PaddleOCR Release SOP

中文

Scope

This document describes the standard release process for PaddleOCR.

Release Types

The current process supports the following two release types:

• bump patch: for example, 3.4.0 -> 3.4.1
• bump minor: for example, 3.4.x -> 3.5.0

For bump major:

• The current process does not directly support this scenario
• A major release process should be discussed and designed separately, for example by introducing an additional branch or a new preparation flow

Release Principles

• Daily development happens on main
• Official releases are made only from release/X.Y
• Official tags must use vX.Y.Z
• Do not create official release tags on main

Standard Release Process

1. Confirm the release target

First confirm which release line this release belongs to and what the target version is.

Examples:

• Release 3.4.1 on release/3.4
• Release 3.5.0 on release/3.5

2. Create or switch to the release branch

If the release line does not exist yet, create the corresponding release/X.Y branch from main.
If it already exists, switch to that branch and continue release preparation there.

Requirements:

• One minor release line corresponds to one fixed release/X.Y branch
• That branch should contain only the release content and patch fixes for that line

3. Pick release content from main

Based on the release scope, cherry-pick the required commits from main into release/X.Y until the release content is ready.

Requirements:

• Only pick what is needed for the current release
• Avoid bringing unrelated new features into the release branch
• If there are release-specific fixes on the release branch, keep them limited to the current release scope

4. Complete pre-release checks

Complete pre-release checks on release/X.Y.

At minimum, this should include:

• The current branch is correct
• The working tree is clean
• The version is as expected
• Key functionality is verified
• Required tests, builds, packaging, and regression checks have passed
• Release notes are ready

5. Create the official tag

Once the release is ready, create the official tag on release/X.Y:

• The tag format must be vX.Y.Z

Examples:

• v3.4.1
• v3.5.0

Requirements:

• The tag must be created on the release branch for the current official release
• Do not use development tags as official release tags

6. Publish the GitHub Release

Create a GitHub Release based on the official tag for this release.

7. Update dependency constraints and release notes

If this release is the first release of a new minor line, or if it changes PaddleX dependency requirements, update the related release materials before or after the official tag is published.

At minimum, this should include:

• Checking whether the paddlex dependency constraints in pyproject.toml match the target release
• Checking whether installation docs, upgrade notes, and release notes are aligned with the release version

Completion criteria:

• The paddlex dependency constraints match the target release
• The version information in the documentation matches the released version

8. Sync the release branch lineage back to main

After the first official release of a new release/X.Y line is completed, sync the lineage of that release/X.Y branch back to main.

This is a fixed step in the current workflow and should be done at least once for each new minor release line.

Purpose:

• Ensure main correctly reflects that the release line has produced an official version
• Keep subsequent development and release cadence aligned

Requirements:

• Perform this once after the first official release of each new release/X.Y
• For later patch releases on the same release/X.Y, it is usually not necessary to repeat it

9. Move on to the next development cycle or patch release

After the release:

• main continues with ongoing development
• release/X.Y continues to maintain that release line

If more patch releases are needed later on the same line:

• Continue preparing patches on release/X.Y
• cherry-pick from main as needed
• Repeat the relevant steps in this SOP

How to Handle Different Bump Types

Patch Release

Applicable scenarios:

• Fixing production issues
• Small compatibility fixes
• Documentation, dependency, or stability patches

How to handle it:

• Continue preparing changes on the existing release/X.Y
• Create the next patch tag, for example v3.4.2

Minor Release

Applicable scenarios:

• Starting a new release line
• Releasing the next stable version, for example 3.5.0

How to handle it:

• Create a new release/X.Y from main
• Prepare the release following the standard process
• Create the first official tag, for example v3.5.0
• Update paddlex dependency constraints if needed
• Sync the lineage of that release branch back to main after the release

Major Release

Current conclusion:

• It is not included in this SOP for now
• A separate process needs to be discussed and designed later

Before a dedicated solution is defined, do not directly reuse the current minor/patch process for a major release.

Release Checklist

Before each release, confirm the following:

• The target version and corresponding release branch have been confirmed
• The content on the release branch is ready
• The release scope has been finalized
• Key tests and regression checks have passed
• Release notes are ready
• The official tag uses the vX.Y.Z format
• The GitHub Release has been created
• If this is the first official release on release/X.Y, its lineage has been synced back to main

Daily Maintenance Recommendations

• New features should go to main first
• Official releases should always be performed through release/X.Y
• Patch releases should always be maintained on the corresponding release/X.Y
• For each new release/X.Y, sync its lineage once after the first official release

If the current process changes, this document should be updated accordingly.
