+chore: sync with llama.cpp upstream   
+```
+
+2. Update `CHANGELOG.md` with details on new features and bug fixes
+3. Increment `versionCode` and `versionName` in `build.gradle.kts` for `app` module
+4. Make a commit with the message,
+
+```
+release: prepare for release <new-version-number>
+```
+
+5. Create a new tag and push it to GitHub to initiate the CI pipeline for releasing,
+
+```bash
+git tag <new-version-number>
+git push origin --tags
+```
+
+## Deleting a Release/Tag from GitHub
+
+1. Delete the release from GitHub
