The latest update for Sunless Sea is now available to Explorer-level backers via the Humble Bundle download site.

IMPORTANT! Before you do anything else, Check for New Content with the menu button and update your content.

ALSO IMPORTANT! When you're downloading new content, the bar may stick at the end for a while. It's still going - don't cancel! We're working on optimising this - just grab yourself a cup of your preferred hot beverage and it'll be done when you get back.

Meta

You can now update content from the main menu without needing to start a new game
Content updates can now include more substantial changes - you may occasionally see an island move slightly to the left, for instance
Save games can be deleted

Survival

Terror effects are much clearer. Staying near coastlines and light, and leaving your prow light on, will greatly mitigate terror.
Hunger now increases more slowly, but is multiplied by current # of crew
If you have less than half your full complement of Crew, you cannot move at full speed
If you have less than a quarter of your full complement of Crew, loneliness will bedevil you, increasing Terror faster
Fuel is now used more quickly - its use is influenced by Engine Power and by any Fuel Efficiency officers and items
Your Engine Power and the Weight of your ship determines the speed you travel.
Adding extra fuel to your boiler will still increase your speed, but will from time to time cause terrible disasters
Reassigning officers outside port will cause uncertainty, and a small Terror increase.

Content

Shepherd's Wash, with three ports, is now available. The third of these ports contains a teaser for a substantial story written by Emily Short, in a surprise guest appearance... it'll open in the next content update.
The Khan's Heart placeholder is available to visit, although there's only one good reason to do so.
Many more ships are available, although you may have trouble finding engines powerful enough for the largest
Infidelity is no longer rewarded
Numerous lighting and terrain changes
The Genial Magician storyline can now be concluded
Many more content updates have popped since the last major patch - see /sunless-sea-content-updates
