 # Changelog
 
+## 0.1.5

+- Fixed Unity 2021 compatibility for the obfuscated Runtime and Editor DLLs by removing invalid `System.Private.CoreLib` assembly references introduced during obfuscation.
+- Verified that Editor menu entry metadata remains available after the compatibility fix.
+- Expanded validation to catch Unity assembly load failures in addition to package resolve and compile errors.
+
 ## 0.1.4
 
 - Rebuilt Runtime and Editor DLLs with stricter obfuscation.

 Add the package through Unity Package Manager using this Git URL:
 
 ```text
-https://git.aisu.xin/aisu-sdk/si-m1-face-package.git#v0.1.4
+https://git.aisu.xin/aisu-sdk/si-m1-face-package.git#v0.1.5

 Or add it to `Packages/manifest.json`:
 
 ```json
-"xin.aisu.si-m1.face": "https://git.aisu.xin/aisu-sdk/si-m1-face-package.git#v0.1.4"
+"xin.aisu.si-m1.face": "https://git.aisu.xin/aisu-sdk/si-m1-face-package.git#v0.1.5"
 ```
 
 Unity may display Git packages as `xin.aisu.si-m1.face@<commit-hash>` in `Library/PackageCache`. This is expected for Git URL packages; the package version remains defined by `package.json`.
