Hot on the heels of NetBSD 10.0 comes NetBSD 9.4, a minor release in the previous release branch.
NetBSD 9.4 is primarily a bug and security fix release, however, there are some new features, such as support for more MegaRAID controllers, ZTE MF112 and D-Link DWM222 USB 3G modems, and improved CPU feature detection for newer AMD/Intel devices. All users of netbsd-9 should upgrade if they are not following the stable branch.
NetBSD 9.4 release announcement
A very important note here is that the version of OpenSSL in NetBSD 9.4 is no longer supported unless you have a support contract with OpenSSL. They suggest upgrading to NetBSD 10.0, or to use OpenSSL from pkgsrc.
