"ERR LC.V: New license type is not supported prior to 5.3"

You may see the following license error:

2018-10-03 12:50:58.439805 [NOTICE] Memory size is: 8388608KB.
2018-10-03 12:50:58.633518 [ERROR] [LICENSE] License key operation failure: ERR LC.V: New license type is not supported prior to 5.3.

8GB of memory meets the license requirement, so what is this error about?

The new license types introduced in September 2018 not only have RAM requirements but also _must_ be using LSWS 5.3 at a minimum. If you are still running LSWS 5.2.x or earlier, but have ordered a new license type, you may see the above error. Upgrading LSWS to the most recent version should fix the error.
