I'm happy to announce that OpenStack Swift 2.8.0 has been released.

This release includes several feature improvements and important
bug fixes, and I recommend that everyone upgrade as soon as possible.
As always, you can upgrade to this version with no end-user downtime.

The full release notes can be found at
https://github.com/openstack/swift/blob/master/CHANGELOG.

The release is available at https://tarballs.openstack.org/swift/.

Feature highlights:

• Concurrent bulk deletes now uses concurrency to speed up the process.
  This will result in faster API responses to end users. The amount of
  concurrency used is configurable by the operator, and it defaults to 2.

• Server-side copy has been refactored to be entirely encapsulated
  in middleware. Not only does this make the code cleaner and make it
  easier to support external middleware, this change is necessary for the
  upcoming server-side encryption functionality.

• The fallocate_reserve setting can now be a percent of drive
  capacity instead of just a fixed number of bytes.

• the deprecated threads_per_disk setting has been removed.
  Deployers are encouraged to use servers_per_port instead.

Bug-fix highlights:

• Fixed an infinite recursion issue when syslog is down.

• Fixed a rare case where a backend failure during a read could
  result in a missing byte in the response body.

• disable_fallocate not also correctly disables fallocate_reserve.

• Fixed an issue where a single-replica configuration for account or
  container DBs could result in the DB being inadvertently deleted if
  it was placed on a handoff node.

• Reclaim isolated .meta files if they are older than the reclaim_age.

This release is the work of 42 different developers, including 16
first-time contributors. That you to the whole community for your work
during this release.
