 - **修正**：Folia 相关的线程与区域化问题、传送与末影珍珠、地狱门 ticket、实体同步等，对应文件名前缀多为 `Fix-*` / `Correct-*`。
 - **优化**：包含部分来自 Leaf、Gale、Purpur、Pufferfish、Lithium 等项目的移植与改写，对应 patch 文件名带有来源前缀；移植的准确性建议对照 patch 内容与原项目确认。
 - **配置系统**：自研的注解式配置框架（`shiroha-server/src/main/java/io/nanachiyo0721/shiroha/config/`），支持热重载与基于 dialog 的图形化配置界面，由 `/shirohaconfig` 命令操作（`shiroha-server/src/main/java/io/nanachiyo0721/shiroha/commands/config/`）。
-- **存档格式**：除原版 `.mca` 外支持 `linear` 与 `b_linear`（带缓冲刷写的 Linear）区域格式（`shiroha-server/src/main/java/io/nanachiyo0721/shiroha/enums/EnumRegionFormat.java`）。

 - **状态栏**：TPS、内存、区域信息状态栏，由 `/bar` 命令与配置控制（`shiroha-server/src/main/java/io/nanachiyo0721/shiroha/functions/bars/`）。
 - **其他**：实体唤醒时长、实体数量限制（Kaiiju）、传送门速率限制、CPU 亲和性等，详见对应 patch 与配置模块。

 - **Fixes**: Folia threading and regionization issues, teleport and ender pearl behavior, nether portal tickets, entity desync, etc. — patch filenames mostly use the `Fix-*` / `Correct-*` prefixes.
 - **Optimizations**: includes ports and reworkings taken from projects such as Leaf, Gale, Purpur, Pufferfish, and Lithium; these are marked with their source prefixes in patch filenames. Verify the patch contents against the original projects for attribution and accuracy.
 - **Config system**: a custom annotation-based configuration framework (`shiroha-server/src/main/java/io/nanachiyo0721/shiroha/config/`) with hot reload and a dialog-based GUI editor, operated through the `/shirohaconfig` command (`shiroha-server/src/main/java/io/nanachiyo0721/shiroha/commands/config/`).
-- **Region formats**: supports `linear` and `b_linear` (buffered-flush Linear) region formats in addition to vanilla `.mca` (`shiroha-server/src/main/java/io/nanachiyo0721/shiroha/enums/EnumRegionFormat.java`).
