This page details 1.4.0-only changes: expanded AI engine, stamp & vertical text tuning in margins, multi-PDF workspace improvements, patterns/word-sets controls, PDF viewer stability and release notes in Home. Date: 2026-07-29. It is the last version with the classic frontend; from 1.5.0 minimal only.

AI engine (Anonimatum-IA)

• Addresses: postal codes with hyphen/space; code and locality on separate lines (admin contracts); cadastral references.
• Phones: international prefix +34 and common scanned/OCR formats.
• False positives: reduction in ENS docs, contracts and tenders (legal terms homonymous with surnames, e.g. «contra», «parte»).
• Margin vision: detection of stamps, signatures and QR on sides; Images & logos option (logos, handwritten signatures, faces on raster pages).
• Vertical text: better detection of names and blocks in rotated margin columns.

Backend (AnonimatumBack)

• `PdfServiceImpl`: box calibration for vertical rotated text (lateral stamps); GDPR stop-words with strict whole-word match; better overlay ↔ text-layer alignment.
• Office/batch anonymization: fixes for presentation (PPT/PPTX) processing in background queue.

Interface (App-Anonimatum-Minimal)

• Release notes in Home (`/anonimo/home`): accordion with history 1.4.0, 1.3.0, 1.2.0, 1.1.0; «Current» badge on latest.
• Version in header (e.g. `v1.4.0`) from env config.
• Patterns: select / deselect all catalog patterns at once.
• Word sets: integrated search in anonymization screen.
• Multi-PDF workspace: smoother handling of multiple docs with independent config.
• PDF viewer: misalignment & zoom fixes; more stable overlay with rotated text.
