Version - Support policy

This document describes the PDF Services SDK's and Public API's versioning and support policies.

SDK

Versioning scheme

The SDK has a version format of #.#.# (e.g. 1.1.0) where the numbers correspond to a major release, minor release, and patch/update (Major.Minor.Patch). Releases are defined as follows:

Major Releases (1.x.x): Major releases introduce backward-incompatible changes to the APIs and interfaces and start the EOL clock for all previous releases. Developers should plan on migrating their code prior to the end of life of the previous major release.
Minor Releases (x.1.x): Minor releases typically appear quarterly. Changes are backward compatible to the last major release. Minor releases introduce new interfaces. Existing interfaces continue to function but some interfaces may be deprecated; deprecated interfaces will be removed in a next major release.
Patch Releases (x.x.1): Patch releases only deliver critical security or bug fixes as needed. Patch release changes are rolled into the next minor release so that developers can update and deploy new code based on their business requirements.

Public API

Versioning

As mentioned on Public API Docs, each operation has a unique assetId which is passed in Form Parameters. Generally, APIs will be enhanced while keeping them backward compatible. If its functionality can't be enhanced without breaking changes, then its new version will be released with its own unique assetId. The supported older API versions info will be present on Public API Docs

Additionally, the output for the PDF Extract API is generated by a machine learning pipeline that is frequently trained to improve inference of document layout and structure.As a result, while changes to the output structure are not expected between versions, specific results may vary as the model output improves.

Supported versions

This document as well as the URLs on Adobe's website and other documentation link to the latest product version.

Note: Links to repository assets (e.g. GIT, Maven, etc.) direct to the top level directory. To download assets that match the documentation, navigate to the correct version. For example, When using the 1.0.0 Java documentation, you can find the 1.0.0 samples in the GIT repo as follows:

Go to the GIT repo.
Select Releases.
Select and download the needed release.
