Not really errata but a suggestion for the next version:  It would help
if there were flow charts or something similar shown to illustrate how
example programs operate.  Seems like a logical step to diagram how the
problem will be solved before jumping into coding.

Good suggestion. Tnx.

Table of contents is correct in the book, but wrong on the errata page. 
Chapter 11, Abstract Members is now Chapter 20 in my copy of the third
edition.

A compilation of the real errors and their correction would be helpful
and time saving. In the current lists, there are redundant comments or
comments not describing errors. This is confusing.

While it's great that readers can supply errata, it is not entirely clear
when an item is simply one reader's opinion, possibly erroneous itself,
as contrasted with an item that has received some editorial scrutiny. Can
we have some indication of which items have been blessed by the authors
or other qualified people, and which are simply raw input from somebody
like me, who has little knowledge of Scala.
