It’s been exactly one year since we have released version 1.0 of the Stratospheric book.
The book already has 900 readers on Leanpub. Let’s make it 1,000 this month!
We want to celebrate the anniversary with you by releasing version 1.8 of the book and doing an anniversary sale.
You can read more about the new release in this blog post on the Stratospheric website.
