Querida equipe da Unity por favor botem a versão da Unity 2018.3 para 32 bits e versões futuras também não esqueça o publico que usa 32 bits

Dear Unity team please download Unity 2018.3 for 32 bit and future versions also do not forget the public that uses 32 bits

 

I also think that Unity Technologies shouldn't have dropped the 32 bits version of their engine but they have.

The last 32 bits version is Unity 5.6.6 that you can find on the archive page, Unity 5.x tab: https://unity3d.com/get-unity/download/archive
