Apple today seeded the fifth beta of an upcoming macOS Sierra 10.12.5 update to developers, one week after seeding the fourth beta and more than one month after releasing macOS Sierra 10.12.4, which introduced Night Shift for the Mac.
The fifth beta of macOS Sierra 10.12.5 can be downloaded through the Apple Developer Center or through the Software Update mechanism in the Mac App Store.
According to the release notes accompanying the beta, the update "improves the stability, compatibility, and security of your Mac."
Apple's release notes don't often provide much insight into what's included in new beta software, so we don't know what features or bug fixes might be built into the 10.12.5 update.
No notable changes or major bug fixes were discovered in the first four betas, but should anything pop up in the fifth macOS Sierra 10.12.5 beta, we'll update this post.
Update: The fifth beta of macOS Sierra 10.12.5 is also available for public beta testers.

This machine was bought as a new 'maxed out' top-end monster.
(It was coincidentally rebuilt from the keel up under AppleCare about a year ago giving me a new screen, motherboard and SSHD following some strange power cut outs.)
It handles everything I throw at it and has no OS drag... Yet.
Look after the Mac and it will look after you!
In life, I've found that you don't always need the shiniest and newest of everything all the time...
Nobody really uses 'all' of the features on their computers either due to Incompatibility, Third Party options, or just no interest/purpose.
10.4 released April 2005
10.5 released oct 2007 (30 months later)
10.6 released Aug 2009 (22 months after 10.5)
10.7 released july 2011 (23 months after 10.6)
It wasnt until 10.8, released july 2012 that Apple started releasing mac os updates on a yearly basis - around the same time a lot of people feel that apple's quality control and software stability took a dip.
IMO, their insistance on rushed annual releases of new OS's has contributed to that decline.
