URGENT: Changes detected in Google Vision that affect the analysis of documents.

[Big Data Mining]

Among the legacy, stable and latest models, we detected there Main detected breaking changes: 1. The segmentation of blocks in some cases became less comprehensive, however, the order is very different from the legacy model. 2. Some unordered blocks and the segmentation of some blocks became generic. 3. Change in paragraph segmentation and clutter. 4. Overlapping blocks with a more generic segmentation. 5. Segmentation of blocks that were previously identified together are now separate.

@bigdatamin, we have tracked down the root cause and are working on an option to revert back to the previous reading order. We will also update the release note in the future when there are significant AI quality upgrades. Thanks!

The reading order is one of the big issues. But, what about the others, like blocks/paragraph segmentation, etc?

• The segmentation of blocks in some cases became less comprehensive, however, the order is very different from the legacy model, as you can see in the example below. 
• Some unordered blocks and the segmentation of some blocks became gener.
  
• Blocks 7 to 14 became a big block in the latest versions.
  
• Reading the seal stamps, before they were just one thing, in the latest versions there are several blocks and they are disordered.
  

• Change in paragraph segmentation and clutter.
  

• Overlapping blocks with a more generic segmentation.
  

• Segmentation of blocks that were previously identified together are now separate. As an example of the joint information at the end of the document.
  
• Unordered blocks.

Just another point: the legacy model will not be avaiable after August 20 and this huge big problems are not solved! I cannot believe that Google is oferring a product ready for production with this kind of versioning issues, bad communcation with the community and not supporting background compatibility.
