Can someone explain to me what the LTS is for. Why does 2019.4 have LTS, where as 2019.3 does not?
My original assumption was that an LTS release should be a stable stream that has been in development and is guaranteed to be essentially the same in the long term.
2019.1, 2 and 3 were technical releases with new features and bug fixes.
2019.4 is 2019.3 but more bug fixes and no new features. And this will be continued for 2 years. No new features but the majority of bug fixes will land in 2019.LTS, so it will be more stable release than 2020.1 for example, where new features will be introduced.
