To save you a click, the actual headline is "Help us test the SQLite implementation", and the news is that WordPress developers are asking (urging!) hosts, plugin authors, and theme developers to test the implementation and report bugs.

The most interesting bit for me: "The SQLite code used has been in use for many years and has been battle-tested. We opted to start with a tried solution instead of starting from scratch because many of the problems we would have encountered have already been addressed and solved in the pre-existing implementation."
