+We're pleased to announce that Mesos 1.8.0 is now available for [download](/downloads).
+
+As usual, lots of work and care went into this release, with a total of 255 JIRA issues resolved,
+and 1149 commits containing a total diffstat of 656 files changed, 62213 insertions(+) and 20403 deletions(-).

+
+Looking at the distribution of changes, nearly all components have seen major activity.
+Some of that is presented in more detail below.
+
+One major focus for the 1.8 contributors seems to have been solid test coverage, with
+nearly one third of the total amount of lines changed being inside the test suite.
+
+
+## Highlights
+
+### Allocator Performance Improvements
+
+In Mesos 1.8, allocator cycle time is significantly decreased when quota is
+used; around 40% for a small size cluster and up to 70% for larger clusters.
+This greatly narrows the allocator performance gap between quota and non-quota
+usage scenarios.
+
+In addition, schedulers can now specify the minimum resource quantities needed
+in an offer, which acts as an override of the global `--min_allocatable_resources`
+master flag. Updating schedulers to specify this field improves multi-scheduler
+scalability as it reduces the amount of offers declined from having insufficient
+resource quantities.
+
+Note that this feature currently requires that the scheduler re-subscribes each
+time it wants to mutate the minimum resource quantity offer filter information,
+see [MESOS-7258](https://issues.apache.org/jira/browse/MESOS-7258).
+
+
+### Seccomp Isolator
+
+A new `linux/seccomp` [isolator](docs/isolators/linux-seccomp) was added. This
+isolator makes use of the
+[seccomp](https://www.kernel.org/doc/Documentation/prctl/seccomp_filter.txt)
+facility provided by recent linux kernels.
+
+Using this isolator, containers launched by Mesos containerizer can be sandboxed
+by enabling filtering of system calls using a configurable policy.
+
+
+### Operation Feedback
+
+In Mesos 1.6, operation feedback was introduced for operations on resources
+by a resource provider.
+
+In Mesos 1.8, v1 schedulers can now receive operation feedback for operations
+on agent default resources, i.e. normal cpu, memory, and disk. This means that
+the v1 scheduler API's operation feedback feature can now be used for any offer
+operations except for `LAUNCH` and `LAUNCH_GROUP`, on any type of resources.
+
+
+### Containerization
+
+A number of containerization-related improvements have landed in Mesos 1.8:
+
+ - Support pulling docker images with docker manifest
+ V2 Schema2 on Mesos Containerizer.
+
+ - Support custom port range option to the `network/ports`
+ isolator. Added the `--container_ports_isolated_range` flag to the
+ `network/ports` isolator. This allows the operator to specify a custom
+ port range to be protected by the isolator.
+
+ - Support XFS quota for persistent volumes. Added
+ persistent volume support to the `disk/xfs` isolator.
+
+ - Support an option to create non-existing host
+ paths for host path volume in Mesos Containerizer. Added a new
+ agent flag `--host_path_volume_force_creation` for the
+ `volume/host_path` isolator.
+
+
+### CLI Improvements
+
+The Mesos CLI now offers the task subcommand with two actions. The first
+action, `task attach`, allows you to attach your terminal to a running
+task launched with a tty. The second action, `task exec`, launches a
+new nested container inside a running task.
+
+To build the CLI, use the flag `--enable-new-cli` with Autotools or
+`-DENABLE_NEW_CLI=1` with CMake on MacOS or Linux.
+
+
+### Experimental Features
+
+Mesos 1.8 adds experimental support for the new CSI v1 API. Operators can deploy
+plugins that are compatible to either CSI v0 or v1 to create persistent
+volumes through storage local resource providers, and Mesos will
+automatically detect which CSI versions are supported by the plugins.
+
+
+## Upgrade
+
+Upgrades from Mesos 1.7.0 to Mesos 1.8.0 should be straightforward. Please
+refer to the [upgrade guide](http://mesos.apache.org/documentation/latest/upgrades/)
+for detailed information on upgrading to Mesos 1.8.0.
+
+- Frameworks relying on the experimental `RECONCILE_OPERATIONS` call can
+ not be updated to Mesos 1.8, since the API of that has been reworked in
+ a non-backwards compatible manner.
+
+
