Apple today seeded the fifth beta of an upcoming macOS Mojave 10.14.5 update to developers for testing purposes, one week after releasing the fourth beta and more than a month after the launch of macOS Mojave 10.14.4.
The macOS Mojave 10.14.5 beta can be downloaded through the Software Update mechanism in System Preferences after the proper profile has been installed from Apple's Developer Center.
It's not yet clear if there are new features in macOS Mojave 10.14.5, but it likely includes bug fixes and performance improvements to address issues that weren't able to be fixed in the macOS Mojave 10.14.4 update.
This update will make macOS more secure because after macOS 10.14.5, new Mac apps released outside of the Mac App Store that want to have Apple's seal of approval will need to go through Apple's notarization security process.
The prior update, macOS Mojave 10.14.4, brought the Apple News+ subscription service, expanded Apple News to Canada, and introduced a new automatic Safari Dark Mode feature for websites.

The problem as commonly reported is that mail takes the gmail account(s) offline after some period, roughly an hour to a few hours. It won't work again until you quit mail and then restart it, after which the cycle repeats.
I really want this to be the case. I've seen so many people incorrectly declare it "fixed" (if you just jump through ineffective hoops x, y, or z) that I'm skeptical. Have you seen anything from a credible source that indicates Apple even acknowledges the problem? Or, were you personally experiencing the problem and see it corrected in the beta?
Definitely can reproduce it by leaving mail open. Looks to be around 90 minutes for me.
Interesting thing is it doesn’t reproduce under parallels. So my guess is an issue with WebKit. But I’m outside my comfort zone on this.
I did file a bug with feedback for it. And full steps to reproduce.
Load mail. Close to dock. Ignore mail for 90 minutes + etc...
thanks for posting More thoroughly. This really was the first time I saw someone say they left it open.
My suggestion to all here is anyone running the beta report a bug and clearly state how LONG mail was open.
Bet guess from me is something to do with a dormant port tripping an error or security setting, either on the user end (mail) or at gmail. But I simply don’t know enough on my own.
I have seen a couple of "offline" symbols, but clicking the get new mail button always takes it back online and gets the mail. I have been sleeping the machine with mail running too. It's beyond me why Jose's workaround changes the mail app behavior with regard to gmail connections but it does.
Now mail is tolerable to use again. Whatever change Apple made to 10.14.4 mail had an inscrutable side effect that continues to plague a significant number of gmail users. Given these weird symptoms it must be very difficult for Apple to identify.
