### Notification registration and Viber — v0.6.36
Notification registration runs in KSwitcher.Screenshot.exe; keep all three executables together. Startup registration is asynchronous. Viber pastes allow 75 ms for clipboard notifications before Ctrl+V, retaining focus, ownership and selection checks. This mitigates an intermittent clipboard timing issue; it does not guarantee all Viber failures are resolved. UI Automation is unchanged.
### Image history, OCR and duplicate fingerprints — v0.6.37
Image clipboard capture and automatic/uncached manual history OCR run in short-lived KSwitcher.Screenshot.exe processes. Keep all three executables together. Original clipboard formats, image limits, privacy exclusions, Windows OCR, optional Tesseract and searchable encrypted OCR results are preserved. Background OCR is cancelled on shutdown or an OCR-profile change; late results do not recreate deleted entries.
Consecutive duplicates use SHA-256 fingerprints inside the encrypted history index, including pixel fingerprints for equivalent image encodings. Older entries acquire fingerprints on first comparison without a bulk migration. Pins and OCR caches survive duplicate detection; non-consecutive copies still create separate entries. New text no longer loads the preceding image to rule out a duplicate. No shortcut, setting or default changed.
Moving OCR isolates its temporary memory rather than reducing the combined processing peak. A controlled three-run comparison retained about 0.8 MiB less private RAM in the caller after recognition; combined peak RAM was about 55.6 MiB before and 56.6 MiB with the helper. Results depend on the image, OCR engine and system.
