'alternative' is another possibility or choice.
"An alternative product release"
Eg: You could say "This is an alternative to product X. This product is cheaper and has similar features.
'upgrade' is a higher standard or quality of something.
"An upgraded product release"
Eg: You could say "This is very similar to our popular model X product but has been upgraded with newer features."
I hope this helps :)
"“Alternative”とは他の可能性や選択肢のことです。”An alternative product choice”(代わりの製品リリース) 例:”This is an alternative to product X. This product is cheaper and has similar features.”(これは代わりの商品Xです。この商品の方が低価格ですが同じような特徴があります。) “Upgrade”は何かがより高い標準や品質であることです。例:""This is very similar to our popular model X product but has been upgraded with newer features.”(これは人気のXモデルの商品ととても似ていますがより新しい特徴に改良されました)
ご参考にしていただければ幸いです。"
