 # Latest Windows release
 
-## v0.6.31 — 2026-11-03
+## v0.6.32 — 2026-11-03
 
 ## Changes
-- Fix conversion failures when an editor such as Viber omits trailing ASCII spaces from Ctrl+C. KSwitcher recovers those spaces only when Windows accessibility confirms the full selection in the target application's focused, non-password control. Exact recent-text and previous-result checks still apply.
-- Recheck the same control and full selection before pasting a recovered range. Read back the replacement even when Write log is disabled; an unknown or mismatching result does not seed repeat conversion or switch the layout.
-- The shared copy path supports manual conversion, automatic dictionary correction, repeat conversion and Undo. No shortcut, setting or default has changed.
+- Fix the screenshot panning regression test for high-DPI displays. It now derives the image zoom from the actual viewport dimensions, centers the image, and checks that both axes have enough clearance for the tested drag.
+- At 240 DPI (250% scaling), the previous fixture's 1600 × 1200 image still fit inside the 2468 × 1389 viewport. The editor correctly prevented panning, but the test incorrectly expected a 15 × 10 pixel movement.
+- Application behavior, shortcuts, defaults and settings are unchanged. The verified Viber trailing-space recovery from v0.6.31 remains included. No screenshot-editor workaround is needed for this test failure.
 
 ## Validation
-Live Viber validation converted `Ghbdsn ` to `Привіт ` and confirmed the retained trailing space without sending a message. Final isolated conversion and typo integration runs passed, including real clipboard-space stripping, two spaces within surrounding text, repeat conversion, Undo, missing/unrelated selection rejection, and blocked-paste state clearing with logging disabled. 483 native, 541 input/UI, 105 sync and 48 updater checks passed, as did wheel batching, screenshot PNG saving, screenshot registration and updater progress checks. Earlier integration attempts encountered clipboard contention/restoration and log-rotation assertions; the isolated final rerun passed. The unchanged screenshot UI suite still fails at `middle drag pans enlarged canvas`; screenshot implementation and test source are unchanged from v0.6.30. All three packaged executable versions and all 12 manifest file sizes/hashes were verified; no personal data is packaged.
+The full `build.ps1 -Stage -Test` run passed: 105 sync checks, shared wheel batching, 483 native regressions, 541 input/UI checks at 240 DPI, the full screenshot editor UI suite (including the corrected pan test), PNG saving, screenshot registration, 48 updater regressions and updater progress UI checks. All three packaged executable versions and all 12 manifest file sizes/SHA-256 hashes were verified; the package contains no personal data.
 
-## Limitations
-Recovery requires a non-empty clipboard prefix and a single readable accessibility selection whose only additional characters are trailing ordinary spaces. Tabs, line breaks, missing letters, ambiguous or inaccessible selections are not reconstructed. Accessibility and editor timing can still prevent a conversion. This is not a general fix for all asynchronous editor failures.

-**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.
+## 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 screenshot editors and extract the entire ZIP into its installation folder. Keep personal `data/` and customized dictionaries.
 
 Download **KSwitcher-win-x64.zip** with **SHA256SUMS.txt**. Keep all three executables together. The package contains no personal settings, credentials or clipboard history.
