# Changelog for the Data Extraction API

## 2026.10.1 — 1 Oct 2026

- Improves table extraction for dropped or split tables, wrapped rows, stacked records, shaded regions, merged cells, and false table detection.

- Improves scanned-document accuracy by running optical character recognition (OCR) alongside vision model analysis and resolving disagreements with evidence fusion. (L#NAVI-124, L#NAVI-125, L#NAVI-130)

- Improves OCR language handling so Latin scans are less likely to be misclassified as Cyrillic, Arabic, or Greek, and more configured OCR languages are honored. (L#NAVI-148, L#NAPY-24)

- Charts now return their data as tables by default, and QR codes and barcodes now return their decoded content.

## 2026.9.21 — 21 Sep 2026

- Increases extract schema limits: schema size from 32 KB to 128 KB, total fields from 500 to 2,000, properties per object from 50 to 200, required entries from 50 to 200, and description length from 1,024 to 4,096 characters. (#58687)

## 2026.9.3 — 3 Sep 2026

- Clarifies the classify API documentation and specification: Scores are independent, and non-zero text/image weights are ignored by the engine. (#58039)

## 2026.8.21 — 21 Aug 2026

- Updates parse to return an actionable 400 error for password-protected documents instead of a generic 500. (#57421)

## 2026.8.7 — 7 Aug 2026

- Fixes classify reporting placeholder `pagesProcessed` values, and fixes billing per request instead of per processed page. (#56853)

## 2026.6.5 — 5 Jun 2026

- Updates extract billing so requests are billed as parse and extract components. Responses now include a `price_composition` breakdown. (#53930)

## 2026.5.25 — 25 May 2026

- Adds date-based Data Extraction API versioning via the `x-nutrient-api-version` header. The initial API version is `2026-05-25`. (#53345)

## 2026.4.28 — 28 Apr 2026

- Adds the OpenAPI schema for the Data Extraction API. (#52250)

## 2026.4.2 — 2 Apr 2026

- Introduces the initial Data Extraction pipeline with extraction support for PDFs, images, and Office documents. (#51564)
