The State of Guile

Guile 1.0 was released in 1997. Being built upon an existing Scheme interpreter, its first release came relatively speedily after the initial announcement of the project.

Speaking as one not party to the behind-the-scenes details of the development of Guile, it appears that it has been a project where momentum has waxed and waned. Currently, the project is being actively developed, and the point releases are regular occurrences.

The current stable branch of the code is 1.6.X, and this book is based on the API in the 1.6.X branch.

Because Guile itself is under active development, applications built on the framework may be affected when new versions of Guile are released. One should refer to The GNU Guile page for the latest news on its release schedule.

I can only guarantee that the examples in this book with Guile 1.6.4. With other versions, your mileage may vary.

I like the project. I hope the book will help explain why it is great and worth the investment necessary to learn it.
