I don't know the correct place for this question so I'm asking here: I have a previous version of Blender that I downloaded but was never able to use (extended illness). I would now like to download the current version and would like to know what the latest version is and I'd like to know if I have to delete the version I already have. Thank you.
You Can keep the current version but it's quite useless.
There are three current builds:
- the main: 2.78c that you can download from the official website under download.
The last two are for advanced users they are unstable, so do not save any important file with this versions:
- 2.79 testbuilds (2.78.5), downloadable from here:
- 2.8 Testbuilds (2.8), downloadable from here:
https://builder.blender.org/download/ under the red rectangle (2.8 project)
If you go to https://www.blender.org/download/ you can get the latest release version.
You don't need to uninstall previous versions you might have in your system.
