-## Unreleased
+## v20240516
+
+### For all users
+
+Firefish is now compatible with [Node v22](https://nodejs.org/en/blog/announcements/v22-release-announce). The pre-built OCI container image will still be using the latest LTS version (v20.13.1 as of now).
+
+## v20240430
 
 ### For all users
 
 You can control the verbosity of the server log by adding `maxLogLevel` in `.config/default.yml`. `logLevels` has been deprecated in favor of this setting. (see also: <https://firefish.dev/firefish/firefish/-/blob/eac0c1c47cd23789dcc395ab08b074934409fd96/.config/example.yml#L152>)
 
+### For systemd/pm2 users
+
+- You need to install Perl to build Firefish. Since Git depends on Perl in many packaging systems, you probably already have Perl installed on your system. You can check the Perl version by this command:
+  ```sh
+	perl --version
+	```
+- Not only Firefish but also Node.js has recently fixed a few security issues:
+  - https://nodejs.org/en/blog/vulnerability/april-2024-security-releases
+  - https://nodejs.org/en/blog/vulnerability/april-2024-security-releases-2
+
+  So, it is highly recommended that you upgrade your Node.js version as well. The new versions are
+    - Node v18.20.2 (v18.x LTS)
+    - Node v20.12.2 (v20.x LTS)
+    - Node v21.7.3 (v21.x)
+
+  You can check your Node.js version by this command:
+    ```sh
+    node --version
+    ```
+  [Node v22](https://nodejs.org/en/blog/announcements/v22-release-announce) was also released several days ago, but we have not yet tested Firefish with this version.
