Release notes overview

This section contains release notes for Itential Automation Gateway (IAG) versions 4.3, 2023.3, and 2023.2. Each changelog entry lists the bug fixes, improvements, and security updates included in that version.

IAG versioning practices

All supported versions of IAG are assigned unique identifiers (version numbers) to help manage different versions and releases of the software to ensure customers can access the correct version they need.

Here’s an explanation of how Itential names IAG versions to help you understand the nature of changes between versions:

• Component version — This identifies the build version of the Platform application (i.e., IAG) distributed in a maintenance release. For each change made to the source code as part of a development build, whether it’s a bug fix or improvement, there is a component version bump. Components are versioned independently of product release versions. Also, multiple builds can be created for a single release version.

• Release version — This identifies the Platform release version of IAG made available to customers in a maintenance release. Release versioning helps to track different iterations of the software and increments each month as part of the maintenance release.

Each versioning scheme is purposely designed to provide a structured mechanism of releasing and tracking Itential’s product versions, enabling developers to identify bugs more efficiently and maintain code integrity.

Release types

As of IAG 4.3, Itential uses semantic versioning in the format MAJOR.MINOR.MTCE:

• Major releases introduce breaking changes or significant architectural updates that may require action before upgrading.
• Minor releases introduce new capabilities and enhancements. They increment the minor version number (for example, 4.3.0 → 4.4.0 → 4.5.0).
• Maintenance releases deliver bug fixes and security patches. They increment the patch version number (for example, 4.3.0 → 4.3.1 → 4.3.2).

Tags

Each changelog entry is tagged to help you quickly identify what kind of changes the release contains.
