**Type:** Announcement

## Summary

This Fly Changelog records significant changes to the Fly platform, tooling, and websites for the week of 29 May 2020. flyctl 0.0.124 adds apps pause and apps resume commands, which remove all running instances or start one running instance, respectively; regions set replaces the regions in a region pool list; and -v/--verbose provides more detailed command output. The release also improves flyctl apps list by displaying each application's status, while the Deno Buildpack supports unstable Deno builds when an .unstable directory is added to the application directory. Earlier in the month, flyctl 0.0.123 introduced open, which finds a deployed application's hostname and instructs a web browser to open it.

## Context

The changelog lists significant weekly changes to the Fly platform, tooling, and websites, including new application pause and resume capabilities, faster application access, and updates to the Deno Buildpack.

## Approach / What changed

flyctl 0.0.124 adds commands for pausing and resuming applications, replacing regions, enabling verbose output, and viewing application status. The Deno Buildpack enables unstable Deno builds through an .unstable directory, while version 0.0.123 added the open command.

## Takeaways

- flyctl apps pause removes all running instances of an application, while flyctl apps resume starts one running instance.
- flyctl regions set completely replaces the regions in the region pool list, and -v or --verbose produces more detailed output where supported.
- The Deno Buildpack supports unstable Deno builds when an .unstable directory is added to the application directory.
