Release Magisk v25.2

`daemon_entry` calls `getprop` which initializes sysprop impl and checks whether we need to load persistent property file. On FDE devices, magiskd starts before /data is actually decrypted, and the check always fails. Thus `persist_getprop("persist.sys.safemode")` will always fail.

+## READ BEFORE OPENING ISSUES
+
+All bug reports require you to **USE DEBUG BUILDS**. Please include the version name and version code in the bug report.
+
+If you experience a bootloop, attach a `dmesg` (kernel logs) when the device refuse to boot. This may very likely require a custom kernel on some devices as `last_kmsg` or `pstore ramoops` are usually not enabled by default. In addition, please also upload the result of `cat /proc/mounts` when your device is working correctly **WITHOUT MAGISK**.
+
+If you experience issues during installation, in recovery, upload the recovery logs, or in Magisk, upload the install logs. Please also upload the `boot.img` or `recovery.img` that you are using for patching.
+
+If you experience a crash of Magisk app, dump the full `logcat` **when the crash happens**.
+
+If you experience other issues related to Magisk, upload `magisk.log`, and preferably also include a boot `logcat` (start dumping `logcat` when the device boots up)
+
+**DO NOT** open issues regarding root detection.
+
+**DO NOT** ask for instructions.
+
+**DO NOT** report issues if you have any modules installed.
+
+Without following the rules above, your issue will be closed without explanation.

 ## Bug Reports
 
-Canary Channels are cutting edge builds for those adventurous. To access canary builds, install the Canary Magisk Manager, switch to the Canary Channel in settings and upgrade.
-
-**Only bug reports from Canary builds will be accepted.**
+**Only bug reports from Debug builds will be accepted.**
 
 For installation issues, upload both boot image and install logs.<br>
 For Magisk issues, upload boot logcat or dmesg.<br>
-For Magisk Manager crashes, record and upload the logcat when the crash occurs.
+For Magisk app crashes, record and upload the logcat when the crash occurs.
 
 ## Building and Development
 
 - Magisk builds on any OS Android Studio supports. Install Android Studio and do the initial setups.
 - Clone sources: `git clone --recurse-submodules https://github.com/topjohnwu/Magisk.git`
 - Install Python 3.6+ \
-(Windows only: select **'Add Python to PATH'** in installer, and run `pip install colorama` after install)
+  (Windows only: select **'Add Python to PATH'** in installer, and run `pip install colorama` after install)
 - Configure to use the JDK bundled in Android Studio:
-	- macOS: `export JAVA_HOME="/Applications/Android Studio.app/Contents/jre/jdk/Contents/Home"`
-	- Linux: `export PATH="/path/to/androidstudio/jre/bin:$PATH"`
-	- Windows: Add `C:\Path\To\Android Studio\jre\bin` to environment variable `PATH`
+  - macOS: `export JAVA_HOME="/Applications/Android Studio.app/Contents/jre/Contents/Home"`
+  - Linux: `export PATH="/path/to/androidstudio/jre/bin:$PATH"`
+  - Windows: Add `C:\Path\To\Android Studio\jre\bin` to environment variable `PATH`
 - Set environment variable `ANDROID_SDK_ROOT` to the Android SDK folder (can be found in Android Studio settings)
 - Run `./build.py ndk` to let the script download and install NDK for you
 - To start building, run `build.py` to see your options. \
-For each action, use `-h` to access help (e.g. `./build.py all -h`)
-- To start development, open the project in Android Studio. Both app (Kotlin/Java) and native (C++/C) source code can be properly developed using the IDE, but *always* use `build.py` for building.
+  For each action, use `-h` to access help (e.g. `./build.py all -h`)
+- To start development, open the project with Android Studio. The IDE can be used for both app (Kotlin/Java) and native sources.
 - Optionally, set custom configs with `config.prop`. A sample `config.prop.sample` is provided.
-- To sign APKs and zips with your own private keys, set signing configs in `config.prop`. For more info, check [Google's Documentation](https://developer.android.com/studio/publish/app-signing.html#generate-key).
+
+## Signing and Distribution
+
+- The certificate of the key used to sign the final Magisk APK product is also directly embedded into some executables. In release builds, Magisk's root daemon will enforce this certificate check and reject and forcefully uninstall any non-matching Magisk apps to protect users from malicious and unverified Magisk APKs.
+- To do any development on Magisk itself, switch to an **official debug build and reinstall Magisk** to bypass the signature check.
+- To distribute your own Magisk builds signed with your own keys, set your signing configs in `config.prop`.
+- Check [Google's Documentation](https://developer.android.com/studio/publish/app-signing.html#generate-key) for more details on generating your own key.
