Reference for unit 'LazVersion'

Contains constants which identify the version numbers for the Lazarus IDE installed on the local system.

Overview

Values in the unit are used as the basis for corresponding LCL version numbers in the lclversion.pas unit.

Please note that version numbers used for Lazarus, and the LCL and LazUtils libraries were changed starting with version 3.0. They continue to use a four-part version numbering scheme, like 3.0.0.1, where the component values are:

• Major version number
• Minor version number
• Release number
• Patch level

Starting in version 3.0, the release part of the full version number is no longer maintained. While still included in the full version value, the release number will always be 0 (zero) starting with version 3.0. Major and minor version numbers are used to identify a release or a fixes branch.

An even minor version number, like 3.0 or 3.2, represents a general availability release. An odd minor version number no longer indicates that it is a development (or trunk) version. Instead, an odd minor version number like 3.1 or 3.3 represents a fixes branch. For example: 3.1 would contain bug fixes for the 3.0 release and would be used as the basis for the 3.2 release. Development (or trunk) versions are always represented as minor version number 99; i.e. 3.99 is the development branch for the future 4.0 release. Also, selected commits from this branch are cherry picked to the 3.X family.

Patch numbers identify a release candidate or a general availability release. For example: 3.0.0 RC1 has the full version value of 3.0.0.1. RC2 has the value 3.0.0.2, and the released product could be 3.0.0.3.

lazversion.pas is part of the lazutils package.
