Embedding is lot more friendly than screen captures. You can't interact with a screen captures.

Embedding tweets is nothing new in 4.5. It has just been extended a bit.

For users, 4.5 have enhanced the customizer, it updates faster (somewhat dependent on theme support) and you have the new device preview feature.

Some changes and enhancements under the hood will be benefits in the long run, if not immediately after upgrade.

Expect themes and plugins to gradually adopt the changes made, and make your experience better.

Don't expect WordPress core updates to come with a lot of shiny new features for each release. Just think of WP REST API. Noting to see, but it's still very important in the long run.

But plugins and themes may do a lot of things in a much better way for each core update. WordPress development is trying to prepare for future demands.

WordPress is becoming more like an operating system, like Android, iOS, OSX, Linux or Windows. When they update, you might not see any real and immediate change. But your apps will change and become more powerful over time.
