A build of the software has a version number, which looks something like 1922.23.253. In this example, 1922.2 3 is the major version, and 253 is the build number.

The major version looks something like 1922.5 2 or 2022.1 3 or 2023.31. The 19 22 or 20 23 represents the year in which the version was released, and number after the “.” increments with each new major version released over the year.

The build number increments each time Alastri creates a new build. The build number increments globally across all versions, so it’s possible build 450 is for version 2023.1, while build 451 is for version 1922.43. Essentially the build number is a unique id of the build.

...

Upgrading from the major version to a later build of the same major version will almost always not require any changes on your part. As an example, you can open version 1822.43.242 and upgrade to 1822.43.278, and this will likely not require any changes on your part. When changes are required, it is because there was a bug which requires minor alterations to the model setup. As an example, there might be a bug which allowed the user to set up the model in an invalid way, and once that bug is fixed, the user will be required to fix the setup.

Info

Upgrades are One-Way

While you can upgrade a model from an old version to a new version, it is not possible to open a model saved in a newer version in an old version of the software. Therefore, before upgrading it’s it is recommended to save a backup.

...

Alastri’s products are built to work together, but this is only possible if they’re all of the same version. Therefore, when upgrading one product to a specific version, you must upgrade the others to also be on the same version, if you wish to use them together. For example, if you upgrade RR to 2022.2.152 and you want to use the output with APS, you need to upgrade HI to 2022.2.152 and APS to 2022.2.152. Then, if you want to use the output from APS with SC, then that will need to be on 2022.2.152 as well.

An outcome of the above is that you should also work on the same version as the others you are working with, so the team as a whole needs to choose a specific version to work with.
