Latest Windows release
v0.6.54 — 2026-11-06
Changes
- Add Smoothing (0–100%) to the screenshot editor toolbar. Adjust the selected pencil stroke, or set the default for new strokes when no pencil stroke is selected (initially 25%). Apply to all strokes updates all pencil strokes in the image and the default. Text, highlights and geometric shapes are unchanged.
- Retain original pencil samples: zero restores the original path, and reducing smoothing restores detail without accumulating distortion. Moving, endpoint editing, cloning, undo/redo and PNG export preserve the chosen geometry. Each slider drag or bulk change is one undo step. Very short strokes remain unchanged; Shift-constrained and linked strokes start unsmoothed but can be adjusted explicitly. Shape recognition remains separate.
- Show No unsaved changes in Settings with Save disabled until edits are pending. Show Unsaved changes — click Save to apply for pending edits, including accepted chat-language, OCR and automatic-correction preferences. Cancelling a child dialog or restoring the original values updates the state immediately. Separately saved snippets do not falsely mark Settings as unsaved.
- Avoid creating empty personal-dictionary entries when accepting unchanged automatic-correction options, preventing a false unsaved-state indication.
- Retain chat-language synchronization from v0.6.53 and Arc (U) from v0.6.52.

Upgrade and compatibility
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.
Update every synchronizing PC to v0.6.51 or newer before sharing application-specific snippets. Older versions do not understand application restrictions and may treat scoped snippets as global. Keep a backup before downgrading. Settings with Telegram Web profiles require v0.6.51 or newer. Chat profiles now synchronize from v0.6.53. Update every synchronizing PC to v0.6.53 or newer before syncing: older clients reject the chat-profile field. Synchronization stores application names, visible chat names and language IDs on your configured OpenBao server. No message contents are included.
Download KSwitcher-win-x64.zip with SHA256SUMS.txt. The package contains no personal settings, credentials or clipboard history.
