It can be hard to keep up with all the changes within the Power Platform. There are so many releases and so many new features arriving all the time.
You can find these releases using the following URL:
Power Automate releases
For Power Automate the different schedule for the different location inn the world and the different releases are all listed with scheduled release dates.
I also noticed that soon we will get Power Automate Mobile releases. Something interesting to look forward to.
Power Apps releases
For Power Apps there is a similar list of releases available and all updates included in any of the releases can be found here too.
A nice little overview especially when you find something that suddenly stopped or started working.
