# Changelog
|
||||
|
||||
## 2026-01-17 - 1.7.0 - feat(tests)
|
||||
use Qwen2.5 (Ollama) for invoice extraction tests and add helpers for model management; normalize dates and coerce numeric fields
|
||||
|
||||
- Added ensureOllamaModel and ensureQwen25 test helpers to pull/check Ollama models via localhost:11434
|
||||
- Updated invoices test to use qwen2.5:7b instead of MiniCPM and removed image payload from the text-only extraction step
|
||||
- Increased Markdown truncate limit from 8000 to 12000 and reduced model num_predict from 2048 to 512
|
||||
- Rewrote extraction prompt to require strict JSON output and added post-processing to parse/convert numeric fields
|
||||
- Added normalizeDate and improved compareInvoice to normalize dates and handle numeric formatting/tolerance
|
||||
- Updated test setup to ensure Qwen2.5 is available and adjusted logging/messages to reflect the Qwen2.5-based workflow
|
||||
|
||||
## 2026-01-17 - 1.6.0 - feat(paddleocr-vl)
|
||||
add PaddleOCR-VL full pipeline Docker image and API server, plus integration tests and docker helpers
|
||||
|
||||
- Add Dockerfile_paddleocr_vl_full and entrypoint script to build a GPU-enabled image with PP-DocLayoutV2 + PaddleOCR-VL and a FastAPI server
|
||||
- Introduce image_support_files/paddleocr_vl_full_server.py implementing the full pipeline API (/parse, OpenAI-compatible /v1/chat/completions) and a /formats endpoint
|
||||
- Improve image handling: decode_image supports data URLs, HTTP(S), raw base64 and file paths; add optimize_image_resolution to auto-scale images into the recommended 1080-2048px range
|
||||
- Add test helpers (test/helpers/docker.ts) to build/start/health-check Docker images and new ensurePaddleOcrVlFull workflow
|
||||
- Add comprehensive integration tests for bank statements and invoices (MiniCPM and PaddleOCR-VL variants) and update tests to ensure required containers are running before tests
|
||||
- Switch MiniCPM model references to 'minicpm-v:latest' and increase health/timeout expectations for the full pipeline
|
||||
|
||||
## 2026-01-17 - 1.5.0 - feat(paddleocr-vl)
|
||||
add PaddleOCR-VL GPU Dockerfile, pin vllm, update CPU image deps, and improve entrypoint and tests

* 2. PaddleOCR-VL for recognition (tables with proper structure)

* The structured Markdown has properly formatted tables,
