They posted this a few hours ago, i've always been impressed with this app, big improvements.
Thanks! Almost every aspect of the app got a rework in this version.
Not really upset about that, but rather the fact that they sold it as a full product and made ZERO mention of a subscription based model for part of that same application I paid for.
iStat Menus 6 includes a 14-day free trial, and 6 months of weather data is included in the initial purchase. We use premium data sources, and we have to pay for usage every time weather is fetched. There really isn’t an alternative in terms of weather data sources, if you’re after something free, high quality, global, and with a license that allows commercial use.
We have some more info on the topic here:

I'm guessing it was required to license the Dark Sky data? But yeah, pretty bizarre (and all the more reason to add other providers).
We’ll definitely consider adding other providers in the future. We’re using Weather Underground for some locations.
Yes, I went with the upgrade as I've bought every prior iStat version. I've just got a personal preference not to purchase subscription based software. They should of made it clear that part of the application requires a subscription and I'd of gladly stayed quiet and stayed with the current version.
I don’t like subscription software either. We pay for weather data fetching based on each request, so we wanted something that aligned with how we get charged. Please note that weather in iStat Menus is sold as data packs that cover 12 months — they never auto-renew and there is nothing to cancel, if you decide you do not want it any more. It’s a subtle difference, but I think it is an important one.
No sooner do I type, another email comes in with the serial. Whew!
Great to hear.

Thanks for your patience. There’s been some delays in the second emails (the important one with the license in it!).
I was using 5.X on macOS 10.12.6 and it automatically installed 6.0 (in truth, it probably asked me to update and I probably just said go ahead thinking it was just bug fixes).
The exact window you would have seen can be found here:
https://bjango.com/help/istatmenus6/update/
However, then it popped up a window saying it needed to install "some components" but that fails every time with the helpful message "an error occurred". So I had to download and re-install 5.X. Turned off automatic update check.
Please redownload the latest build:

If that does not work, please get in contact via private message here, or via our website, or via Twitter (public or DM). Thanks!
Upgraded. I use it on all my machines-- $10 to keep the developer going is a pittance.
Thank you! It is appreciated. As long as people keep buying it, we’ll keep making it.
I wish they hadn't included the weather module though. I guess they feel they need to keep adding features to justify the upgrade price, but weather requires pretty specialized presentation. So far, I find ForcastBar has the best presentation, but the actual weather accuracy is crap so it's pretty-but-wrong.
What don’t you like about the way iStat Menus displays weather info? We’re always open to feedback, and want iStat Menus to be the best.
Does anyone have iStat Menu 6 reporting higher RAM usage than iStat Menu 5?
This is very likely due to the settings. Memory pressure vs traditional UNIX memory reporting, or “Hide inactive memory”. We added the ability to control what’s shown in the menubar per item. Here’s where the settings are now:
