 # Latest Windows release
 
-## v0.6.31 — 2026-11-03
+## v0.6.34 — 2026-11-04
 
 ## 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.
+- Screenshot editing now uses the four-direction move cursor for both endpoints of lines/arrows, bounding-box shape handles and number-radius handles. The cursor no longer suggests that a horizontal or vertical line endpoint is restricted to one axis.
-- 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.
+- Object bodies, arrow labels and triangle vertices continue to use the same four-direction cursor. Thickness handles retain directional resize cursors perpendicular to the line; rotation handles retain the hand cursor.
-- The shared copy path supports manual conversion, automatic dictionary correction, repeat conversion and Undo. No shortcut, setting or default has changed.
+- This changes cursor feedback only. Dragging, snapping, circle proportions, undo/redo, shortcuts, defaults and dialog access-key behavior are unchanged. The v0.6.33 unsaved-settings warning and visible menu access letters remain included.
 
 ## 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, 551 input/UI checks at 96 DPI, screenshot editor UI checks (including free-movement cursor feedback across drawing tools and horizontal/vertical thickness cursors), PNG saving, isolated screenshot registration, 48 updater regressions and updater progress UI checks. All three executable versions and all 12 package manifest file sizes/SHA-256 hashes were verified; the package contains no personal data.
 
-## Limitations
+## Upgrade
-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.
+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.
