XPlane2Blender Versions

XPlane2Blender follows a fairly standard software development cycle and uses version numbers to keep track of it's progress and as metadata in .blend and .obj files to help debug problems. A fully history of every version number that a .blend file has been opened with is also kept (with restrictions).

What Version Do I Choose?

Use the latest full release candidate from github for the safest and most stable experience possible. Download the .zip file that starts with "io_xplane2blender" (not Source code.zip!) and read the installation instructions.

What Version Do I Have?

The most complete place to check what version you have is at the top of the scene settings. It should look like this:

Broken down, its part's represent:

"3.4.0" - Major, minor, and revision number (part of any Blender Addon)
"rc" - The build type (see below)
"1" - What number release candidate this is

After the "+":

"4" - The data model version
"20180102175505" - When this build of the plugin was created (in the UTC timezone)

Using a build, even the latest release candidate, without a build number is dangerous! It means any number of untracked changes could be infecting your .blend file with no dialog or record of changes! Using a build without a build number will receive a large warning and no green checkmark for release candidates.

Build Types

New features and fixes are added over the course of a development cycle. A cycle is broken into segments explained in this table (organized from safest to least safe).

Build Type


State Of Addon



Release Candidate

Contains all tested work from the beta: the most tested, stable, and documented. Rarely are new changes introduced here

As is code's nature; bugs could still exist

"Full Release" and "RC" are synonyms. There can be multiple RCs because our work is never done!


New features and fixes are being polished, tested, and integrated together

Bugs, new and old, can corrupt data

Make backups! You may have to redo or discard work. Follow development closely and communicate with us! Your voluntary participation is a huge help to XPlane2Blender!


Code is at its most malleable and unstable

Everything and anything could happen!

Only developers and users they're directly communicating with should use a dev build!

What Versions Has This .blend File Been Opened With?

By enabling the Plugin Development section in the bottom of the scene settings, you can see a history of every version of XPlane2Blender this .blend file has been used with (things get less accurate if you open a .blend file in pre-3.4.0-beta.5 versions). This is a read only list, shown in chronological order, developed to debug automatic updater problems. It is only updated when there is a difference (excluding the build number) between last and current version numbers.

What About Checking Out Code Directly From git?

This is ABSOLUTELY NOT RECOMMENDED! You will never have build numbers (unless you make a build yourself) and severely increase the chance of corrupting your work. If you feel the need to checkout code from git, talk to us first and we'll work it out your needs together!
