Long Time Support / LTS
Long Time Support or LTS is something that will be fully supported for a long time. Usually when there is an LTS release of something there is also another version that has all the progressive enhancements in it as they are stabilized for the next LTS release.
Generally you want the LTS release of something to avoid problems.
The only time you wouldn’t get the LTS release is if you are actively contributing feedback or commits to a project to help it progress.
