2. **Cập Nhật Phiên Bản** và **Changelog**: Đảm bảo cập nhật số phiên bản trong thư viện cũng như file `CHANGELOG.md` để phản ánh các thay đổi.

3. **Push Nhánh Phát Hành**: Đẩy nhánh phát hành mới lên repository từ xa.

    ```bash
git push origin releases/vX.X.X

5. **Push Tag**: Đẩy tag mới lên repository từ xa.

    ```bash
git push origin vX.X.X
