The Japanese translation team for Katawa Shoujo will be returning to Comiket this year, and hard copies of the game will be available for purchase at their table. If you can get to Tokyo Big Sight on Sunday, August 16, consider checking out Comiket 88 and heading over to east hall 2, space T-30a.
Four Leaf Studios announced on their official blog a couple of weeks ago that version 1.3.1 of Katawa Shoujo has been released. This update contains several script updates for the Japanese translation, and is available for free download for Windows, Mac and Linux at their official website. This will be the finalr release of the game; official support for it has ended. Four Leaf Studios will still be contactable via email, social media, forums and IRC.
