March 13, 2019 update: WordPress 5.1.1 released.
Yesterday, March 12th, WordPress released version 5.1.1, which is a security release fixing issues in 5.1 and earlier.
The original version of this article stated that versions prior to 4.9.9 should not be used. With the 5.1.1 security release, WordPress has now also released secure versions as far back as the 3.9.x branch. We encourage you to update WordPress to the latest version, though, for enhanced security and functionality, including the new block editor, introduced in WordPress 5.0.

It’s always important to keep your WordPress software, plugin, and themes up to date. Keeping WordPress updated is the top way to keep your website safe. WordPress 5.0.1 was released in December 2018, so don’t delay any longer in updating your WordPress website.
