This Week in Flynn

The Flynn team continues to focus on production readiness. This past week saw a number of improvements to stability along with some big enhancements.

The Flynn host daemon now supports zero downtime updates. Soon the updater will be able to update entire clusters without downtime.

Logging has been added or enhanced in a number of components to better track down remaining issues.

We also added an FAQ section to the docs to address the most common questions. If you have a question that isn’t answered there, please open an issue.
