I was a bit disappointed to see that there was nothing in the update to make the dagger an alternative to shortswords for finesse melee characters, rather than a downgrade. It's nice that it deals both slashing & piercing damage now, but shortswords getting the same treatment just means the status quo is intact.
I understand that it is hard to improve the dagger much while keeping it on par with other simple weapons, but the chance of a finesse melee character not having martial or rogue proficiency being basically non-existant means that the shortsword is always sitting there as a superior choice, which I feel is a shame considering how iconic the knifefighter archetype is.
(As a side-note, it feels rather unfortunate for Assassins too since presently they do have a reason to be fighting with knives, which makes it rather easy to presume OOC-ly that any character using them is one.)
