-## General
+## 概况{#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](/zh/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.
+团队将重点放在内部基础设施工作上，以提高我们的速度，所以在新功能方面，这是一个相当适中的发布。解决了许多错误和较小的问题，并在许多方面提高了整体性能。
 
-## Security
+## 安全{#security}
 
-- **Secure Control Plane Communication**. Mixer and Pilot are now secured with mutual TLS, just like all services in a mesh.
+- **安全的控制平面通信**。Mixer 和 Pilot 现在由双向 TLS 保障安全，就像网格中的所有服务一样。
 
-- **Selective Authentication**. You can now control authentication on a per-service basis via service annotations,
-which helps with incremental migration to Istio.
+- **选择性认证**。现在，您可以通过服务注释在每个服务的基础上控制身份验证，这有助于逐步迁移到 Istio。
 
-## Networking
+## 网络{#networking}
 
-- **Egress rules for TCP**. You can now specify egress rules that affect TCP-level traffic.
+- **TCP Egress 规则**。现在，您可以指定影响 TCP 级别流量的 Egress 规则。
 
-## Policy enforcement and telemetry
+## 策略执行和遥测{#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.
+- **改善缓存**。Envoy 和 Mixer 之间的缓存得到了很大改善，大大降低了授权检查的平均延迟。
 
-- **Improved list Adapter**. The Mixer 'list' adapter now supports regular expression matching. See the adapter's
-[configuration options](/zh/docs/reference/config/policy-and-telemetry/adapters/list/) for details.
+- **改进的列表适配器**。Mixer “列表” 适配器现在支持正则表达式匹配。有关详细信息，请参见适配器的[配置选项](/zh/docs/reference/config/policy-and-telemetry/adapters/list/)。

-We expect to invest more in this area in coming releases.
+- **配置校验**。Mixer 对配置状态进行更广泛的验证，以便更早发现问题。我们希望在即将发布的版本中，投入更多的精力在此功能上。
