Changes
- Clipboard history runs in a separate, short-lived instance of KSwitcher.exe. Closing history with Esc releases its UI process instead of retaining Windows UI allocations in the resident. Esc also works when the window itself or an action button has focus.
- Search, selected/top entry, pinning, deletion, formatted/plain paste and OCR remain available. Search and selection are saved in encrypted view state. An open full-text viewer keeps the history process alive until that viewer closes.
- Large image clipboard backups and image thumbnail decoding run in KSwitcher.Screenshot.exe. Encrypted temporary files and clipboard-sequence checks preserve the clipboard without keeping full backup images in the resident. Selection reads avoid unnecessary image copies.
- History paste waits briefly for the target application's foreground activation after the history process closes, while retaining input and clipboard ownership checks. Settings and default shortcuts are unchanged; UI Automation remains in the resident.
Validation and memory
The complete staged build passed dictionary equivalence (140,939 words), 105 sync checks, 315 native checks, 561 input checks, screenshot UI/save/registration, 48 updater checks and progress UI, clipboard snapshot/image capture integration, conversion/snippet integration and Windows OCR. Dedicated 500-entry history tests cover repeated Esc, search persistence, pin/delete, full-viewer lifetime, text/image paste, clipboard restoration, rejected foreign requests and helper shutdown. Actual selected/repeated Viber conversion and live Esc were also checked during development.
A local live development-build comparison measured 4.37 MiB before opening history and 4.35 MiB after two open/Esc cycles, versus an earlier roughly 8–9 MiB plateau after closing history. A same-image backup benchmark reduced retained private resident memory from 12.78 MiB to 0.05 MiB. These are workload-specific observations, not a guaranteed footprint. Count all helper processes while history/OCR is active: combined active memory can be higher. No forced working-set trimming was used.
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; history uses another instance of KSwitcher.exe, so no fourth executable is required. 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.
