unity editor update,unity editor version update

I have Installed 2021.3.0f1. within few days 2021.3.1f1 version got released. when selected check for update it shows its up to date. I can’t update the editor. both shows LTS. I saw the same question asked in 2014. any way to .update than manual download available now.? Also should i also download android support again?,

The last number means a minor hotfix so you don’t absolutely need to download it but if you want to then you download it just the same.

If you’re asking if its possible to do a smaller download and just update that version you already have, I don’t believe that’s possible, you need to download the entire new version
