 Users need to record the LLM model of client requests that are not modified by the gateway when logging AI proxy requests, so a new context variable `request_llm_model` is added to record it.

 This PR enhances APISIX's SSL SNI matching capability by adding support for complete wildcard (`*`) values. Previously, APISIX only supported exact domain matching (e.g., `abc.test.com`) and partial wildcards (e.g., `.test.com`), but lacked support for the universal wildcard.
 This addition ensures compatibility with the Gateway API's HTTPSListener specification, meeting its core consistency test requirements for handling SSL connections with wildcard server name indications.

 This PR introduces a validate API to standalone mode. The validate API checks the configuration input without saving it to memory. It allows the APISIX Ingress Controller to verify the CRD-converted plugin configurations before applying them, preventing runtime failures.

+
+## Introduction
+
+From its inception, the Apache APISIX project has embraced the ethos of open-source community collaboration, propelling it into the ranks of the most active global open-source API gateway projects. The proverbial wisdom of 'teamwork makes the dream work' rings true in our way and is made possible by the collective effort of our community.
+
+From December 1st to December 31st, 18 contributors made 45 commits to Apache APISIX. We sincerely appreciate your contributions to Apache APISIX.

+
+## Feature Highlight
+
+### 1.Add Global Default `path` Property to `file-logger` Plugin Metadata
+
+PR: https://github.com/apache/apisix/pull/12825
+
+Contributor: [TaeyeongKwak](https://github.com/TaeyeongKwak)
+
+This PR introduces a path property to the `file-logger` plugin's metadata, allowing a default log file path to be configured globally via `plugin_metadata`. This default will be used by `file-logger` instances that do not explicitly define their own path in their configuration.
+
+### 2. Add Nested Log Format Support for Logger Plugins
+
+PR: https://github.com/apache/apisix/pull/12697
+
+Contributor: [TaeyeongKwak](https://github.com/TaeyeongKwak)
+
+This PR adds support for nested (hierarchical) data structures in the `log_format` configuration of logger plugins. Previously limited to flat key-value pairs, users can now organize and group log fields more efficiently by defining hierarchical log structures.
+
+### 3. Add Protocol Validation and Deletion Protection for Stream Routes
+
+PR: https://github.com/apache/apisix/pull/12794
+
+Contributor: [yixianOu](https://github.com/yixianOu)
+
+This PR introduces dependency validation and deletion protection for stream routes.
+
+- When creating a subordinate route referencing a `superior_id`, the system now verifies that the superior route exists and that protocols match.
+- Implements a `delete_checker` that prevents the removal of any stream route that is currently referenced as a `superior_id` by other routes.
+- Adds a new test file `t/admin/stream-routes-subordinate.t` covering creation, protocol mismatch, and deletion‑protection scenarios.
+
+## Conclusion
+
+The [official website](https://apisix.apache.org/) and [GitHub Issues](https://github.com/apache/apisix/issues) of Apache APISIX provide a wealth of documentation of tutorials, and real-world use cases. If you encounter any issues, you can refer to the documentation, search for keywords in Issues, or participate in discussions on Issues to share your ideas and practical experiences.

+## 近期亮点功能
+
+### 1. 为 `file-logger` 插件元数据添加全局默认 `path` 配置
+
+相关 PR：https://github.com/apache/apisix/pull/12825
+
+贡献者：[TaeyeongKwak](https://github.com/TaeyeongKwak)
+
+本 PR 为 `file-logger` 插件的元数据新增了 `path` 属性。通过 `plugin_metadata`，用户可以全局配置一个默认的日志文件路径。当单个 `file-logger` 插件实例未在其配置中明确定义自身路径时，将自动使用该全局默认路径。
+
+### 2. 为日志插件添加嵌套日志格式支持
+
+相关 PR：https://github.com/apache/apisix/pull/12679
+
+贡献者：[TaeyeongKwak](https://github.com/TaeyeongKwak)
+
+此 PR 为日志插件的 `log_format` 配置新增了对嵌套（层级式）数据结构的支持。此前，日志格式仅支持扁平的键值对结构；现在，用户可以通过定义层级式或可重叠的日志结构，更有效地组织和分组日志字段，从而获得更清晰、更具结构化的日志输出。
+
+### 3. 为 Stream Routes 添加协议验证与删除保护
+
+相关 PR：https://github.com/apache/apisix/pull/12794
+
+贡献者：[yixianOu](https://github.com/yixianOu)
+
+本 PR 为 Stream Routes 引入了依赖验证与删除保护功能。
+
+- 现在，当创建引用 `superior_id` 的下级路由时，系统会验证所引用的上级路由是否存在，并确保它们的协议一致。
+- 实现了一个删除检查器，防止任何当前被其他路由引用为 `superior_id` 的 stream route 被删除。
+- 新增了测试文件 `t/admin/stream-routes-subordinate.t`，涵盖了路由创建、协议不匹配以及删除保护等场景。
+
+## 结语
