Yeah, the message (on completion) says it's a security update, yet the Security "Patch level" is still July 1. The only versioning info that changed was the "Build", going from build NCL26.118-23 to ....118-23-1 So, it's probably bug fix(es) to the previous release that couldn't wait for the next regularly scheduled patch release. That's just my "assumption" and best guess based on previous (to Retirement) software development experience (and not based on any concrete or inside info)
