Question about the API of 2.1.2/3

[Mickaël Véril (mveril)]

Hello I currently develop a rust framework for WSLPlugin and I currently add a new capability feature for it that list the capabilites associated to specific version mveril/wslplugins-rs#62
I seen the hooks for OnDistroRegistering and OnDistroUnregistering and the ExecuteBinaryInDistribution method are associated normally to the version 2.1.2 in the header but in the relase pannel of WSL it was associated to 2.1.3 and also the plugin sample that require the version 2.1.3.

Can you explain it please ?

Aslo in the release pannel the text talk about a ListDistribution method which are not listed in the API header.

WSL2 内存不释放 / 闲置休眠

WSL2 的内存由 Vmmem 管理：Linux 里 free 下降后，Windows 侧不一定马上还给宿主机；vmIdleTimeout 也主要影响实例空闲行为，不能保证长驻进程场景下内存一定按你预期保留。

建议排查

1. 看版本：wsl --version（旧版行为差很多）
2. %UserProfile%\.wslconfig 示例方向：

[wsl2]
memory=8GB
swap=4GB
# 按官方文档核对 vmIdleTimeout 等键是否仍适用你的版本

3. 主动回收：wsl --shutdown 后再开（会断开会话）
4. 长任务：避免在低内存机器上同时开多个重型 distro / Docker Desktop + 大模型

「Question about the API of 2.1.2/3」若是「实例被挂起」：确认没有节能/睡眠把虚拟机冻住；任务管理器里看 Vmmem 是否在压内存。

补充：WSL 版本号、是否 Docker Desktop、以及 free -h / 任务管理器截图（描述即可）会更好对症。
