The Stardew Valley 1.6.4 update is now live on PC and it is surprisingly beefy, including new content, balance changes, visual improvements, fixes, and gameplay tweaks.

The 1.6.4 update was announced on April 10 with virtually no detail, as is the Eric Barone way, except that it would include “a new fishing thing, and some new mining-related stuff” and was expected to be ready “sometime next week,” which of course is now this week.

The mine stuff includes 20 new “alternate” mine layouts and 20 new volcano mine layouts, which appear after you've met certain conditions, while the fishing thing is a “fish frenzy,” which I assume means something like a group of piranha going bonkers, minus any actual deboning of cows—this is Stardew Valley, after all.

There are also four new “fairy styles,” a new cutscene that will play after you've helped your new neighbors expand their family, space for eight additional non-fish items in fish tanks, and more options in the Raccoon Shop. The Chinese, Russian, Portuguese, Hungarian, Turkish, and Korean translations of the game have undergone edits, and there are numerous fixes for mod makers and users.

One of the more interesting items in the patch notes (for me, at least) is the addition of “two inappropriate names to the list to exclude from the name generator.” Call me a Nosy Nelly if you will, but I am really curious what those names are.

Other bits in the patch notes, quite frankly I just do not understand, but I'm glad everyone is having fun.

No one can accuse Barone of goofing off since the release of the big 1.6 update to Stardew Valley that landed in March, but some players are wondering about the status of 1.6 on consoles, which is still pending. Barone said earlier this month that work on the 1.6.4 update “will not slow down the console release” of the 1.6 update, nor will it have any impact on the mobile version, but there's been no further word on when they'll be out.

The full Stardew Valley 1.6.4 patch notes are below.
