Version 1.3.1 just released!
Announcement post in Reddit: https://www.reddit.com/r/siacoin/comments/7l41hp/announcing_sia_v131/
Download: https://sia.tech/apps/
Instructions for updating, in case you are not familiar with the process: https://siawiki.tech/client/updating_the_interface
Take in mind this version is including a hardfork for correcting the Difficulty Adjustment Algorithm at block 139.000 (in about 5 weeks), so update your clients before that deadline!
Note: Like the last harfork, this is a non-contentious fork (all the community is accepting it and upgrading), so there will not be a new coin generated. In other words: this is not an "airdrop".
Thanks for the continued hard work!
