Should I use the development release or the stable one?

Many active SWI-Prolog users track the development releases or GIT versions for developing Prolog applications. Most of the time the development versions are fairly stable. Infrequent larger rewrites to the core infrastructure that may cause instability is typically announced on the mailinglist.

Tracking the latest version offers some advantages for you are user:

  • Bug fixes are quickly available.
  • When you are stuck on a missing feature you can use this quickly after it has been added.
  • Although you are a little more often confronted with incompatibilities and regressions, such issues can be discussed and resolved.
