Multiple warnings/errors running either sbt test or sbt console following Zero to Sixty instructions. The ending information below from running sbt (no errors) and then "console" from root directory programming-scala-book-code-examples (used git clone to build the directory)

Thanks for the heads up and sorry I didn't catch these syntax changes. I'll try to fix them today.

Thanks Dean; I really appreciate that you are responding so quickly. Looking forward to adding Scala to my python/pyspark data science tool set and using, where applicable, in the near future. I have no doubt, with your experience and instruction put into your book, that I'm well on my way. Thanks again.

Okay, it's fixed. I had to set the Scala Version to 3.5.2, the last "official" release. It looks like 3.6.X will introduce breaking syntax changes, which I'll support when this series is official, starting with 3.6.2 (There were "glitches" with 3.6.0 and 3.6.1...)

Let me know if you have any more issues!
