I just read through it. It's basically a summary of quite a lot of change happening to quite a lot of products that they ship as Elastic. Each of those products has their own set of release notes; which you probably should be reading if you use those products.

But the executive summary for an ELK user like you:

- Kibana just got faster (finally). I know some people in that team and they completed some internal javascript refactoring that gets rid of the annoyingly long page loads. So, this is a relatively big improvement for a 7.9.

- Elastic Agent is a new thing that can get a lot of data into dashboards quickly. That might be relevant for you if you have a (no doubt) lovingly handcrafted logstash ingestion pipeline and matching dashboards. Also, setting up half a dozen elastic different beat agents to achieve the same was definitely a bit of a devops burden. Sounds like something I might give a try next time I set up new infrastructure.

- You can now self host Elastic Cloud in your own AWS infrastructure. This may be relevant for you if you were self hosting some home grown setup on premise (or in aws) or are using the fully managed cloud solution. Kind of a big deal for more advanced setups as a lot of companies get themselves into trouble with getting their homegrown devops for this right.

- A lot of updates to Elastic products neither you nor me use. The workplace search thing sounds interesting though. Wasn't really on my horizon so far.
