# Release Notes
## Summary
**v3.3.1** introduces significant enhancements to the **Triple protocol**
(including experimental HTTP/3 support), stability improvements for
**Configuration & Registry centers** (Nacos, Apollo, Zookeeper), and major
**refactoring and performance optimizations** of the core modules. This release
also includes adaptation for Go 1.24.
### 🚀 New Features
#### Triple Protocol Enhancements
* **HTTP/3 Support**: Added experimental support for HTTP/3 in the Triple
protocol (#2916).
* **Dual Protocol Concurrency**: Supported starting both HTTP/3 and HTTP/2
servers simultaneously (#2972).
* **Generic Call**: Added support for generic calls in the new Triple
protocol (#2818).
* **Non-IDL Mode**: Supported Non-IDL mode for the new Triple implementation
(#2858).
* **TLS Updates**: Implemented new Triple TLS configuration (#2852) and
redesigned the TLS API (#2891).
* **OpenAPI**: Added tooling support to generate OpenAPI documentation for
the Triple protocol (#2951).
#### Configuration & Registry
* **Apollo Support**: Added support for the Apollo configuration center
(#2857).
* **Nacos Improvements**:
* Fixed an issue where Nacos weights did not work (#2937).
* Resolved Nacos instance overwrite issues (#2882).
* Fixed an issue where new services were not detected during
subscription (#2859).
* **Zookeeper Improvements**: Optimized the distinction between empty and
non-existent nodes, and downgraded empty node error logs to Warn level (#3059).
* **Hot Loading**: Implemented configuration hot-loading capability (#2992).
#### Observability
* **OpenTelemetry**: Upgraded OTel dependencies to v1.21.0 (#2971), adjusted
Trace Scope names to align with OTel specs (#3041), and added an `Insecure`
option to tracing configuration (#3028).
* **Service Logging**: Implemented logging for the service registration
process (#3043).
#### Other Features
* **Go Version**: Updated Go version support to 1.24 and removed deprecated
`rand.seed` usage (#3046).
* **Router API**: Exposed Router-related APIs (#3066) and allowed
group/version wildcards for exact interface matches (#3080).
* **Tooling**: Added an `imports formatter` tool (#3019) and integrated it
into CI checks.
### 💡 Refactoring & Improvements
* **Config Decoupling**: Massive code refactoring moving dependencies from
the `config` package to the `global` package or protocol-specific
configurations to resolve circular dependencies (affecting registry, filter,
tls, graceful_shutdown, etc.).
* **Logger Refactoring**: Refactored the logger module (#2838) and added
comprehensive unit tests (#2993).
* **Makefile**: Completely rewrote the Makefile to improve the build
experience and standardization (#2975).
* **CAS Optimization**: Replaced deprecated CAS operations with
`CompareAndSwap` (#2962).
* **Graceful Shutdown**: Added timeout control for Triple protocol graceful
shutdown (#2943) and utilized `errgroup` for handling stop errors (#2973).
* **Memory Optimization**: Resolved memory leaks in Goroutine management,
file handles, and extension caches (#3023).
### 🐛 Bug Fixes
* **Stability**:
* Replaced panic with error handling for cluster extension failures
(#3021, #3064).
* Fixed logical dead loops (#2879).
* Fixed URL parameter loss in the `SetParams` method (#3022).
* **Triple/Communication**:
* Fixed issues where clients failed to receive attachments from server
responses (#2928, #2854).
* Fixed Context Attachment error handling in Triple protocol streaming
calls (#2810).
* Fixed read prefix EOF errors (#2912).
* **Logging & Misc**:
* Fixed incorrect log rotation paths to prevent file loss (#3014).
* Changed log level from Error to Warn when application parameters are
empty in Tag Router (#3035).
* Fixed latency issues in Zookeeper client node perception (#2930).
### 📚 Documentation & CI
* **CI Enhancements**: Added `make check-fmt` (#3055), License header checks
(#2957), and import-formatter checks (#2961).
* **Docs Updates**: Updated README contact info, fixed invalid links in
README_CN, and updated `protoc-gen-go-triple` documentation.
* **SonarQube**: Fixed and suppressed various SonarQube/SonarCloud false
positives and AI bot warnings.
