It would be nice to have the livestream be free, even if it contained sponsorship ads to cover the cost.

or maybe even post the videos on YouTube the next day?

The Livestream Pass gives you live access + immediate access to the recordings afterwards. At $350 it's a pretty reasonable ask of your employer.
I think the session recordings go up for free to the public early next year.

Damn, 8.3 must be good !

If they find value in it, yes.
Waiting like 4+ month to post the videos is kind of weird.. I can't calculate the logic to that.

I'll try to make a youtube video asap on the new changes, keep you posted.

Some main points, I'm sure I've missed some.
- New Gateway webpage design
- Perspective drawing tools (mimics Inkscape) - with bindings
- Forms
- Perspective offline (for things like forms)
- Event streams (pipeline from sources to handlers)
- Power historian
- Everything now in filesystem (JSON), no internal database. Gives source control compatibility
- Deployment modes, makes test/production environments easier

With bindings INSIDE. Don't forget the best part.

Pfffff I can't wait
Yes, I'm really pleased with how the architecture is shaping up. Lots of pain points going away.

Public beta expected to begin in December. Mid January release.
All purchases now with support plan will upgrade to 8.3 free.

It seems some of the finer details are being worked out but it looks really good.
Power historian is the new time series data collection built on Quest DB. They said something about it being able to do almost 2 million data points per second with zero configuration. Later another person talked about testing it with 4k data points and said it was easily able to handle that. I think the 2 million number was a benchmark test or something. Whatever it is, it's a lot faster than writing to a database because it's local to the gateway. I suspect the performance would be based on what drive you are writing your data to.
You can configure automatic archiving as well. Various people spoke with IA staff about being able to move where power historian stores its data. It sounded like something they could do but they didn't commit to it for initial release.
You can connect to the Power Historian data using a Postgress db connection.
It sounded like the power historian does not support redundancy at least in the initial release.
New alarm aggregation system that creates properties on folders and UDTs that you can bind to for alarm statistics within the folder.
The test mode was interesting. You can set up things like database connections to have a test mode connection and a live mode connection. Changing what mode you're in requires a gateway restart. So you can test your screens and then when you deploy them to the live environment you don't have to go through and change the connection being used in the code. Very nice.
There's a new mechanism called "Event Streams" which has to do with piping information to external consumers. Sources mentioned for initial release were HTTP, Kafka and Event listeners. New Kafka service connector. They will be adding more support in the future. They said they do things in 2 phases. First make it possible. Then make it easy.
Gateway backups will be able to select what components to include in the backup.
New "secrets management" system that allows you to separate things that involve sensitive information from the rest of the project.
Gateway Configuration website completely redone with Rest API support. Everything organized to make it easier to get to things quickly. Search feature lets you search for specific things.
Forms is a pretty hard feature to explain. It's a new component you can put on a view that has boiler plate controls on it and passes data back through the event stream. This can be used in conjunction with offline mode. I think they said you have to start a visualization client in offline mode to use it but I might have heard wrong. Offline mode lets you run a perspective app and build up data in the event stream to send to the gateway when you're back to a stable connection.
They talked a little bit about containerization support but I can't say much about that. My notes are a little spotty on that. I think that had to do with Helm charts and kuberentes platform for cloud config.
Native Twilio and whatsapp support.
Quick launch for Ignition clients from gateway page.
There's more but that's a lot of it.

That was with regard to offline mode, not necessarily with forms. The app won't automatically switch between online/offline modes, but if you need the forms in an offline mode (or any STATIC views for that matter), you have to explicitly launch the app from Perspective workstation in offline mode. To go back online and sync offline data, you have to launch it in online mode afterwards.

Unit typo?
No, I believe the almost 2 million was directed at benchmarks, but the 4k points was a small test the speaker did to test performance of running trends at the same time as injesting new data. I don't think he had 4k points on the trend, but was just saying even while injesting 4k points per second the trend was still populating quickly.

I'm doing ICC virtually. Was this explained in the live keynote, or on the side? I don't remember hearing about this. But, that's a nice feature.
I think the Alarm stats was in the main keynote because it's in that part of my notes.

It was in one of then live sessions. And wasn't covered in depth. Just a brief mention.
Apparently alarm stats data at folder level and UDT tag level.
