Tightrope versions all of it's software releases using the same scheme. Each version number consists of three parts, followed by a build number. Let's use Carousel 6.4.5 for the purposes of illustration.
The version number "6.4.5" is broken up as follows:
- 6 - Major Version
- 4 - Minor Version
- 5 - Maintenance Version
A change in the Major version indicates substantial changes in the way that the software works or looks. For example, Carousel 5.0.0 added the ability to break the display into "Zones".
A change in the Minor version number indicates significant changes in the functionality of the software. As an example, Carousel 6.4.0 added Facebook and Twitter integration along with other features.
A change in the Maintenance version indicates fixes for software malfunctions or, as we refer to them, "bugs" . Carousel 6.4.5 fixed three bugs that were present in the previous maintenance version (6.4.4). Generally there won't be any new features in a maintenance release.
There is one additional component of the version number that you will sometimes see, and that's the Build number. The first time that we created a version of 6.4.5 for internal development and testing purposes, it was assigned build number 1. That build number is incremented (and unique) for each time that we compile the software. So when Carousel 6.4.5 was officially released to the public, it was build 11. So, the complete version would be Carousel 6.4.5 Build 11. If you participate in a Tightrope Beta test, you will likely receive a few different versions before the software is finally released. Those versions will share the same major, minor and maintenance version, but the build number will be different.
If you ever see an announcement or hear us discuss "Carousel 6.4", that would encompass all of the maintenance versions. As of today, that's 6.4.0, 6.4.1, 6.4.2, 6.4.3, 6.4.4, 6.4.5 and 6.4.6.
You might also hear us refer to these version numbers as 'x.y.z.' This is a shorthand way of describing the same exact concept. In this system, x denotes the major version, y denotes the minor version, and z the maintenance version.
