Version decoder

From The x3270 Wiki

Version numbers for the x3270 family take the following format:

major . minor type iteration

For example, 4.0ga13.

The definitions of the fields are as follows:

major
The major number of the release. Between major numbers, there is no guarantee of backwards compatibility. For example, x3270 4.0 (major version 4) may be incompatible with x3270 3.6 (major version 3).
minor
The minor number of the release. Releases are generally backwards-compatible. For example, x3270 4.1 is backwards-compatible with x3270 4.0.
type
The type of the release. One of the following values:
Type Description
alpha Alpha test. The code may include functionality that is not in its final form. It is generally functional, but not as well-tested as Beta code.
beta Beta test. The code is in its final functional form, but has received limited testing and bugs may be present.
ga General availability (GA). The code is in its final functional form and has been tested extensively.
pre Pre-release code. This is code built without a release tag for specific testing or demonstration purposes, and there no specific guarantees of stability.
iteration
A sequential iteration number within a minor release. For example, 4.0ga13 has additional bug fixes and small enhancements compared to 4.0ga12.

Iteration numbers are sequential across the different types. For example, there may be releases numbered 2.1alpha1 through 2.1alpha5, then Beta releases numbered 2.1beta6 through 2.1beta7, then finally GA releases numbered 2.1ga8 through 2.1ga10.

Pre-release code version numbers generally indicate the iteration that the features may be incorporated into in the future, for example, 2.1pre6 indicates a feature set that may be part of 2.1beta6 or 2.1ga6.
