Polaris v1.11.3 Release: Enhanced Rate Limiting, Upgrade Steps & Contributor List

Overview

Polaris (PolarisMesh) is a cloud‑native service discovery and governance platform supporting multiple languages and frameworks. Version v1.11.3 adds enhancements to rate‑limiting, configuration management, and overall stability.

Main Rate‑Limiting Changes

Rate‑limiting rules are separated from service information into an independent feature section.

Five matching calculation methods are supported: exact, regex, not‑equal, contains, not‑contains.

Request‑matching rule keys are categorized by source: header, query, caller service, caller IP, and user‑defined parameters.

Other Server Improvements

Added a test‑environment routing guide in the dynamic routing feature.

Configuration center now supports template‑based config generation (PR #526). URL: https://github.com/polarismesh/polaris/pull/526

Server error messages are internationalized (PR #550). URL: https://github.com/polarismesh/polaris/pull/550

Refactored and optimized configuration center code (PR #553). URL: https://github.com/polarismesh/polaris/pull/553

Fixed bug where single‑node version updated instance timestamps without operation, causing continuous SDK update events (PR #527). URL: https://github.com/polarismesh/polaris/pull/527

Improved compatibility for Eureka heartbeat error codes (PR #670). URL: https://github.com/polarismesh/polaris/pull/670

Polaris Console Updates (v1.8.1)

Automatic file‑format detection when creating configuration files.

Adjusted card body height to fill the browser window.

Optimized service instance add/edit forms.

Fixed bug where deleting the last circuit‑breaker rule did not trigger unbinding.

Polaris K8s Controller Updates (v1.3.0)

Supports deployment on Kubernetes v1.22+ as well as versions below v1.21.

Provides an mtls switch to enable Envoy mtls capability (beta).
