## General
|
|
|
|
Starting with 0.3, Istio is switching to a monthly release cadence. We hope this will help accelerate our ability
|
|
to deliver timely improvements. See [here](/about/feature-stages/) for information on the state of individual features
|
|
for this release.
|
|
|
|
This is a fairly modest release in terms of new features as the team put emphasis on internal
|
|
infrastructure work to improve our velocity. Many bugs and smaller issues have been addressed and
|
|
overall performance has been improved in a number of areas.
|
|
|
|
## Security
|
|
|
|
- **Secure Control Plane Communication**. Mixer and Pilot are now secured with mutual TLS, just like all services in a mesh.
|
|
|
|
- **Selective Authentication**. You can now control authentication on a per-service basis via service annotations,
|
|
which helps with incremental migration to Istio.
|
|
|
|
## Networking
|
|
|
|
- **Egress rules for TCP**. You can now specify egress rules that affect TCP-level traffic.
|
|
|
|
## Policy enforcement and telemetry
|
|
|
|
- **Improved Caching**. Caching between Envoy and Mixer has gotten substantially better, resulting in a
|
|
significant drop in average latency for authorization checks.
|
|
|
|
- **Improved list Adapter**. The Mixer 'list' adapter now supports regular expression matching. See the adapter's
|
|
[configuration options](/docs/reference/config/policy-and-telemetry/adapters/list/) for details.
|
|
|
|
- **Configuration Validation**. Mixer does more extensive validation of configuration state in order to catch problems earlier.
|
|
We expect to invest more in this area in coming releases.
