Latest Windows release
v0.6.52 — 2026-11-06
Changes
- Add Arc (U) to the screenshot editor toolbar, with its own cursor and drawing hint. Drag a rectangle to draw an open half ellipse; the endpoints are not joined by a straight chord.
- Resize arcs using the corner handles, rotate them with the round handle (Shift snaps to 15 degrees), move or clone them, and adjust their color, thickness and line style. Undo/redo, connector attachment and full-resolution PNG export preserve the open curve.
- Widen the editor's minimum window width to fit the additional toolbar button.
- Retain v0.6.51 Telegram Web K chat profiles in Chrome and application-specific snippets, including their compatibility requirements below.
Validation
Passed 332 native checks, 568 input checks, 674 chat-profile checks, 108 sync checks, dictionary equivalence (140,939 words), wheel, StayHere, Utilities, screenshot UI/save/registration, 54 updater checks and updater progress checks. Arc checks cover toolbar selection, drawing, open-curve hit testing and rendering, resizing, rotation, connector attachment, undo/redo and PNG export. Inspected an actual editor rendering with the Arc tool selected. Published package checksums, manifests, executable versions, update selection and English/Ukrainian Wiki pages are verified during publication.
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 remain local, included in manual export/import and excluded from cloud synchronization.
Download KSwitcher-win-x64.zip with SHA256SUMS.txt. The package contains no personal settings, credentials or clipboard history.
Publish stable release-vX.Y.Z tags matching the executable version. Keep v0.4.2 as the last legacy tag.
