A couple of differences/issues in 2018.1

After upgrading from Unity 2017.4 to 2018.1, there are a couple of small things that are different. Curious if I should consider these bugs, merely changes, or things I can change with settings.

• When pressing Ctrl-P to enter play mode, Unity no longer gives any visual indication that it's starting Play mode. In 2017.4, the Play button would immediately look like it was pressed, so I knew that Unity had received my request to play. A second or two later, the game would play. Under 2018.1, however, pressing Ctrl-P causes no visual change until the game is really in play mode. This has caused me to think that I just didn't hit Ctrl-P properly.
• At the bottom right corner, I almost constantly have an empty light baking progress bar, even when no lighting is being baked, and when Auto Generate lighting is off. This just sound more like a bug...
• Under 2017.4, I could write the following into a script: `StartCoroutine(MyRoutine())`; If MyRoutine didn't exist, intellisense would prompt me to create the method, and would properly create MyRoutine with a return type of IEnumerator. Under 2018.1, the method it creates is of type String instead.

Anyone have a sense of whether each of these is a bug I should report, or whether some of these can be resolved through some settings changes?

 

Looks like this is fixed in 2018.1.5.
