Soto v5 has just been released and along with a new version of Soto comes a new website. The idea is to have this as a place for more documentation and updates related to Soto. Checkout the user guides for help with specific sections of Soto. There will also be a blog that includes updates about Soto and related projects. On top of this first post there is already another two, one detailing changes in v5 and another on upgrading from v4 of Soto to v5.
