Wayfinder's Guide Update - what's changed?

[Chaosvii7]

Got an email that the Wayfinder's Guide has updated, specifically its rules about Dragonmarks. I know they recently put out the Dragonmarks in UA to get feedback to improve them - an article that was actually missing part of its content as part of a mark was cut and pasted into the description of another - but I've looked through three versions of the guide and all I've found different between them is that only Half-Orcs can use the one mark they got access to. Is that it, or am I missing something else in this section that's passing me by? Has anyone started to look through their updated guides to see if they can figure out what, if anything, is new?

The discussion on the site lists the changes. Seems finding was made half-orc only, a typo between storm and detection was corrected, healing got spare the dying.
