ScanLens Changelog

This page tracks significant changes to ScanLens since launch. It is written for users, not developers — we mention the things that actually affect how the app works rather than every internal refactor. For the engineering-level changelog with ADR references, see the repository. Dates are release-to-App-Store dates, not development dates.

Version 1.5.4 — March 15, 2026

Launch audit and scanner refinements. This release is a broad quality pass on memory use, background behavior, and the core scanning flow. Plus a better Book Mode.

Scanner flow redesign

The scan button now goes straight to the camera instead of showing a mode picker first, cutting one screen and one tap from every scan. Mode selection moved to a swipeable picker inside the camera itself. The document detail toolbar was simplified from 10 actions to 4 main actions plus a More menu — Share, OCR, Sign, and Edit are what people actually use.

Book mode quality

Dewarping for curved book pages got meaningfully better at recognizing page boundaries, especially for thicker books where the spine shadow confused older versions. Page splitting (two-page spread → two separate pages) is more reliable.

Memory and background behavior

The app now releases GPU memory (roughly 100–120 MB) when backgrounded and recreates it lazily on foreground. This brings resident memory in the background from about 250 MB down to roughly 100–130 MB, which matters on older iPhones where iOS sometimes terminates background apps aggressively.

Other fixes

Dark mode fix for page placeholders (now matches the card color instead of pure white)
Light edit mode (Rotate / Filters / Adjust) now persists through the full-screen transition
Edit button no longer locks if page extraction fails mid-flow
Several memory leaks in the adjust view fixed
Dead code removed (896 lines) — no user-facing change but smaller app binary

Version 1.5.3 — February 19, 2026

Book mode quality and capture speed. A focused release on the scanning performance for thick documents and books.

Faster capture on iPhone 15 and newer (improved camera pipeline)
Book mode dewarping accuracy improvements
Reduced capture latency in batch mode

Version 1.5.1 — January 28, 2026

Polish and fixes. A quick follow-up to 1.5.0 addressing reported issues and rough edges.

Fixed a crash when scanning while the device was in low-power mode
Improved OCR accuracy for Cyrillic scripts
Cloud sync retry behavior is more forgiving on flaky connections
Signature placement now snaps to form fields where possible
Small UI polish throughout (spacing, contrast, haptics)

Version 1.5.0 — January 25, 2026

AI features. This release brought a set of new intelligent capabilities to the app.

Improved on-device OCR using the latest Vision framework
Smarter edge detection for unusual document shapes
Auto-classification of scan type (receipt, ID, document) for default settings
Better handling of shadows and glare on glossy paper

Version 1.4.1 — January 25, 2026

UI polish and gesture controls. Smaller release focused on the interaction layer.

Added swipe gestures for page navigation in document view
Pinch to zoom improvements
Keyboard shortcuts on iPad (Cmd+N for new scan, Cmd+F for files)
VoiceOver improvements on the mode picker and page indicator

How we version

ScanLens follows a standard major.minor.patch version scheme.

Major version (1.x, 2.x) — significant changes to the app's architecture or capabilities
Minor version (1.5.x, 1.6.x) — new features that are backward-compatible
Patch version (1.5.3, 1.5.4) — bug fixes, performance improvements, minor polish

We do not enforce a rigid release cadence. Some months have two releases, some have none, depending on what is ready to ship and what needs more testing.
