats. Open **Settings → Languages → Languages for a chat...**, choose a chat and one or more languages, then **Use languages → Save**.
-- Apply the matching profile to **Alt+Shift**, **Win+Space**, reverse **Win+Shift+Space**, and KSwitcher's **Next layout** conversion. Explicit shortcut bindings take precedence. Without a matching profile, normal Windows behavior and the global KSwitcher cycle remain available. Direct layout shortcuts retain their targets.
-- Match the application and visible chat name; ignore Telegram unread badges. Same-name chats share a profile, renamed chats need a new one, and Teams currently supports `Chat | name | Microsoft Teams` desktop titles. Profiles are local, included in manual export/import and excluded from OpenBao sync. Viber is not included.
-- Organize Settings into **General, Languages, Shortcuts, Clipboard and Tools** tabs. Remove overlapping controls, reduce the window height and preserve drafts across tabs. Save, Cancel, Import and Export remain available on every tab; existing preferences and shortcut defaults are preserved.
-- Rename the tray **Utilities** menu to **Tools**. Keep bundled StayHere and the v0.6.47 multi-word replacement behavior.
+- Disable experimental Viber chat OCR to remove repeated recognition and its language-switching delays. No Viber OCR runs in the background, on layout switching/conversion, or when opening the chat-profile dialog.
+- Keep saved Viber profiles and show them as inactive. Viber uses ordinary Windows layout switching and the global KSwitcher Next layout cycle. No settings reset is needed.
+- Preserve Telegram Desktop and Microsoft Teams chat profiles, their shortcuts and behavior. Clipboard/image OCR and Tesseract options remain available.
 
 ## Validation
-Passed 653 chat-profile/UI checks (including visible-control overlap checks on all five tabs), 332 native checks, 564 input checks, 105 sync checks, complete dictionary equivalence (140,939 words), shared wheel regressions, isolated StayHere lifecycle and Utilities checks, screenshot UI/save/registration checks, 54 updater checks and updater progress UI checks. Development visual checks covered the five tabs at 250% scaling; the release fixture also passed at 100%. Release binary versions, archive contents, manifest hashes and published downloads are verified as part of publication.
+Passed 653 chat-profile/UI checks including saved Viber-profile persistence, 332 native checks, 564 input checks, 105 sync checks, complete dictionary equivalence (140,939 words), wheel, StayHere, Utilities, screenshot UI/save/registration, 54 updater checks and updater progress checks. The disabled Viber OCR module is not compiled into the application. Release versions, manifest, archive and published downloads are checked during publication.
 
 ## 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, close its configurator and screenshot editors, and extract the entire ZIP into its installation folder. Keep personal `data/`, customized dictionaries and your own tools. Keep the three KSwitcher executables together; StayHere runs independently.
 
-When synchronizing phrase replacements across PCs, update each participating PC to v0.6.47 or newer: older versions reject spaces in replacement pairs. Chat language profiles do not synchronize.
+Chat profiles remain local, are included in manual export/import and excluded from cloud synchronization. Saved Viber profiles require v0.6.49 or newer to load, even while inactive; retain a backup before downgrading. Phrase replacement synchronization requires v0.6.47 or newer on participating PCs.
 
 Download **KSwitcher-win-x64.zip** with **SHA256SUMS.txt**. The package contains no personal settings, credentials or clipboard history.
